In the oil and gas drilling industry, drilling fluid selection is critical. As a key additive, high-viscosity CMC (carboxymethylcellulose) drilling fluid has become an important tool to improve drilling efficiency and protect well walls due to its excellent performance.
The full name of CMC is sodium carboxymethylcellulose. As an important chemical, it is widely used in the food industry, pharmaceutical industry, cosmetic industry, and oil and gas drilling industry.
PAC-LV can effectively improve the quality of mud cake and significantly reduce water loss. It can be formulated into completion fluids of various densities under the aggravation of calcium hydride, which can make the completion fluid have lower fluid loss.
