### Seismic Modeling in the Minneola Complex, part 7 of 10

## Multi-Well Model Interpretation

The multi-well model uses the Cannon, Statton, Rooney, and Shumate
wells (Fig. 3) to build a pseudo-cross
section which should show the change in seismic signature as a
sandstone thickens in a relatively thin channel interval, as a
channel interval thickens while keeping the same sandstone
thickness, and as a moderately thick sandstone changes laterally
into a shale in a relatively thick channel interval (Fig. 7a).
Unlike the single well model, all of the wells are different and
none of them are modified. Correlated tops are the same as the
single well model, but include a base of Morrow sand horizon (BMSD)
which extends to the Shumate well for correlation consistency even
though the well contains no upper Morrow sandstone (the phantom
correlation does not affect the log values at the well). The model
extends above the Marmaton but is not shown to focus on the area of
interest.
**Figure 7a**--Multi-well model cross section. Sonic
curves are red and bulk density curves are blue. Vertical scale in
feet below sea level. Horizon (tops) abbreviations are Marmaton
(MRMT), Cherokee (CHRK), Atoka (ATOK), Morrow (MRRW), base of upper
Morrow sandstone (BMSD), and Mississippian (MISS).

**Figure 7b**--Interpolated single well acoustic
impedance model. Reds represent limestones, sandstones, and higher
velocity shales. Yellows and oranges represent lower velocity
shales. Vertical scale in seconds of two-way travel time from the
top of the model and is approximately twice that of the seismic
models. A black and white
verion of this plot is available.

**Figure 7c**--Same as Figure 7b but with a vertical
scale approximately the same as the seismic models.
A black and white verion of this plot is
available.

The log interpolation model of this cross section is shown as a
vertically expanded version in Figure 7b and at the same scale as
the synthetic seismic section in Figure 7c. The log interpolation
model is generated and displayed in the same way as the interpolation
model for the single well case. The color representation is also
the same. One difference, however, is that this log interpolation
model is flattened along the top of the Morrow to simplify seismic
interpretation of the Morrow-Mississippian interval.
