Well Slot is a monthly feature where Westwood’s Stephen Coomber looks at drilling activity and rig moves in UK and Norwegian waters.
UK Offshore Well Slot June 2024
As of 21 June, Westwood Global Energy reports that there are no exploration or appraisal wells active on the UKCS.
Only one well has completed during 2024, with the 21/3d-9, Z, Y Leverett appraisal well which spudded in 2023.
No well programmes have spudded in 2024 to date and no wells are expected to spud until July when the Shell-operated 48/8b Selene well is due to start operations as well as the Harbour-operated Joselyn South well which will be drilled from the Judy field template.
These will be followed by the Shell-operated Pensacola appraisal well.
A total of five exploration and three appraisal wells have the potential of spudding this year, although many may be delayed or not complete by year end.
Although the number of wells expected to be drilled is only slightly lower than the nine exploration and four appraisals completed in 2023, the timings of the wells are all in the second half of the year.
