This bulletin provides a review of the equipment and interfaces to be considered for the automation of a blowout preventer to place the well in a safe state in an onshore environment. It also provides an overview of components that can be considered for future research into developing an automated well control actuation system. These technologies, once fully developed and implemented, can help automate and expand ways to mitigate unexpected events resulting in a loss of primary well control.
This document is intended to address the issues encountered by infrequent freezing events that can occur in moderate climates, and encourages upstream onshore operators to review winterizing programs and integrate appropriate considerations into written facility operating and emergency programs and procedures.
