SOUTHWEST PETROLEUM CO, Brown County, Texas
Mineral interests on the Brown County Appraisal District's 2026 certified roll.
The same name and mailing city appear in 24 other covered counties. Bee County (3 interests) · Crane County (20 interests) · Dawson County (148 interests) · Eastland County (27 interests) · Foard County (3 interests) · Frio County (5 interests) · Glasscock County (149 interests) · Hansford County (81 interests) · Hardin County (35 interests) · Jim Hogg County (2 interests) · La Salle County (40 interests) · Limestone County (244 interests) · Medina County (3 interests) · Midland County (542 interests) · Mitchell County (2 interests) · Nolan County (35 interests) · Nueces County (77 interests) · Orange County (14 interests) · San Patricio County (1 interest) · Shelby County (84 interests) · Tarrant County (1,204 interests) · Titus County (19 interests) · Upton County (242 interests) · Victoria County (13 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 SOUTHWEST PETROLEUM CO may hold interests elsewhere that this page cannot show. Absence is not evidence.
