Drilling resurgent off UK, Norway
Exploration and appraisal well numbers across the UK shelf rose by 86% in the second quarter of 2010 compared with the same period in 2009, according to Deloitte’s latest survey.
ABERDEEN, UK -- Exploration and appraisal well numbers across the UK shelf rose by 86% in the second quarter of 2010 compared with the same period in 2009, according to Deloitte’s latest survey.
During this period, 28 E&A wells were spudded, 14 in both categories.
The highest activity was in the southern gas basin, accounting for 38% of all E&A wells in 2Q 2010. Elsewhere, one well spudded in the West Shetland basin, with six and eight wells in the Northern North Sea and Central North Sea respectively.
Also during the quarter, 13 wells were completed, of which seven encountered oil and one gas. Results from the other wells were either unknown or “tight” holes.
Activity was buoyant also offshore Norway, where Deloitte identified 19 E&A well spuds in 2Q 2010, up 58% compared with 1Q 2010. However, Deloitte does not see drilling activity in the Norwegian sector keeping pace with the record levels of 2009.
Of the second-quarter E&A wells, 68% were drilled in the Norwegian North Sea, the remainder further north in the Norwegian Sea.
Nine Norwegian wells were completed during the period, of which seven encountered hydrocarbons. Another was a dry hole.
Across the Dutch sector of the Southern North Sea, there were six E&A well spuds during 2Q 2010, an increase of 66% over the same period in 2009. Five were for exploration.
