Hollow Glass Microspheres for Low Density Cement Slurries

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

Easy to UseGlass bubbles are engineered materials with outstanding batch-to-batch consistency. This allows for easier formulation and more accurate and predictable densities at depth. They can be used with conventional mixing and pumping equipment, and require no additional personnel or specialized training, beyond what is normally required for unmodified slurries.

Hollow Glass Microspheres for Low Density Drilling Fluids

1.Simple hydraulic calculations

2.Smooth measurement while drilling (MWD) transmission

3.No need for expensive compressors

4.Less likelihood of corrosion to the drill string

5.Reduced explosion potential
