Activity Survey 2015
The complexity of the UKCS has grown dramatically over the last 50 years. Figure 28, showing oil production by field, illustrates that dynamic. In the UKCS’ early years, production was dominated by a small number of large fields. Now, in 2015, production is made up of hundreds of fields, typically much smaller in size. There is far greater inter-dependency between these fields and there is a need to consider joint developments or subsea tieback solutions as smaller fields often mean standalone development is not commercially attractive. This does make UKCS production vulnerable to a ‘knock-on effect’ if important pieces of infrastructure are shut-in, particularly if that shut-in is unplanned. The Production Efficiency Task Force, set up as part of the government-industry forum PILOT, is working to ensure that operators co-ordinate planned shutdowns so that they are carried out as efficiently as possible.
