AQF-2

High expansion, liquid surfactant blend with high flash point

AQF2AQF-2 is a high expansion, liquid surfactant blend with a high flash point. AQF-2 foaming agent is an anionic surfactant which can be added to fresh water for air/foam, air/gel-foam, or mist drilling applications.

  • NSF/ANSI Standard 60 certified
  • Elevated flash point for easier shipping
  • High quality, high expansion foam with a consistency similar to shaving foam
  • High stability with excellent retention time
  • Proven product for multi-discipline application

 

APPLICATION

The use of AQF-2 foaming agent promotes or assists with the following:

  • Enhance the efficiency of cuttings removal
  • Increase the ability to lift large volumes of water
  • Improve hole-cleaning capability of the airstream
  • Reduce the sticking tendencies of wet clays, minimizing the risk of mud rings and wall packing
  • Reduce erosion of poorly consolidated formations
  • Drilling in zones with lost circulation
  • Increase borehole stability
  • Reduce air-volume requirement

 

MIXING & HANDLING

Approximate Amounts of AQF-2 Foaming Agent Added to Injection Water

Approximate Product Make-ups for Air Drilling Injection Slurries

Injection Slurry Water (gallons) QUIK-TROL GOLD polymer (pounds) EZ-MUD liquid polymer (pints) AQF-2 foaming agent (% by volume)
Air-Foam Drilling System 100 0 – 1 0 – 2 0.5 – 2
Foam mixing/injection procedure: Add AQF-2 foaming agent to injection water. Inject into the air stream at a rate necessary to maintain hole stability and penetration rate. Increase amount of AQF-2 foaming agent as required to compensate for downhole water dilution.

To build a stiff-foam drilling system: Mix QUIK-TROL GOLD polymer (0.5-1 pound per 100 gallons) or EZ-MUD liquid polymer (1-2 pints per 100 gallons) with water before adding AQF-2 foaming agent. Inject into the air stream at a rate necessary to maintain hole stability and penetration rate.

Gel-Foam Drilling System 100 12 – 15 1 0.5 – 1
Gel-Foam Mixing/Injection Procedure: Mix viscosifier and polymer with water before adding AQF-2 foaming agent. Inject into the air stream at a rate necessary to maintain hole stability and penetration rate.

Notes:

  • Close product container immediately after use to avoid gelling of remaining AQF-2 foaming agent.
  • Foam and effluent must never be discharged into a stream or waterway. It is the end-user’s responsibility to contain foam/effluent, cuttings, and production water. Utilize hay bales, temporary containment ponds or systems to isolate the foam.
