Walker County, TX Oil & Gas Discussion archives

A family I work for owns various mineral interest located under approximately 52 acres in various tracts in the W. Edinburgh Survey, A-183 and the J. M. Randolph Survey, A-737 in Walker County, Texas. Information indicates EOG Resources of Houston operates a producing well on one of the tracts.

I'd like to know if Walker County places an appraised value on undivided mineral acreage. If so, how do I conduct the search?
Does the Walker County Appraisal Distract place an appraised value on the undivided interest in a minerals and/or producing wells? If so, how do I conduct the search?
Anyone have an idea of the value of minerals or would I need to contact an Oil & Gas Landman?
Thank you. Please contact me if you have any questions. Joe Lovelace
