Print this pageRecognition of Stratigraphic Anomalies Through Improved
Acquisition
and Processing Technology, Hugoton Embayment
J. I. Yalch
Oil has recently been discovered in the Hugoton embayment, Kansas, through
the use of stratigraphic interpretation of seismic data. This oil is located in
traps of channel sands in the Morrow and Chester formations.
Current seismic data, from which producing well locations were selected, were
"deprocessed" to simulate older data. Field acquisition and seismic processing
parameters were duplicated for six of the prior 24 years. This simulated data
shows the logical progression of field acquisition and processing technology.
This method also demonstrates the stratigraphic appearance of the anomaly on the
data during those years.
Both field acquisition and processing parameters and techniques are reviewed
on each of two lines. The resulting impact of the changes on each of the
sections and its anomaly is noted as we progress through time.
In addition to showing full sections for each of the six years, blowups of
the actual anomaly location on each of the simulations are shown with the
original data
for easy comparison.
