More Gas At Less Cost.

Water accumulates in oil and gas wells as they age, preventing the oil and gas from rising. To maximize the field life and oil and gas production of the well, the water must be extracted or altered to allow oil and gas production to resume.
Method of allowing oil and gas to flow freely again is to add a surfactant to the water, converting the liquid into foam.
Foam Sticks

This is used to remove water from oil and gas wells and increase production. Foaming action decreases hydrostatic back-pressure which increases oil and gas production that further enhances the foaming action until well unloads.

Advantages
Foam sticks contain 100% active foamer in a water soluble tube that can produce up to 4 times more foam. The entire sticks are soluble, and are shipped ready-to-use and will not dissolve while in cool dry storage.
Sticks can develop foam in high temperature deep gas wells. Stable foams can be developed at 212 Deg.F and above. Formulation can be altered for extreme temperatures.

Foam sticks are economical way to remove water from oil and gas wells without using expensive service operations such as swabbing, jetting with coiled tubing, or installing artificial lift and siphon strings.

Sticks will normally dissolve in 30 to 90 minutes depending on temperature, salt content, relative water motion.

Treatment Determination
This is based on volume of water above the perforations. If wells are flowing, we recommend (fluid on well data) 8 to 10 sticks per 100 bbls produced water per day, ideally, split treatment as follows;
• Drop half the amount of the sticks in the morning
• The other half of the required sticks in the evening to provide a longer unloading effect over 24 hour period.

Helpful, But Not Required
Shut in well for 30 to 60 minutes after dropping the sticks to allow sticks to completely drop to the bottom of the well and dissolve, as well as allowing the bottom hole pressure to build up.

IF AFTER WELLS HAVE BEEN SHUT-IN then slowly open wellhead valves to 25% flow capacity, until fluid starts hitting the surface. When fluid starts hitting the surface, then slowly open the well head flow valves to 100% flow capacity and let the well heads unload as much fluid as possible. Perform treatment 2 to 3 times per day for a couple of days to unload the fluids downhole and build up back in the formation.

After a couple of days when wells start to show a consistent optimum flow rate, then start decreasing the total number of sticks to be dropped by 50%.
