Building Today’s and Tomorrow's Energy
Hydrocarbons are more than just oil and gas; they are strategic national assets that fuel economies, ensure energy security, drive industrialisation, and guide nations through the global energy transition. As India rapidly evolves into an energy-intensive economy, a robust, integrated hydrocarbons ecosystem becomes crucial. MEIL Group’s Hydrocarbon Business Unit is uniquely positioned to serve this need by providing comprehensive, end-to-end solutions across the upstream, midstream, and downstream value chain, making it India’s only private player with such a fully integrated presence.
In upstream, through our global subsidiaries Drillmec and Petreven, we provide world-class capabilities in designing, manufacturing, supplying, and operating advanced onshore and offshore drilling rigs. We are supplying 52 indigenously developed drilling rigs for leading national operators such as ONGC and Oil India. The midstream segment is centred on building critical pipeline corridors, refinery units, and petrochemical infrastructure, while the downstream portfolio delivers reliable energy access via city gas distribution networks through transport and distribution systems for households and industries. We will be building India’s first private sector strategic petroleum reserve, a 2.5 million metric tonne underground storage at Padur, Karnataka, for Indian Strategic Petroleum Reserves Ltd (ISPRL).
Leveraging deep technical expertise and a strong project execution track record, our business unit delivers complex, end-to-end Engineering, Procurement, and Construction (EPC) projects. Our responsibilities cover vital infrastructure such as extensive pipeline systems, Greenfield refineries, and specialised process units that are central to the hydrocarbons value chain.
Among the many projects, two ongoing record-breaking initiatives include India’s second-largest Polypropylene Unit (980 KTPA capacity), along with a 59 KTPA Butene-1 Unit, associated conveying systems, advanced bagging facilities; and the world’s largest single-train LLDPE/HDPE plant, capable of producing both linear low-density and high-density polyethylene resins for packaging, automotive, and consumer applications at the Rajasthan Refinery project.
Completed International and Domestic Projects
Over the years, this expertise has led to significant milestones, reflecting both global reach and domestic strength. Our first major international breakthrough was the construction of a 54 MW gas-based power plant for the Arab Potash Company in Jordan, establishing MEIL Group’s credentials in the global hydrocarbons market. In Kuwait, for the Al Zour Refinery, we constructed 66 storage tanks ranging from 20 metres to 78 metres in diameter.
Domestically, we have strengthened energy supply through projects such as the 425-kilometre Geleki Pipeline in Assam for ONGC, connecting multiple oil and gas wells with group gathering stations. We also completed the 58-kilometre Gojalia–Paltana pipeline in Tripura, which transports natural gas to the OTPC Palatana Power Plant and thereby bolsters regional power availability.
Assam Renewal Project, one of the company’s largest infrastructure modernisation programmes executed for ONGC, where we revamped decades-old installations into advanced, integrated hydrocarbon facilities using advanced technology to extend life by at least 30 years. Under this project, we implemented comprehensive oil processing, storage, and supply systems, including a 467-kilometre oil and gas pipeline network that replaced an older 800-kilometre system and reduced advanced processing units from 21 to 9.
The project also featured a 64.5 MW captive power plant for enhanced energy self-sufficiency, a gas dehydration unit, group gathering stations, two water treatment plants, and two water injection facilities, all delivered under EPC mode. Operations are managed through a centralised remote-control system that enables real-time monitoring, automation, and a higher level of operational safety.
In Rajasthan, we laid a 42-kilometre gas pipeline and surface facilities in Gamnewala to transport natural gas to a gas collecting station, and we executed a 90 MMSCFD-capacity gas processing unit as part of the Raageshwari Gas Terminal in just six months for Cairn India. These projects demonstrate our capability to execute high-capacity gas infrastructure within compressed timelines while maintaining quality and performance standards.
Beyond core infrastructure, we champion sustainable operations by delivering three effluent treatment plants (ETP) at Mehsana, Gujarat, and Andhra Pradesh that comply with global environmental standards. These ETPs effectively separate oil from water to enable safe disposal or reuse, underscoring our commitment to environmentally responsible hydrocarbon operations.
