The concept of the Iceland Deep Drilling project
Geothermics, 2014Co-Authors: Guðmundur Ómar Friðleifsson, Wilfred A. Elders, Ann-christine AlbertssonAbstract:Abstract Calculations discussed in the Iceland Deep Drilling Project feasibility study in 2003 indicated that, for same volumetric flow rate of steam, a geothermal well producing from natural supercritical fluid would have the potential to generate power outputs an order of magnitude greater than from conventional high-temperature wells (240–340 °C). To reach supercritical hydrous fluid conditions in natural geothermal systems requires Deep Drilling to a minimum depth of some 3.5–5 km were temperature conditions can be expected to range between 400 and 600 °C in reasonably active high-temperature fields. Three geothermal fields in Iceland, Reykjanes, Hengill and Krafla, were selected as suitable locations for Deep Drilling to test this concept in search of natural supercritical geothermal fluid systems.

Progress Report on the Iceland Deep Drilling Project
Scientific Drilling, 2007Co-Authors: Gudmundur O. Fridleifsson, Wilfred A. EldersAbstract:The Iceland Deep Drilling Project (IDDP) is a project of “Deep Vision”, a consortium of the government and the three leading energy companies in Iceland. It aims to improve the economics of geothermal energy production by exploring for supercritical hydrothermal fluids as a possible energy source. This will require Drilling to depths of 4 to 5 km in order to reach temperatures of 400°C–600°C. From the outset, Deep Vision, recognizing that a broad scale of studies would be necessary in order to explore the little understood supercritical environment, welcomed the inclusion of basic scientific studies in the IDDP and invited participation from the international scientific community, to the mutual advantage of both industrial and scientific participants (Fridleifsson and Albertsson, 2000)

The Newberry Deep Drilling Project (NDDP) workshop
Scientific Drilling, 2018Co-Authors: Alain Bonneville, Guðmundur Ómar Friðleifsson, Trenton T. Cladouhos, Susan Petty, Adam Schultz, Carsten Sørlie, Hiroshi Asanuma, Claude Jaupart, Giuseppe De NataleAbstract:Abstract. The important scientific questions that will form the basis of a full proposal to drill a Deep well to the ductile–brittle transition zone ( T>400 ∘C ) at Newberry Volcano, central Oregon state, USA, were discussed during an International Continental Drilling Program (ICDP) sponsored workshop held at the Oregon State University-Cascades campus in Bend, Oregon, from 10 to 13 September 2017. Newberry Volcano is one of the largest geothermal heat reservoirs in the USA and has been extensively studied for the last 40 years. The Newberry Deep Drilling Project (NDDP) will be located at an idle geothermal exploration well, NWG 46-16, drilled in 2008, 3500 m Deep and 340–374 ∘ C at bottom, which will be Deepened another 1000 to 1300 m to reach 500 ∘ C. The workshop concluded by setting ambitious goals for the NDDP: (1) test the enhanced geothermal system (EGS) above the critical point of water, (2) collect samples of rocks within the brittle–ductile transition, (3) investigate volcanic hazards, (4) study magmatic geomechanics, (5) calibrate geophysical imaging techniques, and (6) test technology for Drilling, well completion, and geophysical monitoring in a very high-temperature environment. Based on these recommendations, a full Drilling proposal was submitted in January 2018 to the ICDP for Deepening an existing well. The next steps will be to continue building a team with project, technology, and investment partners to make the NDDP a reality.

synthetic tracking using ztf Deep Drilling data sets
Publications of the Astronomical Society of the Pacific, 2020Co-Authors: Chengxing Zhai, Michael Shao, Russell Trahan, Janice Shen, Thomas A. Prince, Eric C. Bellm, Matthew J. Graham, George Helou, Navtej Saini, Shrinivas R. KulkarniAbstract:The Zwicky Transit Facility (ZTF) is a powerful time domain survey telescope with a large field of view of 47 deg². We apply the synthetic tracking technique to integrate a ZTF's Deep Drilling data set, which consists of 133 nominal 30 s exposure frames spanning about 1.5 hr, to search for slowly moving asteroids down to approximately 23rd magnitude. We found 1168 objects from searching 40 of the 64 CCD-quadrant subfields, each of which covers a field size of about 0.73 deg². While most of the objects are in the core region of the asteroid belt, there are asteroids belonging to families of Trojan, Hilda, Hungaria, Phocaea, and near-Earth-asteroids. Such an approach is effective and productive for discovering new asteroids. Here we report the data processing and results as well as discuss a potential Deep Drilling operation mode using this approach for survey facilities.

