GeoMark’s success came from hard work, dedication, and laser focus over the years to not only deliver on client requests, but to exceed their expectations. From Day 1, our approach has been to collect a very large suite of produced and seep oil samples that give our researchers and customers a complete look at all the petroleum systems generating hydrocarbon in the basin of interest. We then analyze these oil samples, using a standardized set of detailed oil analysis techniques (biomarkers and stable isotopes). The data are subjected to Principal Component and Hieratical Custer Analysis to determine the number of petroleum systems in a region, and the age and depositional environment of the generating systems. This information is combined with the regional geology to build a petroleum system model of the basin. Ultimately, the resulting reports are licensed to participating companies. Since GeoMark retains ownership of both the analytical results and the physical samples, we have been able to build the largest collection of petroleum reservoir fluid and source rock data from reservoirs around the world.
