COLUMBUS - Findings from a test well drilled in 2007 have been released by the Ohio Department of Natural Resources Division of Geological Survey.
The report greatly expands the knowledge of the state's subsurface geology and provides data that will aid in statewide efforts to reduce greenhouse gas emissions, according to an ODNR news release.
During summer 2007, the Ohio Geological Survey CO2 No. 1 test well was drilled in Tuscarawas County to a depth of nearly 8,700 feet. The well reached crystalline rocks that date more than 600 million years to a geologic time known as the Precambrian Period. The objective was to evaluate the geology in the area and its capacity for storing, carbon dioxide beneath the surface.
The CO2 No. 1 well resulted in two key findings. First, the subsurface geology found within this well is representative of the eastern Ohio region and has the potential for significant carbon dioxide storage into various geologic formations, or reservoirs, the news release stated.
Second, above the potential reservoirs are thick, impermeable rock units known asconfining units that serve to seal the CO2 within the reservoirs. Results from this well also provide significant information on several prospective oil and gas-producing horizons.
Results are available as a free download from the Division of Geological Survey website at www.ohiogeology.com.
The report, appendices and digital versions of logs also are available on DVD for $50 (plus sales tax, shipping and handling). To order, call (614) 265-6576 or email at geo.survey@dnr.state.oh.us.
