  • Design of method and mechanism for geothermal energy extraction

    By drilling using a specially designed hydride carbide (melting point: 1,365°C) drill, we can drill the earth's crust to about 5 to 40 km to reach temperatures of 700 to 1,000°C, with minimum cost of the drill and drilling technology. Further, we can extract energy by pouring in water on an inserted carbide alloy vessel into the drilled well and bringing out as steam to drive the turbines. By ...

  • Drilling: Then & Now

    In a recent conversation with a colleague, we discussed the then and now of drilling. Reflecting back to 1988, it was jarring to realize that we have entry-level Geologists & Engineers today that were born that year! They won’t ever truly know what it was like then, and how far the drilling industry has come. They would be amazed at the lives, limbs, and hearing lost over past decades, ...

  • Geodrilling International - Installation of Closed-loop Borehole Probes

    The installation of closed-loop borehole probes is a challenge on almost any project. With many domestic clients requiring a large meterage of borehole to be installed in a small site, Nicholls Boreholes has found that the traditional manual installation of closed-loop borehole probes is no longer a safe or acceptable option. The company has developed the Loop Feeder, a hydraulically-driven, ...

  • Hydrogeological and environmental impact assessment of a geothermal closed loop ground source energy installation

    ESI in Milan was approached to give support for designing one of the largest closed loop systems for heating and cooling in Europe.  The system was installed at the IKEA store in Corsico, Milan, with the need to provide some 1.4 MWth and covering thermal energy demand in the range from 40 to 100%.  The closed loop system is expected to save the Client over 500 t/y in CO2 ...

  • IF Technology - Netherlands based Sun Solutions deploys eSight with SharePoint integration for management of geothermal energy systems at IF Technology

    IF Technology is Europe’s foremost specialist on geothermal energy systems. In the Netherlands over a thousand systems are in place where heat from the summer and cold from the winter is stored underground to be used again six months later. Needless to say, making use of nature’s own heating and cooling equipment makes for a very energy efficient way to get a comfortable temperature ...

  • Artificial geothermal energy potential of steam-flooded heavy oil reservoirs

    This paper explores the concept of harnessing geothermal energy from heavy oil fields that have undergone steam flooding and so accumulated substantial heat from steam injection. Once the steam flooding process reaches economic cut-off resulting from high water cut and/or high steam-to-oil ratio, the reservoir would be abandoned, leaving behind stored energy in the form of heat. From this point, ...
