Need referrals for consulting geologists

Forum members: We are in search of a consulting geologist that has knowledge of the McClain County, Oklahoma oil producing area. We’d like to hire an individual that’s not a landman or broker to give us an unbiased assessment. Thank you for all suggestions. It’s greatly appreciated as we live in California. Btw, congrats on the forum anniversary. There’s a wealth of info here and the experts stand apart. It’s a treasure to be sure. Terry
