1.1 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.
1.2 This bulletin provides an overview of components that can be considered for future research into developing an automated well control actuation system, such as:
a) top drive;
b) hook load weight indicators;
c) drawworks;
d) mud pumps;
e) blowout preventers (BOPs);
f) BOP control system (closing unit);
g) internal BOP and/or full-opening safety valve;
h) choke manifold;
i) logic solvers;
j) pressure control valve (pilot valve);
k) surface and downhole blowout preventer;
l) pipe tallies;
m) managed pressure drilling equipment;
n) open and closed channel fow meters;
o) pit level sensors.
1.3 To the extent that this document reviews specifc equipment arrangements, it is recognized that other arrangements can be equally evaluated in addressing well requirements and achieving safety and operational efciency.
