Notes:

(1) Sidetracked wells are shown in brackets. Sidetrack wells are only counted where the intent was to acquire new geological data
(sidetracks drilled due to mechanical problems with the original well are not counted).
(2) The first figure is the total number of wells including the number of geological sidetracks. The actual number
of geological sidetracks included in the total is the second figure shown in brackets.
(3) 'West of Shetland' includes 'West of Scotland' and the Rockall basin.
(4) The figures for offshore activity are no longer collated by geographical area as has been done in past years. The tables and diagrams
from 1995 reflect the geological approach to grouping wells broadly by sedimentary basin area. The major areas of change are the outer
Moray Firth which is now partly included in the Northern North Sea rather than 'East of Scotland', and the Central North Sea which was previously
split between 'East of Scotland' and 'East of England': the figures for these areas are thus not directly comparable with previous years.
DTI database definitions of the Geological Basins are currently based on Quadrant/Block criteria.
(5) Central North Sea includes inner, most of the outer Moray Firth areas and part of the Mid North Sea High.
NB The year in which a well is drilled is determined by its start date.
