Getech’s team of petroleum geologists systematically investigate the petroleum systems of the world through an integrated workflow, which can be applied on both a regional and block-scale. These are provided to explorationists as multi-client Regional Reports and proprietary Commissions.
The advantage of the Getech workflow is that it brings together and analyses the full range of expertise, data and knowledge at Getech in order to better understand the petroleum geology. This starts with the role of the tectonic and structural framework on crustal architecture and basin evolution; this in turn affects landscape evolution, and the consequent drainage network evolution, and source to sink relationships. Through this we can gain insights into the facies character and distribution in downstream depositional settings. Palaeoclimatology is an important influence on these processes, and by using Getech’s extensive Earth System Modelling portfolio and expertise we have developed a unique prediction tool for frontier areas where data is scarce.
Combining these methodologies with observational data from seismic and wells, our petroleum geologists can then focus on the distribution of source rocks, reservoirs and seals, and the potential quality of each element in order to make an assessment of the overall hydrocarbon prospectivity. Geological summaries and petroleum system evaluations are completed for each region, including traditional chronostratigraphic charts, petroleum systems events charts and play cartoons.
Increasingly this information is provided through ArcGIS™ in order to give the user more staightforward digital access to all available information.
A further part of the workflow includes an extensive analysis of the petroleum geochemistry. This includes oil-rock correlations, 1D modelling experiments, and the mapping and investigation of the spatial relationships of maturity and expulsion.
