State-Of-The-Art Of Ultra Deepwater Production Technologies

Abstract

For the past decade, technology innovation and application have helped to significantly reduce the cost of exploring and producing oil and gas, proving the value technology can bring to the industry. Now while more discoveries are found in ultra deepwater, there is a push to lower CAPEX and OPEX while continuing to produce. This challenge, for both operators and suppliers, compels collaboration and cooperation for improving reliable and innovative technologies including: − Flow assurance technology − Subsea processing − Floating structures − Flowline and pipeline − Risers and umbilicals This paper summarizes some of the results of several recent JIPs on ultra deepwater field development technologies. A review of emerging and existing technologies for deepwater development is presented, which would be of particular interest to technology development personnel and asset team personnel who are in the appraisal or concept selection stages of a project.

Development of marine hydrocarbon resources using underwater production systems

“…However, the use of offshore platforms for this purpose may turn out to be insufficient, or have certain obstacles, due to which production may be not profitable [2]. Insufficient autonomy, difficult climatic conditions (ice cover, strong wind loads), big sea depth, complexity of equipment for monitoring and repair, corrosive effects of sea water and other aggressive environments, high cost of platforms and sea drilling -these and many other factors make a challenge for engineers from all over the world to come up with a unique, innovative solution for the development of offshore fields [3].…”

Otimização dos flutuadores de risers com catenária em configuração complexa

“…Os principais problemas estão relacionados ao excesso de tração no topo, uma vez que todo o comprimento suspenso do riser é sustentado pelo ponto de conexão com a plataforma, e à baixa vida útil à fadiga, principalmente na conexão de topo e no ponto de contato com o solo (touch down point -TDP) (BELL; CHIN; HANRAHAN, 2005).…”

Materials and Corrosion Trends in Offshore and Subsea Oil and Gas Production

“…3 Although there is not a universal definition differentiating between conventional and unconventional fields, in the context of this publication, unconventional reserves are those that require new materials, design methodologies, and technologies. The most challenging reserves often present high pressures and high temperatures (HPHT), can be in deep-waters (i.e., water depths greater than approximately 800 to 1800 m) or in Arctic regions.…”

“…The most challenging reserves often present high pressures and high temperatures (HPHT), can be in deep-waters (i.e., water depths greater than approximately 800 to 1800 m) or in Arctic regions. 3,4 Developing HPHT, deepwater, and Arctic prospects at a competitive cost and acceptable risk level is one of the most complex engineering challenges ever faced by the O&G industry.…”
