Haynesville

In 2005, Encana identified the Haynesville shale as an exciting opportunity and quietly began assembling a sizeable land position. Formed roughly 150 million years ago and more than 10,000 feet beneath the earth's surface, the Haynesville shale was originally considered too costly to develop because of the low permeability of the rock. Thanks to newer extraction technology, the Haynesville shale is now widely considered one of the most promising natural gas resource plays in North America.

In 2011 we drilled approximately 87 net wells in our Haynesville resource play.
