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

Provides tight HPHT fluid loss control at a low product concentration.

ECOTROL HT

High-temperature filtration-control additive

HPHT fluid loss control in environments up to 500 degF [260 degC].

ECOTROL RD

Filtration-control 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

Imparts rapid reduction in HPHT filtration when used at relatively low concentration levels.

ONE-TROL HT

High-temperature filtration control agent

Effective alternative to asphalt and gilsonite where their use is undesirable.

Nonaqueous Particulate Fluids

VERSATROL

Asphaltic resin

Seal low-pressure and depleted formations.

VERSATROL HT

High-temperature asphaltic resin

Filtration control at ultrahigh temperatures.

VERSATROL M

Asphaltic resin

Low softening point for filtration control over large temperature range.

Water-Based Modified Natural Polymer Fluids

POLYPAC ELV

Extralow-viscosity polyanionic cellulose additive

Primarily used in weighted systems to avoid uncontrollable viscosity buildup.

POLYPAC UL

Ultralow-viscosity polyanionic cellulose

Controls fluid loss with minimal increase in viscosity in water-based muds.

POLYPAC R

Polyanionic-cellulose filtration-control additive

Controls fluid loss in freshwater, seawater, potassium chloride, and salt muds.

M-I PAC R

Technical-grade polyanionic-cellulose filtration-control additive

Controls filtration and increases rheology, especially effective in saltwater brines.

M-I PAC UL

Ultralow-viscosity polyanionic-cellulose filtration-control additive

Control filtration with minimal increase in rheology and at all pH ranges.

Water-Based Synthetic Material Fluids

SP-101

Water-based-mud fluid loss control additive

Reduce fluid loss in freshwater and seawater muds.

RESINEX II

Premium-grade resinated lignite

Filtration agent and rheology-stabilizing additive for water-based drilling fluids.
