HGS2000 glass bubbles have a density of 0.32 g/cc and an isostatic crush strength of 2000 psi. The HGS Series glass bubbles are designed for low-density drilling fluids and cements used in the oil and gas industry.
Application Guide
Listed below are key applications for HGS2000 glass bubbles. Documents specific to the application are listed to the right.
Density Reducing Agents for Drilling Cements
Low-density cement slurries made with 3M Glass Bubbles HGS2000 have the potential to improve performance compared to alternative solutions like aeration or water dilution. HGS2000 glass bubbles can reduce slurry density. In addition, 3M glass bubbles provide:
High compressive strength
Minimal wait on cement (WOC)
Increased yield per sack of cement
Because HGS2000 glass bubbles are incompressible, multiple staging - commonly used in wells which require a long column of cement - can be avoided in many instances.
Density Reducing Agents for Drilling Fluids
With the addition of HGS2000 glass bubbles, you can achieve low density drilling fluids as low as 5.5 pounds per gallon (0.66 kg/l). Rated to 2000 psi, they also have the strength to survive rigorous downhole conditions. This strength makes them incompressible, ensuring constant liquid density throughout the borehole and allowing for measurement while drilling (MWD) transmission.
Like all 3M glass bubbles, HGS2000 glass bubbles are virtually insoluble in water or oil, process easily on-site and are compatible with surface cleaning and other downhole equipment.
