asked the Secretary of State for Energy what was the level of exports of products derived from North sea crude oil expressed as a percentage of North sea crude production in each year since 1979.

The United Kingdom refinery industry uses a mixture of North sea and other crude oils in refinery operations. Petroleum products are thus derived from a complex process of mixing, refining and blending, of which North sea crude oils are a major component. Total United Kingdom product exports by weight expressed as a percentage of total crude production since 1979 are as follows:

Product Exports as Percentage of United Kingdom Crude Oil Production

197917·4
198018·5
198114·5
198213·5
198313·2
198411·8

Note: These figures include a very small amount of United Kingdom non-North sea crude.

asked the Secretary of State for Energy what was the number of obligatory wells required as conditions in the allocation of licences in rounds 1 to 5; and what so far has been the number actually drilled.

The position, round by round, is:

Licensing RoundObligatory Wells (firm & conditional)Obligatory Wells Drilled
19892
24537
34937
4225174
55233
The period within which the obligatory wells have to be drilled has not yet been completed for all fifth round licences.

asked the Secretary of State for Energy what was the amount of North sea crude oil refined in Britain each year since 1980; and if he will express that amount as a percentage of North sea crude oil production.

The amounts of North sea crude oil refined in Britain since 1980 were as follows—all figures in million tonnes—
