Heavy-Oil Well Testing With an ESP, Offshore UK

摘要

Production from heavy-oil fields in the UK continental shelf (UKCS) has become possible over the past 10 years. Despite substantial reserves in the UKCS of crudes with gravitiy of 20°API and lower, most of the activity has been exploration and appraisal drilling. The main reason for restricted activity has been high uncertainty of reservoir and fluid properties. A method was developed to find the most-suitable technology for testing these heavy-oil wells by use of an electrical submersible pump (ESP).
