Basin Studies

Field Geo Services and its partners are well known to maintain the highest standards for geochemical analysis.  This applies to routine screening runs as well as the most sophisticated analysis.  A number of advanced analytical and interpretation methods have originally been developed by FGS and partners.  Our goal is to deliver quality products that provide the client with solutions to their most ambitious demands.

Example of 1-D basin model output to determine timing for hydrocarbon generation for a well on the Colorado Plateau.

Reservoir Geochemsitry

Field Geo Services and partners conduct studies of reservoir scale geochemistry on a global basis, and advocates using this technology with related disciplines.  The discipline is conveniently divided into three primary topics exploration, appraisal, and production which depend on the client defined objectives. Our projects commonly impact the needs of multiple work groups (engineering or geological), and can address goals at different spatial scales.  Reservoir geochemistry can address kilometer scale questions of faults acting as barriers vs. conduits, meter scale problems of assessing the interconnectivity of individual sand lobes in a deltaic sequence, or micron scale issues concerning the impact of solid reservoir bitumen to the economic reserve analysis.

Distribution of solid reservoir bitumen (viewed in reflected white light) can be critical to resource evaluations.


We combine off the shelf technology with expertise in developing creative solutions to provide products that reduce drilling and development expenditures, increase hydrocarbon recovery efficiency, and increase confidence in the decision making process.

We emphasize attention to detail, multi-dimensional visualization, mass balance, and rapid communication of results.
