“…To this end an initial section of each 46" conductor would need to be run open-ended to seabed to act as a drilling assembly conduit prior to spud. Use of open-ended conductor in turn obviated simple use of internal conductor guides or landing rings (Tuah et al, 2000, Anchaboh et al, 2001Faget et al, 2005) into which subsequent 18-5/8" strings could be run. Dual 18-5/8" conduit strings would need to be installed unguided into open ended 46" conductor.…”

The Magnus platform, UK Northern North Sea, has been producing since 1983 with all 20 original slots now occupied. Additional infill and ERD production targets were identified and a means of access was required whilst maintaining base field production. Platform modification was selected due to significant commercial advantage over alternative developments.The Magnus jacket was modified to permit running of four additional large conductors into which two smaller casings could respectively be installed.Modification of existing wellhead technology for close proximity has proved successful. Access to additional Magnus resources via an otherwise full template has been delivered by this Conductor Sharing Wellhead (CSW) technology.
