Our work in Timor Leste

We have been in present in the country since 2006, and today we operate in the Exploration & Production sector, holding stakes in four offshore blocks.


Timor-Leste was declared an independent nation on 20 May 2002 after voting to secede from Indonesia on 25 October 1999. Until 2018, both Timor-Leste and Australia claimed sovereignty over the Timor Sea area that includes Bayu-Undan, previously known as the Joint Petroleum Development Area (“JPDA”). In 2019, Australia and Timor-Leste ratified a treaty to establish maritime boundaries in the Timor Sea (“Maritime Boundaries Treaty”). Timor-Leste has sole jurisdiction over the ownership and management of certain hydrocarbon fields in the former JDPA area, including Bayu-Undan and Kitan.

Development and exploration of wells

Eni has 4 PSCs in Timor Leste, it operates TL-SO-19-10, -11 and SO6-04. While in TL-SO-19-13 it is a non operated partner and holds the giant Bayu Undan field. Production comes mainly from the Bayu Undan gas and liquid field with a production of 113 kboe/day (9 kboe/day net to Eni) in 2021. Liquid production is supported by two treatment platforms and an FSO unit. Production of natural gas is carried by a 500 kilometer long pipeline and is treated at the Darwin liquefaction plant which has a capacity of 3.6 mmtonnes/year of LNG (equivalent to approximately 177 bcf/year of feed gas). LNG is sold to Japanese power generation companies under long-term contracts. In May 2021, through our subsidiary Eni Australia Limited, we signed with Santos a non-binding Memorandum of Understanding (MoU) to jointly seek cooperation opportunities in the following areas, that amongst other items includes including the options to repurpose and extend the life of Bayu Undan.

Encouraging local development

Our initiatives in the countries we work in are based on an integrated approach involving local communities and partners, sharing our skills and funds with them. In line with the UN's Sustainable Development Goals, our initiatives help provide access to energy, water and sanitation, diversify the economy, give education and professional training, protect the landscape and improve health services for communities. In East Timor we are running initiatives to diversify the economy (in line with SDGs 2, 8 and 10).
