Improve displacement and control pressure and thinning
Hi-Dense® No. 4 weight agent uses non-radioactive and non-magnetic hematite material to produce four distinct benefits. Operators rely on the weight agent to help control high formation pressures, increase slurry densities, improve mud displacement, and reduce thermal-thinning effects.
Hi-Dense No. 4 weight agent has only a slight effect on thickening time and does not significantly reduce the compressive strength of set cement. The additive is also effective at preventing thermal thinning at high temperatures.
Hi-Dense agents are classified according to mesh size, and no more than 90% of Hi-Dense No. 4 agent will be smaller than 325-mesh (45 mm).
Our No. 4 hematite-ore additives can be mixed to form 26-lb/gal slurries with an effective specific gravity of 3.15. Fluidized Hi-Dense No. 4 agent requires 2.4 gal of water per 100 lbs of agent, resulting in a slurry weight of 25 lb/gal with a specific gravity of 3.0.
