Agbami field is another offshore oil field in Nigeria. It was discovered in late 1998, and it was the second major deepwater oil field discovered off the Niger Delta. The field is located in nearly 1,500 meters (4,800 ft) of water and 112 km off the coast of Nigeria. The field is jointly operated by the Star Deep Water Limited, an affiliate of Chevron, Famfa Oil, an indigenous oil company, Petrobras (Brazil), Statoil (Norway), and NNPC (the national oil company of Nigeria). It produces over 70,000 barrels per day (11,000 m3/d) with peak production estimated to be at approximately 250,000 barrels per day. It produces to FPSO unit which cost over 4 billion US dollars to build (Famfa 2008). It has six subsea production systems each, configured …show more content…

Its reservoirs consist of a 620-million-recoverable-barrels accumulation of a critical fluid made of very light oils up to 53°API and classified as condensate, with well head shut-in pressures up to 400 bars, fluid temperature up to 116°C at wellhead, and very high gas liquid ratio (HGLR). It is not only a giant condensate field, but also a gas field with 1Tcf planned gas export. It produces to an FPSO. It utilizes a passive wet insulation with conventional flowlines to control hydrate since the reservoir fluid has high temperature (Rafin et al. 2008). CHAPTER FIVE COMPARISON OF COLD FLOW BENEFITS WITH OTHER TECHNOLOGIES The overall objective for the Cold Flow Technology (CFT) is to demonstrate an innovative and ground-breaking technology solution which allows: • subsea field developments based on ultra-long cold multiphase, wellstream transport in uninsulated pipelines, • with no heating requirements and no chemical additives, and with, • very simplified subsea equipment and control procedures. In this section, the benefits of cold flow technology concepts described in chapter 3 and chapter 4 will be compared with other traditional technologies employed in oil and gas industry to prevent and manage hydrate and wax plug in subsea flowlines. To successfully compare the benefit of Cold flow with other technologies, the cost estimate and qualitative comparison of the different technologies shall be
