    摘要： Methods for setting particulate plugs in at least partially horizontal sections of well bores are disclosed. In one embodiment, a method comprises the step of selecting a deposition location for a particulate plug within the at least partially horizontal section of the well bore. The method further comprises the step of providing a pumping conduit capable of delivering slurries to the deposition location. The method further comprises the step of pumping a first slurry through the pumping conduit to the deposition location such that a velocity of the first slurry in the well bore at the deposition location is less than or equal to the critical velocity of the first slurry in the well bore at the deposition location.

    摘要： A well bore in a subterranean formation includes a signaling subsystem communicably coupled to injection tools installed in the well bore. Each injection tool controls a flow of fluid into an interval of the formation based on a state of the injection tool. Stresses in the subterranean formation are altered by creating fractures in the formation. Control signals are sent from the well bore surface through the signaling subsystem to the injection tools to modify the states of one or more of the injection tools. Fluid is injected into the stress-altered subterranean formation through the injection tools to create a fracture network in the subterranean formation. In some implementations, the state of each injection tool can be selectively and repeatedly manipulated based on signals transmitted from the well bore surface. In some implementations, stresses are modified and/or the fracture network is created along a substantial portion and/or the entire length of a horizontal well bore.

    摘要： Methods and devices are provided for treating multiple interval well bores. More particularly, an isolation assembly may be used to allow for zonal isolation to allow treatment of selected productive or previously producing intervals in multiple interval well bores. One example of a method for treating a multiple interval well bore includes the steps of: providing an isolation assembly comprising a liner and a plurality of swellable packers wherein the plurality of swellable packers are disposed around the liner at selected spacings; introducing the isolation assembly into the well bore; allowing at least one of the plurality of swellable packers to swell so as to provide zonal isolation of at least one of a plurality of selected intervals; establishing fluidic connectivity to the at least one of a plurality of selected intervals; and treating the at least one of a plurality of selected intervals.

    摘要： Apparatuses and methods for improving the reliability of pinpoint stimulation operations is disclosed. A pinpoint stimulation improvement apparatus is disclosed which includes a hold down device, at least one flow reducer coupled to the hold down device, and a jetting tool coupled to the flow reducer. The flow reducer is positioned downstream from the jetting tool. A fluid flowing through the jetting tool passes through the flow reducer and forms a sand plug downstream from the pinpoint stimulation improvement apparatus.
