Previous HitSeismicNext Hit Expression of Red Fork Channels in Major and Kay Counties, Oklahoma

Cliff A. Hanoch

This paper investigates the application of regional Previous HitseismicNext Hit to exploration and development of Red Fork sands of the Cherokee Group, in Major and Kay Counties, Oklahoma. A computer-aided exploration system (CAEX) was used to justify the subtle Previous HitseismicNext Hit expressions with the geological interpretation. Modeling shows that the low-velocity shales are the anomalous rock in the Cherokee package, which is most represented by siltstone and thin sands. Because the Red Fork channel sands were incised into or deposited with laterally time-equivalent siltstones, no strong reflection coefficient is associated with the top of the sands. The objective sands become a Previous HitseismicNext Hit anomaly only when they cut into and replace a low-velocity shale. This knowledge allows mapping the channel thicknes by interpreting the shale thickness from Previous HitseismicNext Hit Previous HitdataNext Hit. A group shoot line in Major County, Oklahoma, has been tied to the geologic control, and the channel thicknesses have been interpreted assuming a detectable vertical resolution of 10 ft.

A personal computer-based geophysical work station is used to construct velocity logs representative of the geology to produce forward-modeled synthetic Previous HitseismicNext Hit sections, and to Previous HitdisplayNext Hit, in color, the Previous HitseismicNext Hit trace attributes. These synthetic sections are used as tools to compare with and interpret the Previous HitseismicNext Hit line and to evaluate the interpretive value of lower cost, lesser quality Previous HitdataNext Hit versus reprocessing or new Previous HitdataTop acquisition.
