Carboxymethyl Cellulose (CMC) Oilfield Grade: API 13A Certified Fluid Loss Reducer

Introduction: Trusted CMC Supplier for Oilfield Excellence

Qingdao Unionchem Co.,Ltd. is a leading manufacturer of API 13A certified Carboxymethyl Cellulose (CMC) for oil and gas drilling. With ISO 9001 and REACH certifications, our CMC-LV and CMC-HV grades deliver exceptional fluid loss control, viscosity building, and thermal stability (up to 150°C) in water-based drilling fluids. As the global CMC market grows at 3.2% CAGR (2025–2030), we supply 4,000 MT annually to 30+ countries, empowering clients like Baker Hughes and PetroChina to achieve 25% higher drilling efficiency and 30% lower fluid costs.

Product Portfolio: Engineered for Drilling Excellence

Grade	Viscosity (1% Solution, cP)	API Filtrate Loss (ml)	Temperature Stability	Key Applications
CMC-LV	≤40	≤10	120°C	Fluid loss control in high-solids muds
CMC-HV	≥50	≤23	150°C	Viscosity building in deepwater/HPHT wells

Technical Advantages: Beyond Conventional Additives

1. Superior Fluid Loss Control

• Thin Filter Cake: Forms a 2–3 μm impermeable filter cake, reducing fluid invasion by 40% in porous formations .

• Salt Tolerance: Effective in 20% NaCl brine, ideal for offshore and salt dome drilling .

2. Extreme Temperature Stability

• Thermal Resistance: Maintains performance at 150°C for 72+ hours, outperforming starch-based additives by 50% .

• Shear Stability: Pseudoplastic behavior ensures viscosity recovery after high shear at the drill bit.

3. Environmental & Cost Efficiency

• Biodegradable: 80% degradation in 28 days (OECD 301B), compliant with OSPAR and EPA regulations.

• Low Dosage: 0.2–0.5% concentration achieves optimal results, reducing chemical costs by 20% vs. PAC.

Industry-Specific Solutions

Horizontal & Deep Wells

• Wellbore Stability: CMC-HV reduces shale swelling by 35% in Montney Formation drilling (Case Study: Canada, 2024).

• Cuttings Transport: LV grade improves hole cleaning efficiency by 25% in 12,000 ft horizontal wells.

Offshore & Saltwater Drilling

• Brine Compatibility: Effective in 15% CaCl₂ brines, maintaining viscosity in saturated salt solutions.

• Filter Cake Quality: Thin,tough cake reduces reservoir losses and improves post-completion productivity.

Completion & Workover

• Fluid Loss Reduction: LV grade controls filtrate to <10 ml in completion fluids, protecting pay zones.

• Compatibility: Mixes well with other additives (bentonite, PAC, xanthan gum) without precipitation.
