EXHIBIT 10.1

AGREEMENT

This Agreement is made and entered on the 15 day of September, 2017, by and between Altavista Energy, Inc., a Kansas corporation ("Seller"), and Mid-Con Drilling, LLC, a Kansas Limited Liability Company ("Buyer"), governed by the laws of the State of Kansas.

In consideration of the mutual covenants and Agreements contained herein, the sufficiency and adequacy of which are mutually acknowledged, the Parties agree as follows:

1. SALE OF PROPERTY. Seller is the owner of 100% of the Working Interest in and to the oil and gas leases described in Exhibit A attached hereto (the "Leases"). Seller agrees to sell its working interest in the Leases in current condition together with all of its right, title and interest in and to all rights, privileges and easements appurtenant thereto, free and clear of all liens and encumbrances, to Buyer for the total sum of Five Hundred and Thirty Thousand Dollars ($530,000.00), including all personal property now in place on the Leases. The purchase price shall be paid as follows:

Five Hundred and Thirty Thousand Dollars ($530,000.00) at Closing to be paid in collected funds.

Seller has full power and lawful authority to bargain, grant, sell, mortgage, assign, transfer, convey and grant 100% of the Working Interest in the Leases in the manner and form provided, without obtaining the waiver, consent or approval of any lessor, sublessor, governmental agency or entity or party whomever or whatever.

2. ASSIGNMENT FORMS. Seller shall at Closing assign to Buyer in "as is" condition, free and clear of all liens and encumbrances, all its Working Interest in the Leases. All assignments will have an effective date of October 1, 2017.

3. CLOSING. Closing shall be on or before Monday, October 2, 2017, at a time and location mutually agreeable to Buyer and Seller. Buyer shall deliver to Seller the full payment of Five Hundred and Thirty Thousand Dollars ($530,000.00) at Closing to be paid in collected funds.

4. POSSESSION. Time is of the essence. Upon full payment due on Closing, Buyer shall be entitled to possession of the Leases and the personal property described in the Assignment forms on the date of Closing and not before. Failure to close on or before October 2, 2017, shall render this sale null and void.

5. DEFAULT. This is an absolute sale and the Parties acknowledge they will change their respective positions at the signing of this Agreement and each commit to the performance of acts required of them by the terms of this Agreement. The Parties agree that it is not possible to quantify the losses which may accrue to the Seller or Buyer should either not perform this Agreement, and thus should either party default on this Agreement the Agreement becomes null and void and both Parties will have no further obligation to one another.

6. SELLER RETENTION. Seller shall continue to operate and produce all of the leases until the date of Closing. Seller shall retain all production from said operations during such executory period and shall pay and be responsible for all expenses and liabilities to the effective date of the Assignment forms. Seller intends to sell all production on or before September 30, 2017. All continuing services such as utilities, pumper fees and related expenses shall become on the date of Closing Buyer's liability.

7. TIME IS OF THE ESSENCE. It is very important to Seller that this sale is performed in a prudent and timely manner. Time is of the essence. Thus, all things which are required to be done by certain dates must be done; otherwise, such failure shall be deemed a material default.

8. CONSENT OF SELLER. Although Buyer shall not take possession until Closing, Buyer shall be permitted to come upon the Leases to make such inspections of the properties as it may reasonably desire. Nothing shall be removed from any of the Leases while making such inspections and respect must be paid to the landowner rights where the Leases are located.

9. JOINT DRAFTING. The Parties shall be considered joint drafters of this Agreement so as not to construe this contract against one Party as drafter more than the other.

10. COUNTERPARTS. This Agreement may be signed in two or more counterparts.

11. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon, and inure to the benefit of, the Parties hereto and their respective successors, heirs, administrators and assigns. Either Buyer or Seller may assign all or any portion of their rights hereunder to a third party.

In Witness Whereof, the Parties have entered into this Agreement as of the date opposite the signatures below to be effective on the date last signed.
