The Trenton Limestone in Northwestern Ohio has been targeted for hydrocarbon exploration and evaluation because it offers the possibility of good economic returns with low costs, good leasehold availability, and an opportunity to test modern reservoir stimulation technology.
Results of exploration efforts have shown that (1) geological high-grading of well site selection was needed, (2) there is a need for stimulation treatments designed to enhance production, (3) there is a marginal return on investment with current economics, and (4) gas pipeline construction should be delayed until larger reserves are found or until a more favorable gas marketing climate develops.
Figures & Tables
The Trenton Group (Upper Ordovician Series) of Eastern North America: Deposition, Diagenesis, and Petroleum
Regional facies for the Upper Ordovician Series (global classification) of eastern North America consist of clean (pure) carbonates, mixed carbonates and terrigenous clastics, shale, terrigenous clastics coarser than shale, and terrigenous clastics prograding over carbonates. The last facies is characteristic of the Upper Ordovician. Maps and cross sections for stages of the Upper Ordovician demonstrate the influence of regional tectonic events on the sedimentation pattern of these facies.
