Common Risk Segment (CRS) maps demonstrate the spatial distribution of the inherent geological risk of having a “working petroleum system” within the accumulation zone of a Petroleum Play. CRS mapping is a technique, commonly used by oil companies, to evaluate the petroleum potential of a sedimentary basin.
Common Risk Segment (CRS) maps demonstrate the spatial distribution of the inherent geological risk of having a “working petroleum system” within the accumulation zone of a Petroleum Play. CRS mapping is a technique, commonly used by oil companies, to evaluate the petroleum potential of a sedimentary basin. It is in fact a new business development tool helping exploration ventures to delineate areas (Segments) of different perspectives and homogenous geological risk profiles. The methodology serves as the basis of exploration strategy elaboration.
The geological risk of a Play is controlled by the “fairways” of hydrocarbon generation, migration and entrapment. The underlying Play Fairway Analyses includes a variety of petroleum geoscience evaluations such as source rock extension, quality and maturity; secondary migration modelling; reservoir, seal and trap development. Evaluation results integrated with hydrocarbon audit and post-mortem analyses of discovery and dry wells of the play, respectively, are demonstrated in Play Fairway Maps.
The VG-talk leads students through the process of Play definition, mapping of the Gross Depositional Environment (GDE), Play Fairway Analyses (PFA) and Common Risk Segment Mapping (CRSM).
