This paper describes the results obtained, as well as the equipment and techniques used on the Jade Field in the UK Central North Sea to provide the perforation and completion operations of two new high-pressure/high-temperature (HP/HT) production wells.

This paper begins by discussing the types of equipment that are required for HP/HT coiled-tubing (CT) intervention. The completion design and methodology of these two wells will be discussed. The CT interventions and different perforating operations will then be presented for these wells. The paper outlines the specific types of downhole equipment that were needed for these operations. This includes, for example perforating gun hangers and detachable perforating connectors. This paper includes the application of new equipment designs and novel solutions to both surface and downhole constraints.

Lessons learned from each case history will be presented and conclusions will be drawn.
