3M™ Glass Bubbles HGS19K46

3M™ Glass Bubbles HGS19K46 are high-strength, low-density additives specially formulated to afford greater survivability than other lightweight additives under demanding downhole conditions. They are hollow glass microspheres made from water-resistant and chemically-stable soda-lime borosilicate glass.

When drilling and cementing across highly depleted zones and weaker formations, low-density systems are required to prevent/minimize problems associated with excessive overbalance conditions. These problems include fluid loss/lost circulation, differential sticking, minimal penetration rates, formation damage, and reduced well productivity. The use of 3M™ Glass Bubbles HGS19K46 as density reducing agents for drilling, completion, work-over fluids, and cement slurries offers the potential for reduced non-productive time (NPT), improved well integrity, and increased well productivity.
