A Review of Selected Michigan Niagaran Reef Waterfloods to Estimate the Fractional Flow Behavior During Flooding and Hysteresis Effects After Flooding

Brock, Timothy J.

Michigan has many oil reservoirs that have been found since the 1960's in the Silurian-aged Niagaran Series. A number of these reservoirs were waterflooded between the 1970's and 1990's. By using some of the reservoir properties submitted for the waterflood hearings and production data submitted after the commencement of the project, it is possible to estimate the fractional flow behavior of the fields on a reservoir basis. Additionally, some of the reservoirs were produced after flooding with water diverted to a disposal well (not in the reef reservoir). This should produce data that can be used to examine the hysteresis behavior of the reservoirs. This presentation will consider a sampling of reservoirs in the Northern and Southern Niagaran Reef Trends of Michigan and present the results obtained by analyzing the available data.
