Access data on over 490 wells. We have regionally consistent well and rock physics models for Europe, the Gulf of Mexico, and parts of West Africa. License from one to several hundred wells in our interactive rockAVO modeling software to make your assessment of hydrocarbon potential easy.
PGS has added well data, including rock physics models, interactive seismic AVO modeling capabilities, and data atlases to its MultiClient data library, allowing you to integrate seismic with well data. This means you can now calibrate GeoStreamer and other seismic data with conditioned well data and known production scenarios.
E&P companies can now access a homogeneous database of interpreted well logs, making it possible to analyze the seismic AVO signature based on different fluid and matrix property perturbations.
Adding interactive rock physics modeling tools to a seismic analysis will further improve derisking and make it easier for exploration teams to identify play analogs for prospect screening and analysis. Production teams can use the tools to interrogate nearfield opportunities.

Get Closer to the Reservoir with Rock Physics Integration
Rock physics is the link between the seismic response and geological properties. It explains how rock properties (like clay content, porosity, and fluid-fill) influence elastic properties (such as velocity and Poisson’s ratio), and therefore the prestack seismic amplitude response at the well location.
The integration of well-based rock physics data in the PGS data library means that the interactive rock physics atlas browser rockAVO is now available as a MultiClient product. These rock physics atlases are a good fit with the PGS seismic data library, especially in the US and Europe. Well data is currently available for the Gulf of Mexico, the Barents Sea, the Norwegian Sea, the North Sea, the UK Central Graben, the Nigeria São Tomé JDZ.
The combination of GeoStreamer data and imaging technology, reprocessed broadband seismic data, and rockAVO rock physics tools and atlases offer significant benefits. Integrating seismic with well data can, for example, demonstrate AVO compliance.
Unlocking Reservoir Properties
Rock physics properties vary from basin to basin, and from stratigraphic interval to interval. For each, a separate model or rock physics template is required that relates the seismic response to earth properties.
PGS has now added the geological part that comes from the well data to its comprehensive seismic data library. The rockAVO tool is proven to deliver fully interactive, well-by-well rock physics AVO modeling. It transforms a static hardcopy study into a fully dynamic live report, making it accessible to non-rock physics experts.
Well Atlases with Rock Physics Models
Regional rock physics atlases are available for Europe, the US Gulf of Mexico, and various countries in West Africa, including the Nigeria São Tomé JDZ. More are underway.
Each well in these atlases has been conditioned and interpreted consistently, to a high technical standard. Deliverables include the raw and conditioned log data, the petrophysical interpretation, and the rock physics modeled elastic logs. TChahe results are delivered within rockAVO. See below for more details on each of the atlases.
At the exploration stage, combining regional rock physics atlases with seismic data library coverage will permit fuller and faster calibration of zones of interest and analog screening.
Calibrate | Well Data to 4D Seismic
Combining 4D well modeling with 4D seismic offers further proof of the 4D AVO compliance and imaging integrity of PGS seismic data.
4D synthetic AVO modeling can be integrated with measured seismic gathers, using the rockAVO interactive software. This means PGS can now deliver enhanced 4D feasibility studies and scenario modeling of reservoir characteristics, like saturation and pressure changes.
Quantitative Interpretation Advantage
The objective of QI is to derive elastic seismic attributes within their proper geological context. Using rock-physics driven QI techniques combining rockAVO, prestack AVO compliant seismic data, and additional post-seismic inversion technologies, PGS clients can now better predict rock and fluid type accurately during reservoir review and prospect analysis.
