Glass Bubbles
Glass Bubbles
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.
  • 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
