The Ontario properties are onshore and offshore wells in Lake Erie, near Port Colborne, for which the buyer, Calgary-based Eurogas, paid $131 million.

Eurogas's primary project is its part interest in a $2-billion offshore gas storage facility in Spain, expected to be operational in 2012. Eurogas said in a news release the properties will provide it with cash flow of $2 million per month.

Talisman didn't disclose the names of the other buyers. Typically in the oil industry, it's left to the buyers to disclose the sale because there might be competitively sensitive issues at play.

Talisman will use the proceeds from its sale to develop its North American shale gas business. New technology is enabling energy companies to create fractures underground to produce gas from previously inaccessible shale formations. Talisman is exploring in shale formations in New York, Pennsylvania and Quebec.

Talisman shares closed down 43 cents at $17.40 in Toronto Wednesday.
