Well Control & HPHT Training In Deepwater Drilling Operations
WELL CONTROL & HPHT TRAINING IN DEEPWATER DRILLING OPERATIONS
|In August 2015, Vietgazprom commenced its drilling campaigns of 2 deepwater wells VGP-131-TB-1X and VGP-130-TB-1X offshore Vietnam with the sea depth exceeding 1,600 meters at the drilling sites.
The complexity of deepwater wells and the associated risks/costs are much higher than shallow water wells, making this scenario within the drilling discipline one of the most cost sensitive. In deepwater drilling around the world, well control and pressure-related problems account for significant risks. On the other hand, there are limited number of deepwater drilling blowout control options. These challenges can result in failures, greater risk, and expenses for Oil operators & contractors anywhere. On the bright side, these challenges can be overcome by precise, real-time well control that prevents and mitigates problems before they transform to a serious well control event.
In facts, two years after the blowout of the BP deepwater oil well drilled by the Deepwater Horizon rig in the Gulf of Mexico, blowout incident awareness is higher than ever and well control management has demanded global oil & gas players to act on the lessons learned from that experience to ensure that deep-water drilling and production is safe and environmentally compatible. The other top concern in drilling a deepwater well is high temperature and high pressure (HPHT). A HPHT well requires in-depth planning and special attention is needed in order to mitigate the increased risks and uncertainties for HPHT operations. Complacency in the early planning stages of a HPHT well can have severe implications which has a direct impact on cost and safty management.
|Moreover, large-scale well control projects usually involve a large number of personnel performing a wide variety of tasks. Also, if taking into consideration fluctuating oil prices, to keep a deepwater project profitatbe, each operator needs an experienced team in deepwater operations and drilling technologies to provide fit for propose engineering solutions associated with cost efficiency. Therefore, enhancing deepwater well control qualifications & HTHP knowledge for rig personnel is very essential.
PVD Training is proud to be the only local training provider to offer IWCF (International Well Control Forum) accredited Drilling Well Control training and international-recognized HPHT training from basic to advance.
Safety involves the acts of everyone on the rig. So literally all rig personnel is recommended to have knowledge of Well Control & HPHT especially while working with deepwater /HPHT wells.
|However, specific positions on the rig are required to obtain Well Control training as a MUST. According to the new regulation per OGP (International Association of Oil & Gas Producers) Report No.476 as attached, apart from conventional drilling personnel (Assistant Driller, Driller, Tool Pusher, OIM, Rig Manager), additional rig crews (Floorman, Derrickman, Barge Engineer…etc) MUST also hold valid Well Control certification at Basic Level (Level 2) effective from August 2014.||Those who are working on the rig and with the rig on a daily basis (Drilling Superintendents/Engineers, Rig Man-agers, Drilling Managers, Toolpushers, Drillers, Assistant Drillers, Rig Crew, Rig Service Personnel, Geoscience Personnel, etc.) are recommended to take HPHT training to obtained a much improved understanding of the chal-lenges which will be faced and the mitigations required to minimize the probability of failure/mishap.|
|With reference to that statement, the following personnel must ensure to hold a current IWCF well control certificate:
|There will always be potential oil well control problems, as long as there are drilling operations out there in the world, especially with the increasing complexity of well: deepwater and HPHT adding to the risks. Most of these well control problems occur as a result of some minor errors and can be eliminated, even though some are actually unavoidable, unfortunately. Since we know the consequences of failed well control are severe, efforts should be made to prevent some human errors which are the root causes of these incidents. One of the causes is the lack of knowledge and skills of rig personnel and lack of understanding of oil well control training.
In summary, proper and sophisticated well control & HPHT training involves developing competent personnel that are able to recognize well control problems and know what to do to mitigate against them from the minor events.
