Claim One:
1. A method for enhancing a production history matching process, the method comprising: obtaining production data and an initial subsurface model; determining an experimental design including one or more model parameter sets; for each of the model parameter sets in the experimental design: calculating a value for a static measurement, wherein the static measurement comprises a measurement of connectivity in a geologic model between two wells in the subsurface model, two compartments in the subsurface model or between two locations in the subsurface model identified as well locations, wherein the static measurement is a property measurement associated with a subsurface region, and wherein the subsurface region includes one or more of structure components, reservoir architecture components, rock type components, and petrophysics components, wherein the connectivity includes transmissibility that is the volumetric flow rate between two points at unit viscosity for a given pressure drop; performing, using a computer, at least one flow simulation to generate results; and comparing the generated results with the production data via an objective function to provide an objective function value; determining relationships between the objective function values for the model parameter sets in the experimental design and the static measurements; determining a screening filter based at least in part on relationships between the static measurements and the objective function values for the model parameter sets in the experimental design; and for subsequent model parameter sets: calculating a static measurement associated with each of the subsequent model parameter sets; performing a history match process for each of the subsequent model parameter sets that satisfies the screening filter.
