After every70-75ft the temperature inside the earth increases by1 Fahrenheit which is called Geothermal gradient.
It depends on the Ambient temperature at the surface and the region where you are drilling well.
Different Reservoirs have different pressures and Temperatures.
It depends on the type of reservoir and its depth, Original Oil In Place, GOR and WOR ratios.
We have several types of Gas reservoirs and many types of Oil reservoirs.
