WebThe bottomhole temperature at 2.2 km was found to be 70°C. The mean surface temperature for the region is 24°C. Determine the geothermal gradient Gt and a temperature of the formation at a depth of 1,700 m. Solution Solving for Gt from Eq. (2.9): The formation temperature at D =1.7 km is obtained from Eq. (2.9): WebJan 27, 2024 · This data set is comprised of bottom hole temperature, depth, and time since circulation that have had seven different correction factors run on the data. The data was consolidated into 6x6 mile cells and a least squared algorithm was used to create one temperature gradient (per correction factor) for that particular cell. Citation Information
