 Exhibit 10.18 

MASTER DRILLING AGREEMENT 

THIS MASTER DRILLING AGREEMENT (this “Agreement”) is made and entered into to be effective as of the 1st day of January 2013, by and
between DIAMONDBACK E&P LLC (“Operator”) and BISON DRILLING AND FIELD SERVICES LLC (“Contractor”). 

RECITALS: 
 A.
Contractor is the owner of certain drilling rigs located in the Permian Basin (referred to as the “Rigs”); and 
 B. Subject to
the limitations provided in paragraph 4 below, Operator desires to use the Rigs in connection with Contractor’s exploration for oil and gas in the Permian Basin and as provided herein, and Contractor desires to provide Rigs for such purposes.

 NOW, THEREFORE, in consideration of the premises, covenants and conditions herein, and other valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, Operator and Contractor hereby agree as follows: 
 1. Form of Drilling Agreement. The
terms and conditions pursuant to which each of the Rigs shall be used and operated shall be as set forth in the Drilling Bid Proposal and Daywork Drilling Contract (i) attached hereto as Exhibit “A” for a vertical well and
(ii) attached hereto as Exhibit “B” for a horizontal well (in either event, the “Drilling Contract”). A separate Drilling Contract shall be deemed to apply to each well drilled under this Agreement. 

2. Term. This Agreement may be terminated at the option of either party by giving the other party written notice to that effect, which
termination shall become effective thirty (30) calendar days after the giving of such written notice; however, neither party hereto shall, by the termination of this Agreement, be relieved of its respective obligations arising from or incident
to a Drilling Contract then in effect hereunder and not yet fully performed at or prior to the time the termination of this Agreement becomes effective. 

3. Purchase of Services. This Agreement and the applicable Drilling Contract shall control and govern any and all use of the Rigs by
Contractor for Operator (the “Drilling Services”). Drilling Services will be as requested by Operator to Contractor and will be defined by separate orders (either verbal or written) from Operator to Contractor (each an “Order”).
This Agreement and the applicable Drilling Contract shall be deemed to be incorporated in full in every Order effective upon the giving of such Order if verbal or the receipt of such Order by Contractor if written. Operator shall endeavor to provide
written confirmation of any oral Orders within ten (10) working days after same are given, but the failure to do so shall not invalidate the Order or the obligations of the parties arising hereunder by reason of such Order. 

4. Obligation to Request/Accept Work. Except as otherwise provided in this paragraph 4, Operator shall be obligated to order from
Contractor Drilling Services required by Operator within the Permian Basin, and Contractor shall be obligated to provide such Drilling Services to Operator; provided, the requirement of the preceding sentence shall apply only to the extent of two
Rigs for vertical wells; provided further, that Operator may require from time-to-time, in its sole discretion, that one of the Rigs be for horizontal wells. The provision of Drilling 

 
Services in addition to the foregoing limitation is voluntary with both Operator and Contractor. For avoidance of doubt, this Agreement does not obligate Operator to issue any Order to Contractor
for Drilling Services and it does not obligate Contractor to accept an Order from Operator for Drilling Services for a Rig if two Rigs are then obligated to perform Drilling Services hereunder and such Drilling Services have not been completed.
Further, the parties shall be relieved of the obligation as to the use of a Rig during the period of time when total loss, destruction or breakdown causes the Rig to be unavailable for commencement of operations under a Drilling Contract. 

5. Notices. Except as provided otherwise in paragraph 3 above, all notices or other communications hereunder (and the term
“notices” as used in this paragraph includes communications) shall be in writing and may be effected by (i) personal delivery, (ii) registered or certified mail, postage prepaid with return receipt requested, (iii) sent and
delivered by a nationally recognized overnight delivery service, or (iv) by email with written confirmation promptly thereafter in accordance with clauses (i), (ii) or (iii) or by return email. Mailed notices shall be addressed to the
parties at the addresses appearing below, but each party may change its address by written notice to the other party in accordance with this Agreement. Notices delivered personally shall be deemed communicated as of actual receipt; mailed notices
shall be deemed communicated upon receipt, refusal or as of the first attempted date of delivery if unclaimed; and email notices shall be deemed communicated as of the date of actual receipt; provided, emails not received between the hours of 8:30
a.m. and 5:00 p.m. local time on a date which is not a Saturday, Sunday, or federal or state holiday (business day), shall be deemed received at 8:30 a.m. on the next business day.

