  • Regional geological recognition for the implementation of a urban geothermal concept

    A reflection seismic survey was performed in the city of Lausanne (CH) to map geological layers relevant to geothermal energy production. By using a wireless seismic system and a powerful seismic vibrator source we were able to high quality results despite the presence of elevated urban noise levels. The new subsurface maps allow the estimation of the geothermal potential for the city of ...

  • The purpose of using drilling shale shaker in oilfield

    The purpose of using drilling shale shaker is to remove the large cuttings in drilling fluid. Each set of solids control system must be equipped with a sufficient number of shale shaker to ensue the 100% processing rate of drilling fluid circulation. Shale shaker is the first solids control equipment to process and adjust the drilling fluid, ...


  • Fossil Fuel Development in the Arctic is a Bad Investment

    Even master chess players can miss a great move when they have been primed to look for a different one. To explore this phenomenon, researchers tracked master chess players’ eye movements when given chessboards with different layouts. With the first board, players could reach checkmate using a familiar move. When given the second chessboard, the players' eyes kept looking at the pieces ...

  • Kenya’s first carbon credits from geothermal energy pay for schools

    Last month, I drove through dust on bumpy dirt roads from Nairobi to visit the Oloirowua Primary School in Suswa, 140 kilometers northeast of the Kenya capital. The school sits on the vast savannah near Hell’s Gate National Park, an area with substantial geothermal potential. Here, KenGen, Kenya’s electric generating company, has built the ...

  • 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 ...

  • Nevada Geothermal, Ormat to develop Oregon resource

    Nevada Geothermal Power Inc. (Vancouver, B.C.) and Ormat Nevada Inc., a subsidiary of Ormat Technologies Inc. (Reno, NV), have signed an agreement under which the two companies will jointly develop, construct, own, and operate one or more geothermal power plants at the Crump Geyser Project Area in Lake County, Oregon. The agreement calls for the formation of a limited liability company, ...

  • Modeling geothermal wells using SVHeat and SVFlux

    Numerical modeling of geothermal processes has received increased attention in recent years. The process of installing geothermal heating systems in residential homes and cottages is one application of numerical models. These systems typically involve drilling between one and three wells on a particular property. Heat exchangers then act as a pump and remove heat from the ground in order to heat ...

  • How important is green education in promoting green jobs?

    How important is green education in promoting green jobs? I doubt there is anything more important than education for those who have a curiosity of how the green economy can transform our current dilemma.Is it possible that what others are doing in other countries could work here in the United States? According to the European Energy Commission website , Energy is what drives the engine for ...


  • What’s geothermal again?

    Some green energy sources seem to have charisma; others struggle for public attention with little success. Solar energy is an “it” technology, as evidenced once again by the tremendous participation in the annual Solar Power International conference in Anaheim, California this week (Oct. 27-29). Twice as many companies (945) are displaying their wares in the Expo Hall this year, despite the still ...

  • Why the mud won`t stick anymore

    Certainly, the Increased demand on resources within the oil and gas Industry has led to significantly higher costs In many areas of operation, not least having the means to clean equipment, such as mud tank*, pffertivply. And in the process of cleaning the mud pits on the rigs and the cleaning ot Thp mud Tanks on platform supply vessels and barges, there is the added complication of tightened ...

  • A BME solution of the stochastic three-dimensional Laplace equation representing a geothermal field subject to site-specific information

    This work develops a model of the geothermal field in the Nea Kessani region (Greece) by means of the Bayesian maximum entropy (BME) method, which describes the temperature variations across space in the underground geological formations. The geothermal field is formed by a thermal reservoir consisting of arcosic sandstones. The temperature distribution vs depth was first investigated by the ...

  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...
