Introduction

SHARKPAC®R 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®R can provide secondary viscosity and effective at low concentrations. It is non-toxic and does not require a biocide. SHARKPAC®R will create an envelope around exposed shales and cuttings to encapsulate them, reducing dispersion and permitting improvement of wellbore integrity. The encapsulation protects the shale from exposure to water.

Applications/Functions

• Control filtration rates and provide supplementary viscosity
• Aids in the formation of a thin, resilient, low-permeability filter cake to minimize the potential for differential sticking and the invasion of filtrate and mud solids into permeable formations.

Advantages

• Temperatures stable up to 300°F
• No fermenting, no biocide needed
• Effective in fresh water, seawater and brine fluids
• Functions in high pH range
• Encapsulates shale particles to inhibit swelling and dispersion
• Environmentally compatible

Typical properties

• Appearance: White, free-flowing powder
• Specific gravity: 1.5-1.8
• pH (1% aqueous solution):8

Recommended Treatment

• A typical treatment range is 0.5-2 ppb

Package
