The drilling rig in each region or company should have specific shut-in procedures for Drilling and Completions activities to which the rig or workover unit will be exposed.

Shut-in procedure subjects may include the following:

  • Drilling (milling/circulating for cased hole)
  • Tripping (with both drillpipe and drill collars across the BOP stack)
  • Open hole (out of the hole) operations
  • Wireline operations
  • Running tubulars (casing/tubing)

For subsea stack operations, the operations folks should ensure that each rig has a specificc procedure for identifying and hadling gas in the riser and BOP.

A hard shut-in would require the following steps:

  • Hydraulically operated BOP stack choke and kill valves to be in the closed position
  • Valves on the choke manifold not in line with normal flow routing to be closed
  • Valves on the choke manifold in line with flow or pressure sensor to be opened
  • The remote choke to be closed
