Flow test continued 17. May 2011 – but needed to be stopped few days later. Continued 9.August 2011 but stopped 11. August for further modification. Opened again 27th September 2011 for wet scrubbing and heat exchange test. From November 2011 to July 2012 flowing at 10-12 kg/sec
Superheated dry steam: 452°C, 140 bar, 3200 KJ/Kg – power output ~ 36 MWe Video clips at www.iddp.is

Sequence of events:
Thermally cracked the metamorphic contact aureole rocks by cold water drilling- and injection fluid Attracted 350°C two phase reservoir fluid from above – downwards - heating it up to 450°C Flowing the 450°C hot superheated steam - needing chemical mitigation for production By wet scrubbing Cl, S and SiO2 were driven into the fluid phase – leaving pure steam for power production CO2 proved to be lower than in atmosphere
Apparently IDDP created a magmatic EGS system

Reykjanes power plant: 100 MWe RN-15 production well: 2.5 km deep RN-15 defined as Well of opportunity for IDDP-2 It will be directionally drilled to 5 km depth in 2016 Flow tested in both directions – down and up Pilot tested for power production Scientifically studied as a black smoker analog Reservoir fluid is of seawater origin

Immediate tasks ahead:
Finalize design – 2 months Purchase all needed materials: Casings, wellhead valves, expansion spool, cement and drilling mud - 4 to 6 months Monitoring: add to existing surface monitoring equipment prior to drilling – 3 to 4 months Detailed Drilling Plan Detailed Stimulation Plan Detailed Testing plan DRILLING: June to October 2016

Preparation for the IDDP-2/DEEPEGS well at Reykjanes has been in progress since 2012 NEAR FUTURE VISION: Our expectation is that by DEEPEGS type drilling we will see more efficient power production from high- temperature geothermal systems worldwide
