Steamflood time-slice movie of two 3-D migrated seismic
data cubes taken before and after 3 months of steam injection.
The left panel shows time slices of increasing pseudodepth
in the 3-D migrated survey taken before steam injection.
The right panel shows the same time slices as the
left panel, except of migrated data recorded after 3 months
of steam injection. The time of the slice is annotated in
the lower left corner. Note that the surveys are fairly
"repeatable" above the reservoir zone, and that the well
location and steam disk can be seen in the center of the
right panel at and below reservoir depth (about 0.160 seconds).
A 3-D migrated seismic data cube over a steam injection
pattern.
The top panel is a time slice at the depth of steam
injection, the front panel is a cross-section through
the center of the pattern. The steam zone is the
red disk in the center of the time slice with a diameter of
about 50m after 3 months of steam injection. The vertical
stripe in the center of the cross-section is the heated
borehole casing of the steam injection well, imaged with
an amazing 2-pixel resolution.
The dark "channel meanders" in the time slice which flow
from left to right are related to an exciting
seismic/fluid-flow phenomenon that may prove to be
a major research breakthrough. Stay tuned for upcoming
published results! :')
