XMAX
Unique water shut off technology
Page last modified
March 14 2023
Unwanted water production is one of the biggest challenges when optimising hydrocarbon production from a well. Aubin has developed XMAX to enable water shut-off downhole, improving field economics and creating value for operators.
XMAX offers an easy-to-deploy solution for zonal isolation, creating a permanent barrier in the reservoir. By placing the barrier within the reservoir, issues such as water bypass and coning can be delayed or prevented, and the full wellbore diameter is maintained following treatment, offering a significant advantage for potential future wellbore operations. XMAX uses environmentally acceptable components and is deployed using established techniques similar to those used for scale squeezes, acid stimulation, or other chemical treatments, making it a low-risk solution for water shut-off.
