What are completion fluids used for?

Completion fluids are specifically designed to be used in the process of completing a well after the drilling phase has been finished but before the well is put into production. These fluids play a crucial role in preparing the well for extraction of oil or gas by ensuring the wellbore is stable, controlling pressures, and preventing the influx of formation fluids. They help protect the wellbore integrity, facilitate the installation of completion equipment, and ensure that the well is ready for production.

Using completion fluids can also assist in cleaning the wellbore and removing any residual drilling fluids or debris, which is vital for ensuring that the production can occur efficiently and without complications. This makes their use critical in the final stages of well development to ultimately maximize productivity and safety during the production phase.
