Exploration, production and average evaluation:
- Review and validating existing data
(Geophysical, geological, geochemical, engineering and production data)
- Geological interpretation
- Structural interpretation and fault modeling
Fault models and associated input data that exist in the time domain can be depth converted based on a variety of velocity models.
Along with depth converted horizon data, fault surfaces and -lines are used as input to the 3D modelling grid process. Two different methods are available for implementing faults in the 3D grid.
The conventional method for implementing faults generates grid splits and grid pillars parallel to the fault surface. A more flexible method incorporates faults through stair-stepping pillars.
This approach enables the inclusion of faults that are converging and truncating within the reservoir (Y-fault geometries) as well as listric faults that dies out within the reservoir. Both grid geometries can be exported and used as input to a flow simulator.
