Product Description

NewWate™ weighting agent is a precisely ground barite used to increase the density of any low-weight system, regardless of base fluid. It is a chemically inert powder with a specific gravity of 4.1, which meets or exceeds the American Petroleum Institute (API) Drilling Fluids Specification 13A for 4.1 barite.

The high specific gravity of NewWate weighting agent provides the necessary hydrostatic pressure to balance formation pressures while reducing well costs on low mud weight applications where 4.2 barite is not required.


NewWate weighting agent is used to increase the density of drilling fluids up to approximately 13.5 lb/gal (1.6 kg/L), and to control underground kicks and lost circulation with barite plugs.

Treatment Recommendation

NewWate weighting agent is mixed directly into the system through the hopper or through bulk tank hoppers.
