PRODUCT USES

FLURO-STICKS are primarily used to increase gas production by removing condensate, hydrocarbons and water from gas-condensate wells. The foaming action decreases the hydrostatic back-pressure which increases gas production which further enhances the foaming action until the well unloads.  Some water must be present to enhance the FLURO-STICKS foaming action in wells with BHT less than 130ºF.

FLURO-STICKS are recommended only when over 75% of fluid column is composed of condensate/hydrocarbon.  If the fluid column contains over 25% water, it is recommended to use SLICK STICKS only or a combination of both FLURO-STICKS and SLICK STICKS to be more effective in removing the fluid.

FLURO-STICKS can be used to increase the swabbing efficiency and life of swab cups. The slick coating and foaming action increases efficiency of the swab and extends the life of swab cups.  The perforations are often cleaned as a result of the detergent and swabbing action. PRODUCT ADVANTAGES FLURO-STICKS are an economical way to remove condensate/hydrocarbons and water from gas-condensate wells without using expensive well service operations such as swabbing, jetting with coiled tubing, or installing artificial lift and siphon strings.

TREATMENT DETERMINATION & PROCEDURE FOR FLUID REMOVAL

The number of FLURO-STICKS to be used is based on the volume of fluid 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 FLURO-STICKS to fluid above the perforations.  A treatment of ½ to 1 percent by weight would require 1.75 to 3.50 lb of stick per BBL of fluid.

THE MOST COMMON PROCEDURE

The most common procedure is to 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 30 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 30 to 80 minutes depending on temperature, salt content, and relative fluid motion. Melting point of the sticks is 130ºF.  The stick will dissolve in water in wells with BHT below 130º (just at a slower rate).  Lab tests indicates that the dissolving rate in moving diesel to be 80 minutes @ 100º, 24 minutes @ 120º, 7 minutes @ 140º, and 2 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.  The specific gravity is 1.08.  The falling velocity through fresh water is approximately 100 feet per minute. Gas moving up the tubing will often change falling characteristics.
