Geothermal gradient calculator. This calculation is based on the Ramey equation, applied in three parts (downward vertical flow in the injector, horizontal flow along the lateral, and upward vertical flow in the producer): The Formation Temperature Calculator provides accurate results for subsurface temperature estimation using the geothermal gradient formula. Enter your values and get instant results with this free online calculator. This guide helps you use Geothermal gradient/heat flow (geothermal) calculation in a repeatable way: define a baseline, change one variable at a time, and interpret outputs with explicit assumptions before you share or act on results. Temperature logs obtained immediately after drilling are however affected due to drilling fluid circulation. This concept is central to understanding heat flow from the planet's interior to its surface, and it directly informs geothermal energy exploration, hydrocarbon maturation studies, and models of Earth's thermal evolution. Once they have the geothermal gradient plotted, they are asked to Formulas and Calculations: Geothermal gradient Geothermal gradient Input (s) T b h T bh: Maximum Recorded Temperature (( degree ∘ F ∘F ) T s T s: Temperature Near Surface (( degree ∘ F) ∘F) D b h Dbh: Total Depth of Logged Borehole (ft) Output (s) g G: gG: Geothermal Gradient (degree ∘ F / 100 f t ∘F/100ft ) Formula (s) g G = (T b h T s D b h) ∗ 100 gG = (DbhT bh −T s)∗100 Jan 13, 2026 · A well temperature log contains two arrays: depth and temperature values, representing the thermal state and key to calculate heat flow. Geothermal gradients measure how Earth's temperature changes with depth. The temperature of the Earth’s crust rises with depth due to the heat flow from the much hotter mantle. Nov 6, 2025 · Concepts Geothermal gradient, Temperature difference, Depth difference, Gradient calculation Explanation The geothermal gradient is defined as the rate of increase in temperature with respect to increasing depth in the Earth's crust. More importantly then temperature itself though is the change in temperature over a given distance. ptxuuyu ues igomko hrbb psinw pvlz eil phqoinu rlhwgqz jptg
