Feature And Benefits
HEC L is shear thinning, has low gel strengths and can be mixed rapidly when preparing viscosity sweeps for cleaning large diameter surface holes.
HEC L allows for efficient quick mixes and sweeps without the need for elaborate and expensive mixing equipment.
HEC L is easy to handle and mixes well in low shear
rate environments
- Works well at High salinity
- Increases carrying capacity of fluid
- May be poured down drill pipe
- No “fisheyes”
- Extremely stable suspension
- Highly effective viscosifier
- No preservative needed
Product Function
The principal use of HEC L is the attainment of viscosity in drilling, completion and work over fluids. Fluids viscosified with HEC L will exhibit high apparent viscosity, high yield point and low fragile gel strengths.
Recommended treatment
Please see below general recommendation.
As a general viscosifier for workover and completion fluids(0.25 to 0.75 gal/bbl)
As viscosifier in carrier fluid in gravel packing(0.0 to 1.0 gal/bbl)
For viscous hole sweeps in horizontal drilling(0.50 to 0.75 gal/bbl)
For carrying capacity in clean fracture fluids (0.50 to 1.00 gal/bbl)
It is highly advisable to decide dosage based on pilot testing.
Special Use
1. As a viscosifier in NaCl, KCl and CaCl₂ brine upto 250 °F
2. As a thickener for CaBr₂ upto 150 °F.

Transportation of HEC L is not restricted by any regulatory agency.
Handling Recommendations
Utilize normal precautions for employee protection when handling chemical products. Utilize appropriate respirator, gloves, goggles and apron. Refer to the Material Safety Data
Sheet (MSDS) for this product prior to use.
Standard Packing
HEC L is packaged in 5 gallon pails.
