Liquid HEC Polymer XPT
Liquid HEC polymer XPT is a pure high-viscosity hydroxyethyl cellulosic polymer suspended in an ultra-clean mineral oil. Liquid HEC polymer XPT contains 40% by weight high-quality HEC product.

Drilling Specialties’ 40% active Liquid HEC polymer XPT will not experience the separation which is evident in other liquid products. It does not settle or experience oil separation. Starting with a fine-grade mineral oil and utilizing our unique suspension technology, we eliminate settling of the pure HEC polymer solids while the product remains fully pourable. This allows for efficient quick mixes and sweeps without the need for elaborate and expensive mixing equipment. Also, more accurate metering of active products results in improved fluid performance down hole.

Cost

Liquid HEC polymer XPT is an extremely efficient liquid suspension which eliminates loss of active polymer over shale shakers, thus reducing overall fluid costs.

Mud Types

All known water-based formulations, drill-in, completion and workover fluids

Mixing Requirements

Low-shear mixing equipment is sufficient to provide thorough dispersion and homogeneous mixtures

Handling

For specific instructions on handling, refer to the MSDS.

Packaging

5-gallon pails, 55-gallon drums and 275-gallon totes

Product Stability

Drilling Specialties Liquid HEC polymer XPT is made from the Drilling Specialties Company Suspension Technology. This technology is well known for the quality and stability of suspension products it produces. By preventing polymer settling and oil separation, the technology assures trouble-free storage, transport and mixing - all essential to cost-efficient and successful operations. 

Advantages

  • Easy to handle and mixes well in low shear rate environments
  • Works well at any salinity
  • Increases carrying capacity of fluid
  • May be poured down drillpipe
  • No "fisheyes"
  • Extremely stable suspension
  • Highly effective viscosifier
  • No preservative needed

Performance

Fann 35 viscosity data are shown in Tables 1 and 2 below for Drilling  Specialties’ Liquid HEC polymer XPT in a 3% ammonium chloride brine and in a saturated sodium chloride fluid.

In a typical field application, Liquid HEC polymer XPT is rapidly mixed through conventional rig mixing equipment. Complete hydration and viscosity development occur quickly and without the formation of fish eyes. In most cases, no shear mixing is needed to produce thorough dispersion and homogeneous mixtures–critical characteristics of both drilling and completion fluids exposed to the producing reservoir.

The economic efficiency from the use of Drilling Specialties’ Liquid HEC polymer XPT cannot be overlooked. Its stable suspension and rapid dispersion and dissolution ensure that all the polymer purchased becomes active in the system, not settled in the bottom of your drum.
