JDZ 3D

Integrated exploration package for the Joint Development Zone of Nigeria & São Tomé e Príncipe
Website Map for Survey JDZ_MC3D
An integrated geoscience approach that incorporates reprocessed 3D seismic together with processed results of operator well log data and reports has been used to identify a number of targets and improve understanding of the hydrocarbon systems.
The JDZ is situated in the outer compressional zone of the Niger Delta. East-west trending toe thrusts are typically observed in this region and numerous stacked reservoir targets and nearfield development opportunities have been identified.
3D seismic reprocessed in combination with well-log data to create a high-quality fully migrated product with a modern AVO friendly sequence that includes prestack time migration.
