(the "Partnership" or "Registrant") was organized as a Delaware limited partnership on August 31, 1993. The offering of limited partnership interests began October 25, 1993, as part of a shelf offering registered under the name Southwest Royalties Institutional 1992-93 Income Program. Minimum capital requirements for the Partnership were met on December 8, 1993 and concluded August 20, 1994. The Partnership has no subsidiaries. As of December 31, 1996, the Partnership had utilized approximately $2,008,600 of limited partner capital contributions to acquire interests in oil and gas properties. All excess capital, $89,489, and the associated organization costs of $3,132, has been distributed to the limited partners in proportion to their capital contributions as a return of capital. The principal executive offices of the Partnership are located at 407 N. Big Spring, Suite 300, Midland, Texas, 79701. The Managing General Partner of the Partnership, Southwest Royalties, Inc. (the "Managing General Partner") and its staff of 98 individuals, together with certain independent consultants used on an "as needed" basis, perform various services on behalf of the Partnership, including the selection of oil and gas properties and the marketing of production from such properties. H. H. Wommack, III, a stockholder, director, President and Treasurer of the Managing General Partner, is also a general partner. The Partnership has no employees. Principal Products, Marketing and Distribution The Partnership has acquired and holds royalty interest and net profit interests in oil and gas properties located in New Mexico and Texas. All activities of the Partnership are confined to the continental United States. All oil and gas produced from these properties is sold to unrelated third parties in the oil and gas business. The revenues generated from the Partnership's oil and gas activities are dependent upon the current market for oil and gas. With some periodic exceptions, since the early 1980's, there has been a worldwide oversupply of oil; therefore, market prices have declined significantly. The prices received by the Partnership for its oil and gas production depend upon numerous factors beyond the Partnership's control, including competition, economic, political and regulatory developments and competitive energy sources, and make it particularly difficult to estimate future prices for oil and natural gas. During 1998 oil prices fell to their lowest daily levels since 1986 and to their lowest annual average since 1976. In two years, oil prices have been sliced by more than half. The factors that started the decline in oil prices in 1997 are the same ones that have kept them down in 1998. It was believed that there would be continued heavy consumption coming from the Asian region, but the collapse of their markets late in 1997 carried over to this year bringing demand down with it. Asian consumption had all but disappeared in 1998, creating an oversupply of crude oil on the market. That drop in demand has lasted longer than anyone had anticipated, but hopes of a recovery abound. Another reason for the continued drop in prices has been OPEC's unwillingness to completely comply with production cuts established in March and again in June. Although they have been near 90% compliance at times, they have also been below 70% on a monthly basis. Even a four-day bombing in December of Iraqi military sites could create only a one-day rally in oil prices. Crude oil closed December 31, 1998 at $12.05 per barrel on the NYMEX and posted prices closed at $9.50 per barrel. In a year of fairly optimistic expectations for gas prices, the average price of natural gas wound up declining in 1998 to its lowest level since 1995. Although the nationwide average did remain above $2.00 per MMBTU, 1998's prices were approximately 17% lower than those seen in 1997. The combination of mild weather throughout the year and a gas storage surplus both contributed to the low prices. Analysts' predictions for 1999 prices vary, ranging from a low of $1.87 per MMBTU to a high of $2.40 per MMBTU. Reduced production throughout the U.S. industry, along with large gas storage withdrawals during the first weeks of January 1999, are both key factors in our belief that the 1999 average gas price will remain around $1.80 per MMBTU level. Following is a table of the ratios of revenues received from oil and gas production for the last three years: Oil Gas 1998 46% 54% 1997 48% 52% 1996 53% 47% As the table indicates, the Partnership's revenue is almost evenly divided between its oil and gas production. The Partnership revenues will be highly dependent upon the future prices and demands for oil and gas. Seasonality of Business Although the demand for natural gas is highly seasonal, with higher demand in the colder winter months and in very hot summer months, the Partnership has been able to sell all of its natural gas, either through contracts in place or on the spot market at the then prevailing spot market price. As a result, the volume sold by the Partnership is not expected to fluctuate materially with the change of season. Customer Dependence No material portion of the Partnership's business is dependent on a single purchaser, or a very few purchasers, where the loss of one would have a material adverse impact on the Partnership. Two purchasers accounted for 72% of the Partnership's total oil and gas production during 1998: Navajo Refining Company for 39% and American Processing for 33%. Two purchasers accounted for 71% of the Partnership's total oil and gas production during 1997: Navajo Refining Company, Inc. for 36%, and American Processing for 35%. Two purchasers accounted for 69% of the Partnership's total oil and gas production during 1996: Navajo Refining Company, Inc. 41%, and American Processing 28%. All purchasers of the Partnership's oil and gas production are unrelated third parties. In the event any of these purchasers were to discontinue purchasing the Partnership's production, the Managing General Partner believes that a substitute purchaser or purchasers could be located without undue delay. No other purchaser accounted for an amount equal to or greater than 10% of the Partnership's sales of oil and gas production. Competition Because the Partnership has utilized all of its funds available for the acquisition of interests in producing oil and gas properties, it is not subject to competition from other oil and gas property purchasers. See Item 2, Properties. Factors that may adversely affect the Partnership include delays in completing arrangements for the sale of production, availability of a market for production, rising operating costs of producing oil and gas and complying with applicable water and air pollution control statutes, increasing costs and difficulties of transportation, and marketing of competitive fuels. Moreover, domestic oil and gas must compete with imported oil and gas and with coal, atomic energy, hydroelectric power and other forms of energy. Regulation Oil and Gas Production - The production and sale of oil and gas is subject to federal and state governmental regulation in several respects, such as existing price controls on natural gas and possible price controls on crude oil, regulation of oil and gas production by state and local governmental agencies, pollution and environmental controls and various other direct and indirect regulation. Many jurisdictions have periodically imposed limitations on oil and gas production by restricting the rate of flow for oil and gas wells below their actual capacity to produce and by imposing acreage limitations for the drilling of wells. The federal government has the power to permit increases in the amount of oil imported from other countries and to impose pollution control measures. Various aspects of the Partnership's oil and gas activities will be regulated by administrative agencies under statutory provisions of the states where such activities are conducted and by certain agencies of the federal government for operations on Federal leases. Moreover, certain prices at which the Partnership may sell its natural gas production are controlled by the Natural Gas Policy Act of 1978, the Natural Gas Wellhead Decontrol Act of 1989 and the regulations promulgated by the Federal Energy Regulatory Commission. Environmental - The Partnership's oil and gas activities will be subject to extensive federal, state and local laws and regulations governing the