Anzon restarts Basker/Manta operations

ANZON Australia says the installation vessel CSO Venturer has arrived at its $330 million Basker/Manta (BMG) oil project in the Bass Strait, recommencing field operations.

The Sydney-based company yesterday said the construction and diving support vessel has now installed the 70 tonne subsea manifold, which controls production from the project’s four completed Basker wells and one completed Manta well.

“The CSO Venturer has commenced the installation of the flowline to Manta 2A and will complete the installation of all other subsea equipment, subject to weather, in the next four weeks,” the company said.

Anzon said its floating processing storage and offtake (FPSO) vessel, Crystal Ocean and the storage/offtake tanker Basker Spirit are now in Singapore undergoing final modifications.

Crystal Ocean was this week fitted with a 7500hp compressor and associated facilities to allow it to handle the 35 million cubic feet a day produced with the oil. It will also enable gas re-injection into the Basker reservoir until the new gas project comes online.

Anzon said it expects to hook it up to the existing flowline to the manifold in the first week of November.

Meanwhile, the company said Basker Spirit had a new 14 metre bow loading extension installed while in Singapore to increase the distance of the offshore mooring from the vessel's below-the-waterline bulbous bow.

Anzon and joint venture partner Beach Petroleum are also using the dry-docking to carry out the ship's mandatory five-yearly certification inspection.

“Efforts are being made to have the Basker Spirit transport and deliver a load of fuel oil from Singapore to a location in Australasia to defray the cost of the return journey,” Anzon said.

The Basker Spirit is scheduled to return to the Bass Strait mooring in time to receive production from the Crystal Ocean.

Anzon last month upgraded BMG's gross 2P oil reserves by 32% to 40 million barrels (MMbbl), while total reserves and resources jumped some 121% to 119.8 million barrels of oil equivalent (MMboe).

It also said BMG is scheduled to commence full oil production at a peak rate of about 25,000 barrels of oil per day (bopd), while net oil production is expected to rise from 1.2MMboe in 2006.

This is expected to jump to 4.3MMboe by 2008.

Anzon is aiming to have first commercial gas flow from BMG in January 2008, with a project life to 2020.

BMG lies 70 to 75 kilometres offshore southeastern Victoria, in a water depth of about 110 to 200 metres.

Anzon and Beach Petroleum each hold a 50% stake in the joint venture.
