India’s Crude Oil Processing Dips Amidst Geopolitical Volatility and Scheduled Maintenance
Investors tracking the dynamic global energy market are closely observing India’s latest crude oil processing figures, which reveal a significant contraction in April 2026. Data indicates Indian refiners processed 21.39 million metric tonnes of crude oil, equivalent to 5.23 million barrels per day (mbpd), during the month. This represents an 8.9 percent downturn from the 23.48 million metric tonnes (5.55 mbpd) recorded in March. Furthermore, the April 2026 throughput also registered a 2.2 percent year-on-year decline compared to the 21.86 million metric tonnes processed in April 2025, signaling a challenging environment for the nation’s refining sector.
This slowdown in refining activity underscores the complex interplay of international geopolitical tensions and domestic operational adjustments. The downturn has direct implications for India’s energy security strategy and the profitability outlook for its major oil and gas players.
Geopolitical Headwinds Reshape Crude Sourcing Strategies
A primary driver behind the reduced processing volumes has been the escalating geopolitical conflict in West Asia. This ongoing instability has profoundly disrupted established crude sourcing patterns, compelling Indian refiners to recalibrate their supply chains. The repercussions of these conflicts, particularly those involving key players like the US and Iran, have reverberated across global energy markets, introducing considerable price volatility and logistical challenges.
Notably, shipping flows through the critical Strait of Hormuz, a maritime chokepoint responsible for transporting nearly one-fifth of the world’s crude oil and liquefied natural gas (LNG) supplies, faced significant disruptions. This heightened risk profile for traditional Middle Eastern crude routes has spurred Indian refiners to proactively diversify their import portfolios. Reports confirm a strategic pivot towards crude supplies from alternative regions, with increased reliance on shipments originating from Latin America and Africa to ensure continuity and mitigate supply vulnerabilities.
This shift, while enhancing energy security, can introduce new complexities related to crude grade compatibility, freight costs, and processing efficiencies, directly impacting refining margins and overall operational economics for the industry.
Operational Adjustments and Strategic Plant Turnarounds Impact Throughput
Beyond external geopolitical pressures, domestic operational factors, particularly scheduled maintenance shutdowns, played a crucial role in curbing April’s processing volumes. Refineries regularly undergo planned turnarounds for upkeep, upgrades, and and regulatory compliance, which temporarily reduce their operational capacity.
A significant instance involved Nayara Energy, partially owned by Russian oil major Rosneft. Its Vadinar refinery experienced an extensive period of planned maintenance throughout April, resulting in a substantial reduction in its processing activities. Consequently, the facility received only a single cargo of Russian crude during the entire month. This combination of routine maintenance and altered crude procurement patterns led to a dramatic drop in Nayara’s Vadinar refinery’s output to 502 thousand tonnes in April, a sharp decline from 1,654 thousand tonnes in March and 1,665 thousand tonnes in April 2025.
Additionally, the CPCL CBR refinery remains decommissioned due to persistent limitations in meeting required product specifications under its current configuration. Such strategic decisions to either reduce or cease operations at certain facilities further contribute to the national refining capacity landscape.
Key Refiners Navigate Volatile Market Dynamics
An examination of individual refinery performance offers deeper insights into the sector’s April challenges. Reliance Industries’ substantial Jamnagar complex, a cornerstone of India’s refining capacity, processed 2,475 thousand tonnes in April, down from 2,874 thousand tonnes in March. However, its overall year-on-year performance shows robust growth compared to 1,551 thousand tonnes in April 2025. Conversely, Reliance’s SEZ facility demonstrated resilience, processing 2,672 thousand tonnes in April, an increase from 2,543 thousand tonnes in March, though it registered a decline from 3,113 thousand tonnes in April 2025.
Among Indian Oil Corporation (IOC) refineries, most units reported reduced throughput in April compared to March. For instance, IOC Barauni processed 550 thousand tonnes (down from 578k in March, up from 476k in April 2025), IOC Koyali 1,442 thousand tonnes (down from 1,483k in March, up from 1,068k in April 2025), IOC Haldia 733 thousand tonnes (down from 764k in March, up from 701k in April 2025), and IOC Mathura 828 thousand tonnes (down from 895k in March, up from 825k in April 2025). Similarly, IOC Panipat saw 1,346 thousand tonnes (down from 1,411k in March, up from 1,322k in April 2025), IOC Guwahati 110 thousand tonnes (down from 114k in March, up from 100k in April 2025), and IOC Digboi 63 thousand tonnes (down from 66k in March, up from 37k in April 2025). IOC Bongaigaon processed 259 thousand tonnes (up from 233k in March, up from 230k in April 2025), while IOC Paradip processed 1,240 thousand tonnes (down from 1,330k in March, down from 1,362k in April 2025).
Bharat Petroleum Corporation Limited (BPCL) refineries largely maintained or slightly increased throughput month-on-month. BPCL Mumbai processed 1,282 thousand tonnes (up from 1,264k in March, up from 1,214k in April 2025) and BPCL Kochi 1,450 thousand tonnes (up from 1,427k in March, down from 1,512k in April 2025). BPCL Bina processed 649 thousand tonnes (down from 651k in March, down from 653k in April 2025).
Mangalore Refinery and Petrochemicals Limited (MRPL) Mangalore processed 1,442 thousand tonnes (down from 1,475k in March, down from 1,512k in April 2025), while Hindustan Petroleum Corporation Limited (HPCL) Mumbai processed 789 thousand tonnes (down from 896k in March, down from 831k in April 2025) and HPCL Visakh processed 1,288 thousand tonnes (down from 1,368k in March, down from 1,412k in April 2025). Other smaller refiners like CPCL Manali processed 910 thousand tonnes (down from 989k in March, down from 930k in April 2025), NRL Numaligarh 264 thousand tonnes (down from 291k in March, down from 277k in April 2025), ONGC Tatipaka 5 thousand tonnes (stable from March, stable from April 2025), and HMEL Bathinda 1,088 thousand tonnes (down from 1,171k in March, up from 1,067k in April 2025).
Investor Outlook: Navigating Challenges for Long-Term Growth
For investors focused on the oil and gas sector, these latest figures highlight the sensitivity of refining operations to both global and local factors. While the immediate dip in April’s crude processing indicates short-term headwinds, it also underscores the strategic importance of India’s energy infrastructure and its inherent resilience. The proactive diversification of crude sources by Indian refiners demonstrates a commitment to energy security amidst a volatile geopolitical landscape, a key consideration for long-term investment viability.
Looking ahead, the industry’s ability to optimize maintenance schedules, adapt to shifting crude supply dynamics, and manage geopolitical risks will be paramount. Investors should monitor developments in West Asia, changes in global crude trade flows, and the capital expenditure plans of major Indian refiners. Despite the momentary deceleration, India remains a critical growth engine for global energy demand, and its refining sector is poised for continued expansion, albeit with intermittent challenges that require astute market navigation.
