LONDON – The semisub Transocean Sedco 704 has spud the Tudor Rose 14/30a-5 well in the UK central North Sea.
EnCore Oil is operator of block 14/30a; Applied Drilling Technology International (ADTI) is managing the operation, which should take around 20 days.
The Tudor Rose oil accumulation was discovered in 1983 via well 14/30a-2, which encountered an 80-ft (24-m) oil column in Tertiary-age Beauly Sands.
The current well is being drilled 2.5 km (1.55 mi) from the discovery well, but at a similar elevation. One of the main aims is to establish the gravity and viscosity of the oil within the Beauly sands, at a depth of roughly 3,200 ft (975 m) TVDSS.
