Modelling low velocities in carbonate karst zones and improving sub-karst images in the Gulf of Mexico

May 11, 2011
A velocity anomaly zone with high contrasts and small wave length variations is often a challenge for conventional depth imaging. It requires model.

Horizon and fault constrained tomography to model fault induced velocity discontinuities in the hoop fault complex area

May 9, 2011
We present a case study that uses different methods of addressing a sharp velocity contrast across a major fault boundary in the southwestern Barents Sea..

Automated RTM-based DIT scans for salt interpretation and model building

May 2, 2011
Reverse Time Migration (RTM) based Delayed Imaging Time (DIT) scans have been used routinely in production to update velocity models in subsalt or low.
