LIQUID HE® 150 Polymer XPT

Drilling Specialties’ HE® 150 Polymer is a high viscosity synthetic polymer that is useful in thickening hydrochloric acid, brines or fresh water. It shares the excellent high temperature stability found in the previous DSGA Polymer, yet provides greater efficiency by producing more viscosity with each pound of polymer. HE® 150 Polymer may be purchased as a dry polymer or as a liquid packaged as a concentrated particle suspension in order to reduce dusting, speed hydration and enhance field handling. Liquid HE® 150 Polymer XPT is particularly effective as a friction reducer in fresh water, various brines and in hydrochloric acid and has been widely used for that purpose.

Product Descriptions

There are currently two suspension formulations available, both having unique properties and advantages. The Liquid HE® 150 Polymer XPT is a suspension of polymer in iso-alkane oil. This formulation provides a number of advantages, including;

Ease of handling – This suspension flows readily, even in severe winter conditions. The actual pour point of the suspension is below -30 °F. This allows the product to be easily poured out of a bung, or metered through a positive displacement pump.

Rapid polymer hydration – Test results show complete viscosity in 2% KCl within one minute at 75 °F. This performance suggests the potential use of this product in continuous mix applications, such as Slick Water Fracturing treatments. Under adverse field mixing conditions, the Liquid HE® 150 Polymer XPT has been successfully applied directly to 11.6 ppg calcium chloride brine, with very rapid viscosity development.

Superior, long term suspension stability – This formulation utilizes a base fluid system that has been successfully used for other polymer suspensions for well over a decade. Liquid HE® 150 Polymer XPT has proven to be stable, with no indication of particle settling or phase separation for more than a year under normal storage conditions.
