BARANEX Highly sulfonated lignite polymer

Product Introduction:

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

Description

Technical Parameters

Highly sulfonated lignite polymer is designed to improve the filtration and reduce the viscosity & gel strengths of high salt (NaCl) and CaCL2 fluids under high temperature drilling conditions up to 400°F. The product is tolerant of high concentrations of sodium and KCL, as well as CaCL2 and magnesium salts. Baranex being highly sulfonated, is soluble in high brines where other products such as lignosulfonates and lignites are not effective.

Applications/Functions

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

Advantages

Stable at temperatures above 425°F
Does not increase viscosity
Solubilizes readily in alkaline fluids
Enhances hole stability
