3M™ Glass Bubbles HGS4K28, 40 kg

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.

HGS4k28 Glass Bubbles are designed for use in drilling, completion, and workover fluids, as well as in cement slurries from shallow to intermediate depth waters in the oil and gas industry.

• 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
• Chemical stability and inertness
• Temperature resistance
• smaller particle size
