ConocoPhillips, the world's largest independent exploration and production company based on production and proved reserves, has significantly improved offshore efficiency and reduced operating costs by integrating its operations, changing work processes and building a cutting-edge onshore operations centre (OOC). The new approach has helped to increase the number of activities executed offshore, reduce the number of changes to maintenance plans by 70 per cent and has tripled offshore 'tool time' (the number of hours per shift spent performing productive tasks). Unplanned production trips have improved by almost one third, the backlog of work has been reversed and operating costs have fallen by 17 per cent. In an aim to elevate operations performance across their North Sea assets, back in 2013 the company decided to change their operating model for the UK. The challenge was to integrate all their Central and Southern North Sea operations by the end of that year.