“Principal”) together with all accrued and unpaid interest thereon, as hereinafter provided (the “Note”). 
 1.
Interest. The Principal of this promissory note (this “Note”) shall bear interest (“Interest”) at a rate equal to the lesser of (x) the prime rate of interest announced from time to time by Citibank, N.A. plus two and
one half percent (2.5%) per annum, or (y) the maximum rate of interest permitted by applicable law, from the date advanced and shall continue to accrue on a daily basis on the unpaid Principal until paid in full; provided that, if any
Event of Default (as defined below) shall occur, Interest shall instead accrue on the unpaid Principal, from and after the occurrence of the relevant Event of Default (as defined below), at the lesser of (x) the rate of sixteen percent
(16%) per annum, or (y) the maximum rate of interest permitted by applicable law. All Interest on this Note shall be computed on the actual number of days elapsed over a 360 day year.

violation of this paragraph, the Holder shall pay such excess funds over to the holders of the Pari Passu Notes or purchase Pari Passu Notes or interests therein from the holders thereof in order to cause the excess payment to be shared among the

4. Subordination. 
 (a)
The indebtedness evidenced by the Note is hereby expressly subordinated, to the extent and in the manner hereinafter set forth, in right of payment to the prior payment in full of all the Company’s Senior Indebtedness. If an Insolvency (as
defined below) has occurred and is continuing, the Company may not make any payment in respect of the Principal of this Note until the Senior Indebtedness has been paid in full. In the event of a distribution of the assets of the Company in
connection with an Insolvency, such distribution shall be applied to the Senior Indebtedness until the Senior Indebtedness has been paid in full, and thereafter to the payment of the Principal of this Note and the principal of the Pari Passu Notes.

 (b) As used in this Note, the term “Senior Indebtedness” shall mean, unless expressly subordinated to or made on a parity with
the amounts due under this Note, (i) the principal of (and premium, if any), unpaid interest on and amounts reimbursable, fees, expenses, costs of enforcement and other amounts due in connection with that Business Note, dated January 31,
2013 with Citizens State Bank of La Crosse in the amount of $3,000,000 and any extension, renewal, amendment, modification or refinancing of the indebtedness thereunder if the principal amount of such indebtedness after giving effect thereto does
not exceed maximum principal amount of such indebtedness as in effect immediately prior thereto and (ii) the principal of (and premium, if any), unpaid interest on and amounts reimbursable, fees, expenses, costs of enforcement and other amounts
due in connection with that contemplated five year term auto loan with Citizens State Bank of La Crosse in the amount of $60,000 and any extension, renewal, amendment, modification or refinancing of the indebtedness thereunder if the principal
amount of such indebtedness after giving effect thereto does not exceed maximum principal amount of such indebtedness as in effect immediately prior thereto. 

(c) Subject to the rights, if any, of the holders of Senior Indebtedness under this Section 4 to receive cash, securities or other
properties otherwise payable or deliverable to Holder, nothing contained in this Section 4 shall impair, as between Company and Holder, the 

  
 4 

 
obligation of Company, subject to the terms and conditions hereof, to pay to Holder the principal amount hereof and Interest hereon as and when the same become due and payable, or shall prevent
Holder, upon default hereunder, from exercising all rights, powers and remedies otherwise provided herein or by applicable law. 
 5.
Security Interest. 
 (a) Subject to the rights, if any, of the holders of Senior Indebtedness under Section 4, in order to
secure the full and punctual payment of the Secured Obligations (as defined below) in accordance with the terms hereof, and to secure the performance of the obligations of the Company hereunder, the Company hereby grants to the Holder a continuing
security interest in and lien on and to all of the Collateral (as defined below) and all proceeds of, and all other profits, products, rents or receipts, in whatever form, arising from the sale, exchange, assignment or other disposition of
Collateral (the “Security Interest”), whether or not such sale or other disposition is permitted under Section 3 above. “Secured Obligations” means all advances to, and debts, liabilities, obligations, performance
obligations, covenants and duties of, the Company arising under or otherwise with respect to this Note, whether direct or indirect (including those acquired by assumption), absolute or contingent, due or to become due, now existing or hereafter
arising, including, without limitation, (i) to pay principal, Interest, charges, expenses, fees, attorneys’ fees and disbursements and other amounts payable by the Company under this Note (including, without limitation, any Interest which
accrues after the commencement of any case, proceeding or other actions relating to the bankruptcy, insolvency or reorganization of the Company and any other amounts owing hereunder), and (ii) all other amounts payable by the Company under this
Note (including expenses incurred in connection with the enforcement of this Note). “Collateral” means all existing and after acquired real property and personal property of Company and its subsidiaries, tangible and intangible, including,
but not limited to cash and cash equivalents, accounts receivable, inventories, other current assets, leases, furniture, fixtures and equipment, trademarks, trade names, intellectual property and all other personal property. 

