The three refineries were integrated in 1997. The nameplate capacity of 956,000 barrels per day represents 74% of Venezuela's total refining capacity.

The product mix is as follows: distillates, 43%; gasoline, 28%; fuel oil, 24%, naphtha, 5% and others 1%. It serves both the domestic and export markets. The complex is part of a major petrochemical expansion project to produce olefins and aromatics, which is due for completion in 2014.

SK Energy Ulsan, South Korea

Owner:SK Energy

Nameplate capacity:840,000 barrels per day

Current capacity:840,000 barrels per day

The Ulsan refinery is the world's second largest refinery and the largest in Asia. SK Energy is the oldest and largest refiner in South Korea. Some 57% of the refinery's output serves the domestic market with the remainder going for export.

It produces diesel, gasoline, LPG, kerosene, naphtha, asphalts, propylene and slurry oil.

RIL Jamnagar, India

Owner:Reliance Industries Limited (RIL)

Nameplate capacity:661,000 barrels per day

Current capacity:650,000 barrels per day

Future nameplate capacity:1,650,000 barrels per day (following expansion)The Jamnagar refinery is fully integrated with associated downstream petrochemicals units, which manufacture naphtha-based aromatics as well as propylene-based polymers.

Situated on the northwest coast of India, the complex is located at Motikhavdi, Lalpur Taluka, Jamnagar District, in the state of Gujarat. It is near the Gulf of Kutch, close to Middle-East crude sources.

The new refinery being constructed on an adjacent site will process low quality crude with all output destined for export. Once completed, this will make Jamnagar the world's largest single refining complex.

The existing refinery has over 50 process units carrying out crude oil distillation (atmospheric and vacuum); catalytic cracking; catalytic reforming; and delayed coking.

GS Caltex, Yeosu, South Korea

Owner:GS Holdings,

Chevron (50% each)

Nameplate capacity:670,000 barrels per day

A US$1.5 billion upgrade programme was completed in 2007 to increase production of high-value products by 33,000 barrels per day, adding 15,000 barrels per day in new lubricants production and to reduce costs through the processing of cheaper, heavier crude oils.

Plans have also been announced for a US $3 billion-plus new upgrade unit to be installed by 2010.

ExxonMobil, Singapore


Nameplate capacity:605,000 barrels per day

The refinery also manufactures industrial and automotive lubricants.

Throughput at Jurong is 309,000 barrels per day and 296,000 barrels per day at Jurong Island.

The site employs a total of 740. it can handle a wide range of crudes and operate at different rates of feed in order to meet different requirements. It produces 15 grades of gasoline, 10 grades of jet/diesel, 10 grades of chemicals and 5 grades of fuel oil. Baton Rouge, US
