Formation pressure

bodyp_i
 before the well was put on stream:  at which the field has been formed before anthropogenic invasion, either directly or indirectly through the connected reservoir(s).


Usually picked up from the first exploration well but can be adjusted if their is indication that it's been affected by the connected reservoir(s).


As the pressure may change at different field areas due to formation top variation the initial formation pressure is recalculated to some datum thus making

bodyp_i = p_e(t < 0)
frequently denoted as  LaTeX Math Inlinebodyp_0
 a one number for the whole connected reservoir.
