Finally to really understand what they have Chevron is going to have t run a BHP Test(bottom hole pressure test). They will run an electronic tool down the production pipe all the way to the zone and shut the well in at the surface. They then measure the pressure build up in the reservoir. From these gradients they can calculate Z-Factor and determne reservoir size, permeability, and even the best flow rate to flow the reservoir at to produce the best API crude they can and extend the reservoirs life the best.
