    2011-11-08· Two major North Sea blowouts in 1988 led to significant changes in UK legislation, as well as international practices. All blowouts have different but equally significant consequences, and the September 1988 blowout in the Central Graben of the UK’s North Sea led to the establishment of an official definition of HPHT wells and to the development of HPHT codes and practices.

    HPHT Wells Standards Standards Drilling

    DefinitionGeneralPlanningEquipmentHPHT Well TestingMiscellaneousThere are different definitions of what comprises an HP/HT well: one of the most common used by major operators is linked to the expected shut in pressure and/or the expected reservoir temperature: 1. The expected shut in pressure must be higher than 690bar (10,000psi). 2. The expected well temperature must be higher than 150 OC (±300OF).The NPD in Norway add to this definition a concept of depth where wells deeper than 4000m (>13,100ft) should be considered as HP/HT, which is not the case in...

    Jade North Sea HPHT Development: Innovative Well Design

    The UK North Sea Jade Phase I development project demonstrates that high rate HPHT wells can be consistently drilled and completed within a £18.5mm well cost. Compared to other North Sea HPHT developments Jade is unique in providing the first experience of simultaneous drilling and production, with proven depletion levels up to 1600-psi, and
