This paper describes the development of a discrete feature network (DFN) model for the South Oregon Basin field in the Big Horn Basin of Wyoming. This DFN model is being developed to support well placement and gel treatment in order to recover previously bypassed oil in this highly heterogeneous, structurally controlled carbonate reservoir.

The DFN model developed in this paper is based on data from outcrop studies, fracture and lithologic data from wells and lineament maps from 3D seismic. The model is calibrated against tracer test results.
