Introduction

SHARKPAC®L filtration control additive is high-quality Polyanionic Cellulose Polymers. It is used in most water-based drilling fluids including fresh water, seawater and brine up to 300°F. SHARKPAC®L has a minimal increase in rheology, is non-toxic and does not require a biocide. SHARKPAC®L is can also encapsulate solids to control dispersion of active shale.

Applications/Functions

• Control filtration rates with minimal increase in rheology
• Aids in the formation of a tough, thin filter cake to minimize the potential for differential sticking

Advantages

• Temperatures stable up to 300°F
• No fermenting, no biocide needed
• Effective in fresh water, seawater and brine fluids
• Functions in all pH range
• Produces thin, slick, tough filter cake
• Inhibit hydratable, swelling shales

Typical properties

• Appearance: Cream-colored, free-flowing powder
• Specific gravity: 1.5-1.8
• pH (1% aqueous solution): 7.75

Recommended Treatment

• A typical treatment range is 0.5-3 ppb
