OneSubsea, a Schlumberger company, has been awarded an engineering, procurement and construction (EPC) contract from Woodside Energy, for services to be performed offshore northwest Australia.

Under the agreement, OneSubsea will supply Woodside with a subsea production system and a dual multiphase boosting system for the Greater Enfield project.

“Greater Enfield is a demonstration of our phased and sustainable approach to growth”, Woodside CEO Peter Coleman, said when the project was approved, in late June.

The scope of the contract includes six horizontal SpoolTree subsea trees, as well as six horizontal trees for the water injection system and six multiphase metres.

As well as this, it includes a high-boost dual pump station with high-voltage motors, an umbilical, topside and subsea controls and distribution.

Additional, it entails the supply of intervention and work over control systems, landing string, and installation and commissioning services, the company informed in a statement.

The award follows Woodside Energy and Mitsui E&P’s approval of a total spending of US$1.9 billion (£1.41 billion) in the development of the Greater Enfield reserves.

Greater Enfield Costs Reduced With Tieback

The project, which includes the development of the Laverda Canyon, Norton over Laverda and Cimatti oil accumulations, is targeting 2P reserves of 69 million barrels of oil equivalent (boe).

The Greater Enfield development is expected to involve six subsea production wells and six water injection wells, with production being made through a 19.2 mile subsea tieback to the existing Ngujima-Yin FPSO facility in the Vincent field.

The use of this tie-back is expected to result in expense cuts for the project and first oil is expected in mid-2019.

“We have achieved investment spend at the low end of our guidance range by leveraging the latest technologies and using existing FPSO infrastructure”, Coleman said at the time.

“This allows us to accelerate the development of previously stranded resources,” he added.
