Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Business	Organization and Nature of Business & Market Update Organization and Nature of Business The Company was incorporated in July 2011 and is headquartered in The Woodlands, Texas. The Company is a fully integrated frac sand supply and services company, offering complete mine to wellsite proppant supply, logistics and storage solutions. The Company is engaged in the excavation, processing and sale of sand, or proppant, for use in hydraulic fracturing operations for the oil and natural gas industry and offers proppant logistics and wellsite storage solutions through its SmartSystems TM products and services. The Company commenced mining operations at its Oakdale, Wisconsin facility in July 2012. Through multiple expansions at Oakdale and the acquisition in September 2020 of the Utica, Illinois mine and processing facilities, the Company has current annual processing capacity of approximately 7.1 million tons. The Company provides complete logistics solutions through its frac sand facilities with access to three Class I rail lines and its in-basin unit train capable transloading terminal in Van Hook, North Dakota to service the Bakken Formation in the Williston Basin. In September 2021, the Company acquired the rights to construct and operate another transloading terminal in Waynesburg, Pennsylvania to service the Appalachian Basin, including the Marcellus and Utica Formations. The Company expects this terminal to become operational in the fourth quarter of 2021. These logistics solutions enable the Company to cost-effectively deliver products to its customers anywhere in the United States. The Company provides proppant storage and management solutions through its SmartSystems products and services under which it offers various solutions that create efficiencies, flexibility, enhanced safety and reliability for customers by providing the capability to unload, store and deliver proppant at the wellsite, as well as the ability to rapidly set up, takedown and transport the entire system. The SmartDepot TM silo system includes passive and active dust suppression technology, along with the capability of a gravity-fed operation. The Company has developed a new transload technology, the self-contained SmartPath TM

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The information presented below supplements the complete description of our significant accounting policies disclosed in our 2020 Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 3, 2021. Basis of Presentation and Consolidation The accompanying unaudited quarterly condensed consolidated financial statements (“interim statements”) of the Company are presented in accordance with the rules and regulations of the SEC for quarterly reports on Form 10-Q and therefore do not include all the information and notes required by GAAP. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these interim statements have been included. All adjustments are of a normal recurring nature. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. The consolidated balance sheet as of December 31, 2020 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2020. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2020. Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates used in the preparation of these financial statements include, but are not limited to: the sand reserves and their impact on calculating the depletion expense under the units-of-production method; the depreciation and amortization associated with property, plant and equipment and definite-lived intangible assets, impairment considerations of assets (including impairment of identified intangible assets and other long-lived assets); estimated cost of future asset retirement obligations; fair value of acquired assets and assume liabilities; stock-based compensation; recoverability of deferred tax assets; inventory reserve; collectability of receivables; and certain liabilities. Actual results could differ materially from management’s best estimates as additional information or actual results become available in the future. The decreased demand related to the coronavirus (“COVID-19”) pandemic caused dramatic swings in oil prices and significant volatility in the oilfield service sector since March 2020. The Company is currently unable to estimate the impact of these events on its future financial position and results of operations. Therefore, the Company can give no assurances that these events will not have a material adverse effect on its financial position or results of operations. Employee Retention Credit The Company qualified for federal government assistance through employee retention credit provisions of the Consolidated Appropriations Act of 2021. During the three and nine months ended September 30, 2021, the Company recorded $1,674 and $5,026, respectively, of employee retention credits in other income on its consolidated income statements and included in prepaid expenses and other current assets on the consolidated balance sheet as of September 30, 2021. The calculation of the credit is based on employees continued employment and represents a portion of the wages paid to them. For income tax purposes, the credit will result in decreased expense related to the wages it offsets in the period received. Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which modifies how companies recognize expected credit losses on financial instruments and other commitments to extend credit held by an entity at each reporting date. Existing GAAP requires an “incurred loss” methodology whereby companies are prohibited from recording an expected loss until it is probable that the loss has been incurred. ASU 2016-13 requires companies to use a methodology that reflects current expected credit losses (“CECL”) and requires consideration of a broad range of reasonable and supportable information to record and report credit loss estimates, even when the CECL is remote. Companies will be required to record the allowance for credit losses and deduct that amount from the basis of the asset and a related expense will be recognized in selling, general and administrative expenses on the income statement, similar to bad debt expense under existing GAAP. There is much latitude given to entities in determining the methodology for calculating the CECL. The guidance is effective for the Company for financial statement periods beginning after December 15, 2022, although early adoption is permitted. While the Company is still in the process of evaluating the effects of ASU 2016-13 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect, if any will be an allowance recorded against its accounts and unbilled receivables on its balance sheet and related expense on its income statement. The Company cannot determine the financial impact on its consolidated financial statements upon adoption as its accounts and unbilled receivables balances are affected by ongoing transactions with customers.

