Title: Approximation of Thermal Gradient in Southeastern New Mexico Using Bottom-Hole Temperatures from Electric Logs

Author(s): W. K. Summers (2)


Bottom-hole temperatures and depths were obtained from electric logs of wells in Chaves, Eddy, and Lea Counties, New Mexico. Thermal gradients obtained by linear regression ranged from 0.70°F/100 to 0.90°F/100 ft. Despite considerable "noise" in the data, these values compare favorably with earlier values reported in 1937 of 0.707°F/100 ft for the interval 1,500-4,000 ft and 1.006°F/100 ft for the interval 4,000-6,000 ft in a well in T20S, R29E, and with the average of 0.73°F/100 ft obtained from nine temperature logs of wells in the area. Linear regression of bottom-hole temperatures and depths in electric logs is a valid technique for estimating geothermal gradients.
