HA-FWF Sticks were designed to be used in shallow gas wells with low bottomhole temperatures. They are fast acting sticks and will dissolve in cold fluids where other sticks require more time to dissolve. HA-FWF Sticks are primarily used to remove water from gas wells and increase gas production. This foaming action decreases the hydrostatic back-pressure which increases gas production that further enhances the foaming action until the well unloads.

HA-FWF Sticks can be used to remove condensate and water from gas condensate wells and flowing oil wells. For wells with more than 75% condensate, it is recommended to use OIL FOAM STICKS.


HA-FWF Sticks contain 100% active powdered 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.

HA-FWF 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 HA-FWF Sticks used is based on the volume of water above the perforations. Field tests indicate that the best results were achieved by using a larger initial slug treatment of 1/8 to ¼ percent by weight of HA-FWF Sticks to water above the perforations. A treatment of 1/8 to ¼ percent by weight would require .44 to .88 lb of stick per BBL of water.

SizesSticks per BBL (Initial Treatment)
1 1/4″ x 18″1/2 to 1 Stick per 1 BBL of water
1 1/4″ x 15″1 to 2 Sticks per 1 BBL of water
3/4″ X 15″2 to 4 Sticks per 1 BBL of water


The above amount is recommended for an initial slug treatment. In many cases, removing the top few hundred feet of fluid may be sufficient to allow the production of natural gas to blow out the remaining fluid in the well. To determine the optimum amount for periodic treatments you may choose to gradually reduce the initial treatment amount until the most economical point is reached. Periodic treatments with HA-FWF Sticks may be necessary to prevent production decline due to the gradual water build-up. It is much easier to maintain gas production with regular insertion of HA-FWF Sticks than it is to kick off a dead well. Gas bubbling though water is necessary to create foam. If a well is totally dead, GAS STICKS may be used in conjunction with HA-FWF Sticks to provide agitation energy.


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 dissolved) flow well at about 25% of pretreatment rate for about 30 minutes or until foam reaches surface then return to normal rate. FOR SHALLOW OR LOW RATE WELLS leave well flowing while dropping sticks.

The estimated hydrostatic back-pressure reduction for each BBL of water removed (for various tubing sizes) is shown below: (Based on .43 PSI per foot of depth)

2 3/8 inch100 PSI Reduction for 1 BBL of water removed
2 7/8 inch75 PSI Reduction for 1 BBL of water removed
3 1/2 inch50 PSI Reduction for 1 BBL of water removed


HA-FWF Sticks are a powdered foamer in a water soluble tube so the foamer is released as soon as the tube starts to dissolve. This gives a quick foaming action in shallow gas wells with cold fluid. Also, since the foamer is in a powdered form, no hardners are required leaving more active content in each stick.


As with all industrial chemicals, contact with eyes or skin should be avoided. Wash thoroughly with water. Sticks should be stored in a cool dry place. Read MSDS sheet before using. Always remove stick from plastic bag before using. Bag can be used as a glove to avoid contact.
