Acid Fracturing - CNPC
Acid Fracturing - CNPC

This kind of fluid for fracturing minimizes reservoir damage, thanks to its minimal residue, high backflow percentage, little leakoff, and plug removal under faint acidity. It is suitable for the treatment of oil and gas wells in low-permeability and tight formations. Thermo-chemical composite fracturing
