Filtration Reducers

Reduce fluid filtration of water- or nonaqueous-based drilling fluids

M-I SWACO offers a complete line of chemicals used to reduce drilling fluid filtration and improve filtercake quality while drilling permeable formations.

Nonaqueous Polymeric Fluids

ECOTROL F

Filtration-control additive

The product is especially designed to complement the emulsifiers of oil - and synthetic -base mud systems to provide tight high-temperature, high-pressure (HTHP) fluid loss control at a low product concentration.

ECOTROL HT

High-temperature filtration-control additive

The product provides high-temperature, high-pressure (HTHP) fluid loss control in extreme high temperature environments up to 260° C (500° F).

ECOTROL RD

Filtration-control additive

This additive reduces HPHT fluid loss at temperatures up to 375 degF [191 degC].

MEGADRIVE F

Fluid loss control additive

Suitable for use in all paraffin-, mineral oil-, or synthetic-based drilling fluid systems.

NOVATEC F

Filtration-control additive

A maleated rosin polymer/glycol ether used as a fluid- loss reducer in the Novatec synthetic drilling fluid system.

ONE-TROL HT

High-temperature filtration control agent

Amine-treated tannin is a filtration-control additive designed for use in all oil and synthetic-base drilling fluid systems.

Nonaqueous Particulate Fluids

VERSATROL

Asphaltic resin

Used to seal low-pressure and depleted formations.

VERSATROL HT

High-temperature asphaltic resin

Often used to seal low-pressure and depleted formations.

VERSATROL M

Asphaltic resin

Often used to seal low-pressure and depleted formations.

Water-Based Modified Natural Polymer Fluids

POLYPAC ELV

Extralow-viscosity polyanionic cellulose additive

Primarily used in weighted systems to avoid an uncontrollable viscosity build-up.

POLYPAC UL

Ultralow-viscosity polyanionic cellulose

Controls fluid loss in freshwater, seawater, KCl and salt muds.

POLYPAC R

Polyanionic-cellulose filtration-control additive

Controls fluid loss in freshwater, seawater, KCl, and salt muds.

M-I PAC R

Technical-grade polyanionic-cellulose filtration-control additive

A fluid-loss and viscosity-control additive.

M-I PAC UL

Technical-grade ultralow-viscosity polyanionic-cellulose filtration-control additive

Low-viscosity, tech-grade fluid-loss- control polymer.

Water-Based Synthetic Material Fluids

SP-101

Water-based-mud fluid loss control additive

A medium-molecular-weight, anionic additive used to reduce fluid loss in freshwater and seawater muds

RESINEX II

Premium-grade resinated lignite

A filtration agent and rheological stabilizing additive for all water-base drilling fluids with chlorides below 70,000 mg/L and hardness not exceeding 3,000 mg/L.
