FRONTIER EXPLORATION LICENCE 3/14
Results from work on Licence 3/14, as well as regional work, indicate 5 leads and two additional plays at three stratigraphic levels, including the Lower Eocene deltaic complexes, Lower Cretaceous mounded fan complexes similar in seismic character to many of the recent Cretaceous oil discoveries offshore West Africa and Upper Eocene fan mounds.
Stacked targets have been mapped at Eocene (Lower Tertiary), Lower Cretaceous and locally Jurassic levels. This facilitates drilling and testing of several targets with one well.
Eocene Target: The Eocene deltaic sand bodies lie in an ideal position for the entrapment of northward migrating hydrocarbons, generated from mature Middle / Upper Jurassic and possibly Lower Cretaceous source rocks. Updip seal is provided by marine flooding mudstone deposits. Drill depths to the top of the Eocene sand sequence are about 2,500m subsea, in water depths of 700-800 m. Thick reservoir quality deltaic and shallow marine sandstones have been drilled in earlier wells in the region. The mapped sandbodies have the capability to host in-place reserves in excess of one billion barrels.
Lower Cretaceous Target: A large mounded feature with four-way dip closure is onlapped by mud-prone seismic facies. It is interpreted as a basin floor fan deposit, infilling and mounding residual Late Jurassic topography. The structure is undrilled but the seismic signature is significantly different from the mud-prone Lower Cretaceous strata drilled within the basin. The large mounded feature directly overlies Upper Jurassic strata with proven mature source rocks.
