PRODUCT USES

SELECT FIZZ FOAM 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.

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

SELECT FIZZ FOAM STICKS can be used to increase the swabbing efficiency and life of swab cups. The extremely 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.

PRODUCT ADVANTAGE

SELECT FIZZ FOAM STICKS are an economical way to remove water from gas wells without using expensive well service operations such as swabbing, jetting and coiled tubing, or installing artificial lift and siphon strings.

TREATMENT DETERMINATION & PROCEDURE FOR WATER REMOVAL

The number of SELECT FIZZ FOAM 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 SELECT FIZZ FOAM STICKS to water above the perforations. Atreatment of ½ to 1 percent by weight would require 1.75 to 3.50 pounds of stick per barrel of water.

SELECT SIZES STICKS PER BBL (INITIAL SLUG TREATMENT)
JUNIOR (1-1/4”X15”) TO 4 STICKS PER 1 BBL OF WATER

NOTE

This 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 rate until the most economical point is reached. Periodic treatments with SELECT FIZZ FOAM STICKS may be necessary to prevent production decline due to gradual water build-up. It is much easier to maintain gas production with regular insertion of SELECT FIZZ FOAM 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 SELECT FIZZ FOAM STICKS to provide additional agitation energy.

THE MOST COMMON PROCEDURE

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 top of fluid) flow well about 25 percent 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.

PRODUCT SPECIFICATIONS

The stick will normally dissolve in 20 to 80 minutes depending on temperature, salt content and relative water motion. SELECT FIZZ FOAM STICKS are virtually soluble in water and insoluble in oil. The melting point of the stick is 122 degrees Fahrenheit. The stick will dissolve in water in wells with BHT below 122 degrees (just at a slower rate). Lab tests indicate the dissolving rate in 50,000 PPM moving brine water to be 35 minutes @ 100 degrees, 15 minutes @ 120 degrees, 5 minutes @ 140 degrees and 1 minute @ 180 degrees. The dissolving time will decrease if the sticks are broken before dropping or if they break upon impact with the top of the fluid. The specific gravity is 1.1. 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.

CAUTION

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