Abstract: The invention relates to a system for modeling an oilfield, which has process facilities and wellsite operatively connected, each wellsite having a wellbore penetrating a subterranean formation for extracting fluid from an underground reservoir. The system includes multiple wellsite simulators, each modeling a portion of the wellsite, at least one non-wellsite simulator, each modeling a portion of a non-wellsite region of the oilfield; and at least one coupling positioned among the wellsite simulators and the non-wellsite simulator. The coupling selectively links the wellsite simulators and the non-wellsite simulator according to a pre-defined configuration for selective communication.

Abstract: An integrated model based on plural underlying models relating to corresponding aspects of subterranean formation development is provided. A utility is created to perform a function using the integrated model. The utility is assigned to execute in a distributed computing system having a plurality of computer node. Computations performed by the utility are distributed across the plurality of computer nodes, where the computations are related to simulations using the integrated model.

Abstract: A method for performing operations of an oilfield is described. The method involves selectively coupling oilfield simulators according to a predefined configuration, each oilfield simulator modeling at least a portion of the oilfield, a first oilfield simulator receives an oilfield control parameter as an input, identifying an uncertainty parameter associated with probable values each corresponding to a weighted probability, a second oilfield simulator receives the uncertainty parameter as an input, modeling the operations of the oilfield to generate an estimated performance by selectively communicating between the oilfield simulators, the operations of the oilfield are modeled with a predetermined value of the oilfield control parameter and at least one of the probable values of the uncertainty parameter; and identifying an optimal value of the oilfield control parameter based on the estimated performance.
