Exhibit 99.1 NEWS RELEASE FOR IMMEDIATE RELEASE www.abraxaspetroleum.com FOR MORE INFORMATION CONTACT: CHRIS WILLIFORD, EVP/CFO ABRAXAS PETROLEUM CORPORATION NETS $34 MILLION ON SALE OF CERTAIN WYOMING ASSETS SAN ANTONIO, TX - (March 31, 2000) - Abraxas Petroleum Corporation (OTC Bulletin Board: AXAS) announced today the sale of a group of non-core properties, the assets held by Abraxas Wamsutter L.P., as well as certain other contiguous assets. Abraxas received approximately $34 million in cash for its interests, subject to certain post closing adjustments, further strengthening Abraxas' balance sheet. The sale will result in Abraxas booking a gain in the first quarter 2000 of $33 million with a corresponding increase in book equity. Proceeds will be used to fund Abraxas' 2000 capital expenditure program which is focused primarily on horizontal exploitation of existing properties. The sale validates Abraxas' joint venture approach to non-core properties. Abraxas owned a 1% interest in Abraxas Wamsutter L.P. which under the terms of the partnership agreement, increased as certain rate of return requirements of the L.P. were satisfied. As a result of the sale, the receipt of Abraxas' back-in value for these properties was greatly accelerated. The sale included interests in 57 natural gas wells and gross leasehold of approximately 15,000 acres. The properties are located in Sweetwater and Carbon Counties, Wyoming. The buyer of the properties is Samson Resources Company, a private Tulsa, Oklahoma-based oil and gas company. Abraxas originally sold these properties to Abraxas Wamsutter L.P. in November 1998. Abraxas Petroleum Corporation is a San Antonio-based crude oil and natural gas exploration and production company that also processes natural gas. It operates primarily along the Texas Gulf Coast, in the Permian Basin of western Texas, western Canada and Wyoming. Safe Harbor for forward-looking statement: Statements in this release looking forward in time involve known and unknown risks and uncertainties, which may cause the Company's actual results in future periods to be materially different from any future performance suggested in this release. Such factors may include, but may not be necessarily limited to, changes in the prices received by the Company for crude oil and natural gas. In addition, the Company's future crude oil and natural gas production is highly dependent upon the Company's level of success in acquiring or finding additional reserves. Further, the Company operates in an industry sector where securities values are highly volatile and may be influenced by economic and other factors beyond the Company's control. In the context of forward-looking information provided for in this release, reference is made to the discussion of risk factors detailed in the Company's filing with the Securities and Exchange Commission during the past 12 months.

Each party shall be entitled to inspect and obtain a copy of relevant documents in the possession or control of the other party and to take depositions of the other parties' employees, agents, representatives and witnesses (including expert witnesses). All such discovery shall be in accordance with procedures approved by the arbitrator(s). Unless otherwise provided in the award, each party shall bear its own costs of discovery. All discovery shall be expedited, consistent with the nature and complexity of the claim or dispute and consistent with fairness and justice. The arbitrator(s) shall have the power to compel any party to comply with discovery requests of the other parties and to issue binding orders relating to any discovery dispute which shall be enforceable in the same manner as awards. The arbitrator(s) also shall have the power to impose sanctions for abuse or frustration of the arbitration process, including without limitation, the refusal to comply with orders of the arbitrator(s) relating to discovery and compliance with subpoenas. Each of the parties hereto hereby irrevocably submits to the jurisdiction of the courts of the State of Texas for entry of any arbitration decision or to obtain any preliminary relief which may be necessary and hereby consents to the enforcement by such courts of any award rendered in such arbitration. 2.4 Payment Method.