(b) Company hereby authorizes the Holder to file such mortgages, financing statements, continuation statements, intellectual property security
agreements and amendments to any of the foregoing, in any jurisdictions and with any filing offices as the Holder may determine, in its sole discretion, are necessary or advisable to perfect or otherwise protect the security interest granted to the
Holder herein. Such financing statements may describe the Collateral in the same manner as described herein or may contain an indication or description of collateral that describes such property in any other manner as the Holder may determine, in
its sole discretion, is necessary, advisable or prudent to ensure the perfection of the security interest in the Collateral granted to the Holder herein, including, without limitation, describing such property as “all assets” or “all
real and personal property, whether now owned or hereafter acquired.” The Company shall furnish to the Holder from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with
the Collateral as the Holder may reasonably request, all in reasonable detail. 
 (c) In case of the occurrence of any Event of Default and
at any time thereafter during the continuance of such Event of Default, the Holder may exercise all rights of a secured party under applicable law (including, without limitation, the Uniform Commercial

  
 5 

 
Code as in effect on the date hereof in the State of New York (whether or not in effect in the jurisdiction where such rights are exercised)). Failure of the Holder to exercise any of its rights
and remedies will not constitute a waiver of the right to exercise the same at that or any other time. 
 (d) Upon the repayment in full of
all Secured Obligations and the termination of any obligations under this Note, the Security Interest shall terminate and all rights to the Collateral shall revert to the Company; provided, however, that if additional amounts are loaned to the
Company by the Holder in accordance with the terms hereof thereafter, the Holder shall again have Secured Obligations and obligations under this Note, and be again subject to the provisions of Section 5 with respect thereto, in addition to all
other applicable provisions hereunder. 
 (e) This Note is a secured general obligation of the Company. This Note ranks junior in right of
payment to the Senior Indebtedness, and pari passu in right of payment with the Pari Passu Debt. The liens securing the Secured Obligations are junior in rank to the liens securing the Senior Indebtedness, and equal in rank to the liens securing the
Pari Passu Secured Obligations. “Pari Passu Debt” means indebtedness under promissory notes that are substantially identical to this Note (but issued on June 19, 2013, July 1, 2013 and July 9, 2013) (the “Pari
Passu Notes”), in an aggregate principal amount such that the original principal amount of the Pari Passu Debt, plus the original Principal amount of this Note, totals $3,500,000. “Pari Passu Secured Obligations” means the
“Secured Obligations,” as defined in each Pari Passu Note. 
 (f) The Security Interest and the liens securing the Pari Passu
Notes may be evidenced by separate mortgages, financing statements and other documents and filings, or may be collectively evidenced by joint documents and filings. The liens securing this Note and the Pari Passu Notes may not be enforced without
the consent of all holders of this Note and the Pari Passu Notes. 
 6. Events of Default. For purposes hereof, the occurrence of any
of the following shall constitute an “Event of Default” under this Note: 
 (a) the Company shall fail to pay any amount payable
under this Note when such payment becomes due; or 
 (b) the Company shall breach, default under or fail to observe or perform any covenant
or agreement of this Note or in any document delivered pursuant hereto; 
 (c) the Company shall commence any case, proceeding or other
action (i) under any existing or future law of any jurisdiction, domestic or foreign, relating to bankruptcy, insolvency, reorganization, conservatorship or relief of debtors, seeking to have an order for relief entered with respect to it, or
seeking to adjudicate it a bankrupt or insolvent, or seeking reorganization, arrangement, adjustment, winding-up, liquidation, dissolution, composition or other relief with respect to it or its debts, or (ii) seeking the appointment of a
receiver, trustee, custodian, conservator or other similar official for it or for all or any substantial part of its assets, or the Company shall make a general assignment for the benefit of its creditors (each, an “Insolvency”); or 

  
 6 

 (d) there shall be commenced against the Company any case, proceeding or other action of a nature
referred to in subsection 6( c) above that (i) results in the entry of an order for relief of any such adjudication of appointment, or (ii) remains undismissed, undischarged or unbonded for a period often (10) days; 

(e) the Company shall take any action in furtherance of, or indicating its consent to, approval of, or acquiescence in any of the acts set
forth in subsections 6(c) or 6(d) above; 
 (f) there shall be a breach or default under any Senior Indebtedness or any Pari Passu Debt, in
each case of any amount, or any other indebtedness of Company in an amount in excess of $100,000 (individually or in the aggregate); 
 (g)
a decree or order is entered appointing any trustee, custodian, liquidator or receiver over the Company or its assets, or adjudicating the Company bankrupt or insolvent, or approving a petition for such relief in any case or other proceeding, or a
decree or order for relief is entered in respect of the Company in an involuntary case under federal or state bankruptcy laws as now or hereafter constituted; and/or 

