The use of a cooled fluid flow may enhance the performance of the pulsed-electric drilling process.

  • Patent number: 8312938
    Abstract: A method and device for installing a tube of a geothermal closed loop system in the ground. A drill rod includes a hook for removably mounting the heat exchange tube for positioning the tube in the hole bored in the ground by the drill bit. The tube may be inserted into the bored hole once the drill is removed therefrom, mounted to the tube and then reinserted into the hole. Alternatively, the tube is mounted to the drill rod as the hole is being bored.

  • Patent number: 8225882
    Abstract: A device for boring holes in rock mass working in a system, in which the reference axis is the axis of gravity, with thermal, pressure and sound energy comprises an assembly of at least one cone-shaped disintegrator body having an inner feed space. The front of the body houses nozzles followed by pressure sensors and has drainage flow lines distributed at its sides and leading into the surrounding space. The assembly further includes a cooperating hollow geometrical penetrator body. A forced movement of at least one disintegrator body occurs within the inner space of the penetrator body. The penetrator body has a broader front part, the cavity of which houses combustion chambers as well as signal and power media feed controlling components and has relaxation flow lines distributed at its sides. The middle part houses technical assemblies separating the working space at the front from the feed space.

  • Patent number: 8122950
    Abstract: Wellbore strengthening during drilling may be achieved by including chemicals in the drilling fluid that can be polymerised when exposed to microwave energy. Selected chemicals are mixed with the drilling fluid but do not react with it. The chemicals concentrate in a filter cake on the borehole wall during drilling-fluid circulation. A tool, which comprises a microwave source, is used to trigger polymerisation or crosslinking reactions within the filter cake. The polymerisation or crosslinking reactions cause the formation of a film or gel that strengthens the wellbore.

  • Patent number: 8100195
    Abstract: Example motor cooling radiators for use in downhole environments are disclosed. A disclosed example radiator comprises a cylindrical housing having an annular passageway. The housing defines an inlet at a first end of the housing and an outlet at a second opposite end of the housing. A channel is arranged within the annular passageway of the housing along a spiral path to transport the first liquid and to define a spiral flow passageway between the inlet and the outlet for the second liquid. In operation, the first liquid does not contact the second liquid and heat is transferred between the first and second liquids as the second liquid flows in the spiral passageway.

  • Patent number: 8082105
    Abstract: Disclosed is a method and apparatus for measuring in-situ stress in rock using a thermal crack. The method involves forming a borehole, cooling a wall of the borehole, applying tensile thermal stress, forming a crack in the borehole wall, and measuring temperature and cracking point. Afterwards, the borehole wall is heated to close the formed crack, the borehole wall is cooled again to re-open the crack, and temperature is measured when the crack is re-opened. The in-situ stress of the rock is calculated using a first cracking temperature at which the crack is formed and a second cracking temperature at which the crack is re-opened. Further, the apparatus cools, heats and re-cools the borehole wall, thereby measuring the first cracking temperature, the second cracking temperature, and the cracking point.
