UK HPHT well survey identifies security gaps
From Offshore Magazine, by Jeremy Beckman, Editor, Europe Jul 26, 2006
Confidence is growing in managing hostile high-pressure, high-temperature reservoirs.
In the North Sea, rising gas prices are driving development of even the most problematic fields. Doubts remain, however, about the long-term integrity of well architecture.
In response, the UK Health & Safety Executive commissioned a study by consultants Highoose into HP/HT engineering challenges and security concerns, based mainly on experience in the UK North Sea from 1987 to 2003.
The recently published findings suggest that the drilling industry in this sector is generally on the right track, but more unknowns are also emerging as new techniques are put into practice.

HSE describes the UK
Outside the large producing gas-condensate fields in the Central North Sea, there have also been HP/HT discoveries (gas and oil) in the Outer Moray Firth, Viking Grabens, the Magnus Embayment, and West of Shetland.
Based on UK Department of Trade and Industry definitions, the authors identified 227 HP/HT wells drilled across the UK shelf between 1987 and 2003, with a peak of 30 well spuds in 1997.
A total of 130 safety incidents were reported from wells in this category up to the end of 2003.
