Background
An operator in Alberta, Canada had a number of multiwell pads to complete that included the milling of debris subs. A service rig was replaced with an efficient equipment package and the implementation of CoilTOOLS coiled tubing intervention tools and solutions provided by Coil Tubing Services. A one-piece CT unit and support crane reduced the operational footprint and enabled a faster, more-efficient rig-up due to minimal equipment repositioning between wells on a pad. The milling tools eliminated a venturi junk basket run and the expertise of the minimized crew improved the cleanout efficiency, resulting in additional savings of time and money.
