Southeast Asian governments and national oil companies in recent times have made some key appointments with the aim of improving energy security, strengthening their upstream industries and increasing investment.

Indonesia’s President Joko Widodo (Jokowi) has ordered the overhaul of Pertamina’s management, as former Opec member Indonesia seeks to reduce costly crude oil imports to help the state’s coffers.

Jokowi has appointed ex-Jakarta governor Basuki Tjahaja Purnama — known locally as Ahok — to take the reins at state-owned oil and gas company Pertamina while Emma Sri Martini will be the company’s new chief financial officer, replacing Pahala Mansury.
