Integrated Drilling System
IDS vs Conventional
The IDS represent an integration and simplification of conventional well construction elements, enabling the system to be pre-assembled and tested onshore, and pre-installed on location by vessel prior to rig arrival.
Emphasis has been made to allow usage of conventional drilling and well construction material and services for the remaining well construction activity.
