Pore Pressure Prediction Based on High Resolution Velocity Inversion in Carbonate Rocks, Offshore Sirte Basin, Libya

As part of the exploration process for a prospective area in the Sirte Basin, offshore Libya, geopressure prediction was performed on 200 km2 of 3D seismic data in two subsets of 100 km2 each from the NC202 survey. Fluid and fracture pressure interpretation was based on well control and seismic interval velocities. Offset well control included one well located within the seismic survey area. This well contained no RFT or MDT data, but did have mud weights (MW), leak-off tests and wireline logs. A second well near the survey was tied by a 2D seismic line. This well contained MDT and DST data.
