Yoho cheers Duvernay flows

Cheers: Yoho flows Duvernay wells

Yoho Resources flowed a pair of wells in the emerging Duvernay shale play in Alberta with results the Calgary-based junior viewed as encouraging.

The first well, located at 16-04-62-21, was drilled to a measured depth of 4740 metres with a 1300-metre horizontal section within the Duvernay, a Devonian-aged shale.

The well flowed at peak rates of 4.6 million cubic feet per day, or about 1200 barrels of oil equivalent per day including condensate and natural gas liquids, during initial clean-up.

After about 117 hours, the well was producing at a restricted rate of 2.5 MMcfd, or about 670 boepd.

The well, which was operated by Yoho, cost about $12 million to drill and complete.

A second well, operated by an unnamed third party and located at 16-02-60-19 W5, was drilled to a measured depth of 4710 metres, also with a 1300-metre lateral and an estimated cost of $12 million.

It flowed up to 3.6 MMcfd, or about 900 boepd.

Both wells were drilled as part of Yoho's Duvernay programme at Kaybob, Alberta. They are each tied into gathering systems and expected to be on stream upon the completion of surface facilities currently being constructed.

"Yoho is very pleased with the strong early flow characteristics from these wells and looks forward to the application of technologies used in the completion of these wells to longer laterals in future wells," the company said.
