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.
