Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited consolidated financial statements of CARBO Ceramics Inc. have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required for complete financial statements. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. The results of the interim periods presented herein are not necessarily indicative of the results to be expected for any other interim period or the full year. The consolidated balance sheet as of December 31, 2016 has been derived from the audited financial statements at that date. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2016 included in the annual report on Form 10-K of CARBO Ceramics Inc. for the year ended December 31, 2016. The consolidated financial statements include the accounts of CARBO Ceramics Inc. and its operating subsidiaries (the “Company”). All significant intercompany transactions have been eliminated. Beginning in late 2014, a severe decline in oil and natural gas prices led to a significant decline in oil and natural gas industry drilling activities and capital spending. As a result of the continued negative impact this has had on its business, the Company continues to operate its plants at significantly reduced levels. As of September 30, 2017, the Company was producing ceramic proppants from its Eufaula, Alabama manufacturing facility, and processing sand at its Marshfield, Wisconsin facility. The Company produces ceramic pellets for the industrial markets in a limited capacity, and when market demands, at our McIntyre, Georgia facility. Our Millen, Georgia facility is currently mothballed, and we do not expect to resume production or complete the second line of the facility. We are currently using our Toomsboro, Georgia facility in a limited capacity to process minerals for third parties. The Company has been in 2017 and continues to be focused on diversifying its revenue streams to more frac sand, technology and industrial ceramics, and mineral processing. As a result of the steps the Company has taken to enhance its liquidity, the Company currently believes that cash on hand will enable the Company to meet its working capital, capital expenditure, debt service and other funding requirements for at least one year from the date of this Form 10-Q. The Company’s view regarding sufficiency of cash and liquidity is primarily based on our financial forecast for the remainder of 2017 and 2018, which is impacted by various assumptions regarding demand and sales prices for our products. Although the Company has observed certain factors in the first nine months of 2017 that could be indicative of improving industry conditions, its financial forecasts in recent periods have not always been accurate due to the inability to estimate customer demand, which is highly volatile in the current operating environment. The Company has no committed sales backlog from its customers. As a result, there is no guarantee that its financial forecast, which projects sufficient cash will be available to meet planned operating expenses and other cash needs, will be achieved. Additionally, the construction projects relating to the second production line at Millen, Georgia and the second phase of the retrofit of an existing plant with the KRYPTOSPHERE® technology remain suspended. During the three months ended September 30, 2017, we recorded an impairment on the Millen, Georgia facility (see Note 1 - Long-lived and other noncurrent assets impairment Deferred Taxes – Valuation Allowance Accounting Standards Codification (“ASC”) Topic 740, Income Taxes, provides the carrying value of deferred tax assets should be reduced by the amount not expected to be realized. A company should reduce deferred tax assets by a valuation allowance if, based on the weight of all available evidence, it is not more likely than not that some portion or all of the deferred tax assets will be realized. The valuation allowance should be sufficient to reduce the deferred tax asset to the amount that is more likely than not to be realized. ASC 740 requires all available evidence, both positive and negative, be considered to determine whether a valuation allowance for deferred tax assets is needed in the financial statements. Additionally there can be statutory limitations and losses also assessed on the deferred tax assets should certain conditions arise. Restricted Cash As a result of the repayment of the Wells Fargo term loan, combined with the continued use of letters of credit and corporate cards with Wells Fargo (see Note 8), a portion of the Company’s cash balance is now restricted to its use in order to provide collateral to Wells Fargo. As of September 30, 2017 and December 31, 2016, restricted cash was $10,216 and $0, respectively. Lower of Cost or Market Adjustments As of September 30, 2017, the Company reviewed the carrying values of all inventories and concluded that no adjustments were warranted for finished goods and raw materials intended for use in the Company’s manufacturing process. As of September 30, 2016, the Company reviewed the carrying values of all inventories and concluded that certain sand inventories were impacted