Production

Illinois Basin

TEI currently operates 25 leases in the Illinois Basin. These leaseholds represent over 150 active production and injection wells that collectively produce over 125 bopd.

Indiana

Operate/Operated in excess of 100 wells in the State of Indiana. These wells varied from shallow Pennsylvanian wells, to Lower Mississippian-aged carbonate reservoirs. Fields have produced under both primary and secondary recovery methods.

Kentucky

Operate/Operated in excess of 150 wells in the Commonwealth of Kentucky. These wells are primarily Middle Mississippian sandstone and carbonate reservoirs produced under primary and secondary recovery methods.

Illinois

Operate/Operated in excess of 100 wells in the State of Illinois. Wells range from late Pennsylvanian sandstones to Late Mississippian carbonate limestones. Many of the fields were under secondary recovery programs implemented by TEI.

Michigan Basin

Southern Reef Trend

Drilled and produced Niagara Reef (Silurian Reef) wells. Drilling techniques were vertical and medium radius directional drilling.

Antrim Shale

Performed an extensive geologic study and subsequent royalty acquisition in this shale gas formation, located in NE Michigan. In addition did several seismic exploration projects in the Northern Reef trend.

Trenton/Black River

TEI participated with other operators and drilled its own wells in an extensive exploration program utilizing 3D seismic adjacent to the prolific Albion-Scipio Field in South Central Michigan.  The Trenton/Black River reservoir is a fractured enhanced vugular dolomite located in structural sags and exhibit hydrothermal solution and mineralization.  The Albion-Scipio Field has produced over 124MMBO and 205 BCF while the adjacent Stoney Point Field has produced 13MMBO and 28 BCF.