generation, storage, handling, emission, transportation and discharge of materials into the environment. Governmental authorities have the power to enforce compliance with their regulations, and violations carry substantial penalties. This regulatory burden on the oil and gas industry increases its cost of doing business and consequently affects its profitability. The Managing General Partner is unable to predict what, if any, effect compliance will have on the Partnership. Industry Regulations and Guidelines - Certain industry regulations and guidelines apply to the registration, qualification and operation of oil and gas programs in the form of limited partnerships. The Partnership is subject to these guidelines which regulate and restrict transactions between the Managing General Partner and the Partnership. The Partnership complies with these guidelines and the Managing General Partner does not anticipate that continued compliance will have a material adverse effect on Partnership operations. Partnership Employees The Partnership has no employees; however the Managing General Partner has a staff of geologists, engineers, accountants, landmen and clerical staff who engage in Partnership activities and operations and perform additional services for the Partnership as needed. In addition to the Managing General Partner's staff, the Partnership engages independent consultants such as petroleum engineers and geologists as needed. As of December 31, 1998 there were 98 individuals directly employed by the Managing General Partner in various capacities. Item 2. Properties In determining whether an interest in a particular producing property was to be acquired, the Managing General Partner considered such criteria as estimated oil and gas reserves, estimated cash flow from the sale of production, present and future prices of oil and gas, the extent of undeveloped and unproved reserves, the potential for secondary, tertiary and other enhanced recovery projects and the availability of markets. As of December 31, 1998, the Partnership possessed an interest in oil and gas properties located in Eddy County of New Mexico; Andrews, Dawson, Howard, Midland, Reeves, Schleicher, Stonewall, Upton, Ward and Winkler Counties of Texas. These properties consist of various interests in 77 wells and units. Due to the Partnership's objective of maintaining current operations without engaging in the drilling of any developmental or exploratory wells, or additional acquisitions of producing properties, there has not been any significant changes in properties during 1998, 1997 and 1996. During 1998, five leases were sold for approximately $600. In compliance with the Partnership Agreement, if the Partnership should purchase a producing property from the Managing General Partner, such purchase price would be prior cost, adjusted for any intervening operation. If such adjusted cost was greater than fair market value, or if specific cost was unable to be determined, such purchase price would be fair market value as determined by an independent reservoir engineer. Significant Properties The following table reflects the significant properties in which the Partnership has an interest: Date Purchased No. of Proved Reserves* Name and Location and Interest Wells Oil (bbls) Gas (mcf) - ----------------- ------------ ------ --------- --------- Custer & Wright 11/94 at 28 7,000 467,000 Winkler County, 1% to 40% Texas net profits interests Michael Dingman 9/94 at 42 15,000 95,000 Midland, Stonewall, .5% to 50% Reeves, Dawson, net profits Schleicher, Winkler interests Ward, Andrews, Counties, Texas: Eddy County, New Mexico *Ryder Scott Company Petroleum Engineers prepared the reserve and present value data for 96.4% of the Partnership's existing properties as of January 1, 1999. Another independent petroleum engineer prepared the remaining 3.6% of the Partnership's properties. The reserve estimates were made in accordance with guidelines established by the Securities and Exchange Commission pursuant to Rule 4-10(a) of Regulation S-X. Such guidelines require oil and gas reserve reports to be prepared under existing economic and operating conditions with no provisions for price and cost escalation except by contractual arrangements. The New York Mercantile Exchange price at December 31, 1998 of $12.50 was used as the beginning basis for the oil price. Oil price adjustments from $12.50 per barrel were made in the individual evaluations to reflect oil quality, gathering and transportation costs. The results are an average price received at the lease of $10.26 per barrel in the preparation of the reserve report as of January 1, 1999. In the determination of the gas price, the New York Mercantile Exchange price at December 31, 1998 of $1.95 was used as the beginning basis. Gas price adjustments from $1.95 per Mcf were made in the individual evaluations to reflect BTU content, gathering and transportation costs and gas processing and shrinkage. The results are an average price received at the lease of $1.43 per Mcf in the preparation of the reserve report as of January 1, 1999. As also discussed in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, oil and gas prices were subject to frequent changes in 1998. The evaluation of oil and gas properties is not an exact science and inevitably involves a significant degree of uncertainty, particularly with respect to the quantity of oil or gas that any given property is capable of producing. Estimates of oil and gas reserves are based on available geological and engineering data, the extent and quality of which may vary in each case and, in certain instances, may prove to be inaccurate. Consequently, properties may be depleted more rapidly than the geological and engineering data have indicated. Unanticipated depletion, if it occurs, will result in lower reserves than previously estimated; thus an ultimately lower return for the Partnership. Basic changes in past reserve estimates occur annually. As new data is gathered during the subsequent year, the engineer must revise his earlier estimates. A year of new information, which is pertinent to the estimation of future recoverable volumes, is available during the subsequent year evaluation. In applying industry standards and procedures, the new data may cause the previous estimates to be revised. This revision may increase or decrease the earlier estimated volumes. Pertinent information gathered during the year may include actual production and decline rates, production from offset wells drilled to the same geologic formation, increased or decreased water production, workovers, and changes in lifting costs among others. Accordingly, reserve estimates are often different from the quantities of oil and gas that are ultimately recovered. The Partnership has reserves which are classified as proved developed producing, proved developed non-producing and proved undeveloped. All of the proved reserves are included in the engineering reports which evaluate the Partnership's present reserves. Because the Partnership does not engage in drilling activities, the development of proved undeveloped reserves is conducted pursuant to farmout arrangements with the Managing General Partner or unrelated third parties. Generally, the Partnership retains a carried interest such as an overriding royalty interest under the terms of a farmout, or receives cash. The Partnership or the owners of properties in which the Partnership owns an interest can engage in workover projects or supplementary recovery projects, for example, to extract behind the pipe reserves which qualify as proved developed non-producing reserves. