Service Unit Operators, Oil and Gas

43,140 US workers · median $58,160/yr · Construction

EXPOSED

Rigging up workover units, running tubing and rods, pumping acid or cement jobs, and reading pressure behavior at the wellhead are hands-on tasks in mud, wind, and H2S — language models do essentially none of it. The real automation pressure is mechanical and remote-operations driven: automated pipe handling, hydraulic catwalks, and centralized frac/pump control rooms cut crew headcount per job rather than eliminating the role. Certification (well control, H2S, CDL) is employer- and operator-mandated rather than a personal professional license, so the regulatory shield is thinner than an electrician's.

10-year outlook: The work stays physical and on-site through the 2030s, but crews per unit keep shrinking as pipe handling and pump control automate — and headcount will swing on oil prices far more than on AI.

US employment, 2019–2025-16.7%
51,76043,140 workers

Nearly all of this fall was the 2020 shock. It has been climbing back since.

Median pay $46,740 → $58,160 -0.5% in real terms (nominal +24.4%, less ~25% US inflation over the period)

The job count is not the verdict

This line is counted by the Bureau of Labor Statistics — the one figure on this page that isn't a judgement of ours. Headcount moves on demand, offshoring, demographics and the business cycle, and automation is one term among several, often not the loudest.

So a falling line is not evidence that AI did it, and a rising one is not evidence that it won't. Both happen in this register: some occupations resist automation and shrink anyway, others are highly automatable and keep growing. The marked year is 2020.

BLS projection, 2024–2034

+0.4% 45,200 → 45,400 on the projections basis

Growing, and only partly exposed

The BLS expects +0.4% more of these jobs by 2034, and at 61/100 the work is only partly exposed — some tasks are automatable, the core of the job is not. Nothing here is in tension.

Different clocks. The score is what current AI could do to this work today. The projection is how many of these jobs will exist in 2034. Everything between the two — how fast employers actually adopt, whether demand grows in the meantime — is why they can point opposite ways without either being wrong.

~4,100 openings a year on average, including replacing people who leave.

Score — 61/100 resistance

Holding it up: embodiment (19/20). Weakest point: trust premium (7/20).

Five dimensions, 0–20 each, summed. Higher means more protected. The arithmetic is shown so you can check it: 16 + 19 + 7 + 7 + 12 = 61. · Scored 2026-08-11, and re-examined when evidence accumulates rather than on a schedule.

Task resistance 16/20

Tasks largely resist digitisation Latching elevators on a stand of tubing, breaking out a stuck rod string, spotting a swab cup down 6,000 feet by feel on the sandline — these are muscle-and-torque tasks on a specific wellbore with no two rig-ups alike, which is why 16 rather than a mid-teens hedge: the only digitisable slice is the pump-rate schedule and the job ticket.

Embodiment 19/20

Hands-on in uncontrolled environments You work off a derrick floor or a truck deck at 3 a.m. in freezing wind, in live-well pressure, near H2S, wrestling 500-lb BOP stacks and hot iron on lease roads that wash out — 19 not 20 only because some pump and blender operation is now run from a data van instead of standing at the manifold.

Liability shield 7/20

Certification preferred, not legally required IWCF/WellSharp well control, H2S Alive, and a CDL with tanker endorsement all gate who gets on the truck, but they are operator- and employer-mandated tickets that revoke with your badge — no state board holds your personal number when a job goes bad, so the consultant or engineer of record eats the exposure and you land at 7 rather than 12.

Trust premium 7/20

Some relationship component Operators and pumpers request specific crews and specific operators by name because they trust their hands on a workover, and repeat lease work runs on that reputation, but the contract is awarded to the service company on price and equipment availability, which caps the personal relationship at 7.

Judgment & accountability 12/20

Meaningful discretion You decide when to shut in on a rising annulus pressure, when to stop pulling and back off, and whether that squeeze took — real calls made in seconds with the well live — but they run inside a written program from the operator's engineer and a company man on site with final say, putting you at 12 and not 16.

Where this experience transfers — occupations you could move toward

Computed from U.S. Dept. of Labor O*NET skill and knowledge profiles: high overlap with what you already do, a materially higher resistance score, no large jump in required training, and no licence you would have to start a new pipeline to get. Targets that pay meaningfully less, that are themselves COOKED, or whose own headcount is falling are excluded — a move into a shrinking trade is not an escape.

What would move this back up — beyond any one person

The moves above are yours to make. This is the other half: what would have to change in the world for the occupation itself to score higher. None of it is in any one person's gift, but it is where the floor actually comes from. Scores here are not a one-way ratchet. Only two of the five dimensions — task resistance and embodiment — track what machines can do. The other three track law, what buyers will pay for, and who is answerable, and those move in both directions, often in response to the same pressure AI creates. If every lever below landed, this occupation would score around 75/100 — SAFE.

4 specific changes that would raise this score
  • already happening judgment accountability +4

    As remote pump-control rooms take the routine rate/pressure work, the on-site remaining tier becomes barrier integrity calls, kick recognition, and shut-in decisions under ambiguity. If company policy formally designates the wellhead operator as the person with stop-work and shut-in authority (as some majors' stop-work-authority programs already do in writing), the accountability score rises without any new law.

  • already happening task resistance +2

    Task-mix shift: automated pipe handling and hydraulic catwalks strip the repetitive tripping and rig-up labor, leaving diagnosis of stuck pipe, unexpected pressure behavior, H2S response, and improvised repair in bad weather — the tier machines handle worst. Already visible in reduced crew size per unit rather than unit elimination.

  • plausible liability shield +5

    A state or federal rule making well-control/pressure-pumping operations require a named, individually certified operator of record who personally signs the job ticket — analogous to BSEE's Well Control Rule requirements for offshore or Texas RRC operator certification for cementing/plug-and-abandon jobs. If IADC WellSharp or an equivalent moved from employer-verified to a personally-held, revocable state license with individual sanction authority, the shield thickens materially.

  • plausible liability shield +3

    Insurer-driven requirement (well control underwriters, e.g. after a blowout loss) that a certified individual on-site attest to barrier verification before pumping begins, with that attestation named in the policy — already partially present in operator contractor-qualification programs.

The limit. Trust premium has no plausible route: the buyer is an E&P operator purchasing cost-per-job, and no customer pays a premium for a human service unit hand. Embodiment is already near ceiling at 19. Realistic ceiling is roughly 72-75, and the displacement pressure here is mechanical headcount-per-job reduction, which none of these levers offset.

These are conditions, not forecasts — what would have to happen, not what will. Specific rules, cases and bills are named so you can go and check whether they exist and where they stand; verify before relying on any of them. Nothing here is legal or financial advice.

Who is actually doing this — nobody, on the record

We have no reported case of a named organisation automating this occupation. Not one deployment, not one announcement.

That is worth saying out loud next to a score of 61. The verdict above is about what the work exposes — what current AI could do to these tasks. It is not a claim that anyone has done it. For this occupation those two things have come apart completely: the capability argument is on this page, and the evidence column is empty.

Read that as a gap in the reporting we can see, not proof of absence — the dispatch runs on English-language feeds and misses plenty. If you know of a case, tell us, or add a field report from inside the job.
