This internship focuses on process and operations data analytics using real-time and historical plant data from Distributed Control Systems (DCS) and PI data historians. The intern will support process performance monitoring, anomaly detection, and optimisation initiatives by applying time-series analysis to operational datasets, contributing to data-driven decision-making in upstream operations.
Key Responsibilities
1. Extract, clean, and analyse time-series process data from PI System and DCS sources
2. Support development of process performance dashboards using historical and real-time data
3. Perform basic trend analysis, correlation analysis, and pattern recognition on process variables
4. Assist in identifying process deviations, abnormal operating conditions, and data quality issues
5. Support engineering teams in analysing process stability, equipment behaviour, and operational variability
6. Document data sources, tag structures, assumptions, and analytical methods
Technical Learning Exposure
1. Hands-on experience with PI historian data and DCS tag-based datasets
2. Understanding of time-series characteristics (sampling rate, noise, missing data, lag, drift)
3. Exposure to process control variables and operational KPIs
4. Introduction to analytics supporting process optimisation, reliability, and remote operations
Technical Requirements:
1. Undergraduate student in Chemical Engineering, Electrical/Instrumentation Engineering, Data Science, Computer Science, or related fields
2. Basic understanding of process data, instrumentation, or control systems
3. Familiarity with time-series data concepts
4. Experience or exposure to Python, Excel, Power BI, or similar analytics tools
5. Ability to interpret trends and relate data behaviour to process conditions
Expected Deliverables:
1. Process data dashboards or trend analysis reports
2. Documented findings on process behaviour or anomalies
3. Simple analytical models or scripts for data exploration
Petroliam Nasional Berhad (PETRONAS) is a leading global energy company committed to powering society’s progress in a responsible and sustainable manner. With close to 50,000 employees and a global reach spanning over 100 countries, we are ranked among the world’s largest corporations by revenue in the Fortune Media IP Ltd’s 2022 Fortune Global 500® list.
As Malaysia’s national oil and gas company, we safeguard and manage the nation’s hydrocarbon resources to ensure national energy security and maximise value. We explore, develop and produce hydrocarbons as well as cleaner energy solutions. We have three core businesses, namely Upstream, Gas and Downstream, supported by Project Delivery and Technology division, which acts as an enabler. We recently launched Gentari, our new entity providing customers with cleaner energy and lower carbon solutions in three core offerings – renewables, hydrogen and green mobility alongside our core portfolio.
We remain committed to produce oil and gas in a differentiated manner, with focus on reducing carbon emissions and at competitive cost. Our hydrocarbon portfolio today is two-thirds gas, which puts us in an advantageous position as gas and Liquefied Natural Gas (LNG) will continue to play a vital role even as the energy system evolves. As one of the leading LNG players in the world, PETRONAS will continue to serve the global LNG demand.
As a responsible and conscientious global energy player, sustainability is at the heart of our business and how we operate. Our commitment to responsible business growth and positive contributions to society and the environment remains unwavering. Fuelled by our passion to be a partner for our customers in the journey towards a lower carbon energy future, every step we take brings us closer towards achieving our aspiration of Net Zero Carbon Emissions by 2050 (NZCE 2050).
