Highlights
- Premium Product
- Low density-to-strength ratio
- Helps reduce the density of control fluids, including cement slurries, completion and workover fluids
- Helps to prevent or minimize fluid loss/lost circulation and formation damage
- Incompressible and more homogeneous control fluid properties compared with foamed and aerated systems
- Virtually eliminates the need for specialized equipment used in foamed and aerated systems
- Potential for reduced Non Productive Time (NPT), improved well integrity and increased well productivity
3M™ Glass Bubbles HGS8000X are hollow glass spheres designed for use in drilling, completion, and workover fluids, as well as cement slurries for the oil and gas industry. With a nominal density of 0.42 g/cc and an isostatic crush strength of 8,000 psi (pounds per square inch), HGS8000X are well-suited for use in moderate to deep wells.
What are 3M™ Glass Bubbles?
3M™ Glass Bubbles HGS Series are engineered hollow glass spheres made from water-resistant and chemically-stable soda-lime-borosilicate glass. The use of 3M glass bubbles HGS series as density reducing agents in well construction applications offer the potential for:
- Reduced Non Productive Time (NPT)
- Improved well integrity
- Increased well productivity
When drilling and cementing across highly depleted zones and weaker formations, low density systems are required to prevent or minimize fluid loss/lost circulation, formation damage and other problems associated with excessive overbalance conditions. Our 3M Glass bubbles offer stability by maintaining target pressures with greater reliability throughout the drilling process. Minimizing the differential pressure (bottom hole pressure minus reservoir pressure) is essential for the success of any drilling operation.
3M™ Glass Bubbles HGS8000X in Cementing
3M glass bubbles HGS8000X added to light weight cement slurries help prevent problems associated with excessive overbalance, including reduced top of cement (TOC) and thus the need for remedial squeeze. Additional benefits include the potential for:
- Reduced wait-on-cement (WOC)
- Reduced need for multi-staging
When compared with other microspheres, cementing with HGS8000X in moderate to deep wells offers:
- Consistency batch-to-batch and location-to-location
- Greater density reduction capacity (cement slurry density values below 9.0 lb/gal (1.1 Kg/l) have been achieved)
