Determining The Migration Paths Through Utilization of Pore Pressure, Belayim Land Oil Field, Gulf of Suez, Egypt: a case study

Abstract

Deciding on the next wellbore site for field development in oil and gas exploration is a process involving risks and large investments. Selecting a more accurate location based on hydrocarbon migration is one of the ways to reduce the risk in the operations. This study provides an overview to evaluate the pore pressure for main reservoirs in the Belayim oil land fields. These reservoirs are included in the Miocene Belayim, Kareem, and Rudies formations. Calculation of corrected drilling exponent (Dxc) is used in the present research based on electric logs. These calculations specify the pore pressure values and are used to make subsurface mapping that is utilized to observe the migration paths. The study revealed high to low pore pressure in the northeast-southeast trend in Belayim and Kareem formations in the study area. However, the high to low pore pressure trend is inversed and changed to northeast-southwest. Better locations of the field development are located in low pore pressure zones.
