Our “Superior flexProp 40/70” frac sand has consistently achieved the highest Long-Term Conductivity and Permeability performance results ever recorded at two leading independent testing facilities. Tested up to and exceeding 10,000 psi and at 250 degrees, these performance results could eliminate the need for purchasing some resin coated products currently being used in our industry. This alone can save your company as much as 60% on your cost of proppant for each job! With these unrivaled results, this data suggests our flexProp 40/70 – when resin coated – could substitute for certain ceramic proppants!