(ii) The rights and remedies of the Parties with respect to environmental conditions on the Interests on which the Parties cannot agree on curative measures or a Sale Price adjustment are as follows: (a) If the collective value of the environmental conditions is less than 1% of the Sale Price, the Parties will be obligated to proceed with Closing as to all of the Interests without curative action by Seller with respect to such environmental conditions and without an adjustment to the Sale Price. (b) If the collective value of the environmental conditions equals or exceeds 1% of the Sale Price, the Parties may refer the matter to a mutually agreed upon third party expert for determination. The determination of such expert shall be binding on the Parties, and the Sale Price will be reduced by the positive difference, if any, between the determined value of the environmental conditions and one percent (1%) of the Sale Price. The Parties will be obligated to proceed with Closing, subject to the termination rights of the Parties under Article 6 and subpart (d) of this Section 5.3.3. (c) If the collective value of the environmental conditions equals or exceeds 1% of the Sale Price, and the Parties agree with respect to the existence of such conditions and the value thereof, the Sale Price will be reduced by the positive difference, if any, between the agreed upon value of the environmental conditions and one percent (1%) of the Sale Price, and the Parties will be obligated to proceed with Closing, subject to the termination rights of the Parties under Article 6 and subpart (d) of this Section 5.3.3. (d) If the collective value of the environmental conditions equals or exceeds 25% of the Sale Price, either Party may terminate this Agreement, and neither party will have any further obligation to conclude the transfer of the Interests under this Agreement. However, the right of termination under this subpart (d) must be exercised no later than 3 business days before Closing, after which both Parties will be deemed to have waived their termination rights under this subpart (d) in connection with environmental conditions. (iii) Subject to any agreement by Buyer and Seller to cure an environmental condition and notwithstanding any agreement by Buyer and Seller to reduce the Sale Price due to an environmental condition with respect to the Interests, or any other provision of this Agreement, Buyer at Closing will assume all environmental obligations with respect to the Interests, as provided in Section 8.2. 5.4 Government Approvals. 5.4.1 Title Pending Governmental Approvals. Until Seller and Buyer obtain any necessary federal, state and Indian approvals of the assignment of Leases or other Interests requiring such approval, Seller will continue to hold record title to such Leases or other Interests as nominee for Buyer. If Seller continues to operate the Interests pending such approval, Seller and Buyer will have the rights and obligations with respect to the operation of the Interests set forth in Section 11.3. 5.4.2 Denial of Required Government Approvals. If any required approval is finally denied, Seller shall pay Buyer the Allocated Value of the affected Leases or other affected Interests, and Buyer shall immediately reassign such Leases or other Interests to Seller and Seller shall reimburse Buyer for (i) an amount equal to its operating expenses minus its revenues related to the affected Interests and (ii) other expenditures incurred by Buyer on such affected Interests incurred between the Effective Date and the date of such reassignment. 5.5 Preferential Rights and Consents to Assign. 5.5.1 Notices to Holders.

Seller will not be liable to Buyer if any Preferential Rights are exercised, or any Consents are denied, except as expressly provided in this Section 5.5. 5.5.2 Remedies Before Closing . If Seller is unable before Closing to obtain the required Consents (other than Consents ordinarily obtained after closing and Consents on hydrocarbon sales, purchase, gathering, transportation, treating, marketing, exchange, processing and fractionating agreements) and waivers of all Preferential Rights, then: (i) Seller and Buyer by agreement may proceed with Closing as to the Interests affected by the unwaived Preferential Rights or unobtained Consents, subject to the further obligations of Seller and Buyer set forth in Section 5.5.3 in the event that such Preferential Rights are validly exercised or such Consents are ultimately denied after Closing; (ii) Either Seller or Buyer may exclude the affected portion of the Interests from the transaction under this Agreement, adjust the Sale Price by the Allocated Value of the excluded Interests, and proceed with Closing as to the rest of the Interests; or (iii) In addition to the remedies set forth in subparts (i) and (ii) of this Section 5.5.2, Buyer may exercise the termination rights set forth in Article 6. 5.5.3 Remedies After Closing. (i) Preferential Rights. After Closing, if (a) any holder of Preferential Rights alleges improper notice of sale, or (b) Seller or Buyer discover, or any third party alleges, the existence of additional Preferential Rights, Seller and Buyer will attempt to obtain waivers of those discovered or alleged Preferential Rights. If Seller and Buyer are unable to obtain waivers of such Preferential Rights, or the third party ultimately establishes and exercises its rights, and such exercise denies the Interests to Buyer, then Buyer and Seller will rescind the assignment of the affected Interests under this Agreement, after which Seller shall pay Buyer the Allocated Value of the affected Interests, and Buyer shall immediately reassign the affected Interests to the Seller. Rescission of the assignment of the affected Interests and receipt of the Allocated Value of the affected Interests shall be Buyer's sole remedy if undiscovered or alleged Preferential Rights are exercised or Consents are denied after Closing; provided, however, that Seller shall reimburse Buyer for (i) an amount equal to its operating expenses minus its revenues relating to the affected Interests and (ii) other expenditures incurred by Buyer on such affected Interests between the Effective Date and the date of such rescission.

Rescission of the assignment of the affected Interests and receipt of the Allocated Value of the affected Interests shall be Buyer's sole remedy if undiscovered or alleged Preferential Rights are exercised or Consents are denied after Closing; provided, however, that Seller shall reimburse Buyer for (i) an amount equal to its operating expenses minus its revenues relating to the affected Interests and (ii) other expenditures incurred by Buyer on such affected Interests between the Effective Date and the date of such rescission. 5.6 Title Defects. 5.6.1 Definition of Title Defect.

Upon the discovery of a Title Defect by Buyer, Buyer shall immediately notify Seller in writing. Any such notice by Buyer shall include appropriate evidence and documentation to substantiate its position and shall be delivered to Seller on or before five (5) days prior to Closing Date (the "Title Claim Date").

