On 16 August 2019, the National Oil, Gas and Biofuel Agency (ANPG), Cabinda Gulf Oil Company Limited a wholly owned subsidiary of Chevron and Sonangol E.P. signed a cooperation protocol for the study and evaluation of Block 33.  Block 33 currently does not have an operator, should the results of the study prove promising Chevron may assume this role, with Sonangol as a partner.  The 4,936 sq km block located primarily atop the Congo Fan plays host to a small oil discovery - Calulu 1 - discovered in the early 2003 by Esso Exploration Angola (Block 33) Ltd. Water depths across the block range between 1,500 and 2,500 m.  Itâs worth noting that this is the second study protocol signed by Chevron this year - in June the company signed a similar agreement for Block 34.
