| 3D Reservoir Characterization |
|
A
3D geological/reservoir model is a logical first step to any complex
oil and gas play development. The advances in reservoir characterization
technology allow integration of seismic interpretations, depositional
and structural interpretations, well data and area knowledge into
one 3D virtual model. Such a model fosters multi-discipline team
communication and allows easy creation of multiple realizations
for evaluation. This resulting high quality cohesive model reduces
dry hole risk and forms the basis for evaluating pool development
strategies, with or without reservoir simulation. The following
summarizes how a 3D model can improve your odds in your E&D
projects:
- By integrating and cross-validating data
- By evaluating and validating complex relationships of geological structures, particularly in a faulted environment, in 3D
- By improving and facilitating communications among the geo-scientists and engineers
- By facilitating quick iterative interpretations
- By improved mapping and volumetric accuracies
- By providing an easy path to reservoir simulation studies
Static
3D modelling tools have
become more sophisticated
and capable over the
last few years. In addition
to new products, some existing software has received
significant upgrades.
RPS can provide in-house
assistance in selecting
the right tool and in building detailed 3D static reservoir
models that are suited
to the Roxar IRAP RMS™, Dynamic
Graphics EarthVision™, Technoguide
Petrel, T-surf GoCAD™, and Landmark Graphics’ Stratamodel™
software.
The following table lists some of our recent experience and current projects.
