Early Production Systems

This article summarizes development of the Azurite field as a way of providing context for evolution of the Floating, Drilling, Production, Storage and Offloading (FDPSO) concept. It also reflects on the project’s technical and economic drivers that led the Azurite project team to select the FDPSO concept. The paper also highlights other application for FDPSOs and discusses some of the key variables that determine the suitability of the FDPSO concept for use in field developments. The step change in economics afforded by the incorporation of a drilling rig onboard a conventional FPSO brings new hope to fields of similar geometry and in similar environments that heretofore were considered marginally economic or uneconomic. The FDPSO concept also has application as an early production system, in advance of full-field developments. The concept has tremendous potential as a ‘game changer’ for field developments, whether it is employed to unlock the value of marginal fields in deepwater – even in a low oil price environment – or as an early production system. As the concept employs a drilling rig onboard the vessel, traditional challenges regarding deepwater drilling rig day rates and availability are eliminated.

Floating early production systems (FEPS) are becoming more important to the successful exploitation of Australia's deep water oil and gas. Importantly, FEPS help oil and gas operators reduce deep water full field development risk, as uncertainty in the reservoir characteristics are reduced by obtaining dynamic data (that is, partially producing some of the reservoir). This paper will present a review of existing FEPS that are now in use or have previously been in use worldwide and will discuss where they are headed in the future. The paper focuses on: The selection of the floating and subsea-vessel, mooring, riser, mechanical connection, etcetera; Technology presently available; and, Addressing the requirements in situations where new floating and subsea technology is needed. The qualification limits of existing technology will be discussed in the context of what systems are ready and off-the-shelf for operators to make use of now. The choice of appropriate FEPS will be discussed as a function of: proximity to pipeline infrastructure, potential production rate, capability to re-inject associated gas, prevailing variation in year-round environmental conditions, waterdepth, and, geotechnical description of sea bottom. A high level conceptual case study showing typical costs for the implementation of a deep water FEPS will be presented as a way of understanding the potential upside and downside exposure for an operator considering undertaking a deep water FEPS program.

Early Production

Screening is one of the main filtration and separation methods for unconsolidated sandstone reservoirs, and the problem of failure of sand control screen, encountered by some sand control wells in early production phase, gives rise to serious sand production in the shaft and influences normal production in the oilfield. In order to analyze the reason for screen failure in sand control wells and the detailed mechanism of the short service cycle of sand control screens, this paper proposes an experimental device, which can simulate sand screen erosion by the sand-laden slurry under underground working conditions and studies the influence of screen type, salinity, sand particle size, sandladen concentration, erosive angle, and other factors on the degree of erosion of screen filtering medium. Based upon experimental results, the current study establishes a model for predicting the service-life of sand control screens. The results showed that the jet velocity, sand-laden concentration, sand particle size, erosive angle, and other factors exhibited an obvious influence on the erosion of screen, while the salinity of formation water exerted an insignificant influence. Under the same conditions, different types of screens presented relatively significant differences in antierosion performance, whereas the anti-erosion performance of the stars screen was found to be superior to that of the metal mesh screen. The results provide some basis for selecting sand control methods, offering guidance about the production systems and predicting the service-life of screens.
