The Maharatna CPSE is looking to fill critical positions that require substantial post-qualification experience and specialized expertise. The positions are primarily based at the Field Headquarters in Duliajan, Assam, though selected candidates may be transferred to any OIL operational area or office as per organizational requirements.

The recruitment follows a structured process with clear eligibility criteria and a transparent selection mechanism. As a government undertaking, OIL offers stable employment with competitive compensation packages and the professional satisfaction of contributing to India's energy security. The organization has specified that all educational qualifications must be from universities or institutions recognized by appropriate statutory authorities in India.

Important Dates

The recruitment timeline is clearly defined, with specific cut-off dates that candidates must carefully note. The online application portal opens on 28 May 2026, providing candidates with exactly one month to complete and submit their applications. The window closes at 23:59 hours on 28 June 2026, after which no applications will be accepted.

A critical date to remember is 28 June 2026, which serves as the cut-off date for calculating age, experience, and qualification eligibility. All criteria must be satisfied as of this date. For the personal interview stage, shortlisted candidates will receive individual notifications via email with specific date and time details, as the interview schedule will be communicated directly to qualified applicants.

Vacancy Details

The recruitment notification announces a total of 10 vacancies distributed across six different specialist positions. These include Deputy Chief Chemist, Deputy Chief Geologist, Deputy Chief Engineer (Reservoir), Deputy Chief Geophysicist, Deputy Chief Engineer (S&E), and Economist roles. The vacancies are provisional and subject to actual organizational requirements.

The distribution includes specific reservation categories as per government directives, with one position reserved for Persons with Benchmark Disabilities (PwBD). The majority of positions fall under Grade D, while the Economist position may be filled at Grade D, E, or F levels depending on candidate qualifications and experience. This structured approach ensures opportunities for candidates across different experience levels and backgrounds.

Eligibility

Eligibility criteria for these positions are stringent and specific to each role. All candidates must be Indian nationals with full-time post-qualification work experience in executive cadre roles. The minimum experience requirement is 09 years for most positions, with higher requirements for senior Economist grades. Experience from academic, research, fellowship, consultancy, or part-time roles is explicitly excluded from consideration.

Educational qualifications vary by position but generally require postgraduate degrees with minimum percentage requirements. For example, the Deputy Chief Chemist position requires a PG Degree in Chemistry with minimum 60% marks and background in Physics, Chemistry, and Mathematics at graduation level. Similar specific educational backgrounds are required for other technical positions, ensuring candidates possess the necessary foundational knowledge for their respective roles.

Age Limit

Age limits are position-specific and calculated as of 28 June 2026. Most Grade D positions have an upper age limit of 39 years, while the Economist position has varying limits depending on the grade applied for (39 years for Grade D, 44 years for Grade E, and 49 years for Grade F). The notification incorporates age relaxations for various categories including additional years for candidates holding postgraduate degrees.

Age relaxations follow government norms: 3 years for OBC (Non-Creamy Layer), 5 years for SC/ST categories, and additional benefits for ex-servicemen and other specified categories. However, there is an absolute ceiling of 54 years that cannot be exceeded even after applying all permissible relaxations. Candidates should carefully calculate their age as of the cut-off date considering all applicable relaxations.

Application Mode

The application process is exclusively online through the official OIL recruitment portal. No offline or physical applications will be accepted under any circumstances. Candidates must access the application system through the designated online portal and complete all required fields accurately.

The online application system requires candidates to provide detailed information about their educational qualifications, work experience, personal details, and other relevant information. Since the selection process relies heavily on the information provided in the application, candidates must ensure all details are accurate and verifiable. Any discrepancies between application information and actual documents may lead to disqualification at any stage of the recruitment process.

Selection Process

The selection methodology is straightforward yet rigorous. There is no written examination component - selection is based solely on performance in the personal interview. Shortlisting for interviews will be conducted based on the details provided in the online applications, with only eligible candidates being invited to participate.

If the number of applications is exceptionally high, OIL reserves the right to raise the minimum eligibility standards to manage the interview process effectively. Provisionally selected candidates must subsequently clear a Pre-Employment Medical Examination (PEME) conducted either at OIL Hospital in Duliajan or at government medical facilities. Final appointment is contingent upon both interview performance and medical fitness certification.

Application process reference

The application process requires careful attention to detail and preparation of necessary documents. Candidates should begin by thoroughly reading the official notification to understand all eligibility requirements and position-specific criteria. Gathering all relevant documents including educational certificates, experience certificates, age proof, and category certificates (if applicable) is essential before starting the application.

Access the official application portal through the designated website and complete the registration process to create your applicant profile. Fill all sections of the application form accurately, double-checking all information against your original documents. Upload scanned copies of required documents in the specified formats and sizes.
