Our first acquisition was the Grayburg-Jackson oil field which is a waterflood property and is operated by the HNRA subsidiary LH Operating, LLC (“LHO”).


The Grayburg-Jackson oil field is located on the Northwest Shelf of the Permian Basin in Eddy County, New Mexico. According to the United States Geological Survey, the Northwest Shelf contains the largest recoverable reserves among all the unconventional basins in the United States. LHO’s holdings comprise 13,700 contiguous leasehold acres, 342 producing wells, 207 injection wells and 1 water source well for a total of 550 wells on 20 federal and 3 state leases.

Land & Ownership

The oil field has several large reservoir structures that range from as shallow as 1,500 feet deep to 4,000 feet deep. The field has attainable proven reserves of approximately 20 million barrels of crude oil and 6 billion cubic feet of natural gas. All field production of the Company is being sold under long-term contracts to various customers in the USA.


LHO was a privately owned company that operated the Grayburg-Jackson field (the “field”) from early 2020 after acquiring the property in late 2019. The 2020 baseline production level was approximately 500 barrels of oil equivalent (BOE) per day. LHO’s production has increased from the baseline production of 500 BOE in 2020 to today’s range of 1,250-1,450 BOE per day by the implementation of Zone 7R waterflooding.

We plan on doing the same successful workovers which will expand the existing waterflood patterns field-wide. Management expects to increase daily production to nearly 4,000 barrels of oil and oil equivalent in the next three to four years in accordance with a reserve report by William M. Cobb & Associates, Inc. a 3rd party engineering firm. Click the button for the latest published reserve report.
