PRODUCT INFORMATION

ActiVis Viscosifier
Environmentally friendly, ActiVis™ viscosifier is a liquid HEC viscosifier. The recommended treatment concentration range of ActiVis viscosifier easily passes the U.S. Gulf of Mexico’s 96-hour acute toxicity test.

BioPol Viscosifier
A complex, high molecular weight polymer, BioPol™ viscosifier is used as a viscosifier and suspending agent in clear brine fluids, spacers and fluid loss control pills. It is highly resistant to shear degradation and acts to elevate the yield point and shear rate viscosity, enhancing hole cleaning and promoting gel strength development for suspension. BioPol viscosifier provides stable rheology to temperatures in excess of 250ºF. It is a fine, granular product that is easily dispersed in clear brine fluids.

Note: BioPol viscosifier can be used at higher temperatures with certain clear brine fluid systems.


BioPol L Viscosifier
A liquid, high molecular weight polysaccharide polymer in a light hydrocarbon based oil, BioPol™ L viscosifier is used as a primary viscosifier and suspending agent for clear brine fluids, spacers, and fluid loss control pills. It is highly resistant to shear degradation and acts to elevate the yield point and shear rate viscosity, enhancing hole cleaning and promoting gel strength development for suspension. BioPol L viscosifier provides stable rheology to temperatures in excess of 250ºF. It is an easily mixed liquid product.

 


BioPol HT Viscosifier
A dry polymer that is more compatible with divalent clear brine fluids, BioPol™ HT viscosifier provides stable rheology at temperatures up to 300ºF.

PayZone HPS
A chemically modified high performance starch, PayZone® HPS is used to reduce fluid invasion into the reservoir. The addition of PayZone HPS to a brine based drill-in fluid or fluid loss control pill reduces API and HPHT filtration rates.

PseudoPol Polymer
A proprietary, high performance, temperature tolerant polymeric viscosifier, PseudoPol™ polymer is designed for use during drilling operations and in high temperature fluid loss control applications. It is extremely stable at high temperatures and provides excellent drill cutting integrity. PseudoPol polymer reduces the API and HPHT filtration rates of brine based drill-in fluids and fluid loss control pills at temperatures up to 325ºF. It mixes easily into the active system and tolerates high levels of calcium and zinc.

PseudoPol D Polymer
A dry, high performance synthetic polymer, PseudoPol™ D
polymer is used to control filtration rates in lower density clear brine fluids.

PseudoPol HT Polymer
A dry, synthetic polymer, PseudoPol™ HT polymer has all of the performance characteristics of PsuedoPol polymer at temperatures exceeding 325ºF. PseudoPol HT polymer is used for high temperature fluid loss control.

PseudoPol HT Liquid Polymer
A high performance, synthetic liquid polymer, PseudoPol™ HT liquid polymer is used as a viscosifier and to control filtration rates in higher density brines.

TETRAFlex 110 Polymer
A prehydrated gel, TETRAFlex 110 polymer is used in the formulation of crosslinked polymer pills that function as nondamaging fluid loss control/lost circulation control pills. TETRAFlex 110 can be used in conjunction with sodium, potassium and calcium completion brines with densities less than 12.0 lb/gal. TETRAFlex 110 crosslinked pills can effectively control fluid loss on formations with permeabilities up to two darcies and bottomhole temperatures up to 250°F.

 


TETRAFlex 135 Polymer
A prehydrated gel, TETRAFlex™ 135 polymer is used in the formulation of crosslinked polymer pills that function as nondamaging fluid loss control/lost circulation control pills. It can be used in sodium, potassium, calcium, and zinc completion brines with densities greater than 12.0 lb/gal. TETRAFlex 135 crosslinked pills can effectively control fluid loss in formations with permeabilities up to two darcies and bottomhole temperatures up to 250°F.

 


TETRAVis Viscosifier
A dry HEC polymer, TETRAVis™ viscosifier is used to viscosify low density clear brine fluids.

TETRAVis L Viscosifier
A concentrated, multi-purpose, liquefied HEC polymer, TETRAVis™ L viscosifier is used in low density clear brine fluids.

TETRAVis L Plus Viscosifier
A double strength, liquefied hydroxyethylcellulose (HEC) polymer TETRAVis™ L Plus viscosifier is suited for use in most completion and workover fluids. It provides a wide range of viscosities for fluid loss control, hole cleaning, spacer formulation, and gravel pack applications. TETRAVis L Plus Viscosifier also functions as a friction reducing agent. The liquid formulation provides superior dispersability characteristics and general ease of handling. It is degradable by time, oxidizing agents, enzymes, and temperatures greater than 275ºF.

 


TETRAVis Extender
An amine-glycol thermal extender, TETRAVis™ Extender
is typically recommended for use with TETRAVis products.

TETRA Temperature Stabilizer
An antioxidant temperature stabilizer, TETRA Temperature Stabilizer is used in the formulation of fluid loss control pills.
