Embodiment Construction

[0037] Exemplary embodiments of the present invention enable decisions to be made regarding reservoir development planning where details of uncertain parameters remain unknown. Such uncertainties can be directly considered within the optimization model, which can be a robust optimization model. In an exemplary embodiment, a robust optimization model systematically handles all uncertain data. Such a paradigm allows for the generation of flexible or robust optimization solutions that maintain the feasibility of covering the uncertainty space, and such a paradigm allows for a trade-off between optimality and randomness or uncertainty in the input data Make trade-offs.

[0038] In certain exemplary embodiments, robust optimization provides a method for reservoir development planning and efficiently handles uncertainty. In some embodiments, optimization may be similar to a recourse model for random programming. Penalty functions in objects, however, can supersede the feasibility...

Abstract

A robust optimization-based decision support tool for reservoir development planning can comprise a source of input data, an optimization model, a high fidelity model for simulating the reservoir, and one or more solution routines interfacing with the optimization model. The optimization model can consider unknown parameters having uncertainties directly within the optimization model. The model can systematically address uncertain data, for example, comprehensively or even taking all uncertain data into account. Accordingly, the optimization model can provide flexible or robust optimization solutions that remain feasible over an uncertainty space. Once the reservoir model is optimized, final development plans may be generated.
