Jamnagar is today known as 'Oil City' because the world's biggest oil refinery belonging to Reliance Industries and a smaller one belonging to Essar Oil are located in Jamnagar. It was earlier known as 'Brass City', the city housing more than 5,000 large scale and 10,000 small scale units manufacturing brass items in and around the industrial estates of Shankar Tekari, Udhyognagar, M P Shah Udhyognagar and Dared. There are about 4,500 units of Brass Part in Jamnagar district supplying their products to major electric and electronic factories located in Delhi, Bangalore and Mumbai
The Jamnagar Refinery is a private sector crude oil refinery owned by Reliance Industries Limited in Jamnagar, India. The refinery was commissioned on 14 July 1999 with an installed capacity of 661,000 barrels per day (105,100 m/d). It is the largest refinery in the world. The refinery is currently undergoing massive expansion, scheduled for commissioning in 2008, that will double its capacity to 1.2 million barrels per day (190,000 m/d).
According to an article in the 28 April 2008 issue of Fortune Magazine, the world-class Reliance Industries oil refinery at Jamnagar will output 1.2 million US gallons (4,500 m) of petroleum, or 5% of the world's capacity, after an expansion is completed in December 2008. The expansion had begun in October 2005 and is managed by San Francisco-based Bechtel Corporation. The expanded refinery consumes an area equal to 1/3 the size of Manhattan. The refinery is advanced in that it can process a wide range of crude oils, including heavy high-sulfur sour crude, which many refineries cannot handle. Reliance Industries has said that the refinery's output is for export only, and will not be sold domestically within India. Reliance is targeting the U.S. market for gasoline and the European market for diesel. The refinery is owned by Reliance's Reliance Petroleum Ltd. unit, in which U.S. oil company Chevron Corp. has a 5% stake.
