Return of the Dundee: A Core Workshop

Lessons learned from research and past exploration

March 16, 2017

At the Michigan Geological Repository for Research and Education

5272 W. Michigan Avenue, Kalamazoo, MI 49006

8:30-9:30—Welcome and continental breakfast

9:30-10:15—William B. Harrison, MGRRE Director, will discuss the regional geology of the Dundee and Rogers City formations in the Michigan Basin and the stratigraphic sequence patterns seen throughout the State. He will also review production histories for selected fields and reservoir production trends for the different types of Dundee and Rogers City reservoirs. Decline curves for selected reservoirs will also be presented. Bill Harrison received his PhD from the University of Cincinnati in 1974, founded the MGRRE/Core Lab in 1982, and has authored dozens of papers on Michigan geology.

10:15-10:55 Break and core examination

10:55-11:45— Peter Voice, Faculty Teaching Specialist, will review facies types, stacking patterns and regional distribution of carbonate facies in the Dundee-Rogers City interval. These facies types will be interpreted as a depositional model. Modern depositional environment analogs will be used to infer controls on deposition. Discussion will focus on the control that primary depositional fabrics exert on fluid pathways, templating of diagenetic alterations, and development of reservoir quality in the Dundee-Rogers City Interval. Peter received his PhD from Virginia Tech in 2010 and has worked on Michigan Basin projects for ten years.

11:45-12:00—John Fowler Receives MGRRE’s Lifetime Achievement Award

12:00-1:00—Lunch and core examination

1:00-1:50 Steve Kaczmarek,Assistant Professorof Geosciences, will reviewthe various hydrogeochemicalmodels ofdolomitizationwith particular attention given tothoseinferred in the Dundee Formation.Hydrothermal dolomite in structurally-controlled fractured reservoirs and sucrosic dolomite in evaporativesettings will be discussed in detailwith a focus on thereservoir geometries andproperties associated with these different dolomite types. Steve earned his PhDfrom Michigan State University in 2005. His research aims at a better understanding of dolomite nucleation and crystal growth.He has six years of previous industry experience withExxonMobil Upstream Research Company (2005-2011). He returned to academia in2011.

1:50-2:20 Break and core examination

2:20-3:00—Douglas J. Elenbaas, PE, Reservoir Engineering Consultant, ElEnergy Consulting, and consultant with Brock Engineering, will present “Dundee Oil, Reed City and Goodwell,” discussing his family’s experiences in the Goodwell Field, Newaygo County, from 1947 through 2017, with focus on the Reed City Unit, the last remaining producing zone. The seven zone total native production exceeds 2 MMBbls oil and 30 Bcf Natural Gas (1943-2016).The Michigan Stray was also converted to an outstanding 19.3 Bcf working gas storage field in 1948. Doug received his BS from the University of Michigan and has more than 40 years’ experience in gas storage and petroleum engineering.

3:00-3:45—C. Curtis Crumrine, PE, Vice President, W. B. Osborn Oil and Gas Operations, will discuss recently developed techniques for determine core properties, using an example from a core taken from their Fork (Dundee) Field in Mecosta County, MI. The primary goal was to determine, first-hand, the nature of the porosity and what portion of the porosity could be expected to contribute to production under normal production processes. The Lab used CT, full-diameter analysis techniques, and high-resolution SEM to obtain data. He will recap and update the results obtained using this technology in the last two years. Tim Brock, PE, Brock Engineering, LLC, will join Curt during the last portion of this presentation for an open discussion of the relevance of this core data and the Fork Field and to discuss the production and economic implications to current and future Dundee prospects. Curt has a BS in natural gas engineering from Texas A&I University and has over 30 years’ industry experience. Tim has a BS in Geological Engineering from Michigan Technological University and has more than 35 years of experience in the oil and gas industry.
