EXTEX OPERATING COMPANY, Upton County, Texas
Mineral interests on the Upton County Appraisal District's 2026 certified roll.
The same name and mailing city appear in 10 other covered counties. Borden County (5 interests) · Gaines County (21 interests) · Hockley County (3 interests) · Kent County (7 interests) · Midland County (3 interests) · Reagan County (20 interests) · Stonewall County (14 interests) · Ward County (1 interest) · Winkler County (8 interests) · Yoakum County (4 interests). A shared name and mailing city are strong evidence that this is the same owner. They are not proof, and the appraisal districts do not share an identifier.
This is one county, not this owner’s holdings. The site holds mineral rolls for 114 of 254 Texas counties, so EXTEX OPERATING COMPANY may hold interests elsewhere that this page cannot show. Absence is not evidence.
The ground
The Original Land Survey abstracts this owner holds an interest in, on the Commission’s own survey grid. Click any outline to open that abstract.
12 of 29 interests are on the map, across 10 abstracts. An interest is placed only where the district’s legal description names an abstract this site can resolve. The rest are listed below without a location — that is a limit of the description, never a claim that the property is outside the survey grid.
