3M™ Glass Bubbles HGS18000

3M™ Glass Bubbles HGS18000 are hollow spheres made of soda-lime borosilicate glass with a true density of 0.60 g/cm³ and an isostatic crush strength of 18,000 psi or 1240 bar.

HGS18000 Glass Bubbles are well-suited for use in ultra-deep wells as an additive for lightweight well cementing in the oil and gas industry. HGS18000 Glass Bubbles added to lightweight cement slurries help prevent problems associated with excessive overbalance, including reduced top of cement (TOC) and thus the need for remedial squeeze.

• 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
• high strength
