Comodoro Rivadavia is a city in the Patagonian province of Chubut in southern Argentina, located on the San Jorge Gulf, an inlet of the Atlantic Ocean, at the foot of the Chenque Hill. Comodoro Rivadavia is the most important city of the San Jorge Basin.
The city is often referred simply as Comodoro. It has a population of 137,061 as of the 2001 census [INDEC]. Although there are rumours that say that by now, the population could be of as much as 200,000 inhabitants due to the growth the city has experienced in the last years because of the oil industry and construction.
The city was at one time the capital of Comodoro Rivadavia Territory, which existed from 1943 to 1955. The territory was a part of Chubut before and after its creation. The city is now capital of the Escalante Department.
Comodoro Rivadavia is a commercial and transportation center for the surrounding region, the largest city of Chubut, and an important export point for a leading Argentine petroleum district. A 1,770 km pipeline conveys natural gas from Comodoro Rivadavia to Buenos Aires. The city is modern with the air of an oil-country boomtown.