Alongside, we also constructed storage tanks for Ahmedabad Asset, gas lift pressure upgradation at Ravva Oil Gas Field, and a six pipeline replacement project at Assam Asset. Together, these works further reinforce asset reliability, production continuity, and system integrity across key hydrocarbon fields.
Ongoing / Under-Construction International Projects
We are currently driving major international and national projects that showcase our large-scale execution capabilities. In Mongolia, we are executing the prestigious 1.5-million-tonnes Greenfield Mongol Refinery Project, a flagship India–Mongolia collaboration being implemented in extremely challenging climatic conditions. Our responsibilities span three critical segments, including the construction of the LPG Treating Unit, which purifies liquefied petroleum gas prior to distribution, and the Integrated Crude Distillation Unit, the primary facility that separates raw crude oil into valuable fractions such as gasoline and diesel. We are also building the saturated gas plant, steam turbine generators for power generation, and the sulphur block, along with associated offsite and utility facilities. This project is central to strengthening Mongolia’s energy security, reducing its dependence on imported fuels, and deepening long-term industrial and economic cooperation between India and Mongolia.
In Kuwait, we are establishing a new Gas Sweetening and Sulphur Recovery Facility for the Kuwait Oil Company to treat sour gas and recover sulphur to the highest environmental standards. This facility is designed to meet stringent emission norms while maximising sulphur recovery efficiency.
Ongoing / Under-Construction Projects in India
We are playing a major EPC role in HPCL Rajasthan Refinery limited, also known as HRRL, a joint venture between Hindustan Petroleum Corporation Limited and the Government of Rajasthan. In this 9 MMTPA project, we are executing multiple critical infrastructure packages that form the backbone of the complex. Our scope includes the Sulphur Recovery Unit, a key facility that captures and processes hydrogen sulphide to minimise environmental pollution, along with its necessary supporting infrastructure.
We are also executing India’s second-largest Polypropylene Unit with a capacity of 980 KTPA, along with a 59 KTPA capacity Butene-1 unit, associated conveying systems, and advanced bagging facilities.
In addition, we are building the world’s biggest single-train LLDPE/HDPE plant, with the ability to produce both linear low-density and high-density polyethylene resins for applications across packaging, automotive, and consumer sectors.
We are delivering advanced circulating fluidised bed combustion systems that enable efficient and environmentally responsible fuel utilisation. The project further includes steam turbine generators and associated systems, encompassing substation buildings, cooling towers, and emergency instrument air compressors to ensure reliable power and utility support.
As part of a landmark refinery development, we successfully laid two major cross-country pipelines, a 210-kilometre, 52-inch carbon-steel raw water pipeline and a 489-kilometre Arab-Mix crude oil pipeline, forming the backbone of refinery operations. Furthermore, we constructed the largest 66 KV gas-insulated substation for the refinery, and our work at the Rajasthan Refinery achieved the top ranking in Health, Safety, and Environment (HSE) performance among all units during 2024–2025.
Across India, we are also establishing specialised process units for other major refineries. At the Gujarat Refinery, we are constructing the Residue Fluid Catalytic Cracking (RFCC) unit, CR LPG Treating Unit, Propylene Recovery Unit, and Polypropylene Unit. At the Paradip Refinery in Odisha, we are executing offsites and utilities facilities, while at the Barauni Refinery in Bihar, we are delivering dedicated process units that increase refining flexibility and capacity. Together, these projects play a crucial role in expanding India’s refining capacity and strengthening energy infrastructure.
Our large-scale EPC efforts are strongly supported by our in-house manufacturing facility, which ensures quality assurance and the timely supply of essential machinery and equipment, including key vessels for the Gujarat Refinery and large pressure vessels exported to the Mongol refinery. Safety remains central to all operations, and we have recorded millions of safe man-hours, reflecting a deeply embedded culture of stringent safety practices and disciplined engineering.
