RokDoc -Â Reservoir Characterization & Insightful Seismic Inversion Module Software
Effective seismic reservoir characterization requires a solid understanding of the rock physics and the appropriate seismic data conditioning, seismic inversion, and seismic reservoir characterisation technology. These tools and workflows must be fast, interactive, and deployable within pragmatic timeframes. The RokDoc Reservoir Characterization Module provides this and more.
Leverage the knowledge from well-based rock physics analyses to make more robust predictions of rock properties and subsurface architecture from seismic. Capture and analyse both data and geological uncertainty in the estimates.
Get access to fast, recipe-based seismic data conditioning and seismic inversion workflows. Chained recipes make parameter testing a breeze, adjust any parameter in the workflow from data conditioning, to inversion, to facies classification and immediately see the impact on the final product. Only generate the volumes on disk that you need.
A full understanding of the impact of production on seismic response requires integration of engineering, geological and geophysical data in a single shared Earth model. Only by making this connection can we extract the most value from time-lapse seismic. The Reservoir Monitoring add-on provides a framework for modelling the effects of production and provides a space to estimate changes in saturation and pressure from changes in seismic response over time.
Challenge: In this frontier basin, sparse well control coupled with complex seismic responses from a mixed clastic-carbonate settings means that predicting reservoir, and pay, presence is highly uncertain and subsequently well placement is high risk.
Solution: A reservoir characterization tool that predicts facies directly from seismic data based on, and consistent with, a robust understanding of regional rock physics trends per facies. A method of capturing the geological uncertainty in the inversion scheme, and the ability to investigate and understand that uncertainty. A truly 3D inversion where the mixed discrete/continuous nature of the inverse problem is captured allowing for the prediction of precise facies transitions.
Results: Accurate pre-drill prediction of facies layering and geometry, hydrocarbon contacts and hydrocarbon column. Elastic impedances that are consistent with regional rock physics trends and the investigation of geological uncertainty. Pre-drill prediction of gas column thickness within 4ft of that encountered by the post-inversion well.
A flexible and powerful set of seismic data conditioning and seismic inversion tools. Implemented as coupled recipes, the conditioning and inversion tools can be linked to form one interactive chain between input seismic and final inversion products. In addition, a range of QC products and links back to the well control are provided, so that you can run seismic inversion both quickly and with confidence.
Condition seismic data and run seismic inversions with confidence
Both seismic data conditioning and seismic inversion require careful parameterisation and testing to achieve the best results for the dataset you have. RokDoc therefore takes an interactive chained recipe-based approach, allowing rapid parameter testing, and real-time insight into the impact on the final result.
