AF – DELUX STICK
AF-DELUX STICKS are special sticks that contain 100% active surfactants, friction reducer, and foam stabilizer in water soluble tubes. Natural gas bubbling through the water column and 100% active ingredients produces foam which can help remove water from watered-up gas wells.
AF-DELUX STICKS are primarily used to remove water from gas wells and increase gas production. The foaming action decreases the hydrostatic back-pressure which increases gas production that further enhances the foaming action until the well unloads. AF-DELUX STICKS can be used to remove fluid from gas-condensate wells and flowing oil wells. For wells with more than 75% condensate, it is recommended to use AF-BLUE CONDENSATE STICKS.
AF-DELUX STICKS contain 100% active foamer in a water soluble tube that can produce up to four (4) times more foam than some other sticks on the market. The entire stick (tube, caps, and contents) are water soluble. The sticks are shipped ready-to-use and will not dissolve while in cool dry storage. AF-DELUX STICKS can develop stable foam in high temperature deep gas wells. Lab tests indicate that stable foam can be developed at 212°F and above. Fore extremely high temperatures wells the formulation can be altered. AF-DELUX STICKS are an economical way to remove water from gas wells without using expensive well service operations such as swabbing, jetting with coiled tubing, or installing artificial lift and siphon strings.
The number of AF-DELUX STICKS to be used is based on the volume of water above the perforations. Field test indicate that the best results were achieved by using a larger initial slug treatment of 1/8 to 1/4 percent by weight of AF-DELUX STICKS to water above the perforations. A treatment of 1/8 to 1/4 percent by weight would require .44 to .88 lb of stick per BBL of water.
The most common procedure is to shut-in the well and drop sticks through a lubricator. Wait 30 minutes until sticks dissolve then slowly return well to normal production. Repeat procedure if or when it becomes necessary. FOR HIGH RATE WELLS (after sticks have contacted the top of fluid) flow well at about 25% of pretreatment rate for about 30 minutes or until foam reaches surface then return to normal production. FOR SHALLOW OR LOW RATE WELLS leave well flowing while dropping sticks if possible.
The sticks will normally dissolve in 30 to 90 minutes depending on temperature, salt content, and relative water motion. The melting point of the sticks is 125°F. The stick will dissolve in water in wells with BHT below 125°F (just at a slower rate). Lab tests indicate (tube & contents) will dissolve in 90 minutes at 100°F, 62 minutes at 120°F, 45 minutes at 140°F, and 30 minutes at 180°F. The specific gravity is 1.16. The falling rate through fresh water is approximately 100 feet per minute. The stick can free fall (through air) 3,000 feet in about 15 seconds. Gas moving up tubing will often change falling characteristics.
Sticks are packaged in plastic chests, plastic tool boxes,
cardboard cartons and drums.
