The goal of this project was to characterize the Dundee reservoir of Crystal oil field using the newly drilled Tow #1-3 well data in conjunction with historical well records to evaluate heterogeneity of facies and their controls on oil production.

From the Tow# 1-3 HD-1 well, three major facies were identified in the reservoir. A non-fractured intertidal grainstone facies provides storage of fluids with its uniform permeability and excellent intercrystalline porosity. The supratidal fractured micrites and open marine fractured biomicrites are interbedded with the grainstone facies providing conduits for fluid migration between the facies. Facies are important controls on oil production in conjunction with the strong water drive of this reservoir. Pervasive fracturing and a strong water drive, produced water coning in vertical wells causing early abandonment. Horizontal drilling as a current secondary recovery technology, was demonstrated in the Tow #1-3 HD-1 as an efficient means for producing this type of reservoir, with 60,000 bbls. of water free oil produced to date. Additional oil recovery from Crystal Field could be as much as 200,000 bbls. per horizontal well. This technology can be applied to similar reservoirs throughout Michigan.
