This heat propagation determined by the rock's thermal conductivity. The rock's thermal conductivity is a quantity that describe the ability of rock to transfer the heat. This quantity depends on the rock's lithology, its porosity, and fluids which fill the pore (Horai and Simmons, 1969). The higher the rock's thermal conductivity, it becomes easier for the heat flow to move through it. With the same term, the heat flow will pass through the rock easier if the rock filled with water than hydrocarbon. This was confimed by the result of research by Clauser and Huenges (1995) who said that the water content in sandstone affect the sandstone's thermal conductivity.Technically, we can identify the amount of the effect of the hydrocarbon in reducing the amount of heat that propagate to the surface by the result of calculation of the heat popagation at a certain point and compare it to the measurement of the surface temperature at that point, assuming that the measured surface temperature is the temprature come from the mantle. |
