PETROLIA: FAVORABLE COMPARISON OF ANTICOSTI WITH THE UTICA SHALE IN OHIO
Petrolia Inc. has revealed the results of a petrophysical study done by Schlumberger Canada Ltd. which shows that the Anticosti Macasty can be compared advantageously with the Utica shale in Ohio. The rock parameters of both formations are very similar, including with respect to thickness, total organic carbon (TOC), clay content and hydrocarbon saturation. The porosity of the Macasty shale in the Petrolia Chaloupe well averages 4 per cent to 6 percent, which compares favourably with the Ohio shales with an average of 3 per cent to 5 per cent. This factor, together with the permeability analysis carried out earlier, is a positive indicator of the potential for oil and gas production of the Macasty shale.
The study compares the petrophysical properties of the Utica shale in the Ohio geological survey CO2 No. 1 well with those of the Macasty shale (a lateral equivalent of the Utica shales) in the Petrolia/Corridor Chaloupe No. 1 well on Anticosti Island, Quebec.
Three Chesapeake horizontal wells located between 65 kilometres and 80 kilometres northeast of the OGS CO2 No. 1 have tested between 3.1 million standard cubic feet per day and 9.5 million standard cubic feet per day of gas, and between 980 barrels per day and 1,425 barrels per day of petroleum liquids (see Chesapeake press release on Sept. 28, 2011). Corridor and Petrolia control more than 1.5 million acres of prospective Macasty lands on Anticosti Island.
