Grid tomography as a tool for pore pressure prediction. A case history

Pore Pressure Prediction in HP/HT environment

“…In a more regional study, the pressure model can be integrated in the petroleum system modeling to recreate the story of the basin. A correct estimation of geopressure also contributes to obtain a successful and efficient drilling phase in terms of reaching the total depth at the right position (geological target), using the minimum mud weight required to balance the formation pressure without exceeding the fracture pressure (reservoir target) and using smaller and fewer casing runs without forget safety requirements (drilling target) (See Cibin P. 2006) For all these reason the attempt to obtain increasingly accurate pore pressure models is very important. In this paper we show the pore pressure results we got using geophysical techniques as they become more refined.…”