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operation. Item 3. Legal Proceedings There are no material pending legal proceedings to which the Partnership is a party. Item 4. Submission of Matters to a Vote of Security Holders No matter was submitted to a vote of security holders during the fourth quarter of 1998 through the solicitation of proxies or otherwise. Part II Item 5. Market for the Registrant's Common Equity and Related Stockholder Matters Market Information Limited partnership interests, or units, in the Partnership are currently being offered and sold for a price of $500. Limited partner units are not traded on any exchange and there is no public or organized trading market for them. Further, a transferee may not become a substitute limited partner without the consent of the Managing General Partner. The Managing General Partner has the right, but not the obligation, to purchase limited partnership units should an investor desire to sell. The value of the unit is determined by adding the sum of (1) current assets less liabilities and (2) the present value of the future net revenues attributable to proved reserves and by discounting the future net revenues at a rate not in excess of the prime rate charged by NationsBank, N.A. of Midland, Texas plus one percent (1%), which value shall be further reduced by a risk factor discount of no more than one-third (1/3) to be determined by the Managing General Partner in its sole and absolute discretion. As of December 31, 1998, 1997 and 1996, no limited partner units were purchased by the Managing General Partner. Number of Limited Partner Interest Holders As of December 31, 1998, there were 176 holders of limited partner units in the Partnership. Distributions Pursuant to Article III, Section 3.05 of the Partnership's Certificate and Agreement of Limited Partnership, "Net Cash Flow" shall be distributed to the partners on a monthly basis. "Net Cash Flow" is defined as "the cash generated by the Partnership's investments in producing oil and gas properties, less (i) General and Administrative Costs, (ii) Direct Costs, (iii) Operating Costs, and (iv) any reserves necessary to meet current and anticipated needs of the Partnership, as determined in the sole discretion of the Managing General Partner." During 1998, distributions were made totaling $58,500, with $52,650 distributed to the limited partners and $5,850 to the general partners. For the year ended December 31, 1998, distributions of $10.85 per limited partner unit were made, based upon 4,851 limited partner units outstanding. The decline in distributions experienced in 1998 will be expected to continue into 1999 based on the continued low oil price economy. During 1997, twelve monthly distributions were made totaling $300,600, with $270,540 distributed to the limited partners and $30,060 to the general partners. For the year ended December 31, 1997, distributions of $55.77 per limited partner unit were made, based upon 4,851 limited partner units outstanding. During 1996, twelve monthly distributions were made totaling $338,739, with $314,239 distributed to the limited partners and $24,500 to the general partners. For the year ended December 31, 1996, distributions of $64.78 per limited partner unit were made, based upon 4,851 limited partner units outstanding. Item 6. Selected Financial Data The following selected financial data for the years ended December 31 1998, 1997, 1996, 1995 and 1994 should be read in conjunction with the financial statements included in Item 8: Years ended December 31, ---------------------------------------- 1998 1997 1996 1995 1994 ---- ---- ---- ---- ---- Revenues $ 2,205 304,410 395,095 251,501 150,925 Net income (loss) (462,692) (467,687) 180,841 (99,700) 87,328 Partners' share of net income (loss): General partners (4,630) 25,491 34,555 19,946 10,522 Limited partners (458,062) (493,178) 146,286(119,646) 76,806 Limited partners' net income (loss) per unit (94.43) (101.67) 30.16 (24.66) 15.83 Limited partner's cash distribution per unit 10.85 55.77 64.78 45.14 9.89 Total assets $ 388,507 909,626 1,677,9071,835,8342,184,955 Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations General Southwest Royalties Institutional Income Fund XI-B, L.P. was organized as a Delaware limited partnership on August 31, 1993. The offering of limited partnership interests began October 25, 1993, as part of a shelf offering registered under the name Southwest Royalties Institutional 1992-93 Income Program. Minimum capital requirements for the Partnership were met on December 8, 1993, and the Offering Period terminated August 20, 1994 with 174 limited partners purchasing 4,851 units for $2,425,500. The Partnership was formed to acquire non-operating interests in producing oil and gas properties, to produce and market crude oil and natural gas produced from such properties and to distribute any net proceeds from operations to the general and limited partners. Net revenues from producing oil and gas properties will not be reinvested in other revenue producing assets except to the extent that producing facilities and wells are reworked or where methods are employed to improve or enable more efficient recovery of oil and gas reserves. The economic life of the Partnership will thus depend on the period over which the Partnership's oil and gas reserves are economically recoverable. Increases or decreases in Partnership revenues and, therefore, distributions to partners will depend primarily on changes in the prices received for production, changes in volumes of production sold, lease operating expenses, enhanced recovery projects, offset drilling activities pursuant to farmout arrangements and on the depletion wells. Since wells deplete over time, production can generally be expected to decline from year to year. Well operating costs and general and administrative costs usually decrease with production declines; however, these costs may not decrease proportionately. Net income available for distribution to the limited partners has fluctuated over the past few years and is expected to fluctuate in later years based on these factors. Based on current conditions, management anticipates performing no workovers during 1999 to enhance production. With expected price improvement, workovers may be performed in the year 2001. The partnership may have an increase in the year 2001, otherwise, the Partnership will most likely experience it's historical decline of approximately 14% per year. Results of Operations A. General Comparison of the Years Ended December 31, 1998 and 1997 The following table provides certain information regarding performance factors for the years ended December 31, 1998 and 1997: Year Ended Percentage December 31, Increase 1998 1997 (Decrease) ---- ---- --------- Average price per barrel of oil $ 11.68 19.37 (40%) Average price per mcf of gas $ 1.52 2.22 (32%) Oil production in barrels 9,800 11,400 (14%) Gas production in mcf 87,300 109,000 (20%) Income from net profits interests $ 31,907 206,956 (85%) Partnership distributions $ 58,500 300,600 (81%) Limited partner distributions $ 52,650 270,540 (81%) Per unit distribution to limited partners $ 10.85 55.77 (81%) Number of limited partner units 4,851 4,851 Revenues The Partnership's income from net profits interests decreased to $31,907 from $206,956 for the years ended December 31, 1998 and 1997, respectively, a decrease of 85%. The principal factors affecting the comparison of the years ended December 31, 1998 and 1997 are as follows: 1. The average price for a barrel of oil received by the Partnership decreased during the year ended December 31, 1998 as compared to the year ended December 31, 1997 by 40%, or $7.69 per barrel, resulting in a decrease of approximately $87,700 in income from net profits interests. Oil sales represented 46% of total oil and gas sales during the year ended December 31, 1998 as compared to 48% during the year ended December 31, 1997. The average price for an mcf of gas received by the Partnership decreased during the same period by 32%, or $.70 per mcf, resulting in a decrease of approximately $76,300 in income from net profits interests. The total decrease in income from net profits interests due to the change in prices received from oil and gas production is approximately $164,000. The market price for oil and gas has been extremely volatile over the past decade and management expects a certain amount of volatility to continue in the foreseeable future. 2. Oil production decreased approximately 1,600 barrels or 14% during the year ended December 31, 1998 as compared to the year ended December 31, 1997, resulting in a decrease of approximately $18,700 in income from net profits interests. Gas production decreased approximately 21,700 mcf or 20% during the same period, resulting in a decrease of approximately $33,000 in income from net profits interests. The total decrease in income from net profits interests due to the change in production is approximately $51,700. The decrease in oil and gas production is primarily due to property sales and a gas plant explosion which stopped production in March and April of 1998. 3. Lease operating costs and production taxes were 16% lower, or approximately $41,000 less during the year ended December 31, 1998 as compared to the year ended December 31, 1997. The decrease in lease operating costs are primarily in relation to property sales. 