Gas geysers in Hutchinson, Kan., puzzle investigators

Feb. 21?Investigators are using a combination of water-well rigs and coiled-tubing units to find and vent shallow migrating pockets of natural gas that recently sparked explosions killing two people in Hutchinson, Kan.
The exact source of the gas has not been determined. But the ?working assumption? is that the mishap is connected to the loss of an estimated 73 MMcf of gas from one of six salt caverns at the Yaggy storage facility, located 7 miles down-dip from the central Kansas community of 40,000 people.
Officials said a ?fingerprint? of the escaping gas, taken by the Kansas Department of Health and Environment (KDHE), apparently matched the gas stored at Yaggy. That facility is operated by Kansas Gas Service Co., a division of Oneok Inc., Tulsa. Kansas Gas Service provides gas to 660,000 customers in Kansas and northeast Oklahoma.
