IDDP – Drilling into magma

Stórmerkilegur árangur af fyrstu djúpborunarholunni í Kröflu. Icelandic.
World‘s first Magma-EGS system created. English.


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.


Workshop Report

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 (gof@hs.is), with cc to W. A. Elders (Wilfred.elders@ucr.edu) and G. Bignal (g.bignall@gns.cri.nz).

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.

  1. Video clip: The test began by opening a 4” valve into a separate flow line. This lasted for about 10 minutes.
  2. 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.
  3. 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.
  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.

IDDP-1 flow test.

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.
