Digboi Oil Refinery: A Century of Resilience

Introduction

Built on December 11, 1901, the Digboi refinery in Assam is not only the oldest oil refinery in India but also the oldest operating oil well in the world. Nestled in the remote northeastern corner of the country, this refinery has witnessed over a century of transformation, innovation, and resilience.

Discovery of Oil

Early Beginnings

• The use of oil dates back centuries. Herodotus, the ancient Greek historian, mentioned natural asphalt being employed in the construction of Babylon’s walls and towers more than four thousand years ago.
• In China, petroleum was already in use over 2000 years ago. The I Ching, an early Chinese text, cites the use of raw oil without refining.

Colonel Edwin Drake and the Oil Boom

• The modern era of oil exploration began with Colonel Edwin Drake in 1859. He discovered oil at Oil Creek, Pennsylvania, which touched off an oil boom.
• Drake’s discovery led to the establishment of the world’s first refineries and modern oil wells. It marked the beginning of the oil economy.

James Young’s Observation

• In 1847, Scottish chemist James Young observed natural petroleum seepage in the Riddings coal mine.
• From this seepage, he distilled both a light, thin oil suitable for lamps and a thicker oil suitable for lubrication.

Global Impact

• The discovery of oil had far-reaching consequences. It fueled the explosive growth of the industry, especially with the rise of internal combustion engines for automobiles and trucks.
• Oil became a critical factor in military strategy during World War II when diesel fuel replaced steam engines in warships.

Legacy and Controversy

• Oil’s dominance continued throughout the 20th century, but issues like air pollution led to government regulation.
• In the 21st century, environmental concerns, including global warming, make the oil industry politically controversial.

Birthplace of the Indian Oil Industry

Commissioning and Pioneering Spirit

• On December 11, 1901, the Digboi refinery was commissioned, marking a historic moment. It became Asia’s first refinery, blazing a trail for the entire Indian oil sector.
• The refinery’s establishment was a testament to human ingenuity and the spirit of exploration.

Assam Oil Company and Evolution

• Initially, the Digboi refinery was owned and operated by the Assam Oil Company Limited. Later, it transformed into the Burmah Oil Company.
• This transition laid the groundwork for its eventual integration into the Indian Oil Corporation Limited (IOC).

Legacy and Continuity

• Despite its age, the Digboi refinery remains operational, making it the world’s oldest operating oil well.
• Its legacy extends beyond India, symbolizing the birth of an industry that has shaped economies and societies worldwide.

Gangotri of the Indian Hydrocarbon Sector

The Sacred Parallel

• Much like the revered Ganges River (Ganga), which is considered the source of life in Hindu mythology, the Digboi refinery holds a similar status in the hydrocarbon sector.
• Just as the Ganges nourishes the land and its people, Digboi symbolizes the birth and sustenance of India’s oil industry.

Historic Legacy

• The title of “Gangotri” signifies not only its age but also its pioneering role. Digboi was Asia’s first refinery, setting the stage for the entire Indian oil landscape.
• Its legacy transcends national boundaries, making it a historic landmark recognized globally.

In summary, the Digboi Oil Refinery stands as a sacred source, channeling energy and progress—a testament to human ingenuity and the enduring impact of hydrocarbons.
