GASFRAC of Calgary, Alberta, Canada, has developed an innovative closed stimulation process and injection method, utilizing gelled LPG rather than water based conventional formation fracturing fluids.
The firm has developed a Liquefied Petroleum Gas (LPG) or propane based gel that is as natural to a well as soil is to the earth. It’s dissolves into the formation hydrocarbons improving performance without using water.
LPG will burn of course so GASFRAC has developed a zero-oxygen, closed system and specialized equipment that protects worker safety, eliminates post-job cleanup and requires only minimal flaring that can be reduced to zero when installing the appropriate recapture facilities.
Without forcing water into the oil or gas laden rock opens the ability to quickly recover 100% of the fracturing fluid resulting in enhanced oil and gas recovery and longer sustained production. The LPG could be recaptured, reused or resold, a highly cost-effective benefit, especially for multi-stage horizontal wells.