(h) a judgment or judgments against Company or any of its subsidiaries shall be entered in an amount in excess of $100,000 (individually or in
the aggregate) and any which such judgments is not, within thirty (30) days after the entry thereof, bonded, discharged or stayed pending appeal, or is not discharged within thirty (30) days after the expiration of such stay; then, and in
any such event, (A) if such event is an Event of Default specified in any of subsections 6(c) through 6(g) above, this Note shall automatically (without requirement of notice or other action) (all outstanding principal amount and accrued and
unpaid Interest thereon) and immediately become due and payable in full, and (B) if such event is any other Event of Default, the Holder may, at any time at its option, by written notice to the Company, declare this Note to be immediately due
and payable in full. 
 7. Remedies. Each right, power and remedy of the Holder as provided for in this Note or now or
hereafter existing at law or in equity or by statute or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power, or remedy provided for in this Note or now or hereafter existing at law or in equity or by
statute or otherwise, and the exercise or beginning of the exercise by the Holder of any one or more of such rights, powers, or remedies shall not preclude the simultaneous or later exercise by the Holder of any or all such other rights, powers, or
remedies. No failure or delay by the Holder to insist upon the strict performance of any term, condition, covenant, or agreement of this Note, or to exercise any right, power, or remedy consequent upon a breach thereof, shall constitute a waiver of
any such term, condition, covenant, or agreement or of any such breach, or preclude the Holder from exercising any such right, power, or remedy at any later time or times. The Company acknowledges that a breach by it of its obligations hereunder
will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all
other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 

  
 7 

 8. Miscellaneous. 

(a) Successors and Assigns. The rights and obligations of Company and the Holder of this Note shall be binding upon and benefit the
permitted successors, assigns, heirs, administrators and transferees of the parties. This Note may not be assigned by the Holder without the consent of the holders of the Pari Passu Notes. 

(b) Waivers and Amendments. This Note may not be amended or modified in any manner nor may any of its provisions be waived except by a
written instrument executed by the Company and the Holder. A waiver, modification or amendment by a party shall only be effective if (i) it is in writing and signed by the Company and the Holder, (ii) it specifically refers to this Note,
(iii) it specifically states that the party, as the case may be, is waiving, modifying or amending its rights hereunder, and (iv) the Company has offered to each holder of each Pari Passu Note to make a corresponding parallel modification
to such holder’s Pari Passu Note; provided, however, that the Holder may waive any provision hereunder without the consent or signature of the Company. Any such amendment, modification or waiver shall be effective only in the specific instance
and for the specific purpose for which it was given. 
 (c) Governing Law, Waiver of Jury Trial, Venue. This Note shall be governed
by the laws of the State of New York applicable to contracts entered into and to be performed within New York State. The Company irrevocably and unconditionally consents to the exclusive jurisdiction of the federal and state courts in New York
County for any action, suit or proceeding arising out of or related hereto. The Company agrees not to commence any legal proceeding related hereto except in such court. The Company irrevocably waives any objection which it may now or hereafter have
to the laying of the venue of any such proceeding in any such court and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has
been brought in an inconvenient forum. The Company irrevocably waives any right it may have to a trial by jury in any such action, suit or proceeding. The Company agrees that the prevailing party in any action or proceeding arising out of or
relating to this Note or the transactions contemplated hereby shall be entitled to recover its reasonable fees and expenses in connection therewith, including legal fees. 

(d) Entire Agreement. This Note and any schedules hereto constitute the full and entire understanding and agreement between the parties
with regard to the subject matter hereof. 
 (e) Notices. Any notice, approval, request, authorization, direction or other
communication under this Note shall be given in writing and shall be deemed to have been delivered and given for all purposes (i) on the delivery date if delivered personally to the party to whom the same is directed or transmitted by facsimile
with confirmation of receipt, (ii) one (1) business day after deposit with a commercial overnight carrier, with written verification of receipt, or (iii) three (3) business days after the mailing date, whether or not actually
received, if sent by U.S. mail, return receipt requested, postage and charges prepaid, at the address of the party set forth below (or at such other address as may be communicated to the notifying party in writing); provided, however, that only a
nationally recognized overnight courier shall be used to effectuate the delivery of any such notice to addresses outside the United States and the verified date of receipt of such notice be deemed the date of notice for purposes hereunder.
