Designing methods of drilling-out for offshore production wells
T.A. SamadovThe paper presents the terms of project execution on cluster drilling for development and operation of various offshore oil fields. Reviewed offshore oil fields differ from each other by their mode of occurrence. Thus, a part of the first fields lay onshore, and the other one – offshore in certain depths; the second field is totally located offshore, and the third one is also located deeply offshore. All onshore wells are drilled vertically, the others – directionally. Different drilling options are applied for each deposit and each option is designed via the method reviewed in the references, i.e. total investment is calculated for each option for the drilling of all wells and construction of fixed platforms and piers; the optimal is the option for which the minimum total investment is obtained.
