3M™ Glass Bubbles for Low Density Drilling Cements
Because low density cement slurries made with 3M™ Glass Bubbles 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.
3M Glass Bubbles 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:
- Low shrinkage
- Less wait on cement (WOC)
- Easy mixing
- Higher yield
- Good strength at 12 and 24 hours
Choose the grade of 3M™ Glass Bubbles that is right for your application:
* Target 90% survival, 80% Minimum