4. As of December 31, 1998, miscellaneous expense was approximately $30,159. The Partnership entered into a purchase agreement on the Tar Baby lease that guaranteed net income each month from October 1994 through January 1998. This income was recorded on the Partnerships books as miscellaneous income. Based on new information obtained in May 1998, an adjustment of $52,706 was found to be necessary. This adjustment was recorded as miscellaneous expense on the Partnerships books for the quarter ended June 30, 1998. Costs and Expenses Total costs and expenses decreased to $464,897 from $772,097 for the years ended December 31, 1998 and 1997, respectively, a decrease of 40%. The decrease is the result of lower depletion expense, provision for impairment and general and administrative costs. 1. General and administrative costs consists of independent accounting and engineering fees, computer services, postage, and Managing General Partner personnel costs. General and administrative costs decreased 2% or approximately $1,000 during the year ended December 31, 1998 as compared to the year ended December 31, 1997. 2. Depletion expense decreased to $130,000 for the year ended December 31, 1998 from $226,000 for the same period in 1997. This represents a decrease of 42%. Depletion is calculated using the units of revenue method of amortization based on a percentage of current period gross revenues to total future gross oil and gas revenues, as estimated by the Partnership's independent petroleum consultants. A contributing factor to the decrease in depletion expense between the comparative periods was the decrease in the price of oil and gas used to determine the Partnership's reserves for January 1, 1998 as compared to 1997. Another contributing factor was due to the impact of revisions of previous estimates on reserves. Revisions of previous estimates can be attributed to the changes in production performance, oil and gas price and production costs. The impact of the revision would have increased depletion expense approximately $30,000 as of December 31, 1997. The Partnership reduced the net capitalized costs of oil and gas properties in 1998 by approximately $279,567. The write-down has the effect of reducing net income, but did not affect cash flow or partner distributions. Results of Operations B. General Comparison of the Years Ended December 31, 1997 and 1996 The following table provides certain information regarding performance factors for the years ended December 31, 1997 and 1996: Year Ended Percentage December 31, Increase 1997 1996 (Decrease) ---- ---- --------- Average price per barrel of oil $ 19.37 20.65 (6%) Average price per mcf of gas $ 2.22 2.15 3% Oil production in barrels 11,400 15,400 (26%) Gas production in mcf 109,000 133,300 (18%) Income from net profits interests $ 206,956 315,055 (34%) Partnership distributions $ 300,600 338,739 (11%) Limited partner distributions $ 270,540 314,239 (14%) Per unit distribution to limited partners $ 55.77 64.78 (14%) Number of limited partner units 4,851 4,851 Revenues The Partnership's income from net profits interests decreased to $206,956 from $315,055 for the years ended December 31, 1997 and 1996, respectively, a decrease of 34%. The principal factors affecting the comparison of the years ended December 31, 1997 and 1996 are as follows: 1. The average price for a barrel of oil received by the Partnership decreased during the year ended December 31, 1997 as compared to the year ended December 31, 1996 by 6%, or $1.28 per barrel, resulting in a decrease of approximately $19,700 in income from net profits interests. Oil sales represented 48% of total oil and gas sales during the year ended December 31, 1997 as compared to 53% during the year ended December 31, 1996. The average price for an mcf of gas received by the Partnership increased during the same period by 3%, or $.07 per mcf, resulting in an increase of approximately $9,300 in income from net profits interests. The net total decrease in income from net profits interests due to the change in prices received from oil and gas production is approximately $10,400 . The market price for oil and gas has been extremely volatile over the past decade and management expects a certain amount of volatility to continue in the foreseeable future. 2. Oil production decreased approximately 4,000 barrels or 26% during the year ended December 31, 1997 as compared to the year ended December 31, 1996, resulting in a decrease of approximately $77,500 in income from net profits interests. Gas production decreased approximately 24,300 mcf or 18% during the same period, resulting in a decrease of approximately $53,900 in income from net profits interests. The total decrease in income from net profits interests due to the change in production is approximately $131,400. The decrease in production is primarily attributable to downtime experienced on two wells, one well being shut-in and normal decline. 3. Lease operating costs and production taxes were 12% lower, or approximately $33,300 less during the year ended December 31, 1997 as compared to the year ended December 31, 1996. Decrease is due primarily to pulling expense incurred on one well in 1996 and post closing costs recorded in 1996 on the purchase of the Kaiser State #44. 4. As of December 31, 1997, miscellaneous income was approximately $94,424. The income is a result of a purchase agreement, on the Tar Baby lease, that guarantees the Partnership a net income of approximately $3,400 each month from October 1994 to January 1998. Costs and Expenses Total costs and expenses increased to $772,097 from $214,254 for the years ended December 31, 1997 and 1996, respectively, an increase of 260%. The increase is the result of higher depletion expense and a provision for impairment of oil and gas properties. 1. General and administrative costs consists of independent accounting and engineering fees, computer services, postage, and Managing General Partner personnel costs. General and administrative costs increased 2% or approximately $800 during the year ended December 31, 1997 as compared to the year ended December 31, 1996. 3. Depletion expense increased to $226,000 for the year ended December 31, 1997 from $158,000 for the same period in 1996. This represents an increase of 43%. Depletion is calculated using the units of revenue method of amortization based on a percentage of current period gross revenues to total future gross oil and gas revenues, as estimated by the Partnership's independent petroleum consultants. A contributing factor to the increase in depletion expense between the comparative periods was the decrease in the price of oil and gas used to determine the Partnership's reserves for January 1, 1998 as compared to 1997. Another contributing factor was due to the impact of revisions of previous estimates on reserves. Revisions of previous estimates can be attributed to the changes in production performance, oil and gas price and production costs. The impact of the revision would have increased depletion expense approximately $98,000 as of December 31, 1996. The Partnership reduced the net capitalized costs of oil and gas properties in 1997 by approximately $489,154. The write-down has the effect of reducing net income, but did not affect cash flow or partner distributions. C. Revenue and Distribution Comparison Partnership income or (loss) for the years ended December 31, 1998, 1997 and 1996 was $(462,692), $(467,687) and $180,841, respectively. Excluding the effects of depreciation, depletion, amortization and provision for impairment, net income (loss) would have been $(46,305) in 1998, $254,907 in 1997 and $346,439 in 1996. Correspondingly, Partnership distributions for the years ended December 31, 1998, 1997 and 1996 were $58,500, $300,600 and $338,739, respectively. These differences are indicative of the changes in oil and gas prices, production and property. The source for the 1998 distributions of $58,500 were oil and gas operations of approximately $55,200, and the change in oil and gas properties of approximately $600, with the balance from available cash on hand at the beginning of the period. The source for the 1997 distributions of $300,600 were oil and gas operations of approximately $285,200, with the balance from available cash on hand at the beginning of the period. The sources for the 1996 distributions of $338,739 