3M™ Glass Bubbles for Drilling Fluids

In drilling fluids, 3M™ Glass Bubbles HGS Series help attain fluid densities as low as 5.5 pounds per gallon (0.66 kg/l). 3M glass bubbles-based fluids control density efficiently, process easily at rig site and are compatible with surface cleaning and other downhole equipment. These fluids also are ideal for the range of temperatures, pressures and hostile environments found downhole.

Drilling fluids or muds made with 3M glass bubbles HGS series can provide an economic alternative to aerated drilling fluids. These reduced-density fluids are homogenous, incompressible, stable and allow measurement while drilling (MWD). They provide good borehole stability and excellent hole cleaning. These low-density fluids permit at balance, near balance or underbalanced drilling. In general, reduction of differential pressure can result in:

• Higher productivity through increased rate of penetration (ROP)
• Elimination of differential sticking
• Reduction or elimination of lost circulation
• Reduction in formation damage

3M glass bubbles are non-volatile, stable additives that provide drilling muds with durable low-density properties, both during and after a drilling job. Additionally, muds formulated with 3M glass bubbles can potentially be re-used on multiple neighboring wells where low-density drilling is required.

3M glass bubbles HGS series comes in range of strengths and densities for different downhole conditions.
