Principles and Methods for Optimization of Offshore Cluster Well Platform

Optimization of the location of the offshore cluster well platform is one of the key issues in drilling technology, influencing directly the benefits of the whole oilfield. In order to reduce investment and the risk of drilling operations, by combining with geology, reservoir and engineering, the factors influencing the optimization of the location of offshore platform and method for optimization of the location of offshore platform have been summarized. Finally, with optimization of the location of offshore platform in BZ19-4 oilfield as an example, the principles and methods for optimization of the location of offshore platform has been introduced, which provide valuable experience for the implementation of similar offshore projects.
