A Special Issue of Geothermics, volume 49, January 2014, is devoted to IDDP. Fifteen articles, mostly devoted to well IDDP-1 in Krafla are published. The cover page can be opened here and the articles are all open at Science Direct.
Additionally, all articles in a sequence from 1-15 can be approached here.
A workshop report was published in the November issue of Scientific Drilling 2013 – see http://www.sci-dril.net/16/73/2013/sd-16-73-2013.pdf
Report on the IDDP-ICDP Workshop 3-5, September: SAGA Report 2012.
IDDP announces an ICDP supported workshop 3-5. September, 2012, in relation to a proposed drilling of a 5 km deep well, IDDP-2, into the Reykjanes geothermal system in SW-Iceland. Applications should be sent direct to Gudmundur O. Fridleifsson (email@example.com), with cc to W. A. Elders (Wilfred.firstname.lastname@example.org) and G. Bignal (email@example.com).

Flow tests of well IDDP-1 have continued this summer. After the flow tests in the summer of 2010 stopped, improvements were made to the wellhead and flowline to meet the demanding conditions. Below are a few video clips of the 4th flow test, August 9-10, 2011.
- Video clip: The test began by opening a 4” valve into a separate flow line. This lasted for about 10 minutes.
- Video clip: This video clip shows the flow condition ca. 3 minutes after the 12” operating valve had been fully opened into the 500 mm flow line and the rock muffler. The steam turned black after ca. 1 min. flow due to Fe-O-S-compounds from corroded liner.
- Video clip: After ca. 10 min. flow on the main flow line the steam turned white again and became superheated ca. 25-30 min from the beginning of flow test 4.
- Video clip: This video clip shows the transparent superheated steam flow ca. 12 h after opening. T: 410°C, P: 40 bar, H: 3150 KJ/Kg, Power output potentially 30-40 MWe. The well was closed 11. August for modification on the flow line. Wet scrubbing pilot test will begin about mid-September 2011.
The flow test of IDDP-1 began in March 2010, when the well was initially discharged. The initial flow test (phase 1) took place during 22-31 March 2010, when the well discharged through a DN100 (4’’) pipeline. The full-initial flow test (phase 1b) began 11 May, by discharging the well through a DN250 (10’’) pipeline with a 125 mm orifice. Initially the flow was wet but it has been superheated since May 18. This test is ongoing.
IDDP was presented by 15 papers at the World Geothermal Congress in Indonesia 25-30 April 2010. Three papers on drilling technology were presented at technical sessions 4A, 5A and 6A, and the remaining papers were presented at special IDDP session 18J and 19J – see link at:
