Increased well performance
A Better Way to Stimulate Wells
GASFRAC's LPG technology creates more effective frac lengths and achieves 100% recovery more quickly than traditional hydraulic fracturing techniques
RESULTS*: Higher initial production and immediate economic benefits
*Actual production results above. GASFRAC does not guarantee similar results for all wells
Why LPG?
Ultimate Reservoir Performance & Certainty
-Create the required fracture geometry
-Effective proppant transport
-Non-Damaging (Water Blocks, Polymer Residue, Clay Swelling)
-All created fracture volume contributes to production
-Only proppant remains in the frac
LPG can be Handled as a Liquid on the Surface
-Easily cross-linked to create desired frac geometry and achieve ideal proppant transport
-Achievable and “Adjustable” break times
-Industry LPG standards ensure fluid consistency
Post Job, it Disappears → ~100% Fluid Recovery
-LPG is soluble with natural gas
-1st contact miscible with crude oil
-Very low viscosity, surface tension, & density when compared to water

Impact of Reduced Viscosity:
An order of magnitude reduction in viscosity results in an order of magnitude reduction in pressure required to move the same volume of fluid through a porous media. This greatly improves post frac fluid recovery and maximizes the effective fracture length.
Impact of Reduced Surface Tension:
Surface tension of the treatment fluid is directly proportional to capillary threshold pressure or differential pressure required to mobilize fracturing fluid during cleanup. This greatly improves post frac fluid recovery and maximizes effective frac length.
