Samudra Manthan Scheme: Reduce India’s Oil Import Dependence

India is one of the world’s largest consumers of crude oil, but a major share of its energy requirement is met through imports. This dependence exposes the Indian economy to fluctuations in international crude prices, geopolitical tensions, supply disruptions and foreign-exchange pressures.

To strengthen India’s long-term energy security and unlock its offshore oil and gas potential, the Union Cabinet has approved ‘Samudra Manthan’ – the National Offshore Exploration Scheme, with an approved outlay of ₹84,084 crore up to FY 2030–31.

For UPSC and other competitive-exam aspirants, the scheme is important from the perspectives of Energy Security, Indian Economy, Blue Economy, Geopolitics, Hydrocarbon Exploration, Atmanirbhar Bharat and Environmental Challenges.

What is the Samudra Manthan Scheme?

Samudra Manthan is a Central Sector Scheme of the Ministry of Petroleum & Natural Gas focused on accelerating exploration and production of oil and natural gas in India’s offshore areas.

The name draws from the idea of Samudra Manthan—extracting valuable resources from the depths of the ocean. In the modern context, India intends to explore its deepwater and ultra-deepwater regions for hydrocarbon resources.

The Union Cabinet approved the scheme on 31 July 2026, with implementation planned through FY 2030–31.

The government describes it as India’s most ambitious offshore exploration mission to date.

Why Does India Need Samudra Manthan?

India’s economic growth is closely linked with reliable energy availability. However, the country remains heavily dependent on imported crude oil.

According to the Press Information Bureau, India is the world’s third-largest consumer of crude oil, with an annual crude-oil import bill of nearly US$144 billion, or approximately ₹13 lakh crore.

This creates several vulnerabilities.

1. Dependence on international oil prices

When global crude prices rise, India’s import bill can increase significantly. This can put pressure on:

Inflation
Current Account Deficit
Rupee stability
Transportation costs
Industrial costs
Household expenditure

2. Geopolitical risks

Oil-producing regions and major maritime routes are affected by geopolitical developments. Conflicts, sanctions or disruptions in shipping routes can create uncertainty for India’s energy supply.

3. Growing energy demand

As India’s economy expands, demand for transportation, manufacturing, electricity and other forms of energy is expected to increase.

Therefore, simply depending on imports may not be a sustainable long-term strategy.

4. Declining production from existing fields

The government notes that existing oil and gas fields experience a natural production decline of around 6–7% annually. Continuous exploration and new discoveries are therefore necessary to maintain and increase domestic production.

How Will Samudra Manthan Work?

The scheme takes a comprehensive approach rather than simply subsidising oil drilling.

It focuses on four major areas:

1. Offshore Seismic Data – ₹28,534 Crore

Before drilling a well, companies need to understand what lies beneath the seabed.

The scheme therefore provides ₹28,534 crore for acquisition and processing of modern offshore seismic data.

This includes:

2D seismic data acquisition: ₹12,000 crore
3D seismic data and other techniques: ₹12,534 crore
National Data Repository re-processing and AI tools: ₹4,000 crore

Better geological and seismic data can help identify promising areas and improve exploration efficiency.

2. Deepwater Exploration – ₹43,200 Crore

The largest component is dedicated to accelerating offshore exploration.

The scheme provides ₹43,200 crore for drilling 60 deepwater exploration wells.

Deepwater exploration is extremely expensive and risky. According to the government, a single deepwater exploratory well can cost approximately US$125–150 million.

To reduce this financial risk, the government will provide support of:

Up to 50% of eligible drilling cost or ₹675 crore per well, whichever is lower.

This risk-sharing mechanism is designed to encourage companies to undertake exploration in technically challenging offshore areas.

3. Common Offshore Infrastructure – ₹10,000 Crore

Discovering oil or gas is only the first step.

After discovery, companies require infrastructure for:

Production
Transportation
Processing
Evacuation of hydrocarbons
Connecting offshore fields to onshore facilities

Samudra Manthan therefore allocates ₹10,000 crore for common offshore infrastructure hubs.

The objective is to make commercialisation of discoveries faster and reduce duplication of infrastructure by individual companies.

4. Oil & Gas Manufacturing and Services Zones – ₹2,000 Crore

The fourth major component focuses on building India’s domestic capabilities.

The government has allocated ₹2,000 crore for Oil & Gas Manufacturing and Services Zones.

The objective is to promote:

Domestic manufacturing
Localisation of critical equipment
Offshore technology
Oil & gas services
Indigenous supply chains

This connects Samudra Manthan with the broader objectives of Make in India and Atmanirbhar Bharat.

Where Will India Explore?

India’s future offshore hydrocarbon potential is particularly important in deepwater and ultra-deepwater regions.

