Law, standards and certification for drilling and servicing

HSE-330, Lesson 2, mapped the two kinds of regulator that touch every oil and gas site: the worker safety regulator, which protects employees, and the energy regulator, which oversees wells, facilities and pipelines and protects the public and the environment. On a drilling or service rig both are very visible. The worker safety rules govern fall protection on the mast, guarding on the drawworks and the training of the crew. The energy regulator's rules govern how the well is designed, how blowout preventers are tested and who must hold well control certificates. Industry standards and recommended practices fill in much of the detail. This lesson maps those layers for rigs, then looks at the certifications a rig worker can expect to need.

Laws, directives and standards change. The dates and editions below were checked in October 2026, but before relying on a specific requirement always check the current version from the regulator or standards body. This course names documents so that you know where to look; it does not reproduce their clauses.

Worker safety law on the rig

In the United States, OSHA's general industry standards (29 CFR 1910) apply to drilling and servicing rigs, together with the general duty clause of the OSH Act, which requires employers to protect workers from recognized serious hazards. OSHA has no standard written specifically for oil and gas well drilling; a proposed drilling standard from the 1980s was never finalized. Some general industry standards expressly exclude oil and gas well drilling and servicing from their scope, including the lockout/tagout standard (1910.147) and the process safety management standard (1910.119). Others apply in full, such as walking-working surfaces and fall protection, hazard communication, respiratory protection, noise and the respirable crystalline silica standard (1910.1053). OSHA enforces through inspections and citations, often using the general duty clause together with industry recommended practices such as API RP 54 as evidence of recognized hazards and feasible controls. States with their own approved OSHA plans, such as New Mexico and Wyoming, enforce equivalent rules. North Dakota is a federal OSHA state.

Energy regulators and well requirements

In the United States, wells on private and state land are regulated by state oil and gas agencies. In North Dakota the Industrial Commission's Oil and Gas Division issues permits and sets drilling, casing, cementing, blowout prevention and plugging requirements; in Texas the Railroad Commission plays the same role, including Statewide Rule 36 for hydrogen sulfide operations. On federal and tribal onshore leases, the Bureau of Land Management sets drilling requirements in its regulations at 43 CFR 3172, which replaced the former Onshore Order 2, including blowout preventer and testing requirements. Offshore, the Bureau of Safety and Environmental Enforcement regulates drilling under 30 CFR 250, including the well control rule first issued in 2016 and later revised, and requires a safety and environmental management system (SEMS) based on API RP 75.

Energy regulators focus on the well and the public, but their rules protect rig workers too. A properly designed casing program, a correctly rated and tested BOP stack and a trained crew that practices kick drills are exactly what keep a kick from becoming a blowout that kills the people on the floor. Conversely, worker safety regulators increasingly look at process safety and well control when they investigate rig incidents.

Industry standards and recommended practices

The American Petroleum Institute (API) publishes the standards and recommended practices most widely used on US rigs. API RP 54 covers occupational safety and health for oil and gas well drilling and servicing operations. API Standard 53 sets requirements for well control equipment systems, including blowout preventers, accumulators and testing. API RP 59 covers well control operations, API RP 49 covers drilling and well servicing operations involving hydrogen sulfide, and API RP 75 covers safety and environmental management for offshore operations. The International Association of Drilling Contractors (IADC) publishes its own guidelines, including the HSE case guidelines for drilling contractors and a large library of safety alerts that share lessons from incidents.

Recommended practices are not law in themselves, but they carry weight in three ways. Regulators may require them by reference. Contracts between operators and contractors often require them. And when an incident is investigated, inspectors and courts look at recognized industry practice to decide whether a hazard was known and whether a feasible control existed. A rig that ignores a widely used recommended practice will find it hard to show it took every reasonable precaution.

Certifications on a rig

Rig workers collect certificates. Some are required by law or regulation, some by the operator's contract and some by the drilling contractor's own program. The common ones fall into four groups.

