Summary of Significant Accounting Policies (Policies)	Mar. 31, 2019
Accounting Policies [Abstract]
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 Securities and Exchange Commission for quarterly reports on Form 10-Q and therefore do not include all the information and notes required by accounting principles generally sccepted in the United States (“U.S. 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, 2018 was derived from the audited consolidated financial statements as of and for the year ended December 31, 2018. These interim statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2018.
Segment Information	Segment Information Reportable operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision maker is the Chief Executive Officer. The Company and the Chief Executive Officer view the Company’s operations and manage its business, including the recently acquired logistics assets and wellsite proppant storage solutions business, as one reportable operating segment.
Reclassification	Certain 2018 balance sheet items have been reclassified to conform to the current financial statement presentation. These reclassifications have no effect on previously reported net income.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), and related amendments, which replaces the existing guidance in ASC 840, Leases. ASU 2016-02 requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets. The new lease standard does not substantially change lessor accounting. The new standard is effective for interim and annual reporting periods beginning after December 15, 2018. The Company adopted ASU 2016-02 and its related updates using the optional transition practical expedients, which allow the Company to use the existing lease population, classification and determination of initial direct costs when calculating the lease liability and right-of-use asset balances. The Company also used the optional transition method, which allows the Company to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings. There was no adjustment made to the opening balance of retained earnings. The Company has implemented new accounting policies and software to facilitate the recording and reporting of lease transactions and balances. The Company recorded initial operating right-of-use assets of $35,939 and related lease liabilities of $36,484 on its consolidated balance sheet on January 1, 2019. New disclosures are included in Note 9 to these interim financial statements. Not yet adopted In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which modifies disclosure requirements for fair value measurements by removing the disclosure of the valuation process for Level 3 fair value measurements, among other disclosure modifications. The guidance is effective for the Company beginning after December 15, 2019, although early adoption is permitted. Companies are permitted to remove or modify disclosures upon issuance while delaying adoption of the additional disclosures. The Company is currently evaluating the effects of ASU 2018-13 on its consolidated financial statements. Changes to Accounting Policies Leases - Lessee The Company uses leases primarily to procure certain office space, railcars and heavy equipment as part of its operations. The majority of its lease payments are fixed and determinable with certain of its lease payments containing immaterial variable payments based on the number of hours the equipment is used. Certain of its leases have options that allow for renewal at market rates, purchase at fair market value or termination of the lease. The Company must determine that it is reasonably certain that a lease option will be exercised for such an option to be included in the right-of-use asset or lease liability. The Company is not reasonably certain that any of its lease options will be exercised and, as such, has not included those options in its right-of-use assets or lease liabilities. Certain of its equipment leases contain residual value guarantees which guarantee various parts of heavy equipment will have a remaining life when the equipment is returned to the lessor. It is possible that the Company could owe additional amounts to the lessor upon return of equipment. There are no restrictions or covenants imposed by any of the Company's leases. The Company evaluates contracts during the negotiation process and when they are executed to determine the existence of leases. A contract contains a lease when it conveys the right to use property, plant or equipment for a stated period of time in exchange for consideration. Leases with an initial term of twelve months or less are not recorded on the balance sheet. The Company recognizes lease expense on a straight-line basis over the term of the lease. The Company evaluates the classification of its leases at the commencement date and includes both lease and non-lease components in its calculation of consideration in the contract for all classes of operating leases. The Company applies a single discount rate to all operating leases. The Company determined its incremental borrowing rate based on an average of collateralized borrowing rates offered by various lenders. The Company considered the nature of the assets and the life of the leases and determined that there is no significant difference in the incremental borrowing rate. See Note 9 — Leases for additional disclosures regarding the Company’s leasing activity. Leases - Lessor The Company manufactures equipment and offers for lease its wellsite proppant storage solutions. The Company negotiates the terms of its leases on a case-by-case basis. There are no significant options that are reasonably certain to be exercised, residual value guarantees, restrictions or covenants in its lease contracts and have, therefore, not been included in its accounting for the leases. There are currently no contracts in place that meet the definition of a lease.
