Micro-Gel

Losing the fluid phase of a slurry into the soil can compromise the integrity of the formations. This can allow materials to fall in against the segments, increasing drag and elevating jacking pressures. Micro-Gel slurries protect against excessive fluid loss by laying down a thin tough filter cake that limits the water phase influence on surrounding formations. Traditionally used slurries demonstrate fluid loss values nearly twice the level of Micro-Gel.

Used as a Slurry Fluid: Maintaining formation integrity while cutting lays the foundation that keeps jacking pressures low. Using Micro-Gel as the slurry fluid limits negative impact on soils and maintains the bore wall continuity. Mixing rate should be 320 pounds of Micro-Gel per 1000 gallons (144 kg/3.8 m³ ). Fluid characteristics will have a Marsh Funnel Viscosity of 45 to 48 sec/qt.

Used as a Lubricating Fluid: For best results, a venturi or other high-shear equipment should be used. Mix rate is 22.5 pounds per barrel or 535 pounds per 1000 gallons (241 kg/3.8 m³ ) of make-up water. This mix ratio will yield a Marsh Funnel Viscosity of 80 to 85 sec/qt.
