Such equipment as casing, drillstrings, mud, logging, and rigs that were adequate to drill most of the North Sea wells to date will require modifications to drill the high-pressure, high-temperature (HPHT) formations in the Central Graben of the North Sea. HPHT exploration wells are slowly becoming part of the drilling scenario in the North Sea Central Graben. Predominantly drilled in the U.K., an increasing number are now planned for the Norwegian sector during 1991.
