Mr. Skeet
asked the Secretary of State for Energy, of the total capital cost of developing leading oil fields in the North Sea, what percentage is allocated to production platforms, modules, gas separation units, and pipelines to shore terminals or mooring facilities.
Dr. John A. Cunningham
Disaggregation of total capital costs for North Sea oil field development into the detail requested is not possible. A number of different methods are used to produce and convey the oil. The following broad average figures, based on estimates from the operators, conceal wide variations between particular fields and therefore need to be treated with reserve:
| Platform structure | 30 per cent. |
| Platform equipment | 20 per cent. |
| Pipelines and single-point moorings | 20 per cent. |
| Terminals | 15 per cent. |
| Development drilling and miscellaneous | 15 per cent. |
