Abstract
The solution of Fourier's one-dimensional steady state conduction heat flow equation for two layers-model has been solved using the analytical techniques and applied to part of Niger Delta sedimentary basin. The temperature-depth profile obtained shows a linear increase in temperature with depth. The internal properties affecting the thermal structures are the thermal conductivity and heat production. Comparison of measured and computed temperatures for some wells showed good agreement with minor variation ranging between -4.0 to 5.0 oC. This model can be used to determine thermal properties of other parts of the basin with little adjustment of the rock properties values.
