In 1993, INPEX acquired an interest in the former JPDA03-12 contract area, which was jointly managed by Australia and East Timor. Exploration within this contract area resulted in the discovery of oil and gas fields. Studies revealed the Undan and Bayu structures, located in the adjacent former JPDA03-13 contract area, to be a single structure. In 1999, the interest holders unitized both contract areas into the Bayu-Undan Gas-Condensate Field. As a result of the ratification of a maritime boundary treaty between Australia and East Timor, a new production sharing contract (PSCTL-SO-T 19-12) was agreed with East Timor in 2019. Hydrocarbons from the Bayu-Undan Gas-Condensate Field were previously used to produce and ship condensate, LPG and LNG. Currently, the Bayu-Undan Project produces gas for sale to the Australian domestic market. As a climate change response measure, the project is considering a project to capture, inject and store CO2 emitted from the Barossa Gas Field located in waters northwest of Australia and other Oil and gas fields by reusing the production facilities of the Bayu-Undan Gas-Condensate Field after the termination of production, along with the Darwin LNG facilities.
