Abstract
A method, apparatus, and program product model address a modeling gap existing between basin and reservoir modeling through the use of a Reservoir Fluid Geodynamics (RFG) model usable for simulations conducted at a relatively fine spatial resolution and over a geological timescale.
Claims22
A method of modeling a subsurface formation, the method comprising:
- accessing a Reservoir Fluid Geodynamics (RFG) model of the subsurface formation, wherein the RFG model is organized as a spatial array having a first spatial resolution and describing at least a portion of the subsurface formation, the RFG model including basin data generated from a basin simulation of the subsurface formation at a second spatial resolution that is coarser than the first spatial resolution;
- and
- running a computer simulation on the RFG model over a geological timescale and at the first spatial resolution using at least one processing unit.
An apparatus, comprising:
- at least one processing unit;
- and
- program code configured upon execution by the at least one processing unit to model a subsurface formation by:
- accessing a Reservoir Fluid Geodynamics (RFG) model of the subsurface formation, wherein the RFG model is organized as a spatial array having a first spatial resolution and describing at least a portion of the subsurface formation, the RFG model including basin data generated from a basin simulation of the subsurface formation at a second spatial resolution that is coarser than the first spatial resolution;
- and
- running a computer simulation on the RFG model over a geological timescale and at the first spatial resolution using at least one processing unit.
