Surfactants

Why use surfactants? Well, how do you ensure full low-interfacial tension penetration of the formation? With foaming surfactants these penetrate the rock better than acid alone – speeds up the operation and efficiency!

Aquative-435®

Stimulation foamer

Description

Aquative-435 foamer is an amphoteric surfactant that provides excellent foam quality at an economical price. Aquative-435 foamer is compatible with cationic materials at low pH, anionic materials at high pH, and non-ionics in any pH system.

Application

Because of its unique properties, this foamer provides excellent foam quality and foam half-life in fresh water, brines with <120,000 ppm chlorides, and hydrochloric acid. It is also tolerant of small amounts of hydrocarbon contamination and will foam alcohol-water mixtures up to 50% alcohol.

Features and Benefits
  • Effective in foam fracturing, foam acidizing, and removal of formation fines in post treatment fluids
  • Provides excellent foam quality

Application

A high temperature stable foamer for high brine conditions, such as gas well deliquification, completion fluids, and drilling fluids.

Features and Benefits
  • High Brine Tolerance
  • Thermal Stability >200°C
  • Compatible with Anionics, Nonionics and Cationics
  • Foam Booster for High Brine

Aquative-911VS®

High-temperature viscoelastic surfactant

Description

Aquative-911VS is a patented viscoleastic surfactant (VES) that offers a range of unique benefits when used in acidizing of hydrocarbon-bearing carbonate reservoirs.

Application

Aquative-911VS can provide enhanced wormhole network development during carbonate reservoir acidizing, particularly at high temperature, without causing significant face dissolution. It can also be used as a diverting agent for optimized stimulation performance in multistage acidizing treatments of high perforation length wells, particularly horizontal wells.

Features and Benefits
  • The ability to divert acid at temperatures up to 350°F/180°C during acid stimulation operations
  • The ability to treat lower temperature reservoirs at lower dose of VES
  • A product that performs equally as well in limestone and dolomite reservoirs
  • Easy field formulation of a single component viscosifier that blends easily into acid without
  • Viscosifying until neutralized in the reservoir
  • Better iron tolerance than other VES-based systems for acidizing
  • A better tolerance to corrosion inhibitors, a known interference with viscosification in many VES-based acidizing systems
  • Easy clean up of well post acidizing
  • The ability to viscosify many organic acids that can also be used for acidizing operations
  • Enhanced environmental profile
