This is a study on how subsea processing be the enabling technologies for future ultra-deepwater field developments and long distance tiebacks. This study identifies the gaps that need to be closed and decision making process during the field development life cycle by considering both the technical and economic constraints of various subsea processing technologies. As E&P companies continue to explore for oil & gas deeper and further into sea, the challenges associated with developing the deepwater fields are bound to escalate. Subsea processing technologies are the fastest growing technologies due to their huge potential to increase recoverable reserves and to accelerate production. It also enables for cost saving by moving some of the traditional topsides processing to seabed. As the reliability of subsea processing equipment is increasing, the industry is gaining more confidence in subsea processing. As industry gains more experience of design and operating subsea processing technologies, and closing the gaps, it improves understanding of the technology and making advancement to counter the challenges associated with harsher environments and complex fields. Properly-designed modularized compact subsea processing kits can be economic to deploy, and may potentially become an enabler for certain types of marginal field developments.
This paper addresses the challenges of reservoir characteristics and fluid properties, cost, risk, reliability, operability, installability, maintainability and intervention complexities; assesses the existing and emerging technologies; focuses on improving efficient compact design to reduce bulky and heavy equipment, achieving separation from heavy oil, and disposal of separated water. Certainly there are limitations in making the subsea processing viable and accessible to all operators but the technology needs and industry collaboration should overcome these challenges. Also there are opportunities for improvement and standardization, and modular design processing systems for reservoir suitability, field layout and topsides support.
