Discovered in 1995, the Bayu-Undan field plays a vital role in ConocoPhillips’ Australian operations.

Bayu-Undan is a gas-condensate field located offshore in Timor-Leste offshore waters.

The field is 250 kilometres south west of Suai in Timor-Leste and 500 kilometres north west of the Northern Territory in Australia. ConocoPhillips operates the field on behalf of co-venturers Santos, Inpex, ENI, Tokyo Timor Sea Resources, a consortium of Tokyo Gas and JERA (a joint venture between Tokyo Electric and Chibu Electric).

ConocoPhillips highly values its relationship with Timor-Leste and is proud of the benefits that Bayu-Undan has delivered to the country over the past 16 years. 

Bayu-Undan has provided training opportunities and created employment for many Timorese men and women, giving them exposure to a high standard oil and gas working environment both offshore and onshore. Our focus on capacity building and increasing on the job experience has resulted in Timorese progressing into more skilled and professional roles, and a significant increase in the workforce capacity. We also place a high priority on sourcing goods and services from Timor-Leste, which has become more successful as the capacity of work being done in the country has increased. Additionally, we have a community investment program which provides direct benefits to many Timorese communities across the country. 

Bayu-Undan has been a very successful project for all stakeholders and the field is entering the final phase of its life cycle. Once the end of economic production is reached for the project, currently projected for to be sometime within the 2021 to 2023, a decommissioning project will take place.

The Bayu-Undan project has contributed more than US$20 billion in taxes and other payments* to the Timor-Leste Petroleum Fund since 2004. We have also invested a further $146 million through local content activity including employment and training, procurement and community investment*.

The Field

The Bayu-Undan field includes a Central Production and Processing complex (CPP) consisting of two platforms – Drilling, Production and Processing (DPP); and Compression, Utilities and Quarters (CUQ). The field also includes a Floating, Storage and Offloading facility (FSO) two kilometres from the CPP and an un-manned wellhead platform (WP1) seven kilometres east of the CPP.

Bayu-Undan field development  has occurred in three phases. Phase one commenced in 2004 with the construction of offshore facilities to produce and process condensate, propane and butane (LPGs). This phase also saw a total of 13 wells drilled for production, gas injection and water disposal.

Phase two, completed in 2006, saw the installation of a subsea pipeline and the LNG production facility. The 500 kilometre 26” pipeline supplies gas from Bayu-Undan for processing into a 3.7 MTPA design capacity LNG facility – Darwin LNG, located in the Northern Territory of Australia . LNG is loaded onto specialised tankers for transport to international markets.