were oil and gas operations of approximately $259,900, the refund of organization cost of approximately $3,100 and excess capital of approximately $89,500, resulting in excess cash for contingencies or subsequent distributions. Total distributions during the year ended December 31, 1998 were $58,500 of which $52,650 was distributed to the limited partners and $5,850 to the general partners. The per unit distribution to limited partners during the same period was $10.85. Total distributions during the year ended December 31, 1997 were $300,600 of which $270,540 was distributed to the limited partners and $30,060 to the general partners. The per unit distribution to limited partners during the same period was $55.77. Total distributions during the year ended December 31, 1996 were $338,739 of which $314,239 was distributed to the limited partners and $24,500 to the general partners. The per unit distribution to limited partners during the same period was $64.78. Since inception of the Partnership, cumulative monthly cash contributions of $989,439 have been made to the partners. As of December 31,1998 $904,353 or $186.43 per limited partner unit, has been distributed to the limited partners, representing a 37% return of the capital contributed. Liquidity and Capital Resources The primary source of cash is from operations, the receipt of income from net profits interests in oil and gas properties. The Partnership knows of no material change, nor does it anticipate any such change. Cash flows provided by operating activities were approximately $55,200 in 1998 compared to $285,200 in 1997 and approximately $259,900 in 1996. The primary source of the 1998 cash flow from operating activities was profitable operations. Cash flows from investing activities were approximately $600 in 1998. The Partnership had no cash flows from investing activities in 1997. Cash flows from investing activities were approximately $3,100 in 1996. Cash flows used in financing activities were approximately $58,400 in 1998 compared to $300,500 in 1997 and approximately $338,800 in 1996. The only 1998 use in financing activities was the distribution to partners. As of December 31, 1998, the Partnership had approximately $7,100 in working capital. The Managing General Partner knows of no other commitments and believes the revenues generated from operations will be adequate to meet the operating needs of the Partnership. Liquidity - Managing General Partner The Managing General Partner has a highly leveraged capital structure with over $21.0 million of interest payments due in 1999 on its debt obligations. Due to severely depressed commodity prices, the Managing General Partner is experiencing difficulty in generating sufficient cash flow to meet its obligations and sustain its operations. The Managing General Partner is currently in the process of renegotiating the terms of its various obligations with its creditors and/or attempting to seek new lenders or equity investors. Additionally, the Managing General Partner would consider disposing of certain assets in order to meet its obligations. There can be no assurance that the Managing General Partner's debt restructuring efforts will be successful or that the lenders will agree to a course of action consistent with the Managing General Partners requirements in restructuring the obligations. Even if such agreement is reached, it may require approval of additional lenders, which is not assured. Furthermore, there can be no assurance that the sales of assets can be successfully accomplished on terms acceptable to the Managing General Partner. Under current circumstances, the Managing General Partner's ability to continue as a going concern depends upon its ability to (1) successfully restructure its obligations or obtain additional financing as may be required, (2) maintain compliance with all debt covenants, (3) generate sufficient cash flow to meet its obligations on a timely basis, and (4) achieve satisfactory levels of future earnings. If the Managing General Partner is unsuccessful in its efforts, it may be unable to meet its obligations making it necessary to undertake such other actions as may be appropriate to preserve asset values. Information Systems for the Year 2000 The Managing General Partner provides all data processing needs of the Partnership. The Managing General Partner is continuing in its effort to identify and assess its exposure to the potential Year 2000 software and imbedded chip processing and date sensitivity issue. Through the Managing General Partners data processing subsidiary, Midland Southwest Software, Inc., the Managing General Partner proactively initiated a plan to identify applicable hardware and software, assess impact and effect, estimate costs, construct and implement corrective actions, and prepare contingency plans. Identification & Assessment The Managing General Partner currently believes it has identified the internal and external software and hardware that may have date sensitivity problems. Four critical systems and/or functions were identified: (1) the proprietary software of the Partnership (OGAS) that is used for oil & gas property management and financial accounting functions, (2) the DEC VAX/VMS hardware and operating system, (3) various third-party application software including lease economic analysis, fixed asset management, geological applications, and payroll/human resource programs, and (4) External Agents. The proprietary software of the Partnership is currently in process of meeting compliance requirements with an estimated completion date of mid- year 1999. Since this is an internally generated software package, the Managing General Partner has estimated the cost to be approximately $25,000 by estimating the necessary man-hours. These modifications are being made by internal staff and do not represent additional costs to the Partnership. The Managing General Partner has not made contingency plans at this time since the conversion is ahead of schedule and being handled by Managing General Partner controlled internal programmers. Given the complexity of the systems being modified, it is anticipated that some problems may arise, but with an expected early completion date, the Managing General Partner feels that adequate time is available to overcome unforeseen delays. DEC has released a fully compliant version of its operating system that is used by the Partnership on the DEC VAX system. It will be installed in August 1999, the Managing General Partner believes that this will solve any potential problems on the system. The Managing General Partner has identified various third-party software that may have date sensitivity problems and is working with the vendors to secure solutions as well as prepare contingency plans. After review and evaluation of the vendor plans and status, the Managing General Partner believes that the problems will be resolved prior to the year 2000 or the alternate contingency plan will sufficiently and adequately remediate the problem so that there is no material disruption to business functions. The External Agents of the Partnership include suppliers, customers, owners, vendors, banks, product purchasers including pipelines, and other oil and gas property operators. The Managing General Partner is in the process of identifying and communicating with each critical External Agent about its plan and progress thereof in addressing the Year 2000 issue. This process is on schedule and the Managing General Partner, at this time, believes that there should be no material interference or disruption associated with any of the critical External Agent's functions necessary to the Partnership's business. The Managing General Partner estimates completion of this audit by mid-year 1999 and believes that alternate plans can be devised to circumvent any material problems arising from critical External Agent noncompliance. Cost To date, the Managing General Partner has incurred only minimal internal man-hour costs for identification, planning, and maintenance. The Managing General Partner believes that the necessary additional costs will also be minimal and most will fall under normal and general maintenance procedures and updates. An accurate cost cannot be determined at this time, but it is expected that the total cost to remediate all systems to be less than $50,000. Risks/Contingency The failure to correct critical systems of the Partnership, or the failure of a material business partner or