Kinder Morgan hits CO2 "gusher" at St. Johns field

Tom White, with Kinder Morgan, told the Arizona Oil & Gas Corporation Commission at their quarterly meeting that the lateral extension they drilled in their "10-5-30 State" well (AZOGCC Permit 964) flowed 9 million cubic ft of mostly carbon dioxide gas a day from fractures in granite and that Kinder Morgan would be taking a close look at the relationship of fractures to production.
The company is continuing confirmation drilling of the field before building a pipeline to take the CO2 to oil fields in eastern New Mexico and West Texas for enhanced oil recovery in old fields there.
A flow rate of 9 MMCFD is many times larger than anything encountered in the field so far. Kinder Morgan expects to drill as many as 25 wells in the field in the next year.
