Hydrofluoric definition
Hydrofluoric acid was first prepared in 1771, by Carl Wilhelm Scheele. It is now mainly produced by treatment of the mineral fluorite, CaF2, with concentrated sulfuric acid at approximately 265 °C. CaF2 + H2SO4 → 2 HF + CaSO4 The acid is also a by-product of the production of phosphoric acid from … Meer weergeven Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water.

The main difference between acid fracturing and proppant fracturing is the way fracture conductivity is created. In proppant fracturing, a propping agent is used to prop open the fracture after the treatment is completed. In acid fracturing, acid is used to “etch” channels in the rock that comprise the walls of the fracture.
