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

| Product Stability
Drilling Specialties Liquid HEC 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. Drilling Specialties Liquid HEC was one of the first, and remains one of the most effective, of the Drilling Specialties products made with this dependable technology. Advantages
Performance Fann 35 viscosity data are shown in Tables 1 and 2 below for Drilling Specialties’ Liquid HEC polymer in a 3% ammonium chloride brine and in a saturated sodium chloride fluid. In a typical field application, Liquid HEC polymer 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 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. | |||||||||||||

Drilling Specialties’ 40% active Liquid HEC polymer 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.
