Abstract
A method of fracturing subsurface formation includes super-cooling water to a temperature between −4° F. to −30° F. using liquid nitrogen having a temperature in a range of −100° F. to −200° F., pumping the water down a wellbore to create fractures in the subsurface formation, and pumping fracturing fluid containing a proppant down the wellbore after pumping the water down the wellbore.
