TPAO

Türkiye Petrolleri Anonim Ortaklığı (TPAO) (Turkish Petroleum Corporation) was founded in 1954 by Law No. 6327 with the responsibility of being involved in hydrocarbon exploration, drilling, production, refinery and marketing activities of oil and gas in Turkey as the national company.

Being an important actor of the national economy, TPAO achieved many “firsts” of the Turkish oil industry. The company, its history reaching back over a half century, has given rise to seventeen major companies, including Petkim, Tüpraş and POAŞ to Turkey.

Until 1983, as an integrated oil company, it was engaged in all the activity fields of oil industry from exploration to production, refinery, marketing and transportation. Today, TPAO is a national oil company involved in merely upstream (exploration, drilling, well completion and production) sector. Provided by Wikipedia
