Abstract: A system for treating a subsurface hydrocarbon containing formation includes one or more tunnels having an average diameter of at least 1 m. At least one tunnel is connected to the surface. Two or more wellbores extend from at least one of the tunnels into at least a portion of the subsurface hydrocarbon containing formation. At least two of the wellbores contain elongated heat sources configured to heat at least a portion of the subsurface hydrocarbon containing formation such that at least some hydrocarbons are mobilized.

Abstract: A system for treating a subsurface hydrocarbon containing formation includes one or more substantially horizontal or inclined tunnels extending from at least one shaft. One or more heater sources are located in one or more heater wellbores coupled to at least one of the substantially horizontal or inclined tunnels.

Abstract: A system for treating a subsurface hydrocarbon containing formation includes one or more substantially horizontal or inclined tunnels extending from one or more shafts. A production system is located in at least one of the tunnels. The production system is configured to produce fluids from the formation that collect in the tunnel.

Abstract: A method includes making coiled tubing at a coiled tubing manufacturing unit coupled to a coiled tubing transportation system. One or more coiled tubing reels are transported from the coiled tubing manufacturing unit to one or more moveable well drilling systems using the coiled tubing transportation system. The coiled tubing transportation system runs from the tubing manufacturing unit to one or more movable well drilling systems, and then back to the coiled tubing manufacturing unit.

Abstract: Methods and systems for controlling an ultrasound system are provided. The method includes receiving scanning information from an ultrasound system, with the scanning information including at least one of image information and spectral information. The method further includes controlling power to a transducer of the ultrasound system based on the scanning information.

Abstract: A dielectric welding apparatus for welding a plastic sleeve contains a solid state radio frequency generator linked via a matching network to a welding tool. The tool (30) includes a frame (35) with a handle (36), the frame defining a slot in which are opposed welding electrodes (40, 44), the slot being open at one end and at the other end communicating with a wider aperture (39). A pneumatic cylinder (48) can be actuated to urge the electrodes together, both the cylinder (48) and the RF generator (66) being activated by a trigger (50) on the tool (30). The electrodes are coated with an electrically insulating material that is not dielectrically heated, and are readily removable, so they can be replaced, for example when the electrically insulating coating becomes worn.

Abstract: Synthetic Rutile is prepared from raw ilmenite ore by a method comprising activating ilmenite and subjecting it to a multi-stage countercurrent leaching process in hot hydrochloric acid.
