Abstract:
Eight lines of 2-D high resolution seismic data were acquired at a proposed enhanced oil recovery site in Montague County, Texas. Areal extent of the producing field is roughly 200 acres (80 ha.), of which 35 acres (14 ha.) were selected for the experiment. The producing formation is a Pennsylvanian sand, 40 ft (12 m) thick and 1,800 ft (549 m) deep. High-frequency broadband data (50 to 175 Hz) were collected using both shallow (10 ft or 3 m deep) and subweathering explosives. Additionally, a detailed vertical seismic profile was conducted to tie sonic logs to the seismic data. Results confirmed an area of good reservoir continuity while eliminating others owing to small-scale faulting and changing sand thickness.
