Con-Surf 91
Surfactant / Flow-Back Aid
Product Overview
Con-Surf 91 is a proprietary surfactant blend that is used as a flow-back aid in stimulation treatments. Flow-back aids are usually surfactants or cosolvents added to stimulation treatments to reduce capillary pressure and water blocks.
Flow-back aids are critical in both moderate permeability reservoirs (oil) and low permeability reservoirs (gas). Flow-back of the fracturing fluid is improved by reducing the capillary pressure of the fluid in the fracture region, thus reducing the drawdown to produce hydrocarbon.
Recommended Application
- Con-Surf 91 is generally added to stimulation fluids at concentrations of 2 gpt (gallons per thousand).
- Compatibility testing is strongly recommended.
Features & Benefits
- Easy on-site addition.
- Non-fluorocarbon based.
- Effective at low concentrations.
- Extremely cost-effective.
- Soluble in fresh water, sea water, and most brines.
- Long shelf life.
