AB: Recent investigation of the Cambrian and Ordovician carbonates in the Ohio River Valley Region indicates the presence of potential reservoirs for the sequestration of anthropogenic CO2. These formations are composed predominantly of massive dolomite and limestone. One zone of particular interest is the Cambrian Copper Ridge Formation "B" Zone with a potential transmissivity estimated at 3.4 ft2/day. This zone, along with other formations of interest, has been evaluated at three levels: reservoir tests have been conducted at the AEP #1 well at the Mountaineer Power Plant, New Haven, WV; the regional extent of the zone is being evaluated under a "piggyback" exploration program; and a detailed evaluation of the depositional features of the zone has been completed. The reservoir tests included static and dynamic flowmeter evaluation, drillstem tests, constant rate tests, chemical sampling, and mini-frac tests. An on-going exploration program to evaluate CO2 sequestration opportunities has been developed with the regional oil and gas industry. Work completed to date indicates that the "B" Zone is areally extensive. A cooperative "piggyback" approach leverages oil and gas development and exploration projects to advance the regional understanding of potential hydrocarbons resources and the brine aquifers. The third component brings together regional experts to develop a conceptual model of the depositional development and diagenesis of the Cambro-Ordovician carbonates. This in turn is used to develop a better understanding of the reservoir storage potential. These carbonates represent a significant strorage opportunity for the region. The work is supported by the Department of Energy, American Electric Power, BP, Schlumberger, the Ohio Coal Development Office, and the local oil and gas industry.
