  • Publication number: 20210348804
    Abstract: An embodiment in accordance with the present invention includes an EGS configured to allow the commercial production of electrical energy. One criteria of an EGS according to the present invention is that the temperature and volume of the fluids extracted are sufficiently high and large enough as to allow the commercial production of electrical energy. The system is able to operate for at least N years before the extracted fluid falls below the minimum temperature needed for energy production. Additionally, fractures are separated from each other by a sufficiently large volume of rock (Vcrit) relative to the fractures surface area such that the ratio of the rate of heat extraction to the rate of heat supply controlled by the thermal conductivity of the rock is such that the intervening rock is cooled at a rate that is sufficiently slow to be economic.

  • Patent number: 11098565
    Abstract: An embodiment in accordance with the present invention includes a method for estimating the permeability of fractured rock formations from the analysis of a slow fluid pressure wave, which is generated by pressurization of a borehole. Wave propagation in the rock is recorded with TFI™. Poroelastic theory is used to estimate the permeability from the measured wave speed. The present invention offers the opportunity of measuring the reservoir-scale permeability of fractured rock, because the method relies on imaging a wave, which propagates through a large rock volume, on the order of kilometers in size. Traditional methods yield permeability for much smaller rock volumes: well logging tools only measure permeability in the vicinity of a borehole. Pressure transient testing accesses larger rock volumes; however, these volumes are much smaller than for the proposed method, particularly in low-permeability rock formations.

  • Patent number: 8033745
    Abstract: A digital printer includes a digital printing unit for digital printing an image onto a printing substrate during relative movement between a print head and the printing substrate, and a printing table for holding the printing substrate during the digital printing. The printing table is firmly fixed to the digital printing unit during the digital printing of the image onto the printing substrate and is released from the digital printing unit prior to and after the digital printing of the image onto the printing substrate. The printing table may be moved between a printing position, in which it is firmly fixed to the digital printing unit, and a printing substrate feeding position, in which it supports feeding and removing of the printing substrate from the printing table.

  • Patent number: 7827910
    Abstract: A method of conveying imprint material and a printing table for a flatbed printing machine are described. The method of conveying imprint material, particularly solar cell wafers, in and out of a processing area of a flatbed printing machine includes the steps of moving the imprint material by means of a conveyor belt on a first conveyor belt section into the processing area, processing the imprint material and further moving the imprint material on the first conveyor belt section out of the processing area. An automatic checking of the first conveyor belt section for soiling or damage takes place and, as a function of the checking result, a moving-back of the first conveyor belt section into the processing area or a moving of a second conveyor belt section into the processing area takes place.

  • Patent number: 7802935
    Abstract: A printing table for a flatbed printing machine, for example, a large format digital flatbed printing machine, has a printing table base and a printing table plate disposed on the printing table base. The printing table base is connected by several connecting elements to the printing table plate. The connecting elements permit movement of the printing table plate relative to the printing table base, in particular movement caused by thermal expansion, only in a direction parallel to the printing table surface and only proceeding from a certain area of the printing table plate, the area having a point or line form and being fixed relative to the printing table base.
