Today in deep water and new frontiers, the ability to understand what is below complex structures is critical in defining the subsurface and better understanding the petroleum system of an area. Make or break risk and economic project decisions can depend on understanding this complexity.

In this first edition of Insights, we highlight, in four categories, a selection of recent publications meeting the challenges of imaging complex subsurface structures.

  • Wavefield reconstruction based on multicomponent data
  • Full-azimuth data acquisition
  • Full waveform inversion for velocity model building
  • Seismic-guided drilling
Defining Complex Structures and Prospects
Full Waveform

Full-Waveform Inversion

High-resolution velocity models for a range of E&P scenarios and geological settings

FWI uses a two-way wave equation to derive high-resolution velocity and anisotropy models from seismic data.

Seismic Guided Drilling

Seismic-Guided Drilling Service

Real-time well placement optimization

Enhance well planning and while-drilling decisions with 3D pore pressure and hazard prediction ahead of the bit.

Density contrast section generated by joint PP-PS inversion - needed for distinguishing fizz gas from commercial gas reserves.

Multicomponent Applications

Ocean bottom seismic data applications for resolving seismic and geological challenges

Reduce the risks involved in reservoir development, routinely extending the use of seismic data into the reservoir domain.

Generalized Matching Pursuit

Wavefield separation technique for over-under or dual-measurement marine data

Perform high-fidelity wavefield reconstruction and 3D deghosting of multimeasurement marine streamer data.
