Surfactants

Surfactants reduce the surface tension and/or interfacial tension between fluids, fluid and formation, and fluid and tubulars. Their use is common in all types of treating fluids. Surfactants aid in formation cleanup through their ability to prevent emulsions, lower surface and interfacial tension, and alter wettability.

Amphoteric

AmphFoam

amphoteric surfactant

Amphoteric surfactant that provides stable foams in water and acid up to 400°F (204°C). Remains in the aqueous or acid phase instead of plating out on the rock to enhance well cleanup. The recommended concentration is 1-5 gallons/1000 gallons (1-5 L/mᵌ) as a surfactant and 5-15 gallons/1000 gallons (5-15 L/mᵌ) as a foamer.

Anionic

A-Foam

Anionic surfactant that contains an amphoteric foaming agent

Anionic surfactant that contains an amphoteric foaming agent used to provide stable foams in water and acid at temperatures above 350°F (177°C). Enhances well cleanup because it does not plate out on the formation rock. Normal concentrations range from 5-10 gal/1000 gallons (5-10 L/mᵌ).

NE 70

Oil-soluble demulsifying surfactant containing an ammonium salt of a naphthalene sulfonate

Oil-soluble demulsifying surfactant containing an ammonium salt of a naphthalene sulfonate, with an ethoxylated resin in aromatic solvents. Effectively breaks oilfield emulsions in a wide variety of crude oils. Normal concentration is 0.5-5.0 gal/1000 gallons (0.5-5.0 L/mᵌ).

NE 402

Blend of aryl-sulfonates and oxyalkylated phenol resins in an aqueous alcohol solvent

Blend of aryl-sulfonates and oxyalkylated phenol resins in an aqueous alcohol solvent system that reduces surface & interfacial tension of both acid & water systems. Disperses mud particles in hydrochloric (HCl) acid treatments. Normal concentration is 1-30 gal/1000 gallons (1-30 L/mᵌ).

Cationic

NE 50

Cationic surfactant that functions as a non-emulsifier and foaming agent

Cationic surfactant that functions as a non-emulsifier and foaming agent, as well as a surface tension reducer. Possesses excellent detergent properties to clean fracture & wellbore areas. Concentrations range from 1-3 gal/1000 gallons (1-3 L/mᵌ) as a surfactant or non-emulsifier and up to 10 gal/1000 gallons (10 L/mᵌ) as a foaming agent.

Non-Ionic

NE 201

nonyl phenol resing with additional surfactants

Nonyl phenol resin with additional surfactants that functions as a non-emulsifier and surface & interfacial tension reducer. Leaves the formation "water-wet" to assist in well clean up after fracturing and acidizing treatments. Normal concentration is 1-2 gal/1000 gallons (1-2 L/mᵌ).

NE 409

blend of non-ionic surfactants

Blend of non-ionic surfactants specially designed to prevent emulsions formed during acidizing treatments. Leaves the formation "water-wet" to assist in well clean up after acidizing treatments and improve the flow of hydrocarbons. Normal concentration is 1-5 gal/1000 gallons (1-5 L/mᵌ).

Micellular

AcidSol 101

Blend of surfactants, paraffin dispersants, and solvents

Blend of surfactants, paraffin dispersants, and solvents that clean and disperse heavy hydrocarbons from downhole surfaces, enabling more concentrated acid to react on the formation. Acts as a non- emulsifier, reduces surface tension, and provides fines suspension & water-wetting properties. Normal concentration is 2-50 gal/1000 gallons (2-50 L/mᵌ).
