CORRESP

Pursuant to discussions with the staff of the Division of Corporation Finance (the “Staff”) of the Securities and Exchange Commission (the “Commission”), Solaris Oilfield Infrastructure, Inc. (the “Company,” “we,” “us” or “our”) hereby confidentially submits its currently expected offering terms of the initial public offering (the “Offering”) of Class A common stock, par value $0.01 per share (the “Common Stock”), including the bona fide price range pursuant to Item 503(b)(3) of Regulation S-K, the number of shares of Common Stock to be offered, the estimated net proceeds the Company expects to receive from the Offering and the total number of shares of Common Stock to be outstanding after the Offering. The Company expects that these pricing terms will be included in a future amendment to the Registration Statement on Form S-1, File No. 333-216721 (the “Registration Statement”).

The Offering terms are a bona fide estimate of the range of the minimum and maximum offering price and the maximum number of securities to be offered as of April 21, 2017. Should the bona fide estimates of these terms change, the figures presented in future amendments to the Registration Statement may increase or decrease.

The Company proposes to price the Offering with a bona fide price range of $15.00 to $18.00 per share of Common Stock, with a midpoint of $16.50 per share. In the Offering, the Company proposes to sell 10,600,000 shares of Common Stock. The Company proposes to grant the underwriters a 30-day option to purchase up to an aggregate of additional 1,590,000 shares of Common Stock held by the Company to cover over-allotments, if any. As discussed with members of the Staff, this range is initially being provided for your consideration by correspondence due to the Company’s and the underwriters’ concern regarding providing such information in advance of the launch of the Offering given recent market volatility, as well as our desire to provide all information necessary for the Staff to complete its review on a timely basis.

Additionally, the Company is enclosing as Exhibit A its proposed marked copy of those pages of the Registration Statement that will be incorporated into a future amendment to the Registration Statement. The Company seeks confirmation from the Staff that it may launch its Offering with the price range specified herein and include such price range in a future filing of the Registration Statement.

Please direct any questions that you have with respect to the foregoing to Douglas E. McWilliams of Vinson & Elkins L.L.P. at (713) 758-3613 or Julian J. Seiguer of the same firm at (713) 758-2790.


Very truly yours,
