Leading Technology for Unconventional Oil and Gas Stimulation
Significantly reduces flow pressure difference and enhances artificial fracture permeability. At 2,175.6 psi closure pressure and the same displacement rate, HEP cuts flow pressure by over 90% and boosts permeability by 6–10 times compared to pure sand.

Equipment & Operation Procedure
Integrated Injection Skip
The modified fiber and structural stabilizer are mixed and well-dispersed through an integrated injection skid.
The mixture is then transferred to the blender truck’s mixing tank combined with the proppant and injecte to the wellbore.
