Integrated Multizone Low-Cost Intelligent Completion for Mature Fields

Abstract

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractA well equipped with downhole flow control and monitoring devices provide tools to manage reservoir and well performance. Many optimization techniques have been applied in conjunction with commercial reservoir simulators with detailed multisegment well model to improve ultimate recovery. It is important to know that all the benefits of the reservoir optimization can be lost if the availability and appropriate control of the artificial lift is not used. A well equipped with three on-off type flow control valves and four pressure and temperature optical transducer: one for each zone plus one more above the production packer in combination with a rod-pump control with moderate service condition specifications is described. Standardization of the connectivity between automation of the intelligent completion and artificial lift is necessary for a vendor-independent integration, which becomes more costeffective by using open industry standard protocols. This also allows the use of different supervisory software, reducing the impact of changing systems already in use without losing the flexibility of choosing a solution that has some custom features or that are cheaper. This paper will discuss both the benefits resulting of the integration between intelligent completion and artificial lift automation. The value added to provide better decision making to respond immediately to unexpected changes, the need of satisfy reliability demands of the operational people and the issues involving the use of intelligent completion in mature fields.

Enhanced Oil Recovery: An Update Review

“… Carmópolis is an onshore heavy oil (22 °API) reservoir with reported in situ-combustion (1978)(1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988)(1989), polymer flooding (1969-1972 and 1997), steam injection (1978) and microbial EOR or MEOR (2002) pilot projects. The field has been developed mainly by waterflooding [27,[31][32][33][34]).  Karazhanbas is an onshore heavy oil (19 °API) reservoir with documented polymer flooding [35], steam injection [36,37], in-situ combustion and in-situ combustion with foam injection as conformance strategy [37,38]).…”
