CGG has won two large-scale complex seismic reprocessing contracts from PTTEP covering two regions offshore Malaysia.
CGG has won two large-scale complex seismic reprocessing contracts from PTTEP covering two regions offshore Malaysia.
The company will conduct merged reprocessing of surveys from many vintages, including towed-streamer and OBC seismic data from offshore Sabah and Sarawak. The fast-track products are expected by mid-next year and final workstation products will be delivered by the end of 2021.
The images are expected to improve the definition of producing reservoirs, enable enhanced planning and drilling of future wells, and open up new plays for near-field exploration at deeper intervals. This region has a complex highly faulted subsurface where scattered gas bodies mask the target reservoir on existing data sets. To unmask the gas wipeout, remove distortions at the reservoir level and image the bounding faults, CGG will apply its latest workflow including proprietary imaging technologies, such as high-frequency full-wavefield Time-Lag FWI (HF-FWI), Q-compensating least-squares (LS-Q) Kirchhoff PSDM and LS-Q RTM, which have been fine-tuned over many similar projects in the region. These technologies will also be focused on improving imaging of the deeper exploration targets with enhanced amplitude, resolution and continuity in the mini-basins and improved definition of the steeply dipping folds underneath the main unconformity.
Meanwhile, CGG has won a three-year contract extension from Petroleum Development Oman (PDO) to continue providing land seismic imaging services at its dedicated processing centre (DPC) in Muscat.
The company will continue to implement its latest proprietary algorithms to bring step-changes in the imaging of the ever-growing volumes of land data, characterized by complex near-surface conditions and strong multiples. CGG will also aid PDO’s transition from cable to node multi-source acquisition and the incorporation of machine learning into its workflows.
PDO operates a concession in Oman that covers almost one third of the country’s land surface area.