External Agent to resolve critical Year 2000 issues could have a serious adverse impact on the ability of the Partnership to continue operations and meet obligations. Based on the Managing General Partner's evaluation and assessment to date, it is believed that any interruption in operation will be minor and short-lived and pose no material monetary loss, safety, or environmental risk to the Partnership. However, until all assessment is complete, it is impossible to accurately identify the risks, quantify potential impacts or establish a final contingency plan. The Managing General Partner believes that its assessment and contingency planning will be complete no later than mid-year 1999. Worst Case Scenario The Securities and Exchange Commission requires that public companies must forecast the most reasonably likely worst case Year 2000 scenario, assuming that the Managing General Partner's Year 2000 plan is not effective. Analysis of the most reasonably likely worst case Year 2000 scenarios the Partnership may face leads to contemplation of the following possibilities which, though considered highly unlikely, must be included in any consideration of worst cases: widespread failure of electrical, gas, and similar supplies by utilities serving the Partnership; widespread disruption of the services of communications common carriers; similar disruption to means and modes of transportation for the Partnership and its employees, contractors, suppliers, and customers; significant disruption to the Partnership's ability to gain access to, and continue working in, office buildings and other facilities; and the failure, of third-parties systems, the effects of which would have a cumulative material adverse impact on the Partnership's critical systems. The Partnership could experience an inability by customers, traders, and others to pay, on a timely basis or at all, obligations owed to the Partnership. Under these circumstances, the adverse effect on the Partnership, and the diminution of Partnership revenues, could be material, although not quantifiable at this time. Item 8.

Southwest Royalties Institutional Income Fund XI-B, L.P. (a Delaware limited partnership) Notes to Financial Statements 1. Organization Southwest Royalties Institutional Income Fund XI-B, L.P. was organized under the laws of the state of Delaware on August 31, 1993, for the purpose of acquiring producing oil and gas properties and to produce and market crude oil and natural gas produced from such properties for a term of 50 years, unless terminated at an earlier date as provided for in the Partnership Agreement. The Partnership will sell its oil and gas production to a variety of purchasers with the prices it receives being dependent upon the oil and gas economy. Southwest Royalties, Inc. serves as the Managing General Partner and H. H. Wommack, III, as the individual general partner. Partnership profits and losses, as well as all items of income, gain, loss, deduction, or credit, will be credited or charged as follows: Limited General Partner Partners (1) ------- -------- Organization and offering expenses (2) 100% - Acquisition costs 100% - Operating costs 90% 10% Administrative costs (3) 90% 10% Direct costs 90% 10% All other costs 90% 10% Interest income earned on capital contributions 100% - Oil and gas revenues 90% 10% All other revenues 90% 10% Amortization 100% - Depletion allowances 100% - (1) H.H. Wommack, III, President of the Managing General Partner, is an additional general partner in the Partnership and has a one percent interest in the Partnership. Mr. Wommack is the majority stockholder of the Managing General Partner whose continued involvement in Partnership management is important to its operations. Mr. Wommack, as a general partner, shares also in Partnership liabilities. (2) Organization and Offering Expenses (including all cost of selling and organizing the offering) include a payment by the Partnership of an amount equal to three percent (3%) of Capital Contributions for reimbursement of such expenses. All Organization Costs (which excludes sales commissions and fees) in excess of three percent (3%) of Capital Contributions with respect to the Partnership will be allocated to and paid by the Managing General Partner. (3) Administrative Costs will be paid from the Partnership's revenues; however; Administrative Costs in the Partnership year in excess of two percent (2%) of Capital Contributions shall be allocated to and paid by the Managing General Partner. Southwest Royalties Institutional Income Fund XI-B, L.P. (a Delaware limited partnership) Notes to Financial Statements 2. Summary of Significant Accounting Policies Oil and Gas Properties Oil and gas properties are accounted for at cost under the full-cost method. Under this method, all productive and nonproductive costs incurred in connection with the acquisition, exploration and development of oil and gas reserves are capitalized. Gain or loss on the sale of oil and gas properties is not recognized unless significant oil and gas reserves are involved. The Partnership's policy for depreciation, depletion and amortization of oil and gas properties is computed under the units of revenue method. Under the units of revenue method, depreciation, depletion and amortization is computed on the basis of current gross revenues from production in relation to future gross revenues, based on current prices, from estimated production of proved oil and gas reserves. Under the units of revenue method, the Partnership computes the provision by multiplying the total unamortized cost of oil and gas properties by an overall rate determined by dividing (a) oil and gas revenues during the period by (b) the total future gross oil and gas revenues as estimated by the Partnership's independent petroleum consultants. It is reasonably possible that those estimates of anticipated future gross revenues, the remaining estimated economic life of the product, or both could be changed significantly in the near term due to the potential fluctuation of oil and gas prices or production. The depletion estimate would also be affected by this change. Should the net capitalized costs exceed the estimated present value of oil and gas reserves, discounted at 10%, such excess costs would be charged to current expense. The Partnership reduced the net capitalized costs of oil and gas properties in 1998 by approximately $279,567. This write-down has the effect of reducing net income, but did not affect cash flow or partnership distributions. As of December 31, 1996, the net capitalized costs did not exceed the estimated value of oil and gas reserves. The Partnership's interest in oil and gas properties consists of net profits interests in proved properties located within the continental United States. A net profits interest is created when the owner of a working interest in a property enters into an arrangement providing that the net profits interest owner will receive a stated percentage of the net profit from the property. The net profits interest owner will not otherwise participate in additional costs and expenses of the property. Southwest Royalties Institutional Income Fund XI-B, L.P. (a Delaware limited partnership) Notes to Financial Statements 2. Summary of Significant Accounting Policies - continued Estimates and Uncertainties The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Organization Costs Organization costs are stated at cost and are amortized over sixty months using the straight-line method. Syndication Costs Syndication costs are accounted for as a reduction of partnership equity. Environmental Costs The Partnership is subject to extensive federal, state and local environmental laws and regulations. These laws, which are constantly changing, regulate the discharge of materials into the environment and may require the Partnership to remove or mitigate the environmental effects of the disposal or release of petroleum or chemical substances at various sites. