Product Sheet POLYPAC ELV Extralow-Viscosity Polyanionic Cellulose Additive
Controls fluid loss while providing supplemental shale inhibition.
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.
Provides tight HPHT fluid loss control at a low product concentration.
HPHT fluid loss control in environments up to 500 degF [260 degC].
Reduces HPHT fluid loss at temperatures up to 375 degF [191 degC].
Suitable for use in all paraffin-, mineral oil-, or synthetic-based drilling fluid systems.
Imparts rapid reduction in HPHT filtration when used at relatively low concentration levels.
Effective alternative to asphalt and gilsonite where their use is undesirable.
Seal low-pressure and depleted formations.
Filtration control at ultrahigh temperatures.
Low softening point for filtration control over large temperature range.
Reduces HPHT fluid loss in all oil-based systems.
Primarily used in weighted systems to avoid uncontrollable viscosity buildup.
Controls fluid loss with minimal increase in viscosity in water-based muds.
Controls fluid loss in freshwater, seawater, potassium chloride, and salt muds.
Controls filtration and increases rheology, especially effective in saltwater brines.
Control filtration with minimal increase in rheology and at all pH ranges.
