Gulf of Mexico Revolution

High-quality multiclient seismic data processing and interpretation

Contact Us

The 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.

Optimize subsalt illumination

Revolution surveys were designed to enable you to make better-informed, cost-effective strategic decisions during the exploration, 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 dual-coil multivessel full-azimuth acquisition, which employs four vessels—two source and two recording boats—equipped with a 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.

Full-Waveform Inversion

High-resolution velocity models

Derive high-resolution velocity and anisotropy models from seismic data using a two-way wave equation.

Singular Value Decomposition

Noise attenuation tool that targets user-defined frequency and energy levels

Attenuate strong marine noise, including crossflow noise recorded during vessel turns, for successful data processing.

Reverse Time Migration

Advanced two-way wave-equation prestack migration

Accurately image in and below areas with great structural and velocity complexity.
