Summary High-density wide azimuth (WAZ) land surface acquisitions have demonstrated superior imaging capabilities. However, processing of such data exhibits several challenges related to the traditionally poor signal-to-noise ratio of land data and t

The superior imaging capabilities of wide azimuth (WAZ) are now well established. Processing such acquisitions rquires adaptation of the processing workflows and tools. For example the recorded azimuthal information must be kept and the tools should

Publikováno v: 71st EAGE Conference and Exhibition incorporating SPE EUROPEC 2009.
Velocity model building for time imaging generally involves an iterative process involving several loops of PreSTM, picking, and velocity update. We propose a new approach allowing the full interpretation of kinematic information picked on PreSTM gat

Kinematic Invariants Describinh Locally Coherent Events: An Efficient and Flexible Approach to Non-Linear Tomography

Publikováno v: 71st EAGE Conference and Exhibition - Workshops and Fieldtrips.
Slope tomography allows estimating velocity models from locally coherent events. These events can be picked in the prestack depth or time migrated domains, and then de-migrated into the prestack time un-migrated domain, providing what we call kinemat

From time to depth imaging: An accurate workflow

Publikováno v: SEG Technical Program Expanded Abstracts 2007.
We present a new strategy for depth velocity model building from pre-stack time migrated gathers. It is based on a dense volumetric dip and residual move-out (RMO) picking in the prestack time migrated domain. The kinematic information is demigrated
