Qingdao Unionchem Co.,Ltd. is a trusted supplier of API 10A certified welan gum, a microbial exopolysaccharide engineered for extreme conditions in oilfield and construction industries. With ISO 9001 and REACH certifications, our welan gum meets global standards for thermal stability (up to 180°C) and environmental safety. As the global welan gum market grows at 5.5% CAGR (2025–2034), we deliver 2,000 MT annually to 25+ countries, empowering clients like Schlumberger and Cemex with cost-effective solutions that enhance operational efficiency by 30%.
| Grade | Viscosity (1% KCl, mPa·s) | Temperature Stability | Key Applications |
|---|---|---|---|
| WG-P (Premium) | ≥1800 | 180°C (BHCT) | Oilfield cementing, HPHT wells |
| WG-S (Standard) | 1500–1700 | 150°C (BHCT) | Construction concrete, self-leveling mortars |
| WG-D (Dispersible) | 1600–1800 | 160°C (BHCT) | Fracturing fluids, offshore drilling |
Extreme Temperature Resistance
Maintains viscosity at 180°C for 72+ hours, outperforming xanthan gum by 40% in thermal stability tests .
Ideal for deepwater wells and geothermal projects with bottomhole temperatures up to 210°C.
Superior Cement Slurry Performance
Suspension: Prevents settling of weighting agents (e.g., barite) with 0.1% addition, reducing sedimentation by 90% .
Fluid Loss Control: API filter loss ≤50 ml at 6.9 MPa, ensuring wellbore integrity in permeable formations.
Eco-Friendly & Cost-Efficient
Biodegradable: 80% degradation in 28 days (OECD 301B), compliant with EU Mine Waste Directive 2006/21/EC.
Low Dosage: 0.05–0.2% concentration achieves optimal results, reducing chemical costs by 25% vs. cellulose derivatives.
HPHT Wells: WG-P grade ensures uniform cement placement in Gulf of Mexico ultra-deep wells (10,000+ ft), with thickening time adjustable from 2–4 hours.
Fracturing Fluids: WG-D grade enhances proppant transport efficiency by 35% in Permian Basin shale formations.
Self-Compacting Concrete: WG-S grade improves workability and sag resistance, allowing placement in complex formworks without vibration.
Shotcrete: Reduces rebound loss by 20% in tunnel construction, improving project productivity.
Quality Assurance: In-house API 10A testing lab ensures batch consistency (viscosity variation ≤5%).
Technical Expertise: Custom formulation support for specific downhole or construction conditions.
Global Logistics: 10-day delivery to Houston, Rotterdam, and Singapore ports, with bulk packaging (25kg bags/1MT supersacks).
Competitive Pricing: Factory-direct costs 15–20% lower than international brands (FOB Qingdao: $5.8–7.2/kg for bulk orders).
