Sub-basalt imaging - new insight from investigations of petrophysical and seismic properties of Faroes basalts (SeiFaBa project)
The development of methods of seismic imaging beneath basalt is still hindered by a lack of knowledge about the elastic properties of basaltic sequences and the degree of three-dimensional heterogeneity. The SeiFaBa project (2002- 2005) is funded by the Sindri Group as part of the programmes for lic...

The development of methods of seismic imaging beneath basalt is still hindered by a lack of knowledge about the elastic properties of basaltic sequences and the degree of three-dimensional heterogeneity. The SeiFaBa project (2002- 2005) is funded by the Sindri Group as part of the programmes for licensees within the Faroese area and will address these issues. The first year included drilling of a new 700-m deep well, Glyvursnes-1, near Tórshavn with full core, reaming of the existing 660 m deep Vestmanna-1 well farther north, and the acquisition of a wide range of wireline logs in both wells. The two wells represent almost half of the exposed lava sequence and are central to a number of co-ordinated experiments. These are targeted at creating firm data-derived models for seismic wave propagation through basalt by combining detailed analysis at core, log and seismic scales. After initial tests in 2002 the main part of the seismic programme was carried out June to September 2003.
