On 17 April 2018 press reports indicated that provincial operator, Petrominera, signed an agreement with Chilean national oil company, ENAP-Sipetrol, to cede its 88% interest to CAPSA, owned by the Gotz family of Argentina, in the 123 sq km Pampa del Castillo-La Guitarra license in the San Jorge Basin. Petrominera ceded as well 7% of its interest to CAPSA for an amount of US$ 2.575 million. The deal has to be approved by the Chubut legislature. Petrominera will keep 5% interest of the block. The new contract includes the US$ 195 million investment by CAPSA for future development of the field. ENAP is currently producing an average of 2.82 Mbo/d in this mature field block. CAPSA is interested in this block as it operates the also very mature Diadema license adjacent to the field. In 2015, the Chubut provincial government approved a 10 year extension of the Sipetrol contract for the Pampa del Castillo-La Guitarra concession. ENAP will now concentrate on its ambitious Magallanes Area Incremental Project (PIAM) platform on the offshore 368 sq km Magallanes Block, Austral Basin, where it has invested to increase production. If this deal is finally completed, CAPSA will hold 95% and Petrominera 5% interest on the Pampa del Castillo-La Guitarra license.
