  • Located unconformably on the Paleozoic and Triassic structural front of the buried Ouachita Range
  • Oil is stratigraphically trapped

Survey Summary

  • 550 grid samples in 3 phases
  • 400 – 600 ft grid spacing
  • 11 mi2 coverage

Survey Results

  • GORE® Survey results correctly redefined field trend - Pre-survey geologic and seismic interpretation indicated the trend of deposition to be in a NW to SE direction. The GORE® Survey indicated the trend was NE to SW, which was confirmed by drilling.
  • Of the 26 wells drilled in areas identified by the GORE® Survey as high-probability for oil: 25 are/were oil wells and one is a dry well
  • Of the nine wells drilled in areas identified by the GORE® Survey as low-probability for oil: three are dry wells and six are/were oil wells
  • Overall 80% success rate!
