High Quality Content by WIKIPEDIA articles! Snake Wells is a term used by Shell Oil to refer to a series of oil wells drilled in the Champion West oil field offshore Brunei. The wells used a combination of technologies including extended reach drilling, swellable wellbore packers and remotely operated zonal isolation and control. The directional drilling technique allows the path of the well to be directed to achieve contact with as many potentially producing features as possible. This results in a "snake like" well path which weaves up and down through multiple geological features in order to achieve maximum reservoir drainage.
