Subsurface pressure data from 82 out of 84 exploration and appraisal wells have been used to generate reservoir pressure maps.
In addition, the burial and pressure history of the region has been defined using AFTA (apatite fission track) data, together with vitrinite reflectance and sonic velocity analysis, from 21 of the study wells. The study addresses issues such as: overpressure distribution, expansion during uplift, seal breach and unexplained dry holes.
