Density reducing additives for control fluids and cement slurries help reduce and control downhole pressure.
When drilling or cementing across highly depleted zones and weaker formations, problems such as fluid loss, lost circulation and formation damage can threaten well productivity. Low-density systems can help you mitigate these problems by giving you more control downhole.
3M™ Glass Bubbles HGS Series are hollow glass microspheres engineered for greater survivability under demanding downhole conditions. They are used to predictably reduce and maintain the density of drilling fluids and cement slurries that help reduce and control bottom hole pressure. The use of 3M glass bubbles can eliminate the need for specialized equipment used in foamed or aerated systems. Specially formulated for a high strength-to-weight ratio, 3M glass bubbles HGS series are available in a range of strengths and densities and offer excellent consistency from batch to batch.
Low-density cements formulated with 3M glass bubbles HGS series offer the potential to reduce costs and improve performance compared to other commonly used techniques, including water-extended slurries, foamed cements or other microspheres, or more costly multi-staging.
3M glass bubbles HGS series help achieve and maintain target densities in drilling, completion and workover fluids. These low-density drilling fluids help minimize differential sticking, lost circulation, reduced penetration rates and other problems associated with excessive overbalance conditions. Glass bubble-based fluids can be reconditioned and reused, helping you reduce costs.
