The multiple role of unconventional drilling technologies. from well design to well productivity

摘要

This paper deals with new drilling technologies and is focused on their ability to reduce capital expenditure per barrel produced. During the last decade, they have greatly contributed both to improve production and reserves but also to decrease operational costs. TOTAL has been involved in these unconventional technologies all over the world and has used them for numerous original applications *ERD to reach offshore reserves from onshore facilities (Argentina), * ERD to test a marginal panel from existing offshore facilities (North Sea), * Multilaterals to explore and delineate a blind zone (Libya), to improve production and to increase reserves (Libya, North Sea) or to revitalise a mature field (Middle East).
