Service Unit Operators, Oil and Gas
Service unit operators, oil and gas (O*NET 47-5013.00) operate well service units, pumps and pressure control equipment to maintain oil and gas wells, inspect tools and record operations. U.S. 2025 wages and 2025–2035 employment come from the 47-5013 occupational line; Chinese urban unit averages are industry background only and are not this occupation's precise wage.
Quick decision
Be cautious if you are unwilling to follow wellsite safety procedures, conceal excursions or restart equipment without authorization.
First complete the anomaly handover card for a fictional 8–10 arbitrary unit range and a reading of 12.
Those willing to verify well conditions, equipment and tools and original readings repeatedly and hand over honestly can explore coaching.
The fictional values are not actual well control settings; A5 is paper only and grants no driving, well control or equipment operation authority.
The work operates equipment to improve oil flow from producing wells or to clear obstructions such as stuck pipe tools, including fishing tool tasks; actual work follows training authorization and trainee exercises are narrower.

The local onet and bls alias entries both point to the 47-5013 source tasks and support the task background of equipment checks, pressure control, pumping and clearing, and reporting. The six cards are editorial scenarios and verification suggestions, not incident statistics or well control plans; fictional readings are not field limits, and specific measures must be verified against local equipment training and formal procedures.
Wellsite equipment and crew personnel
Unverified pressure and well condition anomalies may lead to danger or incorrect operations.
Follow worksite procedures to stop the affected process and hand it to the authorized team; do not adjust pressure based on paper.
Fictional A3: reading 12 exceeds 8–10; instrument status to be verified.
Equipment inspection and operating personnel
A gap in pressure control device inspection affects status judgment.
Keep the missing page as to be verified; a report cannot establish that the check was normal.
Fictional A4: device inspection record has a missing page.
Unit drivers and nearby personnel
Vehicle unit and mechanical anomalies may injure people and damage equipment.
Inspect per equipment and vehicle procedures; do not work when conditions are not met.
Fictional: preparing to start work with an unverified abnormal unit noise.
Lifting and crew personnel

Verify per designated equipment procedures and training; do not direct lifting based on an exercise.
Fictional: cable inspection status not verified.
Wellsite operations and nearby personnel
Unknown combustible media or gas conditions affect personnel safety.
Verify per worksite monitoring and operating procedures; hand anomalies to the authorized team.
Fictional: gas monitoring status unknown.
Shift handover, billing, and review personnel
Fictional service completion and resumption conceal open items.
Keep original readings, the missing page, and execution and acceptance status; do not fabricate retest approval.
Fictional: recording the paper 20% deviation as pressure adjusted and resumed.
Precise tasks support risk breakdown, not incident frequency.
Task background of equipment checks, pressure control, clearing, and service reports for 47-5013; does not support incident frequency or complete worksite handling procedures.
Industry distribution is not evidence of worksite safety.
U.S. certificate entry points are not a uniform threshold in China.

12>10, exceeding the fictional upper limit by 2 arbitrary units; 2/10=20% is only the paper reading's relative deviation from the upper limit, not actual well pressure or incident probability. A3 instrument status to be verified and A4 missing inspection page: stop the paper process and hand it to the authorized team; A5 do not adjust pressure or restart, and do not write resumption without retest approval.
A2's 8–10 and A3's 12 are the same arbitrary units; do not convert them into real pressure or adjustment amounts. The cause may relate to the instrument or well condition, but the prompt does not establish it, so you cannot directly say the instrument failed.
Keep A1 instructions, A3 reading with instrument status to be verified, A4 missing page, and A5 authority; real wellsites are handled per authorized team procedures, and no executable well control instruction is given.

Qualification and authorization boundary notes
The paper exercise cannot replace real job training, equipment authorization, and worksite approval.
This round did not adopt a single-employer hiring case; entry information in U.S. official materials and Chinese job requirements are understood separately, and an unverified posting must not be written as a universal occupational threshold.
Well condition, tools and equipment, and service records are used per job authorization; O*NET tasks are not a basis for Chinese privacy law or uniform qualification.
The U.S. industry distribution of service unit operators, oil and gas is an employer scenario signal, not a future growth rate, net gain, or Chinese demand. Specific conditions, authorization, qualifications, and statistical scope must be checked against the target region and original sources.
Hiring sample notes
Insufficient evidence: no Chinese posting with verifiable identity, date, well service duties, pay, and authorization for this occupation was obtained; no uniform threshold is inferred.

Questions and sources
What do service unit operators, oil and gas do?
Operating well service units, pumps and pressure control equipment to maintain oil and gas wells, inspecting tools and recording operations.
How is it different from adjacent occupations?
Task objects, outputs, and qualifications differ; verify against the original text of the formal position.
What is U.S. entry preparation like?
U.S. 47-5013 typically requires no formal educational credential, less than five years of related experience, and medium-term on-the-job training; O*NET JobZone1–2. Chinese well control equipment qualifications are verified separately.
Is there precise comparable wage data for China?
Insufficient evidence: no exact national wage for this occupation in China was obtained. NBS2025 mining non-private/private pre-tax annual averages of 143,361/79,169 yuan cover multiple occupations and serve only as a broad reference.
What is the U.S. median annual wage?
The O*NET 2025 47-5013 median is $58,160, P10 $38,940, and P90 $97,560; these do not represent an individual offer.
How should the U.S. employment projection be read?
BLS 47-5013 employment is 43.8 thousand in 2025 and 44.3 thousand in 2035, a change of +1.1%; average annual openings 3.8 thousand.
Can AI replace key judgment?
No. AI can organize drafts; operating equipment under authorization and monitoring pressure and mechanical anomalies require human verification.
How do you demonstrate entry-level ability?
Use the fictional A1–A5 to produce the task input, formula or criteria, anomaly, and handover cards.
How is the fictional exercise judged?
12>10, exceeding the fictional upper limit by 2 arbitrary units; 2/10=20% is only the paper reading's relative deviation from the upper limit, not actual well pressure or incident probability. A3 instrument status to be verified and A4 missing inspection page: stop the paper process and hand it to the authorized team; A5 do not adjust pressure or restart, and do not write resumption without retest approval.
Which adjacent occupations can you move into?
You can compare oil and gas derrick operators, oil and gas rotary drill operators, oil and gas wellsite helpers, and extraction helpers; changing roles still requires adding specialized skills.
Keep O*NET 47-5013.00 precise tasks, BLS 47-5013 U.S. statistics, and the fictional exercise separate; core judgment is the responsibility of authorized persons.
Occupational identity and tasks are based on O*NET 47-5013.00; U.S. wages and projections are based on BLS 47-5013; Chinese wages are only NBS urban unit background.
On 2026-10-02, this occupation's 19 tasks, four adjacent definitions, U.S. 2025 wages and 2025–2035 projections, and the NBS mining broad industry and production job group were verified; shared AI methods were reused from the same batch, and other historical links are not described as new visits.
The Chinese explanation of U.S. classification does not establish China-U.S. mutual recognition of qualifications; real work follows local and employer requirements.