Business Combination Disclosure	Business Combination Eagle Proppants Holdings On September 18, 2020, the Company entered into an Equity Purchase and Sale Agreement (the “Purchase Agreement”) with Eagle Materials Inc., a Delaware corporation (“Eagle”), pursuant to which the Company acquired all of the issued and outstanding interests in Eagle Oil and Gas Proppants Holdings LLC, a Delaware limited liability company and wholly-owned subsidiary of Eagle (“Eagle Proppants Holdings”), from Eagle for aggregate non-cash consideration of approximately $2,080. In satisfaction of the purchase price, the Company issued to Eagle 1,504 shares of its common stock; the Company issued an additional 14 shares of its common stock in January 2021 as settlement of the net working capital adjustment. The number of shares issued was determined by the weighted average trading price of the Company’s common stock over the twenty days preceding the date of the Purchase Agreement. The primary assets of Eagle Proppants Holdings and its subsidiaries include a frac sand mine and related processing facility in Utica, Illinois and a transload facility in nearby Peru, Illinois. The Utica facility has approximately 1.6 million tons of annual processing capacity and has access to the BNSF rail line through the Peru, Illinois transload facility. The table below presents the calculation of the total purchase consideration: Base price consideration $ 2,000 20-day volume weighted average price of Smart Sand stock $ 1.33 Shares issued 1,504 Closing share price on September 18, 2020 $ 1.37 Total equity issued $ 2,060 Net working capital adjustment $ 20 Total purchase consideration $ 2,080 The Company’s final allocation of the purchase price in connection with the acquisition was calculated as follows: Fair Value Assets Acquired Cash $ 309 Accounts receivable 75 Inventory 2,459 Prepaid expenses and other current assets 124 Property, plant and equipment 60,310 Right-of-use assets 9,603 Total assets acquired 72,880 Liabilities Assumed Accounts payable 16 Accrued expenses and other liabilities 2,008 Asset retirement obligations 8,424 Operating lease liabilities 9,603 Deferred income taxes 11,149 Total liabilities assumed 31,200 Estimated fair value of net assets acquired $ 41,680 The estimated aggregate fair value of the net assets acquired was $41,680, which exceeded the total consideration and results in a bargain purchase gain of $39,600 on the acquisition date, which is included in net income for the year ended December 31, 2020. The Company believes that the seller wanted to exit the business relatively quickly and that there were a limited number of potential buyers due to the downturn in the market, which resulted in the bargain purchase gain. The Company determined the fair values of the acquired assets and assumed liabilities based on the highest and best use of such assets as required by GAAP. Cash, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other liabilities were based on underlying assets and liabilities whose carrying value approximates fair value. The Company acquired $2,050 of contractual receivables; however, it does not expect to collect on $1,975 of such contractual receivables as these customers are in bankruptcy proceedings. The fair value of inventory was determined using market prices the Company expected to receive for the inventory when it is sold. Operating leases were considered to be at

In satisfaction of the purchase price, the Company issued to Eagle 1,504 shares of its common stock; the Company issued an additional 14 shares of its common stock in January 2021 as settlement of the net working capital adjustment. The number of shares issued was determined by the weighted average trading price of the Company’s common stock over the twenty days preceding the date of the Purchase Agreement. The primary assets of Eagle Proppants Holdings and its subsidiaries include a frac sand mine and related processing facility in Utica, Illinois and a transload facility in nearby Peru, Illinois. The Utica facility has approximately 1.6 million tons of annual processing capacity and has access to the BNSF rail line through the Peru, Illinois transload facility.