The government has identified areas including:

Krishna-Godavari Basin
Cauvery Basin
Mahanadi Basin
Andaman region

The opening up of offshore acreage is another important part of the strategy.

According to the government, more than 99% of previously classified offshore “No-Go” areas have been opened, making more than one million square kilometres of India’s Exclusive Economic Zone (EEZ) available for exploration.

What Does the ₹84,084 Crore Budget Include?

The overall allocation can be understood as follows:

Component	Allocation
Offshore data acquisition	₹28,534 crore
Offshore exploration acceleration	₹43,200 crore
Common offshore infrastructure	₹10,000 crore
Oil & Gas Manufacturing & Services Zones	₹2,000 crore
Monitoring & support activities	₹350 crore
Total	₹84,084 crore

The official allocation also includes digital interventions, monitoring, evaluation, human-resource development, awareness and outreach activities.

Can Samudra Manthan Really Reduce India’s Oil Imports?

This is perhaps the most important question.

The answer is potentially yes, but not immediately.

Samudra Manthan is an exploration-led strategy. Finding oil and gas offshore does not automatically mean that production will begin immediately.

Deepwater exploration can take years because it involves:

Survey → Data Analysis → Exploration Drilling → Discovery → Appraisal → Development → Production

The government notes that offshore hydrocarbon projects can typically take 5–10 years from awarding an exploration block to commencement of commercial production.

Therefore, Samudra Manthan should be viewed as a long-term energy-security mission rather than a quick solution to India’s current import dependence.

What Are the Government’s Targets?

Subject to successful exploration, the scheme aims to:

Increase domestic oil & gas production

India’s annual domestic oil and gas production is targeted to rise from approximately:

62 MMTOE → 80 MMTOE

Expand the hydrocarbon resource base

The resource base is targeted to increase from:

1.6 billion TOE → 2.2 billion TOE

Reduce the import bill

According to the government’s assessment, additional domestic production could potentially reduce India’s crude-oil import expenditure by nearly ₹1 lakh crore annually.

The Prime Minister’s Office also states that the scheme is expected to catalyse the addition of more than 600 million metric tonnes of oil equivalent (MMTOE) to India’s hydrocarbon reserves.

Samudra Manthan and India’s Energy Security

Energy security is much broader than simply producing more oil.

For India, it involves:

Reliable supply + diversified sources + domestic production + strategic reserves + infrastructure + renewable energy + technological capability

Samudra Manthan contributes primarily to the domestic production and exploration component.

If successful, increased domestic production could help India:

Reduce exposure to international crude-price volatility
Lower the petroleum import bill
Save foreign exchange
Improve energy resilience
Strengthen domestic industries
Create skilled employment
Develop offshore technology
Improve India’s strategic autonomy

Economic Significance of the Scheme

The impact of Samudra Manthan could extend beyond the petroleum sector.

Foreign Exchange Savings

Higher domestic production can reduce the quantity of crude oil that India needs to purchase from abroad.

Employment Generation

Offshore exploration requires expertise in:

Engineering
Geology
Geophysics
Data science
Shipping
Manufacturing
Construction
Oilfield services

This can generate both direct and indirect employment.

Manufacturing Growth

Demand for offshore equipment can support domestic manufacturing and localisation.

Technology Development

Deepwater exploration requires advanced seismic imaging, drilling technologies, AI-based interpretation and specialised offshore infrastructure.

This can strengthen India’s technological capabilities.

Environmental Concerns and Challenges

Samudra Manthan also raises important questions.

Deep-sea oil and gas exploration can involve environmental risks, particularly in ecologically sensitive marine areas.

Potential concerns include:

Oil spills
Damage to marine ecosystems
Underwater noise from seismic surveys
Disturbance to marine biodiversity
Carbon emissions from fossil-fuel consumption
Challenges associated with deepwater accidents

Therefore, expansion of offshore hydrocarbon exploration needs to be accompanied by strong environmental safeguards, impact assessments, emergency-response mechanisms and regulatory oversight.

At the same time, India’s long-term energy strategy cannot depend exclusively on hydrocarbons. Domestic oil and gas exploration can improve energy security while India continues its transition towards renewable energy, electric mobility, green hydrogen and other low-carbon technologies.

Major Challenges Before Samudra Manthan

Despite its potential, the scheme faces several challenges.

High exploration risk

Deepwater wells are extremely expensive, and exploration does not guarantee discovery.

Long gestation period

Commercial production may take years after exploration begins.

Technological requirements

Ultra-deepwater exploration requires advanced equipment, specialised expertise and international-level technology.

Environmental sensitivity

Marine ecosystems require careful management during seismic surveys, drilling and production.

Global oil transition

As the world moves towards cleaner energy, investments in new fossil-fuel infrastructure must also consider long-term demand and transition risks.
