Gasfrac, a Canadian company has developed a process to frac using propane instead of water. No biocides or deisel fuel is added to the propane– only a gelling agent and a breaker that assists in returning the propane gel to a gas after the pumping proceedure is complete. Nearly all the “frac fluid” is recovered to be reused or sent along with the hydrocarbons produced in the well. Truck traffic is a fraction of that compared to water since the volume of material used is so much smaller. No waste water to treat or dispose in injection wells. Has been used over 1000 sites in Canada and US and is proposed for use in Tioga county New York. LPG fraccing can also yeild more oil or gas production that water as water interferes with pumping operations. No or very little flarring of initial production to clean up the well after fraccing. It is more expensive that water in the short term. An example of solutions that can be employed.
