Abstract
Abstract: Structural and Stratigraphic
Interpretation Utilizing 
3-D
Seismic Coherence
3-D Seismic CoherenceBy
President, Coherence Technology
The application of 3-D coherence processing
provides the oil community with an
exciting new technology which significantly
impacts the economics associated
with improved 3-D interpretation accuracy
and productivity, while extracting a vast
amount of information from the 3-D
seismic
waveform which would otherwise be
overlooked.
The technique is equally useful to geophysicists, geologists, and reservoir engineers to help build a more accurate reservoir model. Working closely with the interpretation staff, the specialized coherence processing geophysicist can optimize the parameters to focus the features of interest. The spatial changes detected in the seismic waveform can readily be related to geologic features and depositional environments. Faults and fracture systems can now be spatially imaged and directly mapped from the coherence cube without the tedious task of drawing faults on each vertical section and proceeding blindly without prior knowledge of their spatial position.
A case study focuses on a south Louisiana data set, the impact that coherence technology had on the interpretation, and the economic impact realized.
