Introduction to October Focus: Intro to Seismic Processing

Rob Holt

This month we feature four articles on different aspects of seismic processing. As a whole they capture many of the recent advances in the field of seismic processing, which slowly but surely evolves as time goes by.

6D Interpolation of Seismic Data – Rationale, Practice and FAQs

Mark Ng and Dan Negut

For many reasons, such as acquisition limitations, economic constraints, and merging data of various shooting parameters from different vintages, seismic data needs to be regularized, upsampled, reconstructed and interpolated. Furthermore, a common deliverable of interpolation is regularized prestack data which will improve many state-ofthe- art inversion processes and migration imaging.

A Well-Guided Processing Approach

Regan Kennedy, Josh Curtis, Greg Staples and Kristof De Meersman

In any processing flow countless parameter choices are made, including which processes to apply, what order to apply them in, and how to parametrize them. In seismic processing, many different but sound choices can all produce similar images. These similar images may not be geologically equivalent when examining all products… continue reading.

Geologically Constrained Anisotropic Depth Imaging in the Central Burma Basin, Onshore Myanmar

Rob Vestrum, Christophe Gonguet and Tim MacArthur

Understanding the local structural styles and sedimentary sequence is key to constraining depth-migration velocity models in structured onshore seismic data. Judicious application of geologic constraints in the model building resulted in compelling imaging improvements on 2D seismic in this structurally complex area.

Seismic Reprocessing for Improved Imaging in the Permian Basin

Rob Holt

Seismic data enables us to visualize the subsurface in three dimensions with sufficient vertical resolution to identify all but the thinnest of our oil and gas reservoirs. Using seismic data, interpreters map changes in reservoir depth, thickness and character between well locations, and identify the larger faults that create potential… continue reading.

Sonic Velocities and Depth Conversion

Robert Pickering

The current method(s) of converting seismic time data to depth are methods created to work-around the lack of access to an adequate volume of velocity data. Access to sonic velocities provides the opportunity to move all variables of the depth equation into the depth domain where mathematically and geologically correct… continue reading.

CSEG Distinguished Lecture Tour 2016/2017

Laurie Weston Bellman

It dawned on me about two months after accepting this role as the 12th CSEG Distinguished Lecturer that, aside from being an honour to be chosen, it might be a significant commitment. Dr. Don Lawton (2016/2017 CDL Committee Chair and 2013 CSEG Distinguished Lecturer) had sent out 30-plus emails, copying… continue reading.
