| description | We present the analysis of a reverse vertical seismic profile (RVSP) acquired over a
pinnacle reef in the northern Michigan reef trend. The survey exhibited two features of
note: (1) a new, strong, downhole vertical vibrator, and (2) a random distribution of
surface receiver locations.
A short sequence of processing steps followed by diffraction summation migration
provide a high-resolution image of a portion of the target reef at 4600 feet depth. The
high-resolution of the image is due largely to the downhole source, which generated a
high-powered signal at frequencies up to several hundred Hz. The source signal was
repeatable, allowing our processing scheme to recover these high frequencies.
Due to adverse conditions, a large portion of the surface spread was abandoned. The
reduced spatial coverage limits the extent of the migrated image, and therefore precludes
an evaluation of the effectiveness of the random receiver spread. However, the partial
image agrees with our previous interpretation of the reef. The high-resolution offers
new insight into the structure of the reef, although a detailed geological interpretation
is not possible due to the limited extent of the image. |
