WILLIAMSVILLE, N.Y. (AP) ¿ Seneca Resources Corp., a natural-gas exploration company, said Tuesday a Marcellus Shale well operated by a joint venture partner was flow tested at an average rate of over 3 million cubic feet per day for seven days.

The well is operated by EOG Resources Inc., and Seneca holds a 50 percent working interest and a 60 percent net revenue interest in the well. Seneca is a subsidiary of National Fuel Gas Co.

"This is a tremendous opportunity for Seneca, and as the primary focus of our (exploration and production) activities, we expect the Marcellus Shale to provide significant growth in production and reserves for many years," said Matthew Cabell, president of Seneca.

Shares of National Fuel rose 64 cents to $31.95 in afternoon trading.
