METHOD TO COUPLE FLUID-FLOW AND GEOMECHANICAL MODELS FOR INTEGRATED PETROLEUM SYSTEMS USING KNOWN TRIGGERING EVENTS
摘要
Coupling fluid-flow model and geomechanical model for integrated petroleum systems, in one aspect, may comprise analyzing historical data associated with a reservoir to determine one or more triggering events that trigger abrupt changes in the state of stress of the reservoir solid framework and in the pore pressure. One or more time steps are defined based on the determined triggering events. The fluid-flow model and the geomechanical model are coupled at the one or more defined time steps, e.g., one-way or two-way. Number of iterations may be calculated automatically for the two-way coupling to converge.
