Modeling and Interpretation
Create the most reliable 3D models of the earth’s subsurface
In the past, modeling limitations made maintaining synchronization between the model and the current interpretation difficult. Users lacked the time and expertise needed to efficiently perform these workflows. AspenTech Subsurface Science & Engineering (SSE) has succeeded in streamlining this process while preserving the complexity and fidelity of the subsurface interpretation. This breakthrough provides geoscientists with the full range of benefits to be gained by modeling while interpreting.
The result of an interpretation, whether automatic or manual, is a sparse representation of a series of horizon and faults. These representations are then transformed into a structural model where faults form a consistent fault network and horizons are correctly faulted. By using all of the data, avoiding simplifications, and working within a 3D Common Earth Model, the AspenTech SSE subsurface modeling solution ensures accurate interpretations and therefore more accurate geological or reservoir models.
The structure of a field is often one of the most critical components of the reservoir model and can account for the greatest uncertainty in terms of in-place reserves. Combine this with the time it can take to build accurate models and the limitations in many approaches, and you have a substantial drain on the asset team and a significant source of uncertainty in the field model. AspenTech SSE Structural Modeling solutions provide a powerful productivity and accuracy enhancement solution for reservoir management and field development planning. These help users achieve maximum reservoir performance and make more reliable decisions.
Model-driven interpretation provides solutions to the common industry challenges of geologic risk assessment and productivity by providing tools to capture and quantify fault and horizon uncertainties in interpretation and integrate these measurements into modeling workflows. Multiple surfaces can be created from uncertainty estimation, giving the user the flexibility to choose the right one.
Model-driven Interpretation Benefits
- Interpret areas where seismic data is of poor quality using manual picking. Manual picking provides better results by using the interpreter's logic to decide where the reflector might be.
- Rapidly create a fully sealed structural model, whatever the geologic complexity, in a user-friendly, highly advanced computing environment.
- The ability to visualize the automatically depth converted model while interpreting enhances interpreter confidence.
Global Interpretation: Automated seismic interpretation and model building using all of the seismic data.
AspenTech SSE's global interpretation software solution combines interpretation and modeling in a single integrated and iterative workflow. Easy and intuitive, it enables users to interpret faults, automatically pick all seismic reflectors, and with one click of a button, create a 3D model using all available data. In this unique workflow, based on the patented, paleo-geographic UVT Transform™, there is no need to simplify the complexity of the structure. The 3D seismic flattened view, where all horizons are flat and unfaulted, provides a way to quickly check if the horizon interpretation matches the seismic events. The final, fully unified model is complete and perfectly sealed, and ready for use in velocity modeling, inversion, geological modeling, reservoir modeling, and geomechanics.
