Chevron is the second largest producer of oil in the Gulf of Mexico. It is the third largest producer of oil in the United States and 24 other countries. Their production worldwide has been quoted as 1.4 million barrels of oil and gas a day. Chevron's products are transported over land by pipeline and tankers, and over water by barges. The headquarters for this huge corporation is in Houston, Texas, but they also have offices in California, London, Singapore, Mexico, and Moscow to name a few. They have pipelines that extend across the United States and also in Africa, Australia, Indonesia, New Guinea, Europe, and the Middle East. In addition to oil and natural gas, Chevron is also one of the leading coal producers in the United States. The company is very interested in the environment and more than half of the company's reserves are of low sulfur coal. Chevron's latest accomplishment is geared towards capturing much of the oil reserves waiting to be found in Russia. Before the fall of the Soviet Union in 1991, Chevron had nearly signed a deal with the government to buy Tenghiz, the biggest oil field to become available in twenty years. Hug reserves of oil, approximately 250 billion barrels, were waiting to be taken from the earth. After the uprising in Russia, Chevron feared that the deal would be off. Fortunately, they were able to bargain with the new-found government and enter into a joint agreement to produce oil from the fields in Tenghiz. At this time, Chevron is planning to export the oil from Russia by pipeline to the Black Sea where it will be transported out by oil tanker. The cost of this entire deal will be somewhere in the area of $10 billion dollars. In 1991 Chevron had revenues of $40 billion dollars with a net income for the year of 1.3 billion dollars.
