Paper Summary
In recent years, the Sao Tome and Prncipe Exclusive Economic Zone (STP-EEZ) has been the subject of significant attention from major oil companies, resulting in applications for exploration licenses and farm-in activities over nine blocks. PGS reprocessed its MultiClient library data using modern processing techniques and conducted a basin analysis study to help understand the recent interest. The study shows that all the elements of a working petroleum system are present in the waters of the STP-EEZ. Continental and transitional crust provide structures and source rocks and PGS basin modelling reveals that these sediments are mature for oil and gas. Long-lived fluvial systems provide quality reservoirs fed from numerous sedimentary catchment areas.
