Title: An assessment of subsea production systems
Author: Devegowda, Deepak
Abstract: The decreasing gap between technology and the it ?s applicability in the oil industry has led to a rapid development of deepwater resources . Beginning with larger fields where the chances of economic success are high , to marginal fields where project economics becomes a more critical parameter , the petroleum industry has come a long way . However , the ever growing water depths and harsher environments being encountered are presently posing challenges to subsea production . Being able to develop a field and then proceeding to ensure flow for the life of the field comprises many situations where the production equipment can fail and falter or through external factors , be deemed unavailable . Some of the areas where most of the current developments in subsea production are being seen are in subsea processing , flow assurance , long term well monitoring and intervention technologies ? areas that pose some of the biggest challenges to smooth operation in the deepwater environment . This research highlights the challenges to overcome in subsea production and well systems and details the advances in technology to mitigate those problems . The emphasis for this part of the research is on multiphase pumping , subsea processing , flow assurance , sustained casing pressure problems and well intervention . Furthermore , most operators realize a reduced ultimate recovery from subsea reservoirs owing to the higher backpressure imposed by longer flowlines and taller risers . This study investigates the reasons for this by developing a global energy balance and detailing measures to improve production rates and ultimate recoveries . The conclusions from this energy balance are validated by simulating a deepwater field under various subsea production scenarios .
