Patent ID: 8249844

Claim:
A method for optimizing an aspect of a well comprising: identifying a plurality of failure modes for a well, at least one of which is associated with a selected aspect of performance for the well; obtaining at least two technical limits associated with each of the identified plurality of failure modes, wherein obtaining the at least two technical limits comprises using a processor to perform at least one of: (i) generating a response surface to at least one of the plurality of failure modes using a parametric study that incorporates an experimental design approach, to obtain at least one of a well operability limit, a well producibility limit, and a well injectibility limit, in combination with generating a coupled physics technical limit derived from a first failure mode and a second failure mode of the plurality of failure modes; and (ii) using a previously generated response surface to at least one of the plurality of failure modes, wherein the previously generated response surface is based on a parametric study that incorporates an experimental design approach, to obtain at least one of the well operability limit, the well producibility limit, and the well injectibility limit, in combination with generating the coupled physics technical limit derived from the first failure mode and the second failure mode; formulating an objective function for the selected aspect of well performance optimization; and solving an optimization problem using the objective function and using the at least two technical limits, to provide an optimized solution for the selected aspect of well performance.
