In this era brimming with opportunities and innovation, Dongying Linguang New Material Technology Co., Ltd. has distinguished itself as a leader in the field of Sodium Carboxymethyl Cellulose (CMC) and Poly Anionic Cellulose (PAC) with its exemplary strength and pioneering spirit. Situated in Dongying City, Shandong Province—the heart of the Yellow River Delta, the petroleum city, the company has a registered capital of 48 million yuan and spans over 200 acres. It has a workforce of 230 employees and fixed assets worth 230 million yuan. This technology-oriented enterprise integrates research and development, production, sales, and services. Its core business operations include the production and sales of Sodium Carboxymethyl Cellulose, import and export trade, modern logistics, international trade, sulfuric acid, among others. The annual production capacity of its primary products reaches up to 20,000 tons. As a council member of the China Cellulose Industry Association, the company has successively garnered numerous accolades, such as the “Provincial Quality Benefit Private Enterprise,” “Provincial Contract-abiding and Trustworthy Enterprise,” and “Shandong Province Consumer Satisfaction Unit.”

PAC & CMC can be used in drilling fluid, fixing fluid and fracturing fluid. In drilling fluid, it works as viscosifier, filtration reducer, and rheology controller; in fixing fluid, it is used to control fluid viscosity, suspend heavy objects, and avoid fluid loss; in fracturing fluid, it is used to carry stuffing and avoid fluid loss. And PAC also used as a thickener for low-density brines, as rheology modifier.

When CMC is used in fracturing fluid, it can bring 'stuffing' into the cracks of oil well in high efficiency and establish osmosis channel, which can effectively prevent fluid entering into oil well structure, reduce fluid loss, and lower the pressure.
The ultra high viscosity products can replace guar gum, reduce the production cost.
Technical Specifications of CMC for Fracturing Fluid

Instant products, like the granular PAC, used in severe environment, it will be more convenient and simpler, and it will be more effective in mud allocating.

Applications in Fresh Water, Sea Water and Saturated Water
1. Improves filtercake lubricity.
2. Stabilizes fluid rheology.
3. Cost effective, small usage, high yield.
4. Excellent salt tolerance and anti-bacteria property, convenient to use.
5. Outstanding API filtration control and suspending ability. Improve the viscosity significantly.
6. Environment friendly

Applications in Drilling Fluid
1. Protect the wall of oil well, prevent mud flowing away and carry crumbs.
2. Protect drilling bit and increase drilling speed.
3. In low solid or none solid drilling fluid, it can reduce the fluid loss and the thickness of the mud cake obviously.
4. Strong inhibition effect to shales swelling and disintegration.
