Petropedia explains Bailing
In simple words, bailing is a cable driven tool used along with the bailers either with hydrostatic bailer or with sand bailer to remove any leftover tool or equipment from deep down the well hole. In order to bring the bailer back to the surface, bailing line is necessary. This bailing line has a mechanism of complete communication with the operators at the surface and provides all inside details of the wellbore. Sometimes, process of using bailers to remove any unnecessary debris, such as drilling mud, sand, water, etc or any leftover tool is called as bailing.
