Integrating innovative technology
A safer and more efficient process
GASFRAC has developed unique, integrated technologies—as well as the accompanying operating procedures and safety training—that together deliver safe and efficient waterless LPG stimulation.
The chemistry takes advantage of LPG's unique characteristics: chain length, purity, surface tension and viscosity. Mass flow meters are continually monitoring the process and the system can be adjusted to provide variable viscosity and break times, as required.
Storage tanks - Utilizing a boost pump and nitrogen pressurization, a series of LPG storage tanks store and feed the LPG to the specialized sand blender. A pressurized nitrogen blanket is applied to all LPG storage tanks to ensure safety.
Sand blender - This proprietary blender is a pressurized system in which proppant is preloaded, purged and pressurized with the nitrogen. A controller uses a pressurized auger system to meter the proppant into the gelled LPG, creating a gelled LPG sand laden slurry to stimulate the reservoir.
Stimulation - Specialized high pressure pumping units inject the gelled slurry into the wellbore at the required surface pressures.
