 A 1.5 m (5 foot) interval of the Gorgas well was isolated<br/>with packers as shown. Multiple 1.27 cm (0.5 inch) diameter<br/>perforation channels extend through the well casing and<br/>cement and into the Boyles sandstone formation for a distance of<br/>approximately one foot. Ureolytically active biofilm was developed in<br/>the formation pore space by injecting microbial inoculum followed by<br/>growth media as shown above. After a biofilm has been established,<br/>calcium precipitation solution was injected resulting in the precipitation<br/>of calcium carbonate minerals, which plugs the free pore space and form the biomineralization seal as shown.