(iii) If an uncured, unwaived Title Defect reduces the value of the Interest affected by an amount equal to or more than one percent (1%) of the Allocated Value of the affected Interest, the Parties will attempt to agree on the value of the Title Defect. If the Parties are unable to agree as to whether the Title Defect exists or the value thereof, Seller and Buyer may refer the matter to a mutually agreeable third party expert for determination. The determination of such expert shall be binding on the Parties. Seller and Buyer shall reduce the Sale Price by the value agreed upon by the Parties or determined by the expert (as applicable) if the determined value exceeds one percent (1%) of the Allocated Value of the affected Interest and proceed with Closing.

In the event Seller fails to designate and the qualified intermediary fails to acquire the Exchange Property within such time periods, the agency or trust shall terminate and the proceeds then held by the qualified intermediary shall be paid immediately to Seller. The rights and responsibilities of Seller, Buyer and the qualified intermediary shall be documented with such agreements containing such terms and provisions as shall be determined by Seller to be necessary to accomplish a tax free exchange under Section 1031 of the Code subject, however, to the limitations on costs and liabilities of Buyer set forth below. If Seller makes a tax deferred exchange election, Buyer shall not be obligated to pay any additional costs or incur any additional obligations in the acquisition of the Interests. Seller shall indemnify, defend and hold Buyer harmless from and against any and all Claims to the extent same are the result of or are attributable to (i) any transactions undertaken by Seller pursuant to this Section 12.11 and (ii) any act or omission of Seller relating to any transaction contemplated by this Section 12.11. 12.12 Tax Deferred Exchange Election by Buyer. Buyer may, at or before the Closing, acquire the Interests as a like-kind exchange pursuant to Section 1031 of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, with respect to any or all of the Interests. The rights and responsibilities of Seller, Buyer and the qualified intermediary shall be documented with such agreements containing such terms and provisions as shall be determined by Buyer to be necessary to accomplish a tax free exchange under Section 1031 of the Code subject, however, to the limitations on costs and liabilities of Seller set forth below. If Buyer makes a tax deferred exchange election, Seller shall not be obligated to pay any additional costs or incur any additional obligations in the sale of the Interests. Buyer shall indemnify, defend and hold Seller harmless from and against any and all Claims to the extent same are the result of or are attributable to (i) any transactions undertaken by Buyer pursuant to this Section 12.12 and (ii) any act or omission of Buyer relating to any transaction contemplated by this Section 12.12. 12.13 Severability. If any provision of this Agreement is found by a court of competent jurisdiction to be invalid or unenforceable, that provision will be deemed modified to the extent necessary to make it valid and enforceable and if it cannot be so modified, it shall be deemed deleted and the remainder of the Agreement shall continue and remain in full force and effect. 12.14 Counterparts. This Agreement may be executed in counterparts, each of which shall constitute an original and all of which shall constitute one document. 12.15 Governing Law. This Agreement is governed by and must be construed according to the laws of the State of Texas, excluding any conflicts-of-law rule or principle that might apply the law of another jurisdiction. 12.16 Dispute Resolution. If a dispute arises between the Parties under this Agreement and cannot be resolved by negotiation, the Parties agree to submit the dispute to mediation before resorting to litigation. Either Party may request mediation of a dispute by sending a written request to the other Party. If either Party requests mediation of a dispute, the Parties agree to choose a mutually acceptable mediator, promptly begin mediation of the dispute, and share the costs of all mediation services equally. Each Party agrees to have present at all mediation conferences at least one individual who has authority to settle the dispute. Notwithstanding this agreement to mediate disputes, either Party may file a complaint for statute of limitation or venue reasons, or seek a preliminary injunction or other provisional judicial relief, if in its sole judgment such action is necessary to avoid irreparable damage or to preserve the status quo. Despite any such protective action, the Parties will continue to try to resolve the dispute by negotiation or mediation. 12.17 Production Imbalances. Set forth in Exhibit E attached hereto and made a part hereof for all purposes is a listing of all gas imbalance volumes measured in MMBTUs and liquid imbalance volumes measured in gallons and the aggregate net volume of overproduction or underproduction, as applicable, attributable to the Interests as of the Effective Date. The Parties acknowledge that the imbalances assumed at Closing may be incorrect, and Buyer and Seller agree that the Sale Price will be adjusted, for any differences at $2.00 per mmbtu for gas imbalances and $.35 per gallon for liquid imbalances. The right to claim an adjustment under this Section 12.17 will expire 150 days after closing. Buyer will be solely responsible for any liability and solely entitled to any benefit from production imbalances relating to the Interests and arising from and after the Closing Date. 12.18 Exhibits. In the event of a conflict between the provisions of the Exhibits attached to this Agreement and the foregoing provisions of this Agreement, the provisions of this Agreement shall take precedence. The omission of certain provisions of this Agreement from any conveyance delivered pursuant hereto does not constitute a conflict between this Agreement and said conveyance document and will not effect a merger of the omitted provisions. 12.19 Obligations of Seller.