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Costs which improve a property as compared with the condition of the property when originally constructed or acquired and costs which prevent future environmental contamination are capitalized. Expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Liabilities for expenditures of a non-capital nature are recorded when environmental assessment and/or remediation is probable, and the costs can be reasonably estimated. Gas Balancing The Partnership utilizes the sales method of accounting for gas- balancing arrangements. Under this method the Partnership recognizes sales revenue on all gas sold. As of December 31, 1998, 1997 and 1996, there were no significant amounts of imbalance in terms of units and value. Income Taxes No provision for income taxes is reflected in these financial statements, since the tax effects of the Partnership's income or loss are passed through to the individual partners. In accordance with the requirements of Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes," the Partnership's tax basis in its oil and gas properties at December 31, 1998 and 1997 is $558,051 more and $306,929 less than that shown on the accompanying Balance Sheet in accordance with generally accepted accounting principles. Southwest Royalties Institutional Income Fund XI-B, L.P. (a Delaware limited partnership) Notes to Financial Statements 2. Summary of Significant Accounting Policies - continued Cash and Cash Equivalents For purposes of the statement of cash flows, the Partnership considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. The Partnership maintains its cash at one financial institution. Number of Limited Partner Units As of December 31, 1998, 1997 and 1996 there were 4,851 limited partner units outstanding held by 176 partners. Concentrations of Credit Risk The Partnership is subject to credit risk through trade receivables. Although a substantial portion of its debtors' ability to pay is dependent upon the oil and gas industry, credit risk is minimized due to a large customer base. All partnership revenues are received by the Managing General Partner and subsequently remitted to the partnership and all expenses are paid by the Managing General Partner and subsequently reimbursed by the partnership. Fair Value of Financial Instruments The carrying amount of cash and accounts receivable approximates fair value due to the short maturity of these instruments. Net Income (loss) per limited partnership unit The net income (loss) per limited partnership unit is calculated by using the number of outstanding limited partnership units. 3. Liquidity - Managing General Partner The Managing General Partner has a highly leveraged capital structure with over $21.0 million of interest payments due in 1999 on its debt obligations. Due to severely depressed commodity prices, the Managing General Partner is experiencing difficulty in generating sufficient cash flow to meet its obligations and sustain its operations. The Managing General Partner is currently in the process of renegotiating the terms of its various obligations with its creditors and/or attempting to seek new lenders or equity investors. Additionally, the Managing General Partner would consider disposing of certain assets in order to meet its obligations. There can be no assurance that the Managing General Partner's debt restructuring efforts will be successful or that the lenders will agree to a course of action consistent with the Managing General Partners requirements in restructuring the obligations. Even if such agreement is reached, it may require approval of additional lenders, which is not assured. Furthermore, there can be no assurance that the sales of assets can be successfully accomplished on terms acceptable to the Managing General Partner. Under current circumstances, the Managing General Partner's ability to continue as a going concern depends upon its ability to (1) successfully restructure its obligations or obtain additional financing as may be required, (2) maintain compliance with all debt covenants, (3) generate sufficient cash flow to meet its obligations on a timely basis, and (4) achieve satisfactory levels of future earnings. If the Managing General Partner is unsuccessful in its efforts, it may be unable to meet its obligations making it necessary to undertake such other actions as may be appropriate to preserve asset values. Southwest Royalties Institutional Income Fund XI-B, L.P. (a Delaware limited partnership) Notes to Financial Statements 4. Commitments and Contingent Liabilities The Managing General Partner has the right, but not the obligation, to purchase limited partnership units should an investor desire to sell. The value of the unit is determined by adding the sum of (1) current assets less liabilities and (2) the present value of the future net revenues attributable to proved reserves and by discounting the future net revenues at a rate not in excess of the prime rate charged by NationsBank, N.A. of Midland, Texas plus one percent (1%), which value shall be further reduced by a risk factor discount of no more than one- third (1/3) to be determined by the Managing General Partner in its sole and absolute discretion. The Partnership is subject to various federal, state and local environmental laws and regulations which establish standards and requirements for protection of the environment. The Partnership cannot predict the future impact of such standards and requirements, which are subject to change and can have retroactive effectiveness. The Partnership continues to monitor the status of these laws and regulations. As of December 31, 1998, the Partnership has not been fined, cited or notified of any environmental violations and management is not aware of any unasserted violations which would have a material adverse effect upon capital expenditures, earnings or the competitive position in the oil and gas industry. However, the Managing General Partner does recognize by the very nature of its business, material costs could be incurred in the near term to bring the Partnership into total compliance. The amount of such future expenditures is not reliably determinable due to several factors, including the unknown magnitude of possible contaminations, the unknown timing and extent of the corrective actions which may be required, the determination of the Partnership's liability in proportion to other responsible parties and the extent to which such expenditures are recoverable from insurance or indemnifications from prior owners of Partnership's properties. Southwest Royalties Institutional Income Fund XI-B, L.P. (a Delaware limited partnership) Notes to Financial Statements 5. Related Party Transactions A significant portion of the oil and gas properties in which the Partnership has an interest are operated by and purchased from the Managing General Partner. As is usual in the industry and as provided for in the operating agreement for each respective oil and gas property in which the Partnership has an interest, the operator is paid an amount for administrative overhead attributable to operating such properties, with such amounts to Southwest Royalties, Inc. as operator approximating $54,700, $56,000 and $57,200 for the years ended December 31, 1998, 1997 and 1996, respectively. In addition, the Managing General Partner and certain officers and employees may have an interest in some of the properties that the Partnership also participates. Certain subsidiaries or affiliates of the Managing General Partner perform various oilfield services for properties in which the Partnership owns an interest. Such services aggregated approximately $600, $700 and $3,000 for the years ended December 31, 1998, 1997 and 1996, respectively, and the Managing General Partner believes that these costs are comparable to similar charges paid by the Partnership to unrelated third parties. Southwest Royalties, Inc., the Managing General Partner, was paid $33,711 in 1998, $42,000 during 1997 and 40,896 during 1996, as an administrative fee for indirect general and administrative overhead expenses. Receivables from Southwest Royalties, Inc., the Managing General Partner, of approximately $4,796 and $54,454 are from oil and gas production, net of lease operating costs and production taxes, as of December 31, 1998 and 1997, respectively. In addition, a director and officer of the Managing General Partner is a partner in a law firm, with such firm providing legal services to the Partnership. There were no legal services for the years ended December 31, 1998 and 1997. As of December 31, 1996 there were approximately $90 in legal services. 6. Major Customers No material portion of the Partnership's business is dependent on a single purchaser, or a very few purchasers, where the loss of one would have a material adverse impact on the Partnership. Two purchasers accounted for 72% of the Partnership's total oil and gas production during 1998: Navajo Refining Company for 39% and American Processing for 33%. Two purchasers accounted for 71% of the Partnership's total oil and gas production during 1997: Navajo Refining Company, Inc. 36%, and American Processing 35%. Two purchasers accounted for 69% of the Partnership's total oil and gas production during 1996: Navajo Refining Company, Inc. 41%, and American Processing 28%. All purchasers of the Partnership's oil and gas production are unrelated third parties. In the event any of these purchasers were to discontinue purchasing the Partnership's production, the Managing General Partner believes that a substitute purchaser or purchasers could be located without undue delay. No other purchaser accounted for an amount equal to or greater than 10% of the Partnership's sales of oil and gas production. Southwest Royalties Institutional Income Fund XI-B, L.P.

