Because of complexities associated with the original conditions of deposition, enhanced by subsequent diagenesis, carbonate reservoirs usually are characterized by extreme heterogeneities of porosity and permeability. Efficient reservoir-management plans require detailed, integrated geologic-engineering studies which can be used to develop reservoir-engineering numeric models. Continual monitoring of pool performance is essential to insure that the geologic model is valid. The Judy Creek and Golden Spike Devonian reef pools illustrate how the internal reservoir geometry can affect performance. At Judy Creek, a peripheral waterflood initiated in 1962 was altered to include a pattern flood in 1974 after extreme pressure gradients and geologic reservoir description indicated permeability barriers in the reef interior. At Golden Spike a miscible flood was in operation from 1964 to 1975. This now has been terminated, as recent performance analysis indicates that numerous barriers to vertical flow in the reef interior have resulted in bypassing of oil and loss of miscible-flood benefits.
