Fossil Petroleum LLC has continued its drilling program in East Texas with the drilling of a new well in Cass County, according to state drilling records.
The San Angelo, Texas-based operator drilled the well during June 2026, marking the company’s third well drilled in Cass County since returning to active drilling operations in 2024. Prior to its recent East Texas activity, Fossil Petroleum’s drilling program was primarily focused in Irion County, Texas.
Since 2017, Fossil Petroleum has drilled a total of 13 wells across Texas. The company’s drilling activity has been concentrated in three counties:
- Irion County – 9 wells
- Cass County – 3 wells
- Runnels County – 1 well
Most of Fossil Petroleum’s drilling occurred between 2017 and 2020 when the operator drilled a series of Hamilton Ranch development wells in Irion County. After a period of limited activity, the company resumed drilling operations in 2024 with new projects in Cass County.
