Product Description

Product Description

BLACKNEX^® resin lignite is a filtration control agent and rheological stabilizing additive for all water-based drilling fluids with chlorides below 70,000ppm and hardness not exceeding 3,000ppm. BLACKNEX^® should be used at pH greater than 10.0 to assure solubility. BLACKNEX^® will not increase viscosity, but will stabilize the fluids at increased bottom hole conditions while controlling HPHT filtration rates. BLACKNEX^® is useful to assist in controlling shale stability and hole washout.

Applications/Functions

• Effective HPHT filtration control agent in basically all water-based fluids
• Replace basic filtration polymers that lose their ability to control HPHT filtration rates at elevated bottom hole temperatures

Advantages

• Temperatures stable to >425°F
• Does not increase viscosity
• Solubilizes readily in alkaline fluids
• Enhance hole stability

Typical Properties

• Appearance: Dark brown powder
• Specific gravity: 1.35
• pH (5% aqueous solution): 8.8-9.2

Recommended Treatment

• A typical range is 2-8 ppb
• BLACKNEX^® is recommend to be pre-solubilized in a caustic solution, and added to the active system as a liquid

Package

• 25 KG SACK
