Prevention of Explosions During Drilling and Completion
Operations
Over the past several years, there have
been a number of serious oilfield fires and explosions that have resulted in
worker injuries and fatalities. During this same time, there has been an
increase in the use of air during drilling, completions, and workover
activities in Western Canada. While regulations exist with respect to explosive
hazards, there are no clear industry guidelines dealing with air-hydrocarbon
mixtures in these wellsite operations.
To address the concerns of both industry and
regulators, efforts are underway to prepare an Industry Recommended Practice –
IRP 18: Explosive Atmospheres in Wellbores, Vessels,
Tanks, and Piping Systems. The IRP is being developed under the direction
of the Drilling and Completions Committee (DACC), a joint industry/government
committee established to develop safe, efficient and environmentally suitable
operating practices for the Canadian Oil & Gas industry in the areas of
drilling, completing, and servicing of wells. It is important to highlight
that, although the efforts are focused on drilling and completion operations,
the research is also expected to have an impact on other oil and gas operations
where the potential for explosions resulting from air-hydrocarbon mixtures
exist.
Because of the complex
nature of this issue, the work to develop this IRP is being jointly sponsored
and chaired by the Canadian Association of Petroleum Producers (CAPP) and the
Petroleum Services Association of Canada (PSAC). The IRP is being developed in
partnership with the University of Calgary. The UofC brings extensive
experience to this initiative as a result of their previous investigative
research related to industry incidents. The Committee expects to publish the
IRP in 2004 in cooperation with the Canadian Petroleum Safety Council (PSC).
To ensure this task is successfully
accomplished, the development committee for IRP #18 is petitioning industry and regulators for reference
information including incident case histories, procedure documents, and
experience related to fires and explosions. Two key areas of interest are: 1)
Incidents, including close calls, where air was used for either operations or
the purging of equipment, and 2) The procedures and controls that companies
have implemented to maintain safe operations. The intent is to better
understand both the conditions where the use of air is safe, and where it
presents a hazard.