The Company believes that the seller wanted to exit the business relatively quickly and that there were a limited number of potential buyers due to the downturn in the market, which resulted in the bargain purchase gain. The Company determined the fair values of the acquired assets and assumed liabilities based on the highest and best use of such assets as required by GAAP. Cash, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other liabilities were based on underlying assets and liabilities whose carrying value approximates fair value. The Company acquired $2,050 of contractual receivables; however, it does not expect to collect on $1,975 of such contractual receivables as these customers are in bankruptcy proceedings.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per ShareBasic net (loss) income per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, excluding the dilutive effects of restricted stock. Diluted net (loss) income per share of common stock is computed by dividing the net (loss) income attributable to common stockholders by the sum of the weighted-average number of shares of common stock outstanding during the period plus the potential dilutive effects of restricted stock outstanding during the period calculated in accordance with the treasury stock method, although restricted stock is excluded if their effect is anti-dilutive. Because the impact of these items is anti-dilutive during periods of net loss, there was no difference between basic and diluted net loss per share of common stock for the three and nine months ended September 30, 2021. Because their effect would be anti-dilutive, 2,237 shares of common stock underlying equity-based awards were excluded from the calculation of diluted earnings per share for both three and nine months ended September 30, 2020. There is no reconciliation between weighted average common shares outstanding and diluted weighted average shares of common stock outstanding for any period presented.

The Company and defendant also entered into a two year Right of First Refusal Agreement covering all purchases of Northern White frac sand by defendant and its affiliates in the continental United States from January 1, 2022 through December 31, 2023. The Company recorded $19,592 as non-cash bad debt expense, which is the difference between the $54,592 accounts receivable balance that was under litigation and the cash received under the Settlement Agreement. Bonds The Company has performance bonds with various public and private entities regarding reclamation, permitting and maintenance of public roadways. Total aggregate principal amount of performance bonds outstanding as of September 30, 2021 was $9,478.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited quarterly condensed consolidated financial statements (“interim statements”) of the Company are presented in accordance with the rules and regulations of the SEC for quarterly reports on Form 10-Q and therefore do not include all the information and notes required by GAAP. In the opinion of management, all adjustments and disclosures necessary for a fair presentation of these interim statements have been included. All adjustments are of a normal recurring nature. The results reported in these interim statements are not necessarily indicative of the results that may be reported for the entire year. The consolidated balance sheet as of December 31, 2020 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2020. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2020.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates used in the preparation of these financial statements include, but are not limited to: the sand reserves and their impact on calculating the depletion expense under the units-of-production method; the depreciation and amortization associated with property, plant and equipment and definite-lived intangible assets, impairment considerations of assets (including impairment of
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which modifies how companies recognize expected credit losses on financial instruments and other commitments to extend credit held by an entity at each reporting date. Existing GAAP requires an “incurred loss” methodology whereby companies are prohibited from recording an expected loss until it is probable that the loss has been incurred. ASU 2016-13 requires companies to use a methodology that reflects current expected credit losses (“CECL”) and requires consideration of a broad range of reasonable and supportable information to record and report credit loss estimates, even when the CECL is remote. Companies will be required to record the allowance for credit losses and deduct that amount from the basis of the asset and a related expense will be recognized in selling, general and administrative expenses on the income statement, similar to bad debt expense under existing GAAP. There is much latitude given to entities in determining the methodology for calculating the CECL. The guidance is effective for the Company for financial statement periods beginning after December 15, 2022, although early adoption is permitted. While the Company is still in the process of evaluating the effects of ASU 2016-13 and its related updates on the consolidated financial statements, at the time of adoption, it believes the primary effect, if any will be an allowance recorded against its accounts and unbilled receivables on its balance sheet and related expense on its income statement. The Company cannot determine the financial impact on its consolidated financial statements upon adoption as its accounts and unbilled receivables balances are affected by ongoing transactions with customers.