well design for the iceland Deep Drilling project iddp
Geothermics, 2014Co-Authors: Sverrir Thorhallsson, Bjarni Palsson, S Holmgeirsson, Kristinn Ingason, M Matthiasson, H A Boasson, H SverrissonAbstract:Abstract The aim of the Iceland Deep Drilling Projects (IDDP) was to drill to a depth of 4–5 km in known high-temperature areas to investigate their roots. The paper describes the design of the “generic” IDDP well and what the plans were. The challenges are to drill a large well with five cemented casing strings to 4500 m into a reservoir which can have a temperature of 400–600 °C. In 2009 well IDDP-1 was drilled according to these plans but could not reach below 2100 m due to the intersection of magma, as will be described in other papers in this special issue of Geothermics. The paper is thus for the historical record of the original design premises and intentions.

investigations related to scientific Deep Drilling to study reservoir triggered earthquakes at koyna india
International Journal of Earth Sciences, 2015Co-Authors: Harsh K. Gupta, Sukanta Roy, Kusumita Arora, Purnachandra N Rao, V M Tiwari, Prasanta K Patro, H V S Satyanarayana, D Shashidhar, K Mallika, Vyasulu V AkkirajuAbstract:Artificial water reservoir-triggered earthquakes have continued at Koyna in the Deccan Traps province, India, since the impoundment of the Shivaji Sagar reservoir in 1962. Existing models, to comprehend the genesis of triggered earthquakes, suffer from lack of observations in the near field. To investigate further, scientific Deep Drilling and setting up a fault zone observatory at depth of 5–7 km is planned in the Koyna area. Prior to undertaking Deep Drilling, an exploratory phase of investigations has been launched to constrain subsurface geology, structure and heat flow regime in the area that provide critical inputs for the design of the Deep borehole observatory. Two core boreholes drilled to depths of 1,522 and 1,196 m have penetrated the Deccan Traps and sampled the granitic basement in the region for the first time. Studies on cores provide new and direct information regarding the thickness of the Deccan Traps, the absence of infra-Trappean sediments and the nature of the underlying basement rocks. Temperatures estimated at a depth of 6 km in the area, made on the basis of heat flow and thermal properties data sets, do not exceed 150 °C. Low-elevation airborne gravity gradient and magnetic data sets covering 5,012 line km, together with high-quality magnetotelluric data at 100 stations, provide both regional information about the thickness of the Deccan Traps and the occurrence of localized density heterogeneities and anomalous conductive zones in the vicinity of the hypocentral zone. Acquisition of airborne LiDAR data to obtain a high-resolution topographic model of the region has been completed over an area of 1,064 km2 centred on the Koyna seismic zone. Seismometers have been deployed in the granitic basement inside two boreholes and are planned in another set of six boreholes to obtain accurate hypocentral locations and constrain the disposition of fault zones.

Probing reservoir-triggered earthquakes in Koyna, India, through scientific Deep Drilling
Scientific Drilling, 2014Co-Authors: Harsh K. Gupta, Shailesh Nayak, William L. Ellsworth, Y. J. B. Rao, S. Rajan, Brijesh K. Bansal, N. Purnachandra Rao, Sukanta Roy, Kusumita Arora, R. MohanAbstract:We report here the salient features of the recently concluded International Continental Scientific Drilling Program (ICDP) workshop in Koyna, India. This workshop was a sequel to the earlier held ICDP workshop in Hyderabad and Koyna in 2011. A total of 49 experts (37 from India and 12 from 8 other countries) spent 3 days reviewing the work carried out during the last 3 years based on the recommendations of the 2011 workshop and suggesting the future course of action, including detailed planning for a full Deep Drilling proposal in Koyna, India. It was unanimously concluded that Koyna is one of the best sites anywhere in the world to investigate genesis of triggered earthquakes from near-field observations. A broad framework of the activities for the next phase leading to Deep Drilling has been worked out.
