The advantages of LPG gel vs. water

LPG fracturing is one of those rare technology breakthroughs in the oil and gas industry that can deliver both economic and environmental benefits for producers.

As much as 80% of the water that's used in conventional methods stays in the reservoir and most of the water that does flow back has to be disposed of safely.

Using LPG allows operators to use hydrocarbons already being produced to extract more hydrocarbons while also eliminating the need for biocides required in conventional fracturing.

When gelled with our proprietary chemicals, LPG provides a consistent viscosity, does not require the costly use of CO2 or N2, nor does it require any special cool down or venting of equipment. LPG—an abundant by-product of the natural gas industry—is stored at ambient temperature.

Using LPG also reduces the need to flare production to clean up the traditional fracturing fluids, reducing CO2 emissions.

Because propane liquid is half the specific gravity of water, there is reduced trucking to the site and no trucking to transport post stimulation - which can reduce truck traffic by up to 90%.
