FIGURE 18. Fence diagram of the VLA1131 well
, showing the
structureal closure, faults, and unconfomity at the top of the
C-5 horizon. West-east inline 28 and north-south crossline 605
make up the two sides of the fence diagram. See Figure 16 for
location of seismic lines. The high amplitude seismic events
outline the C-4 to C-6 reservoirs.
FIGURE 20. Synthetic seismogram, gamma ray log
, and west-east
inline 28, showing the structure and
log
character for the VLA
1131 discovery
well
and the CLA 1147 twin
well
. THis display
shows, from left to right: sonic
log
, reflectivity, synthetic
seismogram, seismic reference trace (trace at
well
location), and
an interpreted section of inline 28 from the 3-D seismic survey
with gamma ray
log
overlain at the
well
location. Other
abbreviations: BLR = basal La Rosa Formation, ER-EO = Eocene
Unconformity, and CDP = common depth point.
