Rheological and Filtrate Control
TETRA provides a full range of rheological and filtrate control agents, including a broad range of viscosifiers and polymers. These control agents minimize formation losses, prevent comingling by separating fluids in the well, and suspend and carry solids.
These products include a broad range of viscosifiers and polymers.
An environmentally friendly liquid HEC viscosifier, its recommended treatment concentration range easily passes the U.S. Gulf of Mexico’s 96-hour acute toxicity test.
A complex, high molecular weight polymer is used as a viscosifier and suspending agent in clear brine fluids, spacers and fluid-loss control pills. A fine, granular product easily dispersed in clear brine fluids, it is highly resistant to shear degradation. BioPol viscosifier acts to elevate the yield point and shear-rate viscosity, enhancing hole cleaning and promoting gel-strength development for suspension. It provides stable rheology to temperatures of 250°+ F/120°C.
BioPol™ L Viscosifier
BioPol L viscosifiers, a liquid, high molecular-weight polysaccharide polymer in a light hydrocarbon-based oil, is used as a primary viscosifier and suspending agent for clear brine fluids, spacers, and fluid loss control pills. BioPol L is an easily mixed liquid that provides stable rheology to temperatures of 250°+ F/120°C.
BioPol™ HT Viscosifier
A dry polymer that is more compatible with divalent clear brine fluids, BioPol HT provides stable rheology for temperatures up to 300° F/148°C.
PayZone® HPS Viscosifier
A chemically modified high performance starch, PayZone HPS viscosifier reduces fluid invasion into the reservoir. Adding PayZone HPS viscosifier to a brine-based drill-in fluid or fluid-loss control pill reduces API and HP/HT filtration rates.
A dry HEC polymer, TETRAVis viscosifier is used to viscosify low-density clear brine fluids.
TETRAVis™ L Viscosifier
A concentrated, multi-purpose, liquefied hydroxyethyl cellulose (HEC) polymer, TETRAVis™ L viscosifier is used in low-density clear brine fluids.
TETRAVis™ L Plus Viscosifier
A double strength, liquefied 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/135ºC.
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.
A proprietary, high-performance, temperature-tolerant polymeric viscosifier used 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 reduces the API and HP/HT filtration rates in temperatures up to 325°F/162ºC. It mixes easily and tolerates high levels of calcium and zinc.
PseudoPol™ D Polymer
A dry, high-performance synthetic polymer used to control filtration rates in lower-density clear brine fluids.
PseudoPol™ HT Polymer
Used for high temperature fluid loss control, this polymer is dry and synthetic. It has the performance characteristics of PseudoPol polymer at temperatures exceeding 325 F/162ºC.
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 used in the formulation of cross-linked polymer pills that function as non-damaging fluid loss control/lost circulation control pills. TETRAFlex 110 polymer effectively controls fluid loss in formations with permeabilities up to two Darcy units and bottom-hole temperatures up to 250°F/120°C. It can be used with sodium, potassium and calcium completion brines with densities less than 12.0 lb/gal.
TETRAFlex™ 135 Polymer
A prehydrated gel, TETRAFlex™ 135 polymer is used in the formulation of cross-linked polymer pills that function as non-damaging fluid loss control/lost circulation control pills. TETRAFlex 135 cross-linked pills can effectively control fluid loss in formations with permeabilities up to two Darcy units and bottom-hole temperatures up to 250°F/120°C. It can be used in sodium, potassium, calcium, and zinc completion brines with densities greater than 12.0 lb/gal.
