In the gas field of Zuidwal, situated in one of the most environmentally sensitive areas of the Netherlands, a total of nine wells were drilled, three of which were horizontal. Due to the nature of the location, and its gas-bearing formation with layers of different reservoir characteristics, the operator adopted special programs and procedures, which provide the focus of this paper.
