Yesterday, the Chemical Safety Board published their final report on an oilwell
blowout incident that occurred in Burleson County, Texas, on January 29th,
2020. The flash fire that occurred as a result of that blowout killed three
workers and injured another. The report identified four key safety issues that
contributed to the severity of the incident and made four recommendations that
would help prevent the reoccurrence of this type of incident.
The four identified safety issues were:
• Well planning,
• Well control for completed wells
in underpressured reservoirs,
• Ignition source management, and
• Federal safety regulatory
requirements
Recommendations
The CSB included four recommendations in this report:
• 2020-04-I-TX-1 - Chesapeake
Operating, LLC - Develop or revise policies incorporating the recommendations
of API RP 59 regarding well planning, specifically the inclusion of well
history review in conjunction with workover well control planning,
• 2020-04-I-TX-2 - American
Petroleum Institute (API) - Publish specified information in an appropriate
document such as API RP 59 Recommended Practice for Well Control Operations,
• 2020-04-I-TX-3 - Occupational
Safety and Health Administration (OSHA) – Remove the exemption for oil and gas
drilling and well servicing from the Control of Hazardous Energy standard (29
CFR 1910.147) and expand its applicability to cover oil and gas production and
workover operations, and
• 2020-04-I-TX-4 - Occupational
Safety and Health Administration (OSHA) - Promulgate a new standard with
prescriptive requirements, similar to the Control of Hazardous Energy Standard,
as well as a performance-based safety management system framework, similar to
the OSHA Process Safety Management (PSM) Standard, that applies to the
drilling, production, and servicing/workover activities surrounding onshore oil
and gas wells.
As a result of this investigation, the CSB is closing
2018-01-I-OK-1 as it is now being superseded by 2020-04-I-TX-3. This now leaves
the CSB with 177 open recommendations.
Commentary
With the publication of this report, the CSB has cleared
their backlog of investigations. This has been a long road and it has
impeded the ability of the Board to initiate new investigations. There is only
one active
investigation on the books (BP - Husky Oregon Chemical Release
and Fire). It dates back to 2022, so this investigation
should be close to done (we hope). It will be interesting to see how aggressive
the CSB is in initiating new investigations.
