Description
 
Located about 310 miles (499 kilometers) northwest of Darwin, Australia and 155 miles (249 kilometers) south of Suai on the southern coast of East Timor Sea in waters measuring about 260 feet (79 meters) is the Bayu-Undan project. Straddling permits PSC 03-12 and PSC 03-13 in the Joint Petroleum Development Area between Timor-Leste and Australia, the project is estimated to contain reserves of 400 million barrels of condensate and 3.4 Tcf of gas.

The Bayu-Undan field was discovered in early 1995 with the drilling of the Bayu-1 well in area 91-13 in the Timor Gap Zone of Cooperation. Shortly after, another well, Undan-1 was found in the nearby area 91-12. This discovery, roughly 6 miles (10 kilometers) from the Bayu-1 well, confirmed the field as a large accumulation.

Considered to be one of the most innovative and technically complex offshore facilities ever undertaken in the petroleum industry, the Bayu-Undan project involves a two-phase development of the field's gas and gas liquids resources. Receiving governmental approval from the Timor Gap Joint Authority in 2000, the project began development in 2001 and is expected to produce until 2026.

Development

For a total cost of $2.5 billion, the Bayu-Undan project was carried out through two phases. Phase 1 included a natural gas recycle project, in which condensate and natural gas liquids were separated and removed for sale, and dry natural gas was re-injected back into the reservoir until Phase II (Darwin LNG) was ready to receive hydrocarbons.

The first phase of development focused on the gas recycle facility to produce and process wet gas; separate and store condensate, propane, butane; and re-inject dry gas back into the reservoir. At maximum design rates, the facility produces 1.1 Bcf of gas; 115,000 barrels of combined condensate, propane and butane; and 950 MMcf/d of dry gas recycled into the reservoir on a daily basis.

The liquids are sent and processed at the Bayu-Undan facilities, consisting of three primary components: a Central Production and Processing Complex (CPP), an unmanned Wellhead Platform, and an FSO. The CPP compromises two separate platforms linked to each other by bridge. The platforms are the Drilling, Production and Processing (DPP) Platform, and the Compression, Utilities and Quarters Platform (CUQ). The combined topsides facilities weigh close to 26,000 metric tons and they sit on top of two eight-pile steel jackets.

The DPP platform provides roughly two thirds of the 1.1 billion standard cubic feet per day of raw liquid rich gas from the reservoir via four production wells. It also provides the processing facilities to separate the well fluids into gas and liquid products.

Providing the compression facilities for the processed gas to be either re-injected into the reservoir or exported to shore via a subsea pipeline is the CUQ platform. The platform also contains living quarters for 80 personnel.

Located 4.5 miles (7.4 kilometers) to the east of the CPP platform is the unmanned wellhead platform (WPI). The platform is a second production center for the field and supplies roughly one third of the 1.1 billion standard cubic feet per day of raw liquid rich gas to the DPP platform via a subsea pipeline. Twenty-two wells were drilled from the DPP and WPI centers, and liquids are exported from the WPI for processing on the CPP.

Designed to store three separate liquids, the project's FSO is equipped with refrigeration, liquefaction, and gasification facilities and can store 820,000 bbl of condensate, 300,000 bbl of propane, and 300,000 of butane. The FSO is turret-moored 1.2 miles (2 kilometers) from the CPP and linked to it by four pipelines carrying condensate, butane and propane as well as fuel gas for power generation.

Following the completion of the first phase of development, the second phase commenced. Phase II of the project involved installing a natural gas pipeline from the field to Darwin, Australia, and constructing a new LNG facility, located at Wickham Point, Darwin. This phase will also drill additional wells for further field development in 2009 and will continue through 2010.

Production

Production of LPG and condensate from the project commenced on March 30, 2004, and LNG production from the Darwin LNG plant commenced in February 2006.
 
Activities
 
FMC to Supply Subsea Equipment for Bayu-Undan Third Phase
Date: May. 2013
Type: Development Activity
In anticipation of the third development phase of the Bayu-Undan gas field in the Timor Sea, ConocoPhillips issued a $26 million contract to FMC Technologies for the supply of long lead items such as subsea trees, wellheads, jumper kits and associated control systems. Detailed engineering and additional procurement activities will begin once the field partners announce the final investment decision mid-2013. Additionally, the partners are seeking a suitable semisubmersible to carry out the third phase development drilling program which is expected to begin 2Q 2014.
Clough AMEC to Provide Operations, Support Services to Bayu-Undan Project
Date: Oct. 2011
Type: Contract Award
ConocoPhillips granted Clough AMEC a two-year contract extension to provide operations and support services to the Bayu-Undan facilities located in the Timor Sea. The work scope includes implementation engineering, work package preparation, planning, hazard assessment, coordination, offshore field services and implementation. The Bayu-Undan gas field is situated in a water depth of 262 feet (80 meters) offshore Australia. ConocoPhillips operates the development with 57.20 percent interest.
Neptune to Provide Services for ConocoPhillips' Timor Sea Facility
Date: Dec. 2009
Type: Contract Award
ConocoPhillips awarded a combined services contract to Neptune Marine Services for the Bayu-Undan Gas Recycle Facility in the Timor Sea. The scope of work includes a program of pipeline inspection surveys, remotely operated vehicle (ROV) inspection of the facility’s pipelines and platform and grouting services. Situated in a water depth of 262 feet (80 meters), the Bayu Undan gas field came online in 2004.
ConocoPhillips Announces First Liquids Production from Bayu-Undan
Date: Feb. 2004
Type: Production Start
ConocoPhillips [NYSE:COP] today announced that first liquids production began February 10 from the Bayu-Undan field in the Timor Sea Joint Petroleum Development Area (JPDA). Liquids production is the first phase in this two-phase project. In this first phase, the Bayu-Undan gas recycle facility will produce and process wet gas; separate and store condensate, propane and butane; and re-inject dry gas back into the reservoir. Full daily design rates of 1.1 billion cubic feet of gas; 115,000 barrels of combined condensate, propane and butane; and 950 million cubic feet of dry gas recycled into the reservoir are anticipated to be reached by the third quarter of 2004.
