ABSTRACT:
A new technique for interpreting pressure data measured during a formation test. The new technique uses an exact spherical flow model that considers the effects of flow line storage and that can be solved in closed, analytical form. This technique generates a type-curve that matches the entire measured pressure plot and that can accurately predict ultimate formation pressure during formation testing from a pressure plot that has not achieved steady state values near the formation pressure.
