Intelligent automation of mature field development process. Case study from the Romashkinskoe field block(PPT)

摘要

Digital Field technology has become the standard for green field development in the industry and brown fields are only in the progress toward it. OAO TATNEFT started intelligent automation pilot on the 3 block of Berezov sector in November 2009. It is a marginal field and has been under development since 1962. At start of the project overriding objectives were to stimulate production and reduce OPEX. For this purpose in the scope of the project were included: 1. tracers injection and reservoir simulation; 2. pressure transient analysis of data from permanent downhole gauges; 3. automation of production wells and crosswell water injection system; 4. intrawell water separation; 5. renewable energy usage for injection well control equipment. Intelligent automation of mature field development process allowed to achieve following results: 1. exploration rate of field was maintained on the same level; 2. number of current workovers were reduced by 54 %; 3. formation pressure was increased by 4,9 % and watercut decreased by 4,3 % with an injection rate maintained on the same level. The case study in this paper addresses results of 3 years experiment, challenges we faced with and distinguishing features of brown field intelligent automation strategy.
