High expansion, liquid surfactant blend with high flash point
AQF-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
% by Volume | Amount/100 gal | Amount/bbl | Liters m³ |
0.5 – 2 | 0.5 – 2 gallons | 0.85-3.4 quarts | 5 – 20 |
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. |

Injection Slurry | Water (gallons) | QUIK-TROL GOLD polymer (pounds) | EZ-MUD liquid polymer (pints) | AQF-2 foaming agent (% by volume) |
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.
