EnCana discovered the Horn River natural gas play in 2003 and has since added extensive acreage to become the largest landholder in the basin. In 2007, EnCana formed an equal stake joint venture on a portion of the play with Apache Corporation.

In the emerging Haynesville Shale, EnCana Oil & Gas USA acquired its first leases in 2005, drilled its first three vertical wells in 2006, and has been continually acquiring land. In 2007, EnCana Oil & Gas signed an equal stake joint exploration agreement with Shell Exploration & Production, a division of Royal Dutch Shell.

Randy Eresman, EnCana’s president and CEO, said: Recent exploration wells drilled by EnCana, its partners and industry, indicate these two resource plays hold the potential to eventually become amongst the largest in North America. Each of these plays has been compared in size and scope to the prolific Barnett Shale in north central Texas, which currently produces more than three billion cubic feet per day and continues to grow.
