25 March 2009, at 21:40 Jardboranir Ltd drill rig Tyr started drilling into rocks again, at a depth of 796.7 m, relative to Tyr’s platform (7.8 m above surface). The photo shows a view from the AD 1724 Víti explosive crater (since the Myvatn Fires), some 0.5 km across towards the drill rig. The Leirhnukur fumarole field is seen in the background as well as craters from the 1975-1984 eruptive fissure of the Krafla Fires, some 1.5 km west of the rig.

The “kickoff meeting” at the Orkugarður auditorium in Reykjavik was held two weeks before a rig is to be activated at the Krafla geothermal field in NE Iceland to resume drilling the IDDP-1 exploratory/research well. Drilling and casing to 800 m occurred in December 2008. Drilling to 4500m depth should take a further 115 days. The workshop reviewed the planning for drilling and testing this well, and integration of the drilling and activities on site, including downhole logging and experiments, and sampling of rocks and fluids, including coring. The more than 40 attendees were mostly members of the three advisory panels, Drilling Technology, Geosciences, and Fluid Handling and Evaluation, together with the downhole logging group (ISOR and HITI), Deep Vision (the steering committee), and SAGA (the advisory committee). The agenda and a list of attendees of the workshop are attached to this report. After a day of presentations by representatives of these groups, and a half day of discussions, a number of items were discussed that could require further review or action, that are listed in this report. Overall, however, the review of the comprehensive plans presented was very positive: there were no “show-stoppers” identified.

During the 25th of November 2008 a very successful spot coring test was performed at 2800 m depth in the production well RN-17 B at Reykjanes. Well RN-17 B was being reconditioned by side-tracking it out of well RN-17 at 930 m depth below the production casing, to become an inclined exploration/production well. The core test was performed in an open hole at 35° inclination with newly built coring equipment. The main benefit of the core barrel is its unique feature to enable much greater water flow-rates for cooling during coring, or up to 40 l/s, as compared to conventional core barrels with only 4-5 l/s flow rates. A 9.3 m hydrothermally altered hyaloclastite breccia was cored with so to speak 100% core recovery. The newly purchased ICDP core barrel and bits proved just perfect for our IDDP purpose of coring in high temperature wells, and only minor improvement on the equipment is needed before further spot coring in the IDDP-1 well in Krafla next summer. The core bit experienced some 280°C during coring, and the entire operation took some 33 hours rig time. A short report is attached.

According to our drilling schedule the drilling for 24 1/2″ casing to 280 m, and then for 18 5/8″ casing to 800 m depth, was supposed to occur this autumn. The drill rig Jötunn has been rigging up since last week and began drilling for the 24 ½” casing today. Weather conditions in Krafla are fine today and the rig will continue for the next 3 weeks or so before leaving for the Azores for the winter. The photo below was taken this afternoon by Hinrik Árni Bóasson.

The IDDP drilling plan can be viewed on a poster that was presented at the IGC-2008 congress in Oslo last summer.

Deep Vision, the steering committee of the Iceland Deep Drilling Project (IDDP) announces that the partners in the IDDP consortium, including a new partner, namely StatoilHydro ASA from Norway, have signed the 1st Accession Protocol to the existing contract to collaborate in deep drilling in Iceland. The consortium collaborating to test the IDDP concept now consists of the three leading Icelandic power companies, Hitaveita Sudurnesja Ltd., Landsvirkjun, Orkuveita Reykjavikur, together with Orkustofnun, Alcoa Inc. and the New Energy Division of StatoilHydro ASA.

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: http://www.isor.is/~gme/iddp-krafla/. 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.
