Apparatus and Method for Underbalanced Drilling and Completion of a Hydrocarbon Reservoir

摘要

A system and method for underbalanced drilling and completion of a hydrocarbon reservoir is disclosed. The system prevents formation damage by using a solids-free, non-wetting phase drilling fluid while maintaining underbalanced conditions throughout the entire drilling and completion phase of the operation. By preventing formation damage, this system provides an alternative or supplement to hydraulic fracking.
