Recently acquired 3-D seismic data in the
Wilburton gas field provides additional insights into the structural complexity
of the area. The use of seismic attributes of instantaneous amplitude, and the
first and second derivatives of the instantaneous amplitude further enhance the
seismic imaging of the Atokan and older strata. In
addition, the first and second derivatives of the seismic data increase the
vertical resolution. These enhancements to seismic data make it possible to
interpret the structures in upper Atokan to Hunton strata The seismic attribute data also makes it
easier to calculate the structural shortening in the Arkoma Basin due to
thrusting. The calculated structural shortening in the basin is of the order of
21 percent.
