AbstractIn an effort to improve well production performance targeting recent increases in oil demand, Saudi Aramco implemented several innovative technologies and practices in its offshore assets in the Arabian Gulf. The identified challenges which followed past practices were focused on enhancements to existing well completions, chemical treatments of damaged wells, implementation of Smart field technologies and early detection of casing leaks to enhance wellbore integrity and meet environmental standards. This paper describes the methodologies of four technologies which were tested and implemented in three major offshore fields in Saudi Aramco. These technologies are the use of passive inflow screens combined with swellable packers in horizontal sidetracked wells to prevent premature water or gas encroachment, smart in-situ gas lift completion which utilizes the reservoir gas cap for artificial lift of oil wells, the chemical treatment of wells which endured formation damage and the utilization of a modified ultrasonic tool for early casing leak detection in aged wells equipped with up-hole packers.
