Abstract
A method includes receiving seismic data related to a subterranean formation. The method also includes receiving a selection of a property of the subterranean formation that is permitted to vary during a simulation of a model of the subterranean formation. The method also includes simulating fluid flow in the model of the subterranean formation based at least partially on the seismic data, and the selected property. The method also includes generating an updated model based at least partially upon a result of simulating the fluid flow in the model.
Claims20
A method, comprising:
- receiving seismic data related to a subterranean formation;
- receiving a selection of a property of the subterranean formation that is permitted to vary during a simulation of a model of the subterranean formation;
- simulating fluid flow in the model of the subterranean formation based at least partially on the seismic data, and the selected property;
- and
- generating an updated model based at least partially upon a result of simulating the fluid flow in the model.
A computing system, comprising:
- a simulator configured to:
- receive seismic data related to a subterranean formation;
- receive a selection of a property of the subterranean formation;
- and
- run a simulation of a model of the subterranean formation based at least partially upon the seismic data and the selected property, wherein the selected property is permitted to vary during the simulation, wherein the selected property is related to rock, fluid, or both in the subterranean formation, wherein other properties of the subterranean formation that are not selected remain fixed during the simulation, and wherein a user has a higher confidence that the other properties that are not selected are accurate in comparison to the selected property;
- and
- a plugin configured to:
- cause the simulator to run a subsequent simulation of the model using a different selected property;
- and
- cause the simulator to produce calculations of gradients of a value of interest for the simulation and the subsequent simulation.
