Patent ID: 8306801

Claim:
One or more computer-readable storage media comprising computer-executable instructions to instruct a computing system to: receive simulation results for a simulation of future behavior of a reservoir that includes a material production well and a fluid injection site, the simulation results being from a history matched reservoir simulator that implements a numerical technique that discretizes the reservoir into blocks and parameters for the blocks wherein the numerical technique models the reservoir, the material production well and the fluid injection site; define a model sensor as a line, a surface or a volume with respect to one or more of the blocks and associated parameters, the modeled sensor located a distance from the modeled material production well and between the modeled material production well and the modeled fluid injection site; determine fluid saturation at the modeled sensor based at least in part on the simulation results for the associated parameters of the modeled sensor; perform a surveillance workflow analysis for the reservoir based at least in part on the determined fluid saturation and field data for the reservoir; and issue a notification if the fluid saturation at the modeled sensor exceeds a fluid saturation limit.
