3M™ Glass Bubbles K1 are engineered hollow glass microspheres made of water-resistant and chemically resistant soda-lime borosilicate glass with a true density of 0.125 g/cm³ and an isostatic crush strength of 250 psi / 17 bar.
HGS8000X Glass Bubbles are well-suited for use in moderate to deep wells, designed for use in drilling, completion, and workover fluids, as well as cement slurries for the oil and gas industry. The use of 3M Glass Bubbles HGS series as density reducing agents in the well offer the potential for reduced Non Productive Time (NPT), improved well integrity, and increased well productivity. When drilling and cementing across highly depleted zones and weaker formations, low density systems are required to prevent or minimize fluid loss/lost circulation, formation damage and other problems associated with excessive overbalance conditions. HGS Glass Bubbles offer stability by maintaining target pressures with greater reliability throughout the drilling process. HGS8000X are well-suited for use in moderate to deeep wells.