by changes in market conditions. Consequently, during the nine-month period ended September 30, 2016, the Company recognized a $115 loss in cost of sales to adjust the carrying value to the lower market prices on certain sand inventories. Manufacturing Production Levels Below Normal Capacity As a result of the Company substantially reducing manufacturing production levels, including by idling certain facilities, certain production costs have been expensed instead of being capitalized into inventory. The Company expenses fixed production overhead amounts in excess of amounts that would have been allocated to each unit of production at normal production levels. For the three months ended September 30, 2017 and 2016, the Company expensed $10,890 and $12,845, respectively, in production costs. For the nine months ended September 30, 2017 and 2016, the Company expensed $32,899 and $36,067, respectively, in production costs. Long-lived and other noncurrent assets impairment As noted, throughout 2017 and 2016, the Company has temporarily idled production at various manufacturing facilities. The Company does not assess temporarily idled assets for impairment unless events or circumstances indicate that the carrying amounts of those assets may not be recoverable. Short-term stoppages of production for less than one year do not generally significantly impact the long-term expected cash flows of the idled facility. At December 31, 2016, as a result of the continued severity of the market downturn, the Company identified indicators of impairments related to each of its domestic manufacturing plant asset groups. The Company completed undiscounted cash flow analyses on that date and determined no impairment charge was necessary at that time. As of September 30, 2017, the Company concluded that the Company’s Toomsboro and Millen, Georgia facilities should no longer be evaluated together as a group of assets because the facilities are no longer interchangeable and will not manufacture like products. As a result of the sustained and long-term shift away from base ceramic proppant to less expensive frac sand, the Company has made a strategic decision to focus on growing technology, industrial and mineral processing revenue streams. Our Toomsboro, Georgia plant is being repurposed to produce technology and industrial products, as well as for use in toll processing of minerals. Our Millen, Georgia facility is currently only able to produce base ceramic proppants, but given our current long-term outlook on base ceramic proppant demand, we do not expect to utilize this plant to produce base ceramic proppant. We are currently evaluating opportunities to monetize our assets at our Millen facility. As a result, we evaluated the Toomsboro and Millen, Georgia plants separately for indicators of impairment during the third quarter of 2017. Given the change in the asset groupings of the two facilities and lack of estimated future cash flows associated with the base ceramic production at the Millen facility, the Company identified indicators of impairment at the Millen, Georgia facility as of September 30, 2017. The Company determined that the projected cash flows attributable to our Millen, Georgia facility did not exceed the carrying value of the assets; therefore the Company concluded there was an impairment at that facility. The Company engaged the services of a third party consulting firm to assist with the determination of the fair market value of the related assets and concluded that the assets were impaired. The key assumptions and inputs impacting the fair value include third party market data with respect to the property and equipment at our Millen facility as well as at comparable facilities. For machinery and equipment and construction in progress, we used a combination of the cost and market approaches to estimate our valuation. We applied a 65 percent downward adjustment to book cost based on an analysis of construction documents and historical expenditures to remove non-saleable soft costs such as engineering and installation that would have no secondary market value. Based on discussions with market participants, a salvage value multiplier ranging from 12 percent to 50 percent of the remaining cost basis was applied to arrive at estimated fair value for the assets subject to impairment. For real property, the value of comparable buildings ranged from approximately $30 to $40 per square foot, and the concluded value of the buildings at the Millen facility was approximately $35 per square foot. As a result, the Company recognized a $125,759 impairment of long-lived assets, primarily relating to machinery and equipment and construction in progress. As of September 30, 2017, related to the other asset groups, there were no events or circumstances that would indicate that carrying amounts of long-lived and other noncurrent assets might be impaired given that results for the first nine months of 2017 generally met our expectations from our analysis as of December 31, 2016 and given that our future outlook of cash flows associated with those asset groups has not significantly changed since that date.

