3M™ Glass Bubbles HGS5000

3M™ Glass Bubbles HGS5000 are hollow microspheres made of soda-lime borosilicate glass with a true density of 0.38 g/cm³ and an isostatic crush strength of 5,500 psi or 385 bar.

They are designed for use in completion and workover fluids, as well as in cement slurries for the oil and gas industry. HGS5000 Glass Bubbles are well-suited for use in intermediate depth 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
• Thermal conductivity reduction
• Temperature resistance
• Chemical stability and inertness
