This article describes the Standard Completion Designs.
Monobore completion
Completion with fullbore access across the payzone, without diameter restrictions (but not necessarily with a constant diameter from top to bottom). The monobore concept optimises the opportunity for well intervention through the Xmas tree, i.e. rig-less, and is applicable to any completion diameter. By working through the Xmas tree, many well intervention operations can be conducted without the need to kill the well and pull the tubing string.
Coiled tubing completion
The development of larger sizes of coiled tubing have increased the application and development of coiled tubing completions and associated hardware accessories, such as Gas Lift Mandrels which can be spooled. The main advantage over conventional tubing is that it can be run quickly into the well without having to make up or break tubing joints and hung off under live well conditions.
Wellhead splitter system
This system allows more than one well to be drilled from a single wellbore with multiple surface, intermediate, and production casing and tubing strings. The Downhole Splitter System is essentially the same as the surface splitter, allowing drilling, casing, and completing more than one well from a single conductor. In both cases each well is independent for service and workover requirements.
