Owner city
DALLAS, TX
The same name and mailing city appear in 3 other covered counties. Culberson County (124 interests) · Midland County (241 interests) · Taylor County (1 interest). 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 WINDHAM MINERALS LTD may hold interests elsewhere that this page cannot show. Absence is not evidence.

123 of 136 interests are on the map, across 25 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.
