Brazilian state-run oil company Petrobras said on Feb. 2 it has tapped Joelson Falcao to become its new head of E&P, as the company announced a slate of new appointments as part of a management shake-up.

In a securities filing, Petrobras added that CEO Jean Paul Prates has also appointed William Franca as head of refining and natural gas and Claudio Schlosser as head of commercial and logistics.

Carlos Travassos was named as head of production development, it added, and Carlos Augusto Barreto as head of digital transformation and innovation.

The appointments remain subject to internal corporate governance procedures, a vote by an internal committee and a discussion at the company's board.
