Modelling low velocities in carbonate karst zones and improving sub-karst images in the Gulf of Mexico
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
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..
Reverse Time Migration (RTM) based Delayed Imaging Time (DIT) scans have been used routinely in production to update velocity models in subsalt or low.
