At a glance

A petroleum technician operates, monitors and maintains equipment at oil and gas fields, pipelines and refineries, usually after Class 12 science or ITI.

A petroleum technician works hands-on with the equipment used to extract, transport, refine and test oil and gas, and supports the engineers who plan the work. It is a skilled technical role that sits below engineer level and is usually entered through a diploma, an ITI trade or an industrial apprenticeship.

For students who do not want a four-year engineering degree, this career offers a practical route into the energy sector. Public-sector companies such as Indian Oil Corporation (IOCL), ONGC and Oil India have advertised technician and trade apprentice posts in 2025 and 2026, so the openings are real, though each notification has its own eligibility and closing date.

The work is shift-based and can be physically demanding, and it involves strict safety rules at every step. Students who enjoy machines, careful record-keeping and working as part of a team tend to do well in it. Check each recruitment notice for current eligibility, pay and dates before you apply.

What Does a Petroleum Technician Do?

Day-to-Day Responsibilities

  • Operate and monitor pumps, compressors, valves and process units in refineries, plants or well sites as per the operating procedure.

  • Carry out routine rounds, log readings and report abnormal pressure, temperature or flow to the shift in-charge.

  • Help with preventive and breakdown maintenance of pipelines, tanks, pumps and instruments.

  • Take samples of crude oil, products or gas and run basic laboratory tests to check quality.

  • Follow work permits, gas testing and lock-out procedures, and take part in firefighting and safety drills.

  • Assist engineers during plant shutdowns, turnarounds and the installation of new equipment.

  • Keep accurate records and logbooks, and follow environmental and emission rules.

Where They Work

Most openings are with large public-sector companies. Recent recruitment notices have come from Indian Oil Corporation (IOCL), ONGC, Oil India Limited and Chennai Petroleum Corporation (CPCL), covering refineries, oilfields and pipeline operations. Many of these are technician or trade apprentice posts.

Technicians also work for private refineries, petrochemical plants, oilfield service companies and contractors who maintain plants for the larger operators. Work is usually at remote oilfields, refinery complexes, pipeline stations and storage terminals, so candidates should be ready to relocate and work on rotating shifts.

How to Become a Petroleum Technician in India?

After Class 10

Some trade and apprentice notices, including IOCL's, have accepted a Class 10 pass. Strengthen maths and science, and look at ITI or polytechnic options. Check each notification for the exact requirement.

After Class 12

Take the science stream with physics, chemistry and maths or biology. You can then join a three-year diploma in petroleum, chemical or mechanical technology at a polytechnic, which is the usual route for technician posts.

ITI or Trade Certificate

An ITI trade such as fitter, electrician or instrument mechanic is a practical alternative. It suits students who want to start work sooner and build hands-on skills on plant equipment.

Apprenticeship

Apply to technician and trade apprentice notices from public-sector oil companies. These are training positions under the Apprentices Act and are a common entry point, but they do not by themselves guarantee a permanent job.

Licence / Certification

Short safety certificates in fire safety, gas testing and work permit systems help you stand out. Some employers require specific certifications, so confirm this in the job posting.

First Job

Start as a junior technician, trade apprentice or operator. With experience and further training, you can move towards shift in-charge or senior technical roles.

Scope and Future of Petroleum Technician in India

Demand for petroleum technicians is tied to the upkeep of refineries, oilfields and pipelines. Recruitment notices from IOCL, ONGC, Oil India and CPCL in 2025 and 2026 show that these companies continue to take in technician and trade apprentice staff, although the number of posts changes from one notification to the next.

Growth is most likely in refinery upgrades, petrochemical projects and the handling of cleaner fuels and biofuels, all of which need trained operators and maintenance staff. Technicians who add instrumentation, automation or safety skills are often better placed for these roles.

Overseas work is possible in oil-producing countries that hire technicians for their plants and fields. Such roles usually need several years of experience and sometimes an internationally recognised certification. Students can build this profile by starting with a diploma or ITI and steadily adding experience.

Petroleum Technician: Frequently Asked Questions

Can I become a petroleum technician after Class 12 without an engineering degree?

Yes. A diploma in petroleum, chemical or mechanical technology, usually a three-year polytechnic course after Class 10, is a common route for technician roles. Some technician posts also accept a relevant ITI trade certificate. Check the eligibility in each recruitment notice, because requirements differ between employers and between posts.

Is an ITI enough to become a petroleum technician?

An ITI can be enough for some trade and apprentice posts, especially in fitter, electrician or instrument mechanic trades. Some higher technician roles prefer a diploma. An ITI can also be a good starting point, because you can later add a diploma or gain experience and move up within the industry.

What is the salary of a petroleum technician in India?

Salary depends on the employer, the post and your experience. Public-sector recruitment notices state the pay for each post, so the most reliable figure is the one in the official notification you are applying for. Pay at senior levels is usually higher and depends on the shift and responsibility involved.

Do I need a petroleum engineering degree to work in oilfields?

No. Many oilfield and refinery jobs for technicians need a diploma, an ITI certificate or an apprenticeship rather than a degree. Engineers usually plan the work and make design decisions, while technicians operate, monitor and maintain the equipment. Some technicians later take further study to move into engineering roles.

Are petroleum technician apprenticeships permanent jobs?

An apprenticeship is a training position and does not by itself guarantee permanent employment. It gives you structured training and experience in a real plant or field. Read the notification carefully to understand the training period, stipend and what happens after training ends.

Is the work of a petroleum technician dangerous?

The work involves hazards such as flammable gases, high pressure and heavy machinery, so safety is strict. Companies use work permits, gas testing, protective equipment and regular drills. Technicians who follow procedures and complete safety training manage these risks well.

What is the difference between a petroleum technician and a petroleum engineer?

A petroleum engineer usually holds a degree and designs, plans or manages oil and gas projects. A petroleum technician holds a diploma, ITI or apprenticeship training and runs, monitors and maintains the equipment on the ground. Both roles work closely together in refineries and oilfields.
