Map showing oil and gas field locations

The Timor Sea is divided between East Timorese, Australian, and Indonesian territory, as explained in the May and July 2002 La’o Hamutuk Bulletins. The map below, from the July Bulletin (explanation of map terms), shows the location of each field and relevant boundaries, both from the Timor Sea Treaty (JPDA) and from historical and legal references.

The Northern Territory Government (Australia) has published a map. Click on the thumbnail image at right to get a bigger image in a separate window. In August 2003, the NT government published a number of fact sheets, including Timor Sea Oil and GasTimor Sea Oilfields, and Timor Sea Gas Discoveries.  The Timor Sea one is also available as PDF.



The following graph shows the amount of oil and gas resources remaining in each field as of the middle of 2002, plus which international oil companies have signed production-sharing contracts (PSC's) with the Australian and/or East Timorese governments to allocate the oil resources.

Click on a company or oilfield name in the following graph to go directly to more information about it.

Since the above graph was prepared, shares in Bayu-Undan have been sold to Tokyo Electric Company and Tokyo Gas Company, and shares in Laminaria-Corallina to Paladin llc and then to Talisman.

How the ownership of the fields has changed over time

This table shows the percentage of the upstream revenues Timor-Leste will be entitled to under the different legal regimes proposed from 1999 through 2006.
