This paper gives details concerning one of the newest producing fields in the North Sea, West of Shetland development. Examples of the pre-start up design and implementation challenges are dwelt on, as well as the philosophy taken when commissioning the plant and chemical injection facilities. The majority of the paper focuses on the first 6 months of production history and the way in which the management of production techniques was performed and in particular how actual operations differed to the planned and designed specifications.

With production of a 20° API crude, significant operational challenges have been encountered with initial start up being a staged and controlled process. Details are given to the suite of production chemicals required to give complete flow assurance as well as to maintain plant integrity. The onset of water production brings with it a whole suite of different challenges with by far the most difficult being demulsification and this has been given particular attention.
