Lavaca County - 25 acres outside of Moravia at CR 260 and CR 261

Does anyone know of any potential rigs that might be moving in the Moravia area in Lavaca County? My parents have the top and bottom rights to 25 acres ouff CR 260 and CR 261 but none of us live there. My dad said that a guy with the siesmic testing called to get on the property a few months ago and never heard anything from him since. There was a lady my mother met there a few weeks ago that said the siesmic guy she talked to said there is tons of oil right in that area? Does anyone know if this could be true or not?