Sale of Russian Proppant Business	3. Sale of Russian Proppant Business On July 21, 2017, subsidiaries of the Company Carbo Ceramics (Mauritius) Inc. and Carbo LLC (together, the “Sellers”) entered into a Share Purchase Agreement with Petro Welt Technologies AG and PeWeTe Evolution Limited (together, the “Purchasers”) to sell the Company’s Russian proppant business. The adjusted purchase price is approximately $26,000 for all of the shares of CARBO Ceramics Cyprus Limited held by the Sellers. The transaction received local regulatory approval and closed on September 21, 2017. During the third quarter of 2017, the Company received proceeds of $22,000 related to the sale. The Company expects to receive approximately $4,000 in additional proceeds related to net debt and net working capital purchase price adjustments. The net assets included in the calculation of the loss on the sale were $17,754, including cash and cash equivalents of $846, accounts receivable of $6,047, total inventory of $8,573, net PP&E of $2,763, other net assets of $670, and accrued expenses of $1,145. The Company incurred approximately $1,627 in expenses relating to the sale (of which $468 were paid during the third quarter of 2017, the remainder to be paid during the fourth quarter of 2017). Gain on the sale before consideration of the cumulative translation adjustment was approximately $6,619. However, as a result of the sale, the Company reclassified the foreign currency cumulative translation loss of $33,347 from accumulated other comprehensive loss within shareholders’ equity to net loss which offset the initial gain on the sale. As a result, the Company’s net loss on the sale was approximately $26,728, presented as a separate line item within operating loss on the consolidated statement of operations.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Natural Gas Derivative Instruments	5. Natural Gas Derivative Instruments Natural gas is used to fire the kilns at the Company’s domestic manufacturing plants. In an effort to mitigate potential volatility in the cost of natural gas purchases and reduce exposure to short-term spikes in the price of this commodity, from time to time, the Company enters into contracts to purchase a portion of the anticipated monthly natural gas requirements at specified prices. Contracts are geographic by plant location. As a result of the Company’s significantly reducing production levels and not taking delivery of all of the contracted natural gas quantities, the Company accounts for relevant contracts as derivative instruments. Derivative accounting requires the natural gas contracts to be recognized as either assets or liabilities at fair value with an offsetting entry in earnings. The Company uses the income approach in determining the fair value of these derivative instruments. The model used considers the difference, as of each balance sheet date, between the contracted prices and the New York Mercantile Exchange (“NYMEX”) forward strip price for each contracted period. The estimated cash flows from these contracts are discounted using a discount rate of 8.0%, which reflects the nature of the contracts as well as the timing and risk of estimated cash flows associated with the contracts. The discount rate had an immaterial impact on the fair value of the contracts for the nine months ended September 30, 2017. The last of these natural gas contracts will expire in December 2018. During the three months ended September 30, 2017 and 2016, the Company recognized a $285 gain and $510 loss, respectively, in cost of sales on derivative instruments. During the nine months ended September 30, 2017 and 2016, the Company recognized a $916 loss and a $87 gain, respectively, in cost of sales on derivative instruments. The cumulative present value of these natural gas derivative contracts as of September 30, 2017 are presented as current and long-term liabilities, as applicable, in the Consolidated Balance Sheet. At September 30, 2017, the Company had contracted for delivery a total of 2,430,000 MMBtu of natural gas at an average price of $4.38 per MMBtu through December 31, 2018. Contracts covering 2,280,000 MMBtu are subject to accounting as derivative instruments. Future decreases in the NYMEX forward strip prices will result in additional derivative losses while future increases in the NYMEX forward strip prices will result in derivative gains. Future gains or losses will approximate the change in NYMEX natural gas prices relative to the total quantity of natural gas under contracts now subject to accounting as derivatives. The historical average NYMEX natural gas contract settlement prices for the three months ended September 30, 2017 and 2016 were $3.00 per MMBtu and $2.81 per MMBtu, respectively.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	6. Fair Value Measurements The Company’s derivative instruments are measured at fair value on a recurring basis. U.S. GAAP establishes a fair value hierarchy that has three levels based on the reliability of the inputs used to determine the fair value. These levels include: (1) Level 1, defined as inputs such as unadjusted quoted prices in active markets for identical assets or liabilities; (2) Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and (3) Level 3, defined as unobservable inputs for use when little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s natural gas derivative instruments are included within Level 2 of the fair value hierarchy (see Note 4 herein for additional information on the derivative instruments). The Company’s impaired long-lived assets primarily relating to machinery and equipment and construction in progress at its Millen, Georgia ceramic proppant manufacturing facility are included within the Level 3 fair value hierarchy. The following table sets forth by level within the fair value hierarchy the Company’s assets and liabilities that were accounted for at fair value: Fair value as of September 30, 2017 Level 1 Level 2 Level 3 Total Assets: Impaired long-lived assets — — 18,786 18,786 Liabilities: Derivative instruments — (2,893 ) — (2,893 ) Total fair value $ — $ (2,893 ) $ 18,786 $ 15,893 Fair value as of December 31, 2016 Level 1 Level 2 Level 3 Total Liabilities: Derivative instruments — (3,468 ) — (3,468 ) Total fair value $ — $ (3,468 ) $ — $ (3,468 ) At September 30, 2017, the fair value of the Company’s long-term debt approximated the carrying value.

