 Data Analysis - Case Study 2
Red River County, Texas, USA.
Stratigraphic trap: Delineation of an oil-bearing reservoir
Geology
- Braided Valley Fill
- Target: Upper Jurassic Louark age alluvial fan – 5800 feet
- 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!
