A stabilized pourable suspension of high grade liquid hydroxyethyl cellulose polymer carefully chosen to yield the highest solution viscosities and fluid loss control under a wide range of temperatures and salt conditions. VD-HAL suspension technology is designed to eliminate product settling and fluid separation while providing excellent fluid loss and rheology modification. VD-HAL is also as a viscous hole sweeping agent in horizontal drilling and provides shale stabilization in a wide range of temperatures at any salinity. VC-HAL is composed of an environmentally friendly fluid and >35% active variety of high-grade HEC polymer suspension which, while remaining fully pourable, does not experience the settling or fluid separation evident in other liquid products. VD-HAL therefore allows for hassle-free storage, transport and mixing – leading to a lower overall operational cost and higher operational efficiency.
