The following case studies review the benefits of using GORE™ Surveys in frontier block evaluation, prospect evaluation, and field development through difficult geologic sequences containing volcanics and salt and climates including permafrost, desert, forest, and jungle. They include structural, stratagraphic, and combination traps of petroleum phases including dry gas, wet gas, condensate, and oil.
-
Algeria, Berkine Basin
- Structural trap: Delineating oil reservoirs
-
Arctic North America
- Permafrost – Arctic North America
-
Bolivia, Sub-Andean Thrust Belt
- Structural highs: Detecting potential charge
-
Custer/Roger Mills Counties, Oklahoma, USA
- Thirty wells drilled in conjunction with the information provided by the GORE™ Survey. Client’s net sand thickness isopach based on wells drilled post-survey closely matches the GORE™ Survey result.
-
Development - Lithuania
- The survey area is located in the Baltic Syneclise petroleum province, Lithuania. Target was an on-shore marine Cambrian sandstone. Producing horizon is about 2,000 m deep. Reservoir traps are a result of Caledonian tectonism. Goal of the survey was to determine the field limits and identify reservoir sweet spots.
-
Dry Gas Exploration - Romania
- ROMGAZ, the national gas company of Romania, and W. L. Gore & Associates, Inc. conducted a GORE™ Survey on two exploration prospects in Romania. The primary goal was to reduce exploration risk and increase chances of finding natural gas. The natural gas in these prospects was known to be "dry", greater than 99% methane by volume, and provided a unique challenge for the survey.
-
Egypt, Onshore
- GORE™ Survey was able to detect hydrocarbon microseepage through thick salt sequences. The next well drilled on GORE™ Survey data
(FH85-8) produced 800 bopd; the highest production rate in the region.
-
Frontier - Chile
- No geological information was available at the time of the survey.
The potential for encountering hydrocarbon-bearing zones was
unknown. The main objective of the survey was to locate and
evaluate the potential of finding hydrocarbons indicative of deeper
fossil fuel deposits, and therefore, focus further exploration efforts.

-
Multi-Layer Gas Exploration – Texas
- A surface geochemical survey was conducted on a natural gas exploration prospect in Texas, USA. The exploration target was a structure, defined by seismic data and located at depths of 3,300 meters, thought to contain Wilcox gas. Producing oil and gas wells exist in the area along a major upthrown growth fault. Overlying the target structure were shallow oil and gas producing zones.
-
Northern Russia, West Siberian Basin
- GORE™ Survey indicated several large geochemical features for both gas-condensate and oil. The observed geochemical features correspond perfectly with the known seismic situation. There are similarities between both geochemical models, indicating that the hydrocarbons are chemically related.
-
Papua New Guinea, Mogulu Structure
- Survey was able to detect hydrocarbon microseepage through thick aquifers and thick volcanic sequences. It mapped out fault blocks, showing that some fault blocks have more potential than others
-
Red River Country, Texas, USA
- 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.
