WaterCurb™ HMW-1
WaterCurb™ HMW-1 is a water shut off additive and crosslinkable copolymer based on high molecular weight polymer. It is a flowing gel for in-depth blocking of high permeability zones to seal fractures, fissures, and high permeability streaks.
It can be crosslinked with inorganic and organic crosslinkers to form stable gels with the strength and kinetic properties to control water conformance. Crosslinking agents used in chemical water shutoff treatments have a direct effect on the characteristics of the resulting gel, such as the gelling time, gel strength, the end application, and the stability at varying temperatures and salinities.
Crosslink density of WaterCurb™ HMW-1 depend on reservoir conditions and density of gel depend on brine/mix water used. The viscosity is stable at high temperatures, e.g. 500 Pa.s at 80 °C. Set-up Time or Gelation time of this product is typically 60-65 minutes at 80 °C.
| Properties | Typical Value |
