Hollow Glass Microspheres HN46

Hollow Glass Microspheres for Low Density Cement Slurry

Because low density cement slurries made with Glass Microspheres are incompressible - providing consistent and predictable density from the top of the borehole to the bottom - it is often possible to reduce the number of stages that it takes to pour the slurry and sometimes to eliminate staging altogether.

Glass Microspheres in low density drilling cements can decrease density to as low as 6.0 lbs/gal (0,72 kg/l) with acceptable physical properties. Other benefits are:

1.Low shrinkage

2.Less wait on cement (WOC)

3.Easy mixing

4,Higher yield

5.Good strength at 12 and 24 hours

Low-density slurry made with hollow glass microspheres/glass bubbles are ideal for use in near balance, balanced or underbalanced drilling applications in:

1.Depleted reservoirs

2.Geologically-fractured formations

3.Poorly-consolidated formations

4.High-permeability formations

5.Re-entry wells

6.Deviated wells/horizontal wells
