3M™ Glass Bubbles HGS18000 are hollow glass spheres designed for use in lightweight well cementing for the oil and gas industry. With a nominal density of 0.60 g/cc and an isostatic crush strength of 18,000 psi (pounds per square inch), HGS18000 are well-suited for use in ultra-deep wells.
- Successfully and predictably reduces the control fluid density
- Prevents or minimizes fluid loss/lost circulation and formation damage
- Incompressible and more homogeneous control fluid properties compared with foamed and aerated systems
- Eliminates the need for specialized equipment used in foamed and aerated systems
