Acid Fracturing - CNPC
Acid Fracturing - CNPC

Liquid carbon dioxide and water-based ,fracturing, fluids are mixed together and pumped into wells for ,fracturing, and stimulation. 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.

In hydraulic ,fracturing, operations, these agents are commonly used as an additive in ,fracturing fluid, to facilitate its ,backflow, by reducing Pc and subsequently enhancing gas production. The results of this work recommend that using such agents enhances the gas production rate for ultratight formations but not for tight formations (it reduces the gas production rate).

was ,fluid, inflow at zones 1 and 2, but not at zone 3. Proppant ,backflow, was identified exactly where the operator had conducted hydraulic ,fracturing,, which is a clear indication that the fracture was not working as per the design intent. Hence the hydraulic ,fracturing, needed complete reassessment and re-design.
