Multiclient Latest Projects: Gulf of Mexico Revolution Full-Azimuth & Long-Offset Multiclient Seismic Survey

High-quality multiclient seismic data processing and interpretation

Schlumberger Revolution surveys comprise high-fidelity dual-coil multiclient seismic data from more than 36,260 km2 of diverse deepwater Gulf of Mexico locations, each sharing characteristics of complex salt geometries and structures.

Surveyed basin areas:

  • Western Gulf frontier areas with Lower Tertiary (Wilcox) plays
  • Core area of subsalt targeting Middle to Lower Miocene plays
  • Lower Tertiary (Wilcox) with subsalt Pliocene plays
  • Central Gulf area over the Lower Tertiary plays

Overcome complex salt challenges

Combining ultralong offsets with high-end processing technologies like full waveform inversion and anisotropic reverse time migration, Revolution surveys improve visualization in the most complex subsalt geometries, including complex salt structures, rugose salt tops, shallow salt bodies, and, steeply dipping sediment areas.

In the image above, slide the bar left and right to see a comparison.

In this Revolution VIII data example, the right image shows an enhanced stack after full waveform inversion (FWI) plus subsalt update, while the left image shows an enhanced stack from a comparable wide-azimuth dataset with FWI plus subsalt update. The improved steep dip imaging, clearer salt base, and subsalt imaging seen on Revolution VIII data give a clearer understanding of the region’s geologic complexities and contribute to improved reservoir positioning and optimal drilling decisions.

Achieve optimal subsalt illumination

The Revolution surveys were designed to enable you to make better-informed, cost-effective strategic decisions during the exploration phase as well as the development and production phases. With integrated technology and geoscience expertise, these surveys deliver improved imaging in and around challenging structures, providing

  • increased subsalt illumination using both full-azimuth and long-offset data
  • more detailed illumination for fracture and fault mapping
  • improved anisotropy and anisotropic velocity modeling
  • robust information to improve velocity model building in areas containing salt bodies.

Dual Coil Shooting Acquisition technology

The full Revolution survey dataset was acquired using WesternGeco Dual Coil Shooting multivessel full-azimuth acquisition, which employs four vessels—two source and two recording boats—equipped with the Q-Marine point-receiver marine seismic system. Recording boats continuously shoot in a series of interlinked circles with 6,250-m radius, and data are acquired over the full-azimuth, 360°, and over the full offset range to deliver a 14-km long-offset dataset.
