SUBSEA AND PLATFORM OPTIONS FOR SATELLITE FIELD DEVELOPMENTS

摘要

As offshore infrastructure matures, satellite field developments are becoming increasingly common. The essential components of a satellite production facility are the well(s), by which reservoir fluids flow to the seabed or surface, and a means of export of the produced fluids. In addition, various auxiliary facilities may be required. These may include: drilling and workover equipment; processing, control and metering systems; and power and utilities to support these operations and ensure their safe performance. These supporting functions may be shared between the host, the satellite and mobile vessels in many ways. Various satellite production arrangements are compared in detail in the paper, utilising a database of North Sea subsea and surface satellites. With satellite developments being employed in ever-deeper waters and over longer step-out distances, prudent selection between subsea or surface options is vital to achieving favourable field economics.
