The 3M™ Glass Bubbles HGS7K32 is used for down hole applications for cementing and drilling fluids.
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. These glass bubbles present a nominal density of 0.32 g/cc and an isostatic crush strength of 7,000 psi (pounds per square inch), HGS7K32 glass bubbles are well-suited for use in shallow to intermediate depth wells.
