Hydroxyethyl Cellulose (HEC) Oilfield Grade: Premium Viscosifier for Drilling & Fracturing

Introduction: Trusted HEC Supplier for Oilfield Excellence

Qingdao Unionchem Co.,Ltd. is a leading manufacturer of API 13B-2 certified Hydroxyethyl Cellulose (HEC), engineered for high-performance oilfield applications. With ISO 9001 and REACH certifications, our HEC delivers exceptional viscosity control, fluid loss reduction, and thermal stability (up to 150°C) in water-based drilling fluids and fracturing fluids. As the global oilfield chemicals market grows at 4.6% CAGR (2025–2035), we supply 3,000 MT annually to 25+ countries, empowering clients like Halliburton and Petrobras to achieve 20% higher drilling efficiency and 30% lower fluid costs.

Product Portfolio: Engineered for Extreme Conditions

Grade	Viscosity (2% Solution, cps)	Molar Substitution (MS)	Key Applications
HEC-HV	3000–5000	2.5–3.0	Drilling fluids, suspension of cuttings
HEC-MV	1000–3000	2.0–2.5	Completion fluids, fluid loss control
HEC-LV	500–1000	1.8–2.2	Fracturing fluids, friction reduction

Technical Advantages: Beyond Conventional Additives

1. Superior Rheological Control

• Shear-Thinning Behavior: Reduces viscosity under high shear (drill bit) for lower pump pressure, then rethickens to suspend cuttings during static conditions .

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

2. Extreme Temperature Stability

• Thermal Resistance: Stable at 150°C for 72+ hours, outperforming xanthan gum by 30% in HPHT wells .

• Low Gel Strength: Minimizes pressure spikes during tripping operations, reducing wellbore instability risk.

3. Environmental & Cost Efficiency

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

• Low Dosage: 0.3–0.5% concentration achieves optimal viscosity, reducing chemical costs by 25% vs. guar gum.

Industry-Specific Solutions

Horizontal & Deepwater Drilling

• Wellbore Stability: HEC-HV reduces fluid loss by 40% in shale formations, preventing clay swelling and well collapse (Case Study: Permian Basin, 2024).

• Cuttings Transport: MV grade improves hole cleaning efficiency by 30% in 10,000+ ft horizontal wells.

Hydraulic Fracturing

• Proppant Suspension: LV grade enhances sand-carrying capacity by 50% in slickwater fracturing, increasing fracture conductivity.

• Friction Reduction: Lowers pipeline friction by 40%, enabling higher pump rates with lower energy consumption.

Completion & Workover

• Brine Compatibility: Effective in CaCl₂ and KCl brines, maintaining viscosity in 15% calcium chloride solutions.

• Filter Cake Quality: Thin, impermeable filter cake reduces formation damage, improving well productivity.
