Abstract: A method of solving a optimization problem is described. The method includes creating an initial model having a plurality of wells, each well being associated with a parameter and dividing the well field into first and second regions, the first region including a first subset of the plurality of wells and the second region including a second subset of the plurality of wells. The method also includes solving for the parameters associated with the wells in the first subset to get a first set of values while holding constant the parameters associated with the wells in the second subset, setting the parameters associated with the wells in the first subset to the first set of values, and solving for the parameters associated with the wells in the second subset to get a second set of values while holding constant the parameters associated with the wells in the first subset.

Abstract: A computer system records a plurality of cases. Each case is used with a software system. The version of the software system is the same for each case. Each case includes a set of input data. Each case includes an identification of a parent case from which input data in the case was copied unless the case is an original case. The identification of the parent case creates a parent/child relationship between the case and the parent case. The computer system creates a hierarchy of the parent/child relationships among the plurality of cases. The computer system displays a subset of the plurality of cases in response to a search of the plurality of cases. A smaller subset of the plurality of cases is selected as a chosen model for an environment in which an activity is to be performed.

Abstract: A system and method of automatic local grid refinements in reservoir simulation systems is described. In one aspect of the disclosure, a method is directed to a computer-implemented method of modeling a formation. The method includes applying a coarse grid to a geologic formation of interest, the coarse grid having a plurality of coarse grid blocks and identifying a structure of interest disposed in the formation. Further, the method includes determining a fine grid zone around the structure based upon a time period for flow simulation of the geologic formation and a geologic characteristic of the geologic formation in a local region adjacent the structure and applying a fine grid to the coarse grid blocks encompassed by the fine grid zone.
