Looking to deliquify a well and maximise production as a result? Our superior range of Aubin® chemical foamers have been cleverly designed to effectively remove downhole fluid build up and bring old gas wells back online.
Gas well deliquification takes place when our chemical foamer is applied to the well, either continuously or via batch treatment. The foamer’s key ingredient of a surfactant creates the necessary amount of foam for the specific requirements and conditions, and is able to effectively unload the liquid from the well.
As the foam reaches higher depths, it expands and creates a greater lift - transferring less hydrostatic head to the material below and encouraging more material to keep flowing up. As a result, this unlocks the ability to restore and increase gas production at a low cost and with minimal disruption, even in challenging operating conditions.
In a project completed in South Africa using an Aubin® foamer, our customer had no usable infrastructure in place on their subsea well and the pressure of the well was completely depleted. They had to spend approximately $1m to install tubulars and nitrogen after the foamer was applied to provide additional gas to lift liquid (which is more expensive than our typical foaming treatment requirements).
Additionally, we supported the pre-qualification of our system, including tests that demonstrated impact on formation through supplying our chemical for third party core flood experiments.
As a result, our customer achieved a huge return on investment of over $15M dollars in recovered hydrocarbon from a previously dead well.
"Using foamers early is key. I recommend using a foamer as soon as your well starts producing water, instead of waiting until the well is depleted or dead. Adding a foamer at an earlier stage will likely give you much stronger results."
“We’re in the midst of an energy crisis, with a real drive to make sure production of hydrocarbons is maximised wherever possible… If you can find a low cost and low risk route for recovering hydrocarbons that have previously been hard to recover, it is definitely the time to try this approach.”
Our core range of foamers have been carefully designed to deliquify a well under a number of conditions, with each variation of foamer suitable for different requirements…

Low or high salinity levels
Can be applied either in batches or continuously
Each have different dosage requirements
A higher performance foaming agent
Can be applied in temperatures of up to 170°C
More effective in a higher condensate cut
