A stratigraphic well through basalt
It is recommended to perform a feasibility study and evaluation of the possible benefits of a stratigraphic well through the basalt area in the Vøring and /or Møre Basin to gather data, promote research and stimulate exploration activity. The western offshore areas of Mid-Norway are covered by basalt rocks. The physical nature of these rocks means that it is almost impossible produce seismic images of the sediments that lie beneath them. This has blocked oil exploration drilling in these basalt areas as there has so far been no possibility to identify oil bearing strata. However, it seems likely that a similar oil province to Haltenbanken could lie beneath these basalts. The (se) research well(s) could be used as natural laboratories being studied by academia and industry in a joined effort. Close cooperation between institutes would provide a stimulating environment for advanced research within G&G fields lacking muscle, e.g. stratigraphy. A wealth of information pertaining to rock physics, sedimentology, heat flow etc could be gathered.

NGU/EMGSFeasibility study of integrated electromagnetic, gravimetric,
aeromagnetic and seismic sub-basalt exploration techniques
Objectives
• Construct a model of sub-basalt structures on the Møre Margin from potential field, seismic and well log data
• Attribute electric resistivity data to the model
• Simulate the electromagnetic response for the given geometry over the most likely 3D geo-model.
• Assess the feasibility of EM methods (Sea Bed Logging [SBL] and Marine Magneto-Tellurics [MMT]) for the sub-basalt imaging.
• Select optimal frequencies and transmitter waveform for a following acquisition if the metod is applicable.
