Exploration
The exploration phase stretches from initial country and basin analysis, through play identification and lead generation, to prospect analysis and risking. Our services, technologies and products are tailored to meet the needs of E&P companies worldwide. Building on in-depth regional geological knowledge and familiarity with the PGS worldwide data library, our workflows provide a unique understanding of prospectivity and reduce exploration risk.
PGS provides advice and support through both technical and managerial aspects of exploration activities. The following table provides a summary of our geological, geophysical and data management services:

Regional, Basin & Play Analysis
Deepwater Miocene channel systems within the Congo MegaSurvey.PGS’ clients benefit from proprietary services based on both off-the-shelf products and tailored workflows. With access to our large library of broadband and conventional seismic data, PGS interpretation teams have acquired a comprehensive understanding of the offshore oil basins of the world that we draw upon in our regional datasets, studies and fully integrated interpretation services. We can readily apply this knowledge to our client’s proprietary data to provide insights into their acreage. In addition to our technical services, a number of in-house regional and basin-scale products are offered off-the-shelf, or serve as the basis for proprietary exploration projects.
Our regional knowledge is derived from information on plate tectonics, gravity and magnetic data, as well as regional geology. Combining analysis of the structure, source and seal characteristics of a reservoir as well as the distribution, we are able to evaluate the potential of a basin. Sedimentological environment studies, provenance area assessment and hydrocarbon generation potential are also examined to fully evaluate a prospect and to minimize risk in the exploration processes.
Leads & Prospect Analysis
PGS GeoStreamer® pre-stack seismic attributes for lead and prospect analysis over the HVG2013 dataset, Halten Terrace.
We have an extensive track record in prospectivity analysis on both the PGS data library and from client data. Our lead and prospect scale studies provide rigorous assessment of potential hydrocarbon volumes and their associated risks.
Resource Evaluation & Risking
Hydrocarbon probability attributes shown for GRVLIN2012 dataset from the Viking Graben.
PGS experts provide independent resource evaluations and risking from semi-regional to block level. PGS supports clients in the quantification of resources by integrating seismic interpretation, attribute analysis, geological and well data. This enables us to correctly estimate resources and the exploration potential and risks (trap, source, seal and reservoir), thus minimizing risk for exploration companies. Resource quantification and risking follows well known and respected industry-led guidelines.
