The use of lightweight cement slurries formulated with 3M™ Glass Bubbles offer the potential for improved well integrity and increased well productivity when cementing across depleted or naturally fractured zones, helping to minimuze or eliminate lost circulation and formation damage.
3M™ Glass Bubbles HGS Series are engineered hollow glass spheres specially formulated for a high strength-to-weight ratio, allowing greater survivability under demanding downhole conditions. Lightweight cement slurries made with 3M glass bubbles HGS Series help prevent problems associated with lost circulation such as reduced Top of Cement (TOC) and thus the need for remedial squeeze.
Unlike nitrogen-foamed cement, cement made with 3M Glass Bubbles HGS Series is more homogeneous, non-compressible and eliminates the need for specialized equipment and personnel.
Unlike cenospheres, 3M Glass Bubbles HGS Series provide consistency batch-to-batch, location-to-location; greater density reduction capabilities and better performance.