The amount paid under the Amended and Restated 2014 Omnibus Incentive Plan to any single participant in any calendar year with respect to any cash-based award shall not exceed $5,000. Awards may be granted with respect to a number of shares of the Company’s Common Stock that in the aggregate does not exceed 1,450,000 shares prior to the fifth anniversary of its effective date, plus (i) the number of shares that are forfeited, cancelled or returned, and (ii) the number of shares that are withheld from the participants to satisfy an option exercise price or minimum statutory tax withholding obligations. No more than 100,000 shares may be granted to any single participant in any calendar year. Equity-based awards may be subject to performance-based and/or service-based conditions. With respect to stock options and stock appreciation rights granted, the exercise price shall not be less than the market value of the underlying Common Stock on the date of grant. The maximum term of an option is ten years. Restricted stock awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) proportionately on each of the first three anniversaries of the grant date, but subject to certain limitations, awards may specify other vesting periods. As of September 30, 2017, 753,037 shares were available for issuance under the Amended and Restated 2014 Omnibus Incentive Plan. Although the 2009 CARBO Ceramics Inc. Omnibus Incentive Plan (the “2009 Omnibus Incentive Plan”) has expired, certain nonvested restricted shares granted under that plan remain outstanding in accordance with its terms. A summary of restricted stock activity and related information for the nine months ended September 30, 2017 is presented below: Shares Weighted-Average Grant-Date Fair Value Per Share Nonvested at January 1, 2017 339,140 $ 28.59 Granted 297,685 $ 10.30 Vested (143,762 ) $ 36.33 Forfeited (44,288 ) $ 17.63 Nonvested at September 30, 2017 448,775 $ 15.06 As of September 30, 2017, there was $4,142 of total unrecognized compensation cost related to restricted shares granted under both the expired 2009 Omnibus Incentive Plan and the Amended and Restated 2014 Omnibus Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.8 years. The total fair value of shares vested during the nine months ended September 30, 2017 was $2,007. The Company made market-based cash awards to certain executives of the Company pursuant to the Amended and Restated 2014 Omnibus Incentive Plan. As of September 30, 2017, the total target award outstanding was $2,822. The payout of awards can range from 0% to 200% based on the Company’s Relative Total Shareholder Return calculated over a three year period beginning January 1 of the year each grant was made. The Company also granted phantom stock and cash-settled restricted stock units (collectively discussed as “phantom stock”) to certain key employees pursuant to the Amended and Restated 2014 Omnibus Incentive Plan. The units subject to a phantom stock award vest and cease to be forfeitable in equal annual installments over a three-year period. Participants awarded units of phantom stock are entitled to a lump sum cash payment equal to the fair market value of a share of Common Stock on the vesting date. In no event will Common Stock of the Company be issued with regard to outstanding phantom stock awards. As of September 30, 2017, there were 163,215 units of phantom stock granted under the Amended and Restated 2014 Omnibus Incentive Plan, of which 4,189 have vested and 12,950 have been forfeited. As of September 30, 2017, nonvested units of phantom stock under the Amended and Restated 2014 Omnibus Incentive Plan had a total value of $1,261, a portion of which is accrued as a liability within Accrued Payroll and Benefits. Compensation expense for these units of phantom stock will be recognized over the three-year vesting period. The amount of compensation expense recognized each period will be based on the fair value of the Company’s common stock at the end of each period.

