Brazilian energy giant Petróleo Brasileiro S.A. (Petrobras) is deeply involved in the global oil and gas industry, conducting exploration, production, and sales activities both within Brazil and internationally. The company's diverse operations are organized into four primary business segments: Exploration and Production; Refining, Transportation, and Marketing; Gas and Power; and Corporate and Other Businesses.

Overall, Petrobras’s activities span the entire hydrocarbon value chain. This includes the search for and extraction of crude oil from various sources—onshore, offshore, and unconventional formations like shale—along with its subsequent refining, processing, trading, and distribution.

The company also manages natural gas, other liquid hydrocarbons, and refined petroleum products. Specifically, the Exploration and Production division focuses on discovering, developing, and extracting crude oil, natural gas liquids, and natural gas, primarily to supply the company's domestic refineries.

The Refining, Transportation, and Marketing segment handles the refining, logistics, transport, commercialization, and trading of crude oil and various refined petroleum products. This unit is also responsible for ethanol exports, the extraction and processing of shale, and holds equity interests in petrochemical companies.

The Gas and Power segment manages the logistics and trading of natural gas and electricity, including the transportation and commercialization of Liquefied Natural Gas (LNG). It generates electricity via thermoelectric power plants, holds stakes in natural gas transmission and distribution networks, and is engaged in both fertilizer manufacturing and natural gas processing.

Finally, the Corporate and Other Businesses segment is dedicated to the production of biodiesel and its associated co-products, as well as ethanol, in addition to the distribution of various petroleum products. Petrobras was established in 1953 and its corporate headquarters are located in Rio de Janeiro, Brazil.
