Oil and natural gas exploration and production are our core activities. We seek to increase our reserves and develop production to make sure we can meet the increased demand for energy. Our oil and natural gas exploration and production activities are the major components of our portfolio and include offshore and onshore exploration, appraisal, development, production and incorporation of oil and natural gas reserves. With technology and the persistence of our employees, we overcome challenges that once seemed impossible, such as the deep waters of the Campos Basin, in the 1970s. Today, production in deep pre-salt waters is already a consolidated reality. Our activities are focused on deepwater and ultra-deepwater oil reservoirs in Brazil, which accounted for 95% of our total production in 2021.
Like most major oil and gas companies, we operate in partnerships using E&P consortia in the exploration of blocks and the production of oil fields in Brazil, mainly in ultra-deepwaters.
Most of our oil reserves are in offshore fields, which has led our drilling activities to reach ever-greater depths.
