Utica Shale – Eastern Ohio The Ordovician-aged Utica Shale is distributed across several US states as well as Quebec, Canada and is found approximately 2,000+ ft below the Marcellus Shale. The shale is generally shallower to the West and deepens to the East. As more information becomes available, the size and extent of the Utica Shale resource will become more evident. In addition to the Utica Shale, other formations such as the Devonian shale, Marcellus shale, Clinton sandstone, Medina Sandstone, Trenton Limestone, Black River, Beekmantown dolomite and Rose Run all are potential targets below the Second Berea. With the recent technological advances in drilling techniques, numerous operators have started looking at the Utica as the next oil frontier with several operators comparing its potential to the Eagle Ford Shale in Texas and the Bakken Shale in Williston Basin of North Dakota and Montana. While it is still very early in the play operators like Chesapeake Energy, Antero, Magnum Hunter, Gulfport Energy, EV Partners, Anadarko, Petroleum Development Corp and Devon (to name a few) have been acquiring acreage in Ohio. Recent results – Utica Shale wells In October 2012, the USGS estimated the Utica shale to have 38 Tcf of recoverable natural gas, 940 MMbbl of oil and 208 MMbbls of associated liquids.

Utica Shale – Eastern Ohio The Ordovician-aged Utica Shale  is distributed across several  US  states  as  well  as  Quebec,  Canada  and  is found  approximately  2,000+  ft  below  the  Marcellus Shale.  The  shale  is  generally  shallower  to  the  West and  deepens  to  the  East.  As  more  information becomes  available,  the  size  and  extent  of  the  Utica Shale resource will become more evident.  In addition to  the  Utica  Shale,  other  formations  such  as  the Devonian  shale,  Marcellus  shale,  Clinton  sandstone, Medina  Sandstone,  Trenton  Limestone,  Black  River, Beekmantown  dolomite  and  Rose  Run  all  are potential targets below the Second Berea. 

With  the  recent  technological  advances  in  drilling techniques, numerous operators have started looking at  the  Utica  as  the  next  oil  frontier  with  several operators  comparing  its  potential  to  the  Eagle  Ford Shale  in  Texas  and  the  Bakken  Shale  in  Williston Basin of  North  Dakota  and Montana. While  it  is  still very  early  in  the  play  operators  like  Chesapeake Energy, Antero, Magnum Hunter, Gulfport Energy,  EV Partners,    Anadarko,  Petroleum  Development  Corp and  Devon (to  name  a  few)  have  been  acquiring acreage in Ohio. 

Recent results – Utica Shale wells

In October 2012, the USGS estimated the Utica shale to have 38 Tcf of recoverable natural gas, 940 MMbbl of oil and 208 MMbbls of associated liquids.

Characteristics of the Utica Shale The Utica Shale extends approximately 

170,000 square miles throughout the Appalachia Basin in the United States and Canada

Ordovician-aged organic rich black shale with inter bedded limestone with target intervals ~150 feet thick at depths between 7,500 feet and 9,500 feet

Similar to the Eagle Ford Shale with three distinct windows: oil, wet gas/condensate, and dry gas with the majority of the activity focused on the wet gas and condensate window

The “Sweet Spot” for liquids-rich gas occurs in eastern Ohio  along  a  narrow  band  which  generally  follows geologic structure

Optimum thermal history

Depth,  pressure  and  hydrocarbon composition result in excellent recoveries

  Total  Organic  Carbon  (“TOC”)  is  a measure of  organic  content  and  is  indicative  of  the quantity of kerogen in the rock, which is the source material for oil and gas

TOC is derived from core analysis; however, it can  also  be  inferred  from  open  hole  log resistivity  measurements  where  sufficient data exists for a good correlation

There is a general correlation between higher gross interval thickness and larger TOC values

East of the Ohio River, the Utica/Point  Pleasant  is  sufficiently  deep  for the  formations  to  produce  dry  gas;  these areas of high TOC also correspond to high Ro values
