IDDP drillsite at Krafla

A final decision on the the first IDDP drill site in Krafla will be reached this month. Several potential locations are being considered and compared. A 3D video clip showing 6 potential locations of 5 km deep wells, as compared to a MT low resistivity surface and three volcanic fissure planes, shown as vertical planes and dipping 85° westwards: Permeability at depths is expected to be higher at the North an NW side of the heat source, but climatic conditions for winter drilling is less favourable on the N side.

An IDDP press release – in Icelandic and in English – was announced today.

Drilling of the first deep IDDP hole will take place in the Krafla high-temperature hydrothermal system in NE-Iceland late next year. Drilling of the 2nd IDDP well and the 3d IDDP well are planned for 2009 and 2010 – within the at Hengill- and the Reykjanes high-temperature hydrothermal systems in SW-Iceland, to some extent depending on the result of the 1st IDDP well.

Three deep wells of opportunity for will be drilled, one at each drillsite, Krafla, Hengill and Reykjanes. The potential sites are shown in 3D at A new poster on the IDDP status April 2007, will be presented at ENGINE Workshop 2 in Volterra, Italy, 1-4 April 2007.


SAGA Report No.6

IDDP Workshop 5 was held in Reykjavik 7-8 March 2007. In an opening address, Dr. Þorkell Helgason, Director General of Orkustofnun (the National Energy Authority), informed the participants, on behalf of the Icelandic Energy Consortium, that in the next few years, deep (> 3.5 km) exploratory boreholes are likely to be drilled in each of the three major geothermal fields in Iceland, namely the Krafla-, the Reykjanes-, and the Hengill field. Þorkell concluded by assuring the workshop participants that the IDDP now seemed to be „healthier“ than ever before. The purpose of Workshop 5 was twofold, firstly to discuss technical issues on drillcoring options and strategy in drilling into supercritical regime below 3.5 km depth, and secondly, to discuss and review the Feasibility Report (2003) plan on flow testing and sampling of supercritical fluids after drilling. The proceeding of the workshop and reccomendations by the Science Application Group of Advisors is described in SAGA Report 6. SAGA’s unanimous recommendation is that obtaining drill cores, especially in the transition from subcritical to supercritical and in the supercritical regime, remains an essential requirement for characterizing the deep reservoir. One major cost saving issue concerning flow testing after drilling, would be to simplify the fluid sampling and handling program that was recommended in the Feasibility Report (2003), by abandoning the system referred to as “The Pipe”, and replace it with a less technically challenging sampling system.
