Most subsurface temperature data available for this study of the geothermal regime of Oklahoma are non-equilibrium temperatures represented by bottom-hole temperatures from mud- drilled wells. Equilibrated temperatures including temperature logs, temperatures from shut-in gas well pressure tests, and from air-drilled wells are available in less than half of the study area.
