ONGC Geologists and Engineers E1 Exam Pattern 2026

The ONGC E1 Computer-Based Test consists of 85 objective-type questions carrying 85 marks. The examination includes questions from the concerned technical domain along with aptitude, general awareness and English language.

The duration of the examination is 120 minutes. The concerned-domain section differs according to the discipline selected by the candidate. For example, Mechanical Engineering candidates will face questions from Mechanical Engineering, whereas candidates applying for Geology will receive questions related to the prescribed Geology syllabus.

There is no negative marking in the CBT according to the available recruitment details. Candidates should still focus on accuracy and effective time management because the CBT score plays a significant role in the overall selection process.

Subjects Covered in ONGC E1 Question Paper 2026

Petroleum Engineering

Petroleum Engineering candidates should revise major topics such as reservoir engineering, drilling technology, production engineering, petroleum geology, well logging, formation evaluation and petroleum fluid properties. Candidates should practise both conceptual questions and numerical problems because technical questions can test theoretical understanding as well as practical application.

Mechanical Engineering

Mechanical Engineering candidates should focus on thermodynamics, fluid mechanics, strength of materials, theory of machines, engineering mechanics, heat transfer, manufacturing processes, machine design and other core engineering subjects. Formula revision followed by numerical practice can improve performance in the technical section.

Chemical Engineering

The major areas for Chemical Engineering include chemical engineering thermodynamics, fluid mechanics, heat transfer, mass transfer, chemical reaction engineering, process calculations, process control and other fundamental subjects. Candidates should revise important equations and practise numerical problems regularly.

Instrumentation Engineering

Instrumentation candidates should revise measurements and instrumentation, sensors and transducers, control systems, industrial instrumentation, electronics, process control and related engineering fundamentals. Particular attention should be given to basic concepts and commonly used formulas.

Geology

Geology candidates should focus on petroleum geology, structural geology, sedimentology, stratigraphy, mineralogy, geophysics, basin analysis and other areas relevant to the recruitment syllabus. Revision of fundamental geological concepts can help candidates solve conceptual questions more efficiently.