Long-Term Debt and Notes Payabl

Debt Disclosure [Abstract]
Long-Term Debt and Notes Payable	8. Long-Term Debt and Notes Payable On March 2, 2017, the Company entered into an Amended and Restated Credit Agreement (the “New Credit Agreement”) with Wilks Brothers, LLC (“Wilks”) to replace its current term loan with Wells Fargo Bank, National Association (“Wells Fargo”) and provide the Company with additional liquidity for a longer term. The New Credit Agreement is a $65,000 facility maturing on December 31, 2022, that consists of a $52,651 term loan that was made at closing to pay off Wells Fargo and an additional term loan of $12,349 that was made in a single advance to the Company in July 2017 after the Company satisfied certain post-closing conditions. The $52,651 term loan was a non-cash transaction to the Company as Wilks directly paid Wells Fargo and assumed the New Credit Agreement. The Company’s obligations bear interest at 9.00% and are guaranteed by its two domestic operating subsidiaries. No principal repayments are required until maturity (except in unusual circumstances), and there are no financial covenants. In lieu of making cash interest payments, the Company has the option during the first two years of the loan to make interest payments as payment-in-kind, or PIK, by applying an 11.00% rate to the interest payment due (instead of the 9.00% cash interest rate) and capitalizing the resulting amount to the outstanding principal balance of the loan. The Company is required to provide Wilks 30 day notice of its intent to exercise this option for an interest payment. The Company does not anticipate utilizing this option and has therefore accrued interest expense using the 9.00% cash interest rate. The loan cannot be prepaid during the first three years without making the lenders whole for interest that would have been payable over the entire remaining term of the loan. The Company’s obligations under the New Credit Agreement are secured by: (i) a pledge of all accounts receivable and inventory, (ii) cash in certain accounts, (iii) domestic distribution assets residing on owned real property, (iv) the Company’s Marshfield, Wisconsin and Toomsboro, Georgia plant facilities and equipment, and (v) certain real property interests in mines and minerals. Other liens previously in favor of Wells Fargo were released. As of September 30, 2017, the Company’s outstanding debt under its New Credit Agreement was $65,000. During the nine months ended September 30, 2017, the Company expensed $455 of debt issuance costs relating to the previous Wells Fargo Amended Credit Agreement. As of September 30, 2017, the Company had $896 of unamortized debt issuance costs relating to the New Credit Agreement that are presented as a direct reduction from the carrying amount of the long-term debt obligation. The Company had $9,230 and $11,980 in standby letters of credit issued through Wells Fargo as of September 30, 2017 and December 31, 2016, respectively, primarily as collateral relating to our natural gas commitments and railcar leases. As of December 31, 2016, the Company’s outstanding debt under its previous Wells Fargo Amended Credit Agreement was $55,901, of which $13,000 was classified as current and $42,901 was classified as long-term. As of December 31, 2016, the Company had $497 of debt issuance costs that are presented as a direct reduction from the carrying amount of the long-term debt obligation. For the year ended December 31, 2016, the weighted average interest rate was 6.447% based on LIBOR-based rate borrowings. On March 2, 2017, in connection with entry into the New Credit Agreement, the Company issued a Warrant (the “Warrant”) to Wilks. Subject to the terms of the Warrant, the Warrant entitles the holder thereof to purchase up to 523,022 shares of the Common Stock, at an exercise price of $14.91 per share, payable in cash. The Warrant expires on December 31, 2022. Based on a Schedule 13D filing with the SEC, as of May 22, 2017, Wilks owned 10.4% of the Company’s outstanding common stock, and should Wilks fully exercise the Warrant to purchase an additional 523,022 shares, it would hold 12.3% of the Company’s outstanding common stock. The Company allocated the proceeds received of $52,651 to each of these two instruments based on their relative fair values. Accordingly, the Company recorded long-term debt of $48,780 and warrants of $3,871 at inception. The amount associated with the Warrant was recorded as an increase to additional paid-in capital. The original issue discount of the long-term debt will be amortized using the effective interest method over the term of the loan. As of September 30, 2017, the unamortized original issue discount was $3,578. In May 2016, the Company received proceeds of $25,000 from the issuance of separate unsecured Promissory Notes (the “Notes”) to two of the Company’s Directors. Each Note matures on April 1, 2019 and bears interest at 7.00%. On March 2, 2017, in connection with the New Credit Agreement, the Notes were amended to provide for payment-in-kind, or PIK, interest payments at 8.00% until the lenders under the New Credit Agreement receive two consecutive semi-annual cash interest payments. On April 1, 2017, the Company made a $997 interest payment as PIK, and capitalized the resulting amount to the outstanding principal balance. As of September 30, 2017, the outstanding principal balance of the Notes was $25,997. On October 1, 2017, the Company made a $1,043 interest payment as PIK, and capitalized the resulting amount to the outstanding principal balance. As of November 9, 2017, the outstanding principal balance of the Notes was $27,040. Interest cost for the nine months ended September 30, 2017 and 2016 was $5,966 and $4,319, respectively, of which $0 and $80 was capitalized into the cost of property, plant and equipment in the nine months ended September 30, 2017 and 2016, respectively. Interest cost primarily includes interest expense relating to our debts as well as amortization and the write-off of debt issuance costs and amortization of the original issue discount associated with the New Credit Agreement and Warrant. In June 2017, the Company entered into an agreement with a financing company to finance certain insurance premiums in the amount of $1,246. Payments are due monthly through April 1, 2018 with an effective interest rate of 0.91%. The liability is included in Notes Payable within Current Liabilities on the Consolidated Balance Sheet. As of September 30, 2017, the outstanding balance was $874.

