GEOCHEMISTRY
A unique technique that is very complementary with Seismic and it is a great tool that helps to minimize the risk to find oil and gas.
The Amplified Geochemical Imaging method is an advanced surface geochemical prospecting tool capable of detecting and quantifying many organic compounds up through phytane. This geochemical sampling system employs the GORE Module (patented passive soil vapor sampling device), state-of-the-art chemical analysis and sophisticated statistical geochemical pattern recognition from over twenty years of experience in soil gas geochemical exploration and analytical chemistry. It is capable of differentiating accumulated reservoir hydrocarbons from background hydrocarbons such as those emanating from source rock or residual migrated oil.
- Frontier - to determine hydrocarbon potential over large previously unexplored areas;
- Exploration - focus geophysical efforts, prioritize leads or investigate stratigraphic traps;
- Development - define the areal extent of producing fields and locate potential areas for secondary recovery. Prudent use and integration of the geochemical results can have significant benefits to the success of an exploration program, resulting in fewer dry holes.
AGI’s unique and highly sensitive passive diffusion modules can detect these compounds in soil gas, air and water, at levels in the sub part per billion range. Gore Surveys technology for Exploration has been used effectively in over 130 basins in more than 56 countries in all terrains including desert, jungle, plain, tundra and off-shore.
GEOLOGY
Structural Seismic Interpretation
In structural seismic interpretation, seismic data collected from the field is used to build structural, three-dimensional maps of the subsurface geology.
These three-dimensional maps of the well-site geology can be used to display a visual representation of the subsurface and distinguish separations between geoclines to help identify the most optimal drilling location.
Lithologic Seismic Interpretation
Unlike structural and stratigraphic interpretations, lithologic seismic interpretation focuses on changes in porosity, fracture intensity and lithology from the collected seismic data. Lithologic seismic interpretation can provide valuable information in the form of direct hydrocarbon indicators, which could potentially identify the presence of hydrocarbons in the region.
Stratigraphic Seismic Interpretation
Stratigraphic seismic interpretations help geologists develop chronostratigraphic frameworks based on the patterns of reflections in the seismic data. The boundaries between subsurface regions are identified on the basis of reflection termination patterns and the continuity of the reflections.
ENVIRONMENTAL
Natural Source Zone Depletion (NSZD) describes processes that result in the transformation of LNAPL contaminants into inorganic dead-end products (e.g., carbon dioxide, or CO₂). These transformation processes are called mineralization.
Most mineralization processes are driven by microbes and result in the oxidation of petroleum compounds into CO₂. This oxidation requires external electron acceptors such as oxygen, which drives aerobic biodegradation. Under anaerobic conditions, possible electron acceptors are sulfate, nitrate, and metal oxides.
Recent and ongoing research suggests that LNAPL NSZD rates can be significant. LNAPL degradation rates at hydrocarbon spill sites range from hundreds to thousands of gallons per acre per year; these rates are similar to those achieved by active remediation efforts (such as hydraulic recovery). Therefore, NSZD should be considered a viable remedial option and/or a benchmark for other remediation efforts.
