Drilling: Dilution Based Dual Gradient Drilling
The dilution based dual gradient drilling system concept and development work started in 2002. A dual gradient drilling system improves well safety by restoring kick margins and drilling with enhanced kick detection. It improves well efficiency by using less casing and liner strings, a larger hole size at well TD and earlier and more production. It reduces risk for both exploration and development wells.
Dual gradient drilling is not only for deep water wells it can also be used for platforms, spars and jack up wells. Dual gradient combined with managed pressure drilling is safer and reduces drilling time. This presentation describes the benefits of a dual gradient drilling system, the applications and advantages.
