The required slug size for a patterned hydrocarbon miscible flood in the Upper Devonian reef at Fenn-Big Valley, central Alberta, was computed on the basis of dispersion/diffusion calculations at the leading and trailing edges of the solvent slug. This sluz size included consideration of microscopic heterogeneities and a safety factor so that sufficient slug remained to ensure miscibility. This calculated slug size formed the design basis for a pilot experiment in part of the pool. After 3 years of pilot operation, sufficient performance and tracer results were available to enable a re-evaluation of the design basis. The motivation behind re-evaluation was to extend the recovery process to a much larger part of the pool. Whereas local heterogeneities and transport considerations indicated that a moderate slug size (6% HCPV) was required, regional and interwell heterogeneities, flooding patterns, and geometry of flood propagation indicated that about twice this slug size was needed. Because of this, it was concluded that the realistic design basis for a field-scale project must fully consider regional and interwell heterogeneities. This paper deals with the supporting data and procedures used in developing the revised design basis for the project.
