26、4:2014ISO 13354:2014(E)IntroductionDrilling into shallow-gas-bearing formations is a very delicate and challenging operation. If the drilling operations are seriously complicated by the reduced safety margin available between kick and loss, the situation in case of a gas influx becomes extremely haz
27、ardous, due to a combination of the following adverse factors. Shallow gas flows are extremely fast-developing events; there is only a short transition time between influx detection and well unloading, resulting in a reduced time for the driller to take the right decision, and leaving little room fo
28、r error. Past blowout reports have disclosed the magnitude of severe dynamic loads applied to surface diverting equipment. One of the associated effects is erosion, which adds a high potential for fire and explosion due to flow impingement on rig facilities which gives the gas flow access to various
29、 sources of ignition. Many past shallow-gas kicks turned into uncontrolled blowouts due to the failure of former diverter systems installed several decades ago. Failure is seen as a result of the systems complexity, its lack of functional reliability and its inability to cope with the severe dynamic
30、 loads. Certain drilling supports are exposed to specific threats associated with shallow gas blowouts, e.g. risk of cratering, risk of ship-shaped vessel capsize. Unprepared or inadequately trained drilling crews experience a high level of stress when facing a violent shallow gas flow.In the afterm
31、ath of shallow gas blowouts during the last four decades, comprehensive inquiries and reports have been carried out, in particular by the specialists involved in combating these events, and significant findings and conclusions have been published. In the meantime, the manufacturing industry has deve
32、loped various equipment aimed at significantly improving the safety of shallow-gas drilling operations.This International Standard has been prepared taking these aspects into consideration.

It covers both onshore and offshore drilling operations, and considers also the au
34、xiliary equipment associated with floating rigs.The specified requirements concern the following diverter equipment: annular sealing devices; vent outlets; diverter valves; diverter piping.This International Standard highlights the concerns associated with the selection of a marine floating drilling
35、 support. It covers safety issues concerning key rig equipment, and important steps of action required prior to starting the drilling operations.It provides only general guidelines regarding the response to be given to a shallow-gas flow.2 Normative referencesThe following documents, in whole or in