Segment Reporting [Abstract]
Segment Information	11. Segment Information The Company has two operating segments: 1) oilfield technologies and services and 2) environmental products and services. Discrete financial information is available for each operating segment. Management of each operating segment reports to our Chief Executive Officer, the Company’s chief operating decision maker, who regularly evaluates income before income taxes as the measure to evaluate segment performance and to allocate resources. The accounting policies of each segment are the same as those described in the summary of significant accounting policies in Note 1 of the consolidated financial statements included in the annual report on Form 10-K for the year ended December 31, 2016. The Company’s oilfield technologies and services segment manufactures and sells technology ceramic, base ceramic, and frac sand proppants for use primarily in the hydraulic fracturing of natural gas and oil wells. All of the Company’s ceramic proppant products have similar production processes and economic characteristics and are marketed predominantly to pressure pumping companies that perform hydraulic fracturing for major oil and gas companies. The Company’s manufacturing facilities also produce ceramic pellets for use in various industrial technology applications, including but not limited to casting and milling. This segment also promotes increased production and Estimated Ultimate Recovery (“EUR”) of oil and natural gas by providing industry leading technology to Design, Build, and Optimize the Frac TM ® Our environmental products and services segment is intended to protect operators’ assets, minimize environmental risks, and lower lease operating expense (“LOE”). AGPI, a wholly-owned subsidiary of ours, provides spill prevention, containment and countermeasure systems for the oil and gas industry. AGPI uses proprietary technology designed to enable its clients to extend the life of their storage assets, reduce the potential for hydrocarbon spills and provide containment of stored materials. Summarized financial information for the Company’s operating segments for the three and nine months ended September 30, 2017 and 2016 is shown in the following tables. As there has been a material change in total assets since December 31, 2016, segment assets are also presented as of September 30, 2017. Intersegment sales are not material.

Accounting Policies [Abstract]
Deferred Taxes - Valuation Allowance	Deferred Taxes – Valuation Allowance Accounting Standards Codification (“ASC”) Topic 740, Income Taxes, provides the carrying value of deferred tax assets should be reduced by the amount not expected to be realized. A company should reduce deferred tax assets by a valuation allowance if, based on the weight of all available evidence, it is not more likely than not that some portion or all of the deferred tax assets will be realized. The valuation allowance should be sufficient to reduce the deferred tax asset to the amount that is more likely than not to be realized. ASC 740 requires all available evidence, both positive and negative, be considered to determine whether a valuation allowance for deferred tax assets is needed in the financial statements. Additionally there can be statutory limitations and losses also assessed on the deferred tax assets should certain conditions arise.
Restricted Cash	Restricted Cash As a result of the repayment of the Wells Fargo term loan, combined with the continued use of letters of credit and corporate cards with Wells Fargo (see Note 8), a portion of the Company’s cash balance is now restricted to its use in order to provide collateral to Wells Fargo. As of September 30, 2017 and December 31, 2016, restricted cash was $10,216 and $0, respectively.
