The Challenge
Canacol together with the engineering company A.B. Projects had the mission of creating new wells for gas extraction and transporting it for distribution in Cordoba, Colombia.
Due to the high pressure for the gas transportation (above 100 bar) the client used Flexsteel (flexible pipes made of layers of polyethylene and steel). Additionally, at the exit of the wells, the gas had to be separated from the water that was underground through a turbine. But the separated water still contained traces of gas and minerals that needed to be treated once again.
Pexgol Solution
Canacol and A.B. wanted to use a reliable pipe to carry out the separation of water from surplus gases and minerals, but having used the Flexsteel pipe would have incurred on excessive expenses. Therefore they selected Pexgol thanks to its possibility of supply in long lengths, its high levels of safety and its low installation cost (versus other materials for high and low pressures).
The 11 km of pipe were installed in just one week: the uncoiling and laying of the pipes took 3 days and then the joints were connected by electrofusion and the pipes buried.
Pexgol proved once again to be an excellent solution for oil or gas wells where it is required to transport water for treatment with pressures that are below 30 bar.
