Blowout Sticks


BLOWOUT 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.

BLOWOUT STICKS™ can be used to remove fluid from gas-condensate wells and flowing oil wells. For gas-condensate wells with more than 75% condensate, it is recommended to use OIL FOAM STICKS™ in conjunction with BLOWOUT STICKS™.

BLOWOUT STICKS™ are used to increase the swabbing efficiency and life of swab cups. The slick coating along with the foaming action increases efficiency and life of the swab cups and allows the well to flow easier. The perforations are often cleaned as a result of the surfactants and swabbing action.

BLOWOUT STICKS™ are used in water injection wells in combination with ACID STICKS® to help reduce injection pressures. Surfactants contained in BLOWOUT STICKS™ can help remove oil coating on scale. This helps the ACID STICKS® react with the exposed scale.


BLOWOUT 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 BLOWOUT STICKS™ to be 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 ½ to 1 percent by weight of BLOWOUT STICKS™ to water above the perforations. A treatment of ½ to 1 percent would require 1.75 to 3.50 lb of stick per BBL of water

SENIOR (1 5/8” X 18”)1 to 2 Sticks per 1 BBL of water
JUNIOR (1 ¼” X 15”)2 to 4 Sticks per 1 BBL of water
THRIFTY (1” X 15”)3 to 6 Sticks per 1 BBL of water
MIDGET (5/8” X 15”)8 to 17 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 BLOWOUT 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 BLOWOUT STICKS™ than it is to kick off a dead well. Gas bubbling through water is necessary to create foam. If a well is totally dead, GAS STICKS™ may be used in conjunction with BLOWOUT STICKS™ to provide agitation energy.


Shut-in the well and drop sticks through a lubricator. Wait 45 seconds or until sticks contact top of fluid 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 20 minutes or until foam reaches surface then return to normal rate. FOR SHALLOW OR LOW RATE WELLS leave well flowing while dropping sticks if possible.


The stick will normally dissolve in 20 to 80 minutes depending on temperature, salt content, and relative water motion. BLOWOUT STICKS™ are 100% soluble in water and insoluble in oil. The melting point of the sticks is 122ºF. The stick will dissolve in water in wells with BHT below 122º (just at a slower rate). Lab tests indicate the dissolving rate in moving 50,000 PPM brine water to be 72 minutes @ 100º, 25 minutes @ 120º, 8 minutes @ 140º, and 3 minutes @ 180º. The dissolving time will decrease if the sticks are broken before dropping or if they break upon impact with the top of the fluid. Specific gravity is 1.11. Falling rate through fresh water is approximately 100 feet per minute. The sticks can free fall (through air) 3,000 feet in about 15 seconds. Gas moving up tubing will often change falling characteristics.




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. Always remove stick from plastic bag or paper tube before using. Bag or tube can be used as a glove to avoid contact with hands.
