A 3-step approach to effective training can help tame unpredictable nature of HPHT environments, wells, kicks

摘要

OVER THE PAST few years, Aberdeen Drilling School (ADS) has conducted dedicated HPHT training for challenging wells around the world, in the UK sector of the North Sea (Conoco Phillips, Shell UK and Talisman Energy), the Azeri sector of the Caspian Sea (BP, JAOC), Egypt (BP, BG/Rashpteco, ENI), Norway (Statoil, ENI Norge, Norske Shell), Canada (Canadian Superior), India (Transocean, Reliance, GSPC) and Nigeria (Shell). The difficulties and hazards associated with drilling in HPHT environments are universally recognised in the industry. The unpredictable nature of the kicks and the speed at which a well can become under balanced requires that drillers accept a new philosophy. The key to preventing an HPHT kick is to create an atmosphere within the operation - especially at the rig site - that enables and motivates the team involved to concentrate on the small changes in surface response during the drilling of the transition section through to the target sections.
