Figure 5. Integration of subsurface geology, geophysics, and soil gas
geochemistry. A. Combined geological and seismic
interpretation
of location of
Morrow incised valley and sandstone fairway. B. Anomalous ethane microseepage
pattern detected at the surface from vertical migration from the underlying oil
reservoirs. C. Structural cross section A-A' illustrating stratigraphic and
structural relationships of Morrow formation derived from 2-D
seismic
and well
data
. Extent of ethane microseeps also indicated. See Figure 5A and 5B for
locations of cross section.
