Challenge 2.
Drilling of a long reach water injector
• A new water injection well to the Beta ridge is being planned from the Gullfaks B
platform. Planning the well is ongoing.
• A good well project is often “drilled on the paper” before initiated offshore.
Describe a possible route from “drilling the well on paper”.
• The drilling industry has the last 5 years established remote expert team onshore.
• Describe how the Statoil should perform the expert team solution. Make a
recommendation about which measures Statoil need to take in order to be able to
drill these wells to Gullfaks Sør Statfjord.

Challenge 3a.
PLT in Gulltopp
• Gulltopp is a 10 km well drilled from Gullfaks A platform. The well had water
breakthrough after two years of production and it is now desirable to find out from
which zone the water is coming.
• Explain the PLT technology and how a Production logging tool (PLT) can improve
the oil recovery at Gulltopp.
• Plan a detailed PLT job for Gulltopp. (This includes simulations and detailed PLT
procedure)
• Make a cost estimate based on information from vendors, and show economics
before tax including Net Present Value.
• Statoil advisor: Knut Müller

WL operations bellow the rig on GF.
• The three Gullfaks platforms have two shafts with wells. Well operations and
drilling can then work independent. When production wells has to be shut in due
to barrier problems on the same shaft as drilling is doing their work, it would be
beneficial to secure this well properly without stopping drilling operation.
• Explain equipment for rigging up WL bellow the rig.
• What are the main issues for running WL bellow the rig?
• What are the financial benefits of running WL bellow the rig?
• Statoil advisor: Knut Müller.
