NEW IDDP CONTRACT SIGNED

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 www.isor.is/~gme/iddp/. 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.

TENDER DOCUMENTS

Date: November 10 – November 30, 2006

Iceland Deep Drilling Project announces: Pre-Qualification Documents KRA-46 for Drilling Works

Landsvirkjun, on behalf of IDDP, is seeking applications from drilling contractors for participation in negotiated procedure for tendering of Drilling Works according to Pre-Qualification Documents KRA-46, which are available at Landsvirkjun, Háaleitisbraut 68, 103 Reykjavík against the payment of IKR 3,000.-. http://www.lv.is/event.asp?catID=30&EventId=187

Applications shall be delivered to Landsvirkjun, Purchasing Department, Háaleitisbraut 68, 103 Reykjavík before 15:00 GMT, Thursday, December 7th 2006.

The project involves drilling and setting casings for a 3500 m deep high temperature well in the year 2008. For information on the likely geothermal conditions at the potential drill site at Krafla see: Krafla-IDDP-Review-Report-ISOR-2006-030.pdf

TENDER DOCUMENTS

Tender documents for wellhead valves and fittings (KRA-44 and KRA-45) were announced earlier this month.
See http://www.lv.is/EN/events.asp?catID=323

Tender documents for IDDP casings for a 3.5 km deep well will be made available at Landsvirkjun, September 19th, 2006. The tender documents are for two types of wells, i.e. for well design A, and for well design C. Bids will be opened at 14:00, November 1st, 2006.

Update on the IDDP

Earlier this year Deep Vision decided to move operations for the first IDDP deep drillhole to Krafla. Bid documents for the supply of casings and valves for the proposed well are just about being announced by Landsvirkjun, and well design is being finalized. We anticipate that the drilling will take place no later than early 2008. See IDDP_2006_update

SAGA Report No. 5

A decision is expected within few weeks where to drill the first IDDP well, be it at Krafla, Reykjanes or Hellisheidi. The 5th SAGA meeting was held in Reykjavik at the end of April 2006 to evaluate drilling options after well RN-17 at Reykjanes was lost earlier this year. The proceedings of the SAGA meeting and the ensuing meetings with DeepVision and representatives of ICDP and NSF are described in SAGA Report No. 5. At a DeepVision meeting yesterday it became clear that the evaluation process needs to continue for a few more weeks before a decision on the drillsite will be made.
