Abstract

This disclosure provides a hybrid well capping stack system that uses a lower ram blow-out preventer (BOP) coupled to a gate valve-based capping stack that has first and second flowlines where the first flowline has a gate valve and the second flowline has a gate valve. At least one of the first and second flowlines is located on the frame to divert a flow of fluid laterally from a central flow axis of a wellbore.