Certificates expire, usually after one to three years depending on the course, and a lapsed well control or H2S certificate can stop a worker from going to the floor. Rig managers track certificates for their crews, and many operators audit contractor training records before a rig starts work. A certificate shows that a person completed training at one point in time; it does not guarantee competence today. That is why rigs combine certificates with mentoring, drills and supervisors who watch how people actually work.

The program below checks invented certificate records for part of the Rig 31 crew against an invented spud date and lists anything that has expired or will expire during the planned 40-day program on the pad.

from datetime import date, timedelta

spud = date(2027, 2, 1)                 # invented start of drilling
end = spud + timedelta(days=40)         # planned program length
records = [
    ("Driller A",      "Well control (driller level)", date(2027, 6, 30)),
    ("Driller B",      "Well control (driller level)", date(2027, 2, 20)),
    ("Rig manager",    "Well control (supervisor)",    date(2028, 1, 15)),
    ("Derrickhand A",  "H2S",                          date(2027, 1, 10)),
    ("Floorhand C",    "First aid and CPR",            date(2027, 3, 5)),
    ("Motorhand B",    "H2S",                          date(2027, 9, 1)),
]
for who, cert, expiry in records:
    if expiry < spud:
        status = "EXPIRED before spud"
    elif expiry <= end:
        status = f"expires day {(expiry - spud).days} of program"
    else:
        status = "valid for program"
    print(f"{who:14} {cert:30} {expiry}  {status}")

Driller A      Well control (driller level)   2027-06-30  valid for program
Driller B      Well control (driller level)   2027-02-20  expires day 19 of program
Rig manager    Well control (supervisor)      2028-01-15  valid for program
Derrickhand A  H2S                            2027-01-10  EXPIRED before spud
Floorhand C    First aid and CPR              2027-03-05  expires day 32 of program
Motorhand B    H2S                            2027-09-01  valid for program

Three records need action before or during the program. Derrickhand A cannot work on the lease until the H2S certificate is renewed, and the renewals for Driller B and Floorhand C should be booked now so that neither has to leave the rig partway through. Simple checks like this are easy to automate and save rigs from discovering a lapsed certificate during an operator audit or, worse, after an incident.

Who holds which duty

Law places duties on several parties at once, and on a rig they overlap. The drilling contractor, as employer, must protect its workers, train them, supervise them and maintain its equipment. The operator, as licensee and usually the party in control of the site, has duties for the well design, the overall site, coordination of employers and, in many jurisdictions, as prime contractor or as a controlling employer. Service companies have the same employer duties to their own workers. Supervisors have personal duties to ensure that workers under them follow safe practices. And every worker has a duty to follow the rules, use the protective equipment provided, report hazards and refuse or stop unsafe work. Lesson 12 returns to how these duties are written down in bridging documents.

Inspections, incidents and reporting

Both kinds of regulator inspect rigs. A worker safety officer may arrive unannounced, walk the lease, check fall protection on the mast, guarding, housekeeping and training records, interview workers and issue orders or citations. An energy regulator inspector is more likely to check the BOP stack and accumulator, test records, kick drill logs, the flare system, the sour gas emergency plan and the casing and cementing program. Inspectors from both often look at the same documents, such as the hazard assessment and the orientation records, for different reasons. Crews should treat an inspection as a free second set of eyes rather than an interruption.

Serious incidents must be reported quickly. Under OSHA's recordkeeping rules, an employer must report a work-related fatality within 8 hours and an in-patient hospitalization, amputation or loss of an eye within 24 hours. State oil and gas agencies, BLM and BSEE have their own requirements for reporting blowouts, fires, spills and other well incidents, and some states require immediate notice of hydrogen sulfide releases. The rig's emergency response plan should list who calls which agency and when, and the scene should be preserved, except to protect people or prevent further harm, until investigators allow work to resume.

Industry sharing adds a further layer. Safety alerts from IADC, Energy Safety Canada and individual companies describe what went wrong in incidents and near misses so that other crews can learn without repeating them. Many of the hazards in the following lessons, such as mismatched hammer unions and dropped objects from the mast, are known largely because crews reported near misses and companies shared the lessons. Reading the latest alerts at the pre-tour meeting is a simple, cheap habit that keeps those lessons alive.