Estimated Oil and Gas Reserves (unaudited) The Partnership's interest in proved oil and gas reserves is as follows: Oil (bbls) Gas (mcf) ---------- --------- Proved developed and undeveloped reserves - January 1, 1996 131,000 1,467,000 Revisions of previous estimates 13,000 113,000 Production (15,000) (133,000) ------- --------- December 31, 1996 129,000 1,447,000 Revisions of previous estimates (60,000) (552,000) Production (11,000) (109,000) ------- --------- December 31, 1997 58,000 786,000 Sales of reserves in place (2,000) (1,000) Revisions of previous estimates (24,000) (60,000) Production (10,000) (87,000) ------- --------- December 31, 1998 22,000 638,000 ======= ========= Proved developed reserves - December 31, 1996 122,000 1,428,000 ======= ========= December 31, 1997 53,000 771,000 ======= ========= December 31, 1998 22,000 626,000 ======= ========= All of the Partnership's reserves are located within the continental United States. *Ryder Scott Company Petroleum Engineers prepared the reserve and present value data for 96.4% of the Partnership's existing properties as of January 1, 1999. Another independent petroleum engineer prepared the remaining 3.6% of the Partnership's properties. The reserve estimates were made in accordance with guidelines established by the Securities and Exchange Commission pursuant to Rule 4-10(a) of Regulation S-X. Such guidelines require oil and gas reserve reports to be prepared under existing economic and operating conditions with no provisions for price and cost escalation except by contractual arrangements. The New York Mercantile Exchange price at December 31, 1998 of $12.05 was used as the beginning basis for the oil price. Oil price adjustments from $12.05 per barrel were made in the individual evaluations to reflect oil quality, gathering and transportation costs. The results are an average price received at the lease of $10.25 per barrel in the preparation of the reserve report as of January 1, 1999. In the determination of the gas price, the New York Mercantile Exchange price at December 31, 1998 of $1.95 was used as the beginning basis. Gas price adjustments from $1.95 per Mcf were made in the individual evaluations to reflect BTU content, gathering and transportation costs and gas processing and shrinkage. The results are an average price received at the lease of $1.43 per Mcf in the preparation of the reserve report as of January 1, 1999. Southwest Royalties Institutional Income Fund XI-B, L.P. (a Delaware limited partnership) Notes to Financial Statements 7. Estimated Oil and Gas Reserves (unaudited) - continued The evaluation of oil and gas properties is not an exact science and inevitably involves a significant degree of uncertainty, particularly with respect to the quantity of oil or gas that any given property is capable of producing. Estimates of oil and gas reserves are based on available geological and engineering data, the extent and quality of which may vary in each case and, in certain instances, may prove to be inaccurate. Consequently, properties may be depleted more rapidly than the geological and engineering data have indicated. Unanticipated depletion, if it occurs, will result in lower reserves than previously estimated; thus an ultimately lower return for the Partnership. Basic changes in past reserve estimates occur annually. As new data is gathered during the subsequent year, the engineer must revise his earlier estimates. A year of new information, which is pertinent to the estimation of future recoverable volumes, is available during the subsequent year evaluation. In applying industry standards and procedures, the new data may cause the previous estimates to be revised. This revision may increase or decrease the earlier estimated volumes. Pertinent information gathered during the year may include actual production and decline rates, production from offset wells drilled to the same geologic formation, increased or decreased water production, workovers, and changes in lifting costs among others. Accordingly, reserve estimates are often different from the quantities of oil and gas that are ultimately recovered. The Partnership has reserves which are classified as proved developed producing, proved developed non-producing and proved undeveloped. All of the proved reserves are included in the engineering reports which evaluate the Partnership's present reserves. Because the Partnership does not engage in drilling activities, the development of proved undeveloped reserves is conducted pursuant to farmout arrangements with the Managing General Partner or unrelated third parties. Generally, the Partnership retains a carried interest such as an overriding royalty interest under the terms of a farmout, or receives cash. Southwest Royalties Institutional Income Fund XI-B, L.P.

Estimated Oil & Gas Reserves (unaudited) - continued The standardized measure of discounted future net cash flows relating to proved oil and gas reserves at December 31, 1998, 1997 and 1996 is presented below: 1998 1997 1996 ---- ---- ---- Future cash inflows, net of production and development costs $ 593,000 1,104,000 4,409,000 10% annual discount for estimated timing of cash flows 212,000 313,000 1,692,000 --------- --------- --------- Standardized measure of discounted future net cash flows $ 381,000 791,000 2,717,000 ========= ========= ========= The principal sources of change in the standardized measure of discounted future net cash flows for the years ended December 31, 1998, 1997 and 1996 are as follows: 1998 1997 1996 ---- ---- ---- Sales of oil and gas produced, net of production costs $ (32,000) (207,000) (580,000) Changes in prices and production costs (210,000)(1,560,000) 1,642,000 Changes of production rates (timing) and others (135,000) 212,000 78,000 Revisions of previous quantities estimates (103,000) (643,000) (357,000) Accretion of discount 79,000 272,000 269,000 Discounted future net cash flows - Sales of minerals in place (9,000) - - Beginning of year 791,000 2,717,000 1,665,000 --------- --------- --------- End of year $ 381,000 791,000 2,717,000 ========= ========= ========= Future net cash flows were computed using year-end prices and costs that related to existing proved oil and gas reserves in which the Partnership has mineral interests. Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure On June 9, 1997 Southwest Royalties, Inc. the Partnership's Managing General Partner (Southwest Royalties, Inc.) dismissed Joseph Decosimo and Company as the Partnership's independent accountants. The Managing General Partner's Board of Directors approved the decision to change the Partnership's independent accountants. The report of Joseph Decosimo and Company on the financial statements for the fiscal year ended December 31, 1996 contained no adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principle. In connection with its audit for the fiscal year ended December 31, 1996 and through June 9, 1997, there have been no disagreements with Joseph Decosimo and Company on any matter of accounting principles or practices, financial statements disclosure, or auditing scope or procedure, which disagreements if not resolved to the satisfaction of Joseph Decosimo and Company would have caused them to make reference thereto in their report on the financial statements for such year. The Registrant has requested that Joseph Decosimo and Company furnish it with a letter addressed to the SEC stating whether or not is agrees with the above statements. A copy of that letter is included as Exhibit 16 and has been filed with the Securities and Exchange Commission. Part III Item 10.
