    摘要: A method and apparatus for applying hydraulic treatment and diversion treatment to a wellbore are described. The method involves isolating a wellbore segment using hydraulic seals; applying fluid treatment and perforation diverters within the isolated segment; and scraping a portion of the wellbore after termination of treatment to remove any lodged perforation diverters from the wellbore. A collection chamber may also be provided for collecting used diverters for return to surface following treatment. In one embodiment, diverters used and collected within a first segment may be reused during treatment of a successive wellbore segment.

    摘要: System, devices, and methods are described relating to the treatment (e.g., perforating, fracturing, foam stimulation, acid treatment, cement treatment, etc.) of well-bores (e.g., cased oil and/or gas wells). In at least one example, a method is provided for treatment of a region in a well, the method comprising: positioning, in a well-bore, a packer above the region of the well-bore, fixing, below the region, an expansion packer, treating the region, the treatment fixing the packer, moving the expansion packer, and moving the packer after the moving of the expansion packer.

    摘要: A well servicing rig for communicating with a fluid source and an effluent reservoir (such as a flow back tank) has an apparatus for holding and dispensing coiled tubing. A manifold assembly is advantageously located on the rig for routing the pressurized fluid (such as nitrogen gas mixed with proppant) from the fluid source between the coiled tubing apparatus, the well and the effluent reservoir. The manifold assembly controls the flow of the fluid to perform fracturing operations, for reverse fluid circulation, for a common coiled tubing operation, for pressure testing, and the like. The assembly includes remotely controlled valves and pressure transducers for controlling the fluid flow, and chokes for diffusing fluid energy prior to entering the effluent reservoir. The rig, fluid source, effluent reservoir and a fluid pumper provide a novel method of servicing an underground formation (such as a coal bed) for natural gas.
