3M™ Glass Bubbles HGS4000, 317 kg

3M™ Glass Bubbles HGS4000 have a density of 0.38 g/cc and an isostatic crush strength of 4,000 psi. The HGS series glass bubbles are designed for low-density drilling fluids and cements used in the oil and gas industry.

HGS4000 Glass Bubbles are designed for use in drilling, completion, and workover fluids, as well as in cement slurries in the oil and gas industry. HGS4000 are well-suited for use in shallow to intermediate depth wells.

• Reduce rig time required compared to multiple stage cementing
• Reduce the possibility of formation break-down
• Reduce the possibility of lost circulation
• Increase efficiency of mud removal by allowing pipe rotation or reciprocation
• Increase yield per sack of cement
• Eliminate need for remedial squeeze
• Thermal conductivity reduction for better thermal insulation
