Enhanced Oil Recovery (EOR) techniques are crucial for maximizing the yield from mature oilfields. Among the advanced chemical solutions employed, Sodium Carboxymethylcellulose (CMC) plays a significant role as a thickening and gelatinizing agent, particularly in methods like polymer flooding, fracturing, and profile control. As a leading manufacturer and supplier of CMC in China, we provide high-quality products designed to boost your oil production efficiency. For companies looking to buy CMC for their EOR strategies, understanding its benefits and sourcing from a reliable provider is key.

CMC's effectiveness in EOR stems from its ability to increase the viscosity of injected fluids. This increased viscosity improves the sweep efficiency of the injected fluid, allowing it to displace more oil from the reservoir rock. In oilfield fracturing operations, CMC acts as a vital component in the fracturing fluid, helping to carry proppants into the newly created fractures and preventing premature closure. Its controlled viscosity ensures that the fluid can be effectively pumped downhole and then efficiently removed after the fracturing process is complete.

Beyond fracturing, CMC is also invaluable in water shut-off and profile control applications. By selectively plugging high-permeability zones or channels, CMC helps to divert injected water or steam to previously unswept areas of the reservoir, thereby increasing the overall oil recovery factor. This targeted approach minimizes wasted resources and maximizes the economic viability of older fields. Companies can effectively purchase CMC to implement these advanced techniques and achieve substantial production increases.

The performance of CMC in EOR is influenced by its viscosity and degree of substitution (DS). High-viscosity CMC is often preferred for polymer flooding to achieve optimal mobility control, while specific grades are utilized for fracturing and other stimulation treatments. Our commitment as a manufacturer is to offer a range of CMC products tailored to these diverse EOR applications. When you inquire about CMC price, remember to consider the specific grade and its suitability for your particular recovery method.

In conclusion, Sodium Carboxymethylcellulose is a powerful tool for enhancing crude oil production. Its application in fracturing, water shut-off, profile control, and other EOR methods contributes directly to increased reservoir sweep and improved economic returns.
