The London-listed firm said Perks would bring more than three decades of experience in the upstream oil and gas sector, having held senior roles at BG Group, Anadarko and Total.
At Anadarko and later Total, he played a central role in delivering the $20bn Mozambique LNG project, taking it to final investment decision after extensive engagement with the government.
He previously oversaw BG’s $10bn Queensland Gas Company LNG project in Australia, delivered on schedule and within budget, and led operations in Tunisia and Trinidad and Tobago.
“I am delighted to welcome Ian to Tullow as CEO; he brings a wealth of industry and African knowledge and experience and has a track record of successfully managing large multi-stakeholder businesses and projects,” said Phuthuma Nhleko, chairman of Tullow.

Perks said he was joining the company at a critical juncture in its development.
“My near term priority will be to work with Richard, the Tullow team and our stakeholders to put the company on a long-term sustainable financial footing,” he said.
“We will then have an opportunity to grow the Company across Africa, leveraging our current assets and reputation on the continent of Africa to add value for our stakeholders.”
