Sitting at the meeting point between the Benin Embayment and the Benue Trough, this 3D dataset covers an area over blocks OPL314, OPL315, OPL321 and OPL323. This is the missing link that enables the integrated exploration of the north and western Gulf of Guinea, joining the West Africa Transform Margin to the Niger Delta Basins.
The dominant and prolific petroleum system in neighboring blocks produces from the Agbada Formation turbiditic reservoir unit underlain by the oil mature Akata Shale marine source rock. From the 1990s to as recently as in March this year, many fields have been discovered to the south and east, including the giant Bosi (1996), Erha (1999) and Oyo North (2018).
These surveys were acquired in 2004 and initially processed in the time domain. Revitalization of the data, to reveal this structurally challenging environment will be achieved using the modern processing and imaging techniques.
A suite of optimized denoising algorithms, coupled with a full deghosting sequence, will improve the data bandwidth and signal-to-noise ratio. The multiple attenuation sequence will eliminate stubborn and complex multiples, and a full-velocity model building sequence in the depth domain, together with a depth migration, will improve the image integrity.
