Blane and Enoch are now expected to be developed for gross costs of about £165 million (A$391m) and £75m (A$178m) respectively.
“Production from both fields is scheduled to start in late 2006 at gross rates of 14,000 barrels of oil per day for Blane and 12,000bopd for Enoch,” Roc said.
Blane will be developed by three subsea wells, drilled in UKCS Block 30/3a, two of which will produce oil and associated gas, while one will be a water injector.
The wells will be serviced by new subsea infrastructure connected to the BP operated Ula Platform located 34 kilometres north-east of Blane in Norwegian Block 7/12.
A Blane reception module will be installed on the Ula facility to separate and meter the Blane produced fluids. Ula will also provide a full processing service to Blane, including provision of water for injection and high-pressure gas to accelerate and increase oil recovery.
Enoch will be developed by a single subsea well, drilled in UKCS Block 16/13a, which will produce oil and gas. The well will be tied back using new subsea infrastructure to the Marathon operated Brae A Platform located 15km North-West of Enoch in UKCS Block 16/7.
Modifications will be carried out on Brae A to support the subsea infrastructure and process and meter the Enoch produced fluids. The Enoch oil will then be exported from Brae A through the Forties Pipeline System and sold at Kinneil, while Enoch gas will be sold offshore to Brae.
The operator of both fields is Paladin Expro Ltd, which is also a partner with Woodside in the Laminaria/Corallina development in the Timor Sea.
The Blane and Enoch fields are two of the nine fields that Roc currently has at various stages of appraisal, pre-development and development – other fields under development included the Chinguetti and Cliff Head oil fields, chief executive John Doran said.
“With first production from Blane and Enoch scheduled for late 2006, six to nine months after first production from Chinguetti and Cliff Head, Roc’s 2006 production will receive a timely boost in the latter part of next year,” he said.
“This timing allows Roc to fund its share of the cost of developing the Blane and Enoch fields from internal sources without seeking fresh capital from shareholders, although the company will also consider financing these developments via a corporate or project loan facility.”
The Norwegian Government has ascribed proved and probable (2P) reserves of 32 million and 15m barrels of oil equivalent respectively to Blane and Enoch. This equates to a total net ROC 2P reserves for both fields of 5.8m barrels, slightly more than Roc's net share of current 2P estimates for the Cliff Head Oil Field, Doran said.
