TGS and Schlumberger have launched the second phase of the Mississippi Canyon ultra-long offset node project in the US Gulf of Mexico.
The next phase will extend the footprint of ultra-long offset data to the Northern Green Canyon protraction area and will be the longest ultra-long offset node project in the world. This area is characterized by complex geology and multiple salt bodies. The combination of ocean bottom node data, used to record ultra-long offsets and full waveform inversion, is expected to deliver a significant uplift to the velocity model which in turn will be used to amend the existing WAZ and Coil data in the area.
Kristian Johansen, TGS CEO, said: ‘Green Canyon continues to experience high levels of E&P leasing activity and is a priority area for deep water exploration activity. This survey will be a critical tool to support our customers’ plans in this region.’
Acquisition of the project is expected to commence in April 2020 with final data available in 2021. TGS and Schlumberger completed phase one of the project in Mississippi Canyon in 2019.
Meanwhile, TGS and Fairfield Geotechnologies are preparing to launch the Channel 3D multi-client survey in Lea County, New Mexico, US.
Permitting is underway for an initial outline of 440 km2 with acquisition set to begin in Q2 2020.
The San Simon Channel, separating the Central Basin Platform from the Northwestern Shelf, is an area with new resource potential in the Permian Basin, said TGS.
The survey is designed to image deeper targets in the Strawn and Atoka algal mounds as well as the Bone Spring Sands and Wolfcamp intervals. Other productive zones with remaining potential include Devonian, Abo, and Paddock horizons.
