3M™ Glass Bubbles HGS4K28, 200 kg/Bag

3M™ Glass Bubbles HGS4K28 are hollow glass spheres designed for use in drilling, completion, and workover fluids, as well as cement slurries in the oil and gas industry. With a nominal density of 0.28 g/cc and an isostatic crush strength of 4,000 psi (pounds per square inch), HGS4K28 are well-suited for use in shallow to intermediate depth wells.

• Lowest density 4,000 psi product in the 3M™ HGS Glass Bubble Series portfolio
• 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