Lower of Cost or Market Adjustments	Lower of Cost or Market Adjustments As of September 30, 2017, the Company reviewed the carrying values of all inventories and concluded that no adjustments were warranted for finished goods and raw materials intended for use in the Company’s manufacturing process. As of September 30, 2016, the Company reviewed the carrying values of all inventories and concluded that certain sand inventories were impacted by changes in market conditions. Consequently, during the nine-month period ended September 30, 2016, the Company recognized a $115 loss in cost of sales to adjust the carrying value to the lower market prices on certain sand inventories.
Manufacturing Production Levels Below Normal Capacity	Manufacturing Production Levels Below Normal Capacity As a result of the Company substantially reducing manufacturing production levels, including by idling certain facilities, certain production costs have been expensed instead of being capitalized into inventory. The Company expenses fixed production overhead amounts in excess of amounts that would have been allocated to each unit of production at normal production levels. For the three months ended September 30, 2017 and 2016, the Company expensed $10,890 and $12,845, respectively, in production costs. For the nine months ended September 30, 2017 and 2016, the Company expensed $32,899 and $36,067, respectively, in production costs.
Long-lived and other noncurrent assets impairment	Long-lived and other noncurrent assets impairment As noted, throughout 2017 and 2016, the Company has temporarily idled production at various manufacturing facilities. The Company does not assess temporarily idled assets for impairment unless events or circumstances indicate that the carrying amounts of those assets may not be recoverable. Short-term stoppages of production for less than one year do not generally significantly impact the long-term expected cash flows of the idled facility. At December 31, 2016, as a result of the continued severity of the market downturn, the Company identified indicators of impairments related to each of its domestic manufacturing plant asset groups. The Company completed undiscounted cash flow analyses on that date and determined no impairment charge was necessary at that time. As of September 30, 2017, the Company concluded that the Company’s Toomsboro and Millen, Georgia facilities should no longer be evaluated together as a group of assets because the facilities are no longer interchangeable and will not manufacture like products. As a result of the sustained and long-term shift away from base ceramic proppant to less expensive frac sand, the Company has made a strategic decision to focus on growing technology, industrial and mineral processing revenue streams. Our Toomsboro, Georgia plant is being repurposed to produce technology and industrial products, as well as for use in toll processing of minerals. Our Millen, Georgia facility is currently only able to produce base ceramic proppants, but given our current long-term outlook on base ceramic proppant demand, we do not expect to utilize this plant to produce base ceramic proppant. We are currently evaluating opportunities to monetize our assets at our Millen facility. As a result, we evaluated the Toomsboro and Millen, Georgia plants separately for indicators of impairment during the third quarter of 2017. Given the change in the asset groupings of the two facilities and lack of estimated future cash flows associated with the base ceramic production at the Millen facility, the Company identified indicators of impairment at the Millen, Georgia facility as of September 30, 2017. The Company determined that the projected cash flows attributable to our Millen, Georgia facility did not exceed the carrying value of the assets; therefore the Company concluded there was an impairment at that facility. The Company engaged the services of a third party consulting firm to assist with the determination of the fair market value of the related assets and concluded that the assets were impaired. The key assumptions and inputs impacting the fair value include third party market data with respect to the property and equipment at our Millen facility as well as at comparable facilities. For machinery and equipment and construction in progress, we used a combination of the cost and market approaches to estimate our valuation. We applied a 65 percent downward adjustment to book cost based on an analysis of construction documents and historical expenditures to remove non-saleable soft costs such as engineering and installation that would have no secondary market value. Based on discussions with market participants, a salvage value multiplier ranging from 12 percent to 50 percent of the remaining cost basis was applied to arrive at estimated fair value for the assets subject to impairment. For real property, the value of comparable buildings ranged from approximately $30 to $40 per square foot, and the concluded value of the buildings at the Millen facility was approximately $35 per square foot. As a result, the Company recognized a $125,759 impairment of long-lived assets, primarily relating to machinery and equipment and construction in progress. As of September 30, 2017, related to the other asset groups, there were no events or circumstances that would indicate that carrying amounts of long-lived and other noncurrent assets might be impaired given that results for the first nine months of 2017 generally met our expectations from our analysis as of December 31, 2016 and given that our future outlook of cash flows associated with those asset groups has not significantly changed since that date.
