Economic Considerations

This paper discusses the use of floating production systems (FPS) in developing offshore fields and includes consideration of related system and subsystem options. The system options are discussed from their relative technical and economic merits. Proven conventional and state-of-the-art technology as well as technical limitations are included. A decision tree matrix has been developed for use in the early planning stages to assist in determining preferred baseline options for selecting an approach. Systems from the mud-line upwards to the floating hull, and on-board systems, are included.

Subsea production systems have been an accepted method of developing offshore oil and gas fields since the installation of the first subsea trees in the early 1960s offshore California. Generally subsea completions have been done from floating drilling vessels on wells with subsea wellhead equipment. A number of wells have been completed subsea by bottom supported jackup rigs on wells drilled using mudline suspension equipment. The subsea completion equipment and methods utilised to adapt mudline suspension wells for a subsea production tree are described. This method of completion offers important benefits as it allows completion of wildcat or delineation wells, it can be used in areas of small, scattered reservoirs, and it can be used in conjunction with floating production systems. The cost associated with these subsea completions is roughly equivalent to those of standard subsea completions from floating vessels. An overview of a typical completion system is presented and compared.

Abstract Offshore oil and gas platforms are among the largest structures humanity has ever built. There are more than 7,500 of them towering up from seas all over the world, according to some recent estimates. As wells dry up and pumping equipment wears down, those structures are likely to become obsolete in the upcoming decades. Those oil wells will have be decommissioned and capped off and the platforms taken down. But taking down an offshore oil platform and the tower that supports it is no simple assignment. It is a massive engineering project that requires state-of-the-art equipment.

Offshore Oil

Offshore oil and gas production is now reaching to great depths, in excess of 1000 m, in the Gulf of Mexico and the Campos Basin, offshore Brazil. It will not be long before Australian companies look towards probable reserves in deeper waters that still remain within the Australian exclusive economic zone. Production concepts for deep and ultra deep water thus need to be studied and researched, and a constant watch should be maintained on developments around the world in this area.This paper presents two popular, and constantly evolving, concepts for deep water, namely: tension leg platforms (TLP) and spars. Tension leg platforms have been in existence for about 14 years, and are actively sought for deep water by worldwide operating companies. They are vertically moored by means of taut tethers which present interesting motion characteristics and unique hydrodynamic problems. Spar platforms are currently being installed for production purposes. These are large deep draft cylindrical structures moored by catenary or taut spread mooring systems. Physical details, advantages and limitations of both systems are discussed.While many aspects of these production systems are now understood, there are still several unknowns. Deeper waters translate to newer problems. Potential problems of the future are discussed in this paper, and research needs are highlighted.
