Bolivia, Sub-Andean Thrust Belt
Geology:
- Highly faulted anticlines
- Target: Gas in the Devonian Huamampampa Fm. at a depth of 3500 to 5000 m
- Surface terrain has extremely rugged, steep rocky slopes with thick vegetation
 
Survey Summary
- W/E transects across anticlines
- 600 km2 coverage
- 1000 m sample spacing
Survey Results
- GORE™ Survey accurately predicted outcome of five out of five post-survey wells
- Client could have saved $60 million on dry hole expenses (each well cost ~$15 million)
