2D/3D Pre-stack Time and Depth Migration

We have a broad portfolio of seismic migration algorithms to support a wide range of imaging objectives. Complex wave phenomena, target-oriented and wide azimuth seismic acquisitions, and extended velocity model descriptions that incorporate anisotropy must be supported by pre-stack imaging solutions.

SeisLink offers a full range of 3D pre-stack time and depth migration methods, with velocity model building using innovative and practical iDepthing well calibration and reflection tomography. SeisLink's Earth imaging solutions include curved-ray pre-stack time migration, flexible, Kirchhoff depth migration, reverse time migration. Collectively, these migrations can be applied to solve a wide range of imaging objectives, such as salt overhang, sub-salt, thrust fault, fault shadows, and rugged terrain imaging, and accommodate a variety of imaging acquisitions, including wide angle and wide azimuth, OBC and other multi-channel recordings.

Migrations include special support for high performance computing, including cluster configurations, such as Linux clusters and symmetric configurations with multiple CPUs.
