    摘要： A system for fracturing a formation comprising a laser surface unit configured to generate a laser beam, a power cable electrically connected to a power source, a fluid line connected to a cooling fluid source, a protective shaft extending into the wellbore, the motor configured to rotate a motor shaft, and the thermal shocking tool comprising a protective case, a rotational shaft connected to the motor shaft, the laser delivery device extending from the rotational shaft configured to transform the laser beam to a focused laser beam operable to increase the temperature of the formation to a fracture temperature, and the cooling system extending from the rotational shaft opposite the laser delivery device configured to introduce the cooling fluid stream onto the formation such that the cooling fluid stream reduces the temperature of the formation such that thermal shocks occur and fractures are formed in the formation.

    摘要： A hood assembly (42) is arranged to direct a vacuum air flow (266) that removes a volume of air containing proppant dust particles (264) after proppant (92) has been transported to a desired location via a flow path (268). The hood assembly (42) comprises a first hood section (154), a second hood section (156) and a third hood section (158). The first hood section (154) substantially surrounds and receives an outlet of a chute (24) that directs the proppant (92) to the desired location. The first hood section (154) comprises at least one dust receptacle (166) extending through a body of the first hood section (154) to enable the volume of air to exit the first hood section (154). The second hood section (156) is positioned adjacent the first hood section (154) and comprises at least one dust receptacle (174) to receive the volume of air. The third hood section (158) is positioned adjacent the first hood section (154) and opposite the second hood section (156). The third hood section (158) comprises at least one dust receptacle (182) to receive the volume of air and is substantially symmetrical to the second hood section (156) about the first hood section (154).

    摘要： The present invention provides a method and system for blending a fracturing fluid for delivery to a wellbore to be fractured. The method comprising the steps of providing: a turbine generator at a well site, wherein the turbine generator provides a source of electrical power; and at least one electric blender at the site, the electric blender comprising a blender tub that receives fluid from a fluid source (48) and a fluid additive source (44), wherein the electric blender receives electric power from the source of electric power to effect blending of a fluid from the fluid source (48) with a fluid additive from the fluid additive source (44) to generate the fracturing fluid.
