Karnes County Sits in the Heart of the Eagle Ford Shale
Karnes County sits on the Railroad Commission's Eagle Ford Shale affected-counties list. The formation runs thousands of feet down. Pump jacks and pads around the ranchland are the visible part of that oil story.
Surface ownership and mineral ownership are not always the same. A seller can own the dirt while someone else owns the oil and gas below it. The minerals may also be leased already. Ask the title company to spell that out before closing.
The Railroad Commission posts Eagle Ford permits, production files, and historical data. Those records give you a first look at nearby activity. Title work tells you whether minerals come with the land.
