dana lws

Dubai-based Momentum Group has completed installation of the Dana LWS (lightweight structure) for PCPP in the Dana field, offshore Sarawak, East Malaysia. Momentum used the Seadrill jackup drilling rig West Janus rather than employing a significantly more expensive derrick barge.

The combined weight of the unit comprising jacket, platform and boat landing was 300t, installed in a 50m water depth approximately 150km from Bintulu.

The Dana LWS installation is part of a PCPP contract awarded to Momentum in 2Q 2011 that also entailed fabrication of the Dana wellhead support frame, D35 deck extension and pipeline end manifold (PLEM) and involved Kencana HL, a division of Kencana Petroleum.

The Dana and D30 fields, both in block SK 305, are being developed together with two bridge linked MOPU (mobile offshore production units).

Petronas has embarked on a Small Field Risk Service Contract for development of the Balai Cluster fields in cooperation with a contractor group comprising Roc Oil Malaysia, Dialog D&P and Petronas Carigali. The Balai Cluster comprises a group of marginal oil and gas fields in areas around the Balai and West Acis discoveries, located in water depths of 60m.

The new contract is a model that strikes a balance in sharing risks with fair returns for development and production of discovered marginal fields. Petronas will be the project owner while the contractors are the service providers.

A pre-development phase is scheduled to start shortly, taking up to 18 months, that includes geological and geophysical work, drilling and testing appraisal wells and the procurement of facilities and equipment at an estimated cost of $200-250 million.

Subsequently, the contractor group will submit a field development plan, with all the fields in the cluster planned to be online within 24 months at an approximate cost of $650 million. This second phase will include the drilling of wells, installation of platforms, topsides and pipelines, and tie-in of the new facilities to existing Petronas Carigali infrastructure as appropriate.

Petrofac has signed two memoranda of understanding with Petronas. The first concerns acceleration of production through a third phase of development of offshore block PM304, operated and 30% owned by Petrofac and inclusive of the Cendor and West Desaru fault blocks. Development of West Desaru will be sped up with an early production system that entails use of both current export facilities and upgrading and deployment of a MOPU, expected to bring forward first oil production to 4Q 2012.

The second outlines collaboration in competency development, capability building and education activities involving a technical training partnership between Petrofac Training Services and Institut Teknologi Petroleum Petronas.
