WORK HISTORY
Principal Reservoir Engineer @Enquest
Aberdeen, GB
Started as Principal Reservoir Engineer on the Kraken heavy oil field, working closely within an integrated team to develop the current generation dynamic model of the field, which for the first time achieved a well-by-well watercut and pressure match. The model remains in use to support reserves position and has been further used to screen for infill opportunities that are currently being progressed. Since the start of 2021, transitioned into Principal RE / Team Lead for EnQuest’s Bressay heavy oil development. In the process of finalising our suite of subsurface models that capture the uncertainty of this complex field across a range of development options.
