Temperature gradient in well is sometimes estimated by either a temperature survey or running wireline formation tools. Meanwhile, well is generally full of a fluid whereby fluid movement is governed by either force convection in the flowing condition or free convection in the shut-in condition. Both mechanisms influence on the estimated temperature gradient for some extends. Since estimating reservoir temperature at datum depth needs a temperature gradient (or geothermal gradient), I seek any advice that can shed a light on the most reliable method for estimating the temperature gradient.
I actually use the finite volume method f.v.m and the Fortran software to run the code.
This link for a good book for the finite volume method.

Do you need to put some special emphasis on temperature gradient ? In general if you can simulate temperature distribution ，you can easily calculate the temperature gradient by post-processing. As for temperature gradient, ANSYS product is of help, and in the UDF module you can simulate temperature distribution. If you wanna conduct some experiments that is another story.
