Water accumulates in natural gas wells as they age, preventing the gas from rising. To maximize the life and gas production of the well, the water must be extracted or altered to allow gas production to resume.
One of the most cost efficient methods for enabling the gas to flow freely again is to add a surfactant to the water, converting the liquid into foam. The method in which the surfactant is delivered is fundamental to the cost and labor efficiency.
Aquasol® Water Soluble Paper can be formed into a tube, filled with the surfactants then dropped into a gas well to deliver surfactants to the bottom of the well. The process can be further enhanced by using a Soap Stick Launcher.
In the not too distant past, vast quantities of chemical solutions had to be poured down the well to reach deep, underground sources. This method is inefficient and costly when compared to using the water soluble paper soap stick method.
The melting point of a soap stick is 122°F/ 50°C.
The specific gravity of a soap stick is 1.11.
The soap sticks will normally dissolve in 20 to 80 minutes depending on temperature, salt content, and relative water motion in the well.
The dissolving time will decrease if the soap sticks are broken before dropping or if they break upon impact with the top of the fluid.
