  • Abstract

Coupled flow- and rock mechanics simulations are necessary to achieve sufficient understanding and reliable production forecasts in many reservoirs, especially those containing weak or moderate strength rock. Unfortunately these runs are in general significantly more demanding with respect to computing times than stand-alone flow simulations. A scheme is presented whereby the number of needed rock mechanics simulations in such a setting can be reduced to a minimum. The scheme is based on constructing optimal input for flow simulations from a few rock mechanics runs. Results obtained with the scheme are at least as accurate as traditional coupled runs, but computations are considerably faster, often as much as two orders of magnitude.
