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.
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 |
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 .
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.
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.
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.
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.
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.
API Compliance: Full compliance with API 13A, with batch testing reports available for every shipment.
Customization: R&D team develops tailored viscosity grades within 7 days (e.g., ultra-low viscosity for slimhole drilling).
Global Logistics: 7-day delivery to Houston, Singapore, and Dubai ports, with 25kg waterproof bags or 1MT supersacks.
Technical Support: On-site fluid optimization by petroleum engineers with 20+ years of field experience.
