CGG Subsurface Imaging, part of CGG’s Geoscience division, has delivered state-of-the-art broadband 4-D seismic results ahead of schedule from BP Angola’s latest monitor survey offshore Angola, the company said on Oct. 2.

This achievement builds on previous 4-D seismic processing projects undertaken for BP Angola.

The enhanced imaging volumes from the Greater Plutonio development in the Lower Congo Basin were delivered four weeks early for this time-critical BP project. Faster than expected completion of this workflow, which included the latest advanced proprietary deghosting and demultiple technology, was made possible by continued investment in CGG’s high-performance computing capacity and the advance of its technology, along with close collaboration with the BP team.

“We were very impressed by the CGG team’s commitment to achieving an early delivery of the data on what was already a challenging schedule. The early delivery of results will accelerate our active reservoir management program for this field,” Radwa El Zidan, geophysicist from the BP-Angola asset team, said.
