Development Update for an Emerging Shale Gas Giant Field—Horn River Basin, British Columbia, Canada

Abstract: The Horn River Basin covers an estimated 3 million acres in a remote and difficult to access area of northern British Columbia. A number of Operators have experimental projects in the area, using various drilling and completion techniques, in order to evaluate the shale reservoir, gas in place, and productivity; moving towards commercial projects. The Devonian age shales of the Horn River Basin have been compared to the Barnett Shale of the Fort Worth Basin, in terms of reservoir quality, productivity and reco… Show more

“…Highly reactive Fe 2+ /Fe 3+ ions may participate in production of water insoluble iron hydroxide, goethite, hematite or magnetite according to eqs to : It is worth mentioning that the imbibition experiments are conducted at room temperature, atmospheric pressure, and nearly neutral pH, which are different compared with the reservoir conditions. For example, Horn River reservoir gas contains about 9–14% of CO 2 , and the reaction of CO 2 with water can potentially produce carbonic acid. It must be noted that although carbonic acid production can reduce the pH, natural buffer systems such as dolomite and calcite may neutralize the pH under reservoir conditions .…”
