Pluto

Discovered in April 2005, the Pluto gas field is located on permit WA-350-P and license WA-34-L, about 118 miles (190 kilometers) northwest of Karratha on the coast of Western Australia. The massive gas find is expected to hold 4.4 Tcf (125 Bcm) of recoverable dry gas reserves.

Reaching a total depth of 10,827 feet (3,300 meters), the Atwood Eagle semisub drilled the Pluto-1 discovery well in 3,202 feet (976 meters) of water. Preliminary analysis indicated a gas column measuring 686 feet (209 meters), and a subsequent production test established a stabilized gas flow of 9.5 MMcf/d (.27 MMcm/d) through a 28/64-inch choke. Analysis of the wireline log data on the Pluto-1 well showed the well encountered gas pay in the Triassic, Lower Jurassic, Mungaroo and Brigadier formations.

Drilled to a total depth of 10,942 feet (3,335 meters) by the Sedco 703 semisub, the Pluto-2 appraisal well is located 5.3 miles (8.5 kilometers) south of the discovery well. Spud on July 21, 2005, the well confirmed the southerly extent of the field by encountering a gas column measuring 207 feet (63 meters).

Xena

Also located on WA-350-P and WA-34-L, Xena was discovered in September 2006. The Jack Bates semisub drilled the Xena-1ST1 exploration well to a total depth of 11,450 feet (3,490 meters). Located 4 miles (6 kilometers) east of the Pluto-2 appraisal well in 584 feet (178 meters) of water, the Xena discovery well encountered a gas column of 161 feet (49 meters) in good-quality reservoir sandstones.

Drilled by the Ocean Bounty semisub in the first quarter of 2008, two appraisal wells on the Xena field, Xena-2 and Xena-3, confirmed the field and established the presence of gas-saturated sands in another fault block. Xena is estimated to contain 600 Bcf (17 Bcm) of recoverable dry gas.

Field Development

Approved by Woodside in July 2007, the US $11.2 billion (A$12.4 billion) field development plan includes five subsea big bore wells producing to a shallow-water production platform 17 miles (27 kilometers) away. Gas will be transported from the fixed platform through 112 miles (180 kilometers) of pipeline to an onshore LNG plant. A single-train LNG processing facility, the new Burrup LNG Park will have a production capacity of 4.7 million tons (4.3 million tonnes) a year, as well as an export jetty and storage facilities.

With plans submitted to the state and federal authorities in August 2005 for major project facilitation, the project was approved by the government in September 2005. Soon afterward, front-end engineering began on the project in November 2005.

Located in 2,723 feet (830 meters) of water, the five subsea wells are being developed through subsea trees linked to two subsea production manifolds. For a consideration of $200 million, FMC was awarded the contract to provide the subsea system for the Pluto project, including the subsea trees, manifolds, and related control and tie-in equipment. In two separate contracts, FMC then subcontracted to Grenland Group for the fabrication, assembly and testing of some of the structures on the project.

Situated in 279 feet (85 meters) of water, the remotely operated platform is a riser and gas export platform with the capacity to transfer 1.6 Bcf/d (45 MMcm/d) of natural gas. The platform consists of a four-leg extended base tower that weighs 11,023 tons (10,000 tonnes) and topsides. KBR's subsidiary Eos was awarded the FEED contract for the platform and in a joint venture with Worley Parsons, was awarded the detailed engineering, procurement management and construction management for the platform. Ferguson Modular was awarded a contract to supply a 16-person accommodation complex for the platform. In January 2008, J. Ray McDermott was awarded the installation engineering, transportation and installation of the platform.

Spanning 112 miles (180 kilometers), a 36-inch-diameter flowline will transfer gas from the platform to the onshore LNG facility. Poyry was tapped to provide flow assurance and process engineering for the flowlines involved in the project. In a US $15 million (NOK 105 million) contract, Aker Solutions was chosen to provide the 17 miles (28 kilometers) of steel tube umbilicals for the project. For $150 million, Acergy was awarded the installation work on the project, which includes the subsea manifolds, valve structures, umbilicals, injection line and pipeline stabilization, as well as the flowline tie-ins.

Production

Production is scheduled to commence in early 2012, and first LNG by that same year. There are a number of offshore permits in the area that will undergo exploration and may add to the project's production. Additionally, considerable investments have been made on the project to facilitate future expansion of the LNG facility for third-party gas.

Pluto Expansion

In November 2009, Woodside awarded dual FEED contracts for Pluto train 2 and 3, compromising the same scope of work, to a Foster Wheeler Worley Parsons joint venture and KBR. The FEED studies were completed in mid-2010.

The 20-plus-exploration campaign to support Pluto expansion commenced in October 2009. Woodside continues to explore the area in order for new discoveries to contribute to an expansion of the foundation Pluto LNG project. A final investment decision on Pluto Train 2 and 3 was expected by the end of 2010 and at the end of 2011, respectively.
