    Abstract: A junk crusher device for crushing junk in a fluid stream includes a circular plate and a shaft. The circular plate includes fluid stream discharge holes and a bearing. The shaft is disposed within the bearing and includes detachably connected tear blades that are configured to rotate with the shaft. The junk crusher device further includes an impeller, hydraulically driven by the fluid stream, configured to rotate the shaft, an internal housing including fixed blades, and a body configured to receive the internal housing such that the internal housing is secured to an interior of the body. The rotating tear blades and fixed blades are configured to crush junk in the fluid stream. The fluid stream discharge holes disposed in the circular plate are configured to filter crushed junk.

    Abstract: A system for producing fluids from a wellbore extending from a well surface to a fluid-producing formation has a Y-tool installed in fluid communication with the tubing string placed in the wellbore. A pump, which may be an electric submersible pump (ESP), is installed in the Y-tool for lifting fluids from the formation to the surface. A blanking plug is positioned in the tubing string between the upper and lower connections of the Y-tool. A flushing port extends through a wall of the tubing string, positioned above and near the upper end of the blanking plug when in its operating position, and a flushing tube is located in the annular space between the tubing string and the wellbore casing. The flushing tube is in fluid communication with the flushing port and extends from the flushing port to the well surface. Flushing fluid is pumped downhole through the flushing tube to agitate and disperse any accumulated sand, scale and other particulate matter on top of the blanking plug.

    Abstract: A resource collection device of a resource collection system has a resource collection pipe, a protection pipe, and a coiled tubing device. The protection pipe is disposed around the resource collection pipe and protects the resource collection pipe. The coiled tubing device is fed from a winding reel disposed on the sea surface or inside the protection pipe by way of a feeding device and penetrates a side wall of the protection pipe to extend from the interior to the exterior. The resource collection system cracks the sea floor layer by way of: supplying undiluted solutions of foaming material, fuel gas, and air containing oxygen into the sea floor layer through the coiled tubing device; mixing the undiluted solutions of foaming material together to expand in an atmosphere that includes fuel gas and air; and causing the fuel gas accumulated in the hollows of the foaming material to explosively combust.

    Abstract: A perf and wash system for plugging a casing and wellbore, the perf and wash system including a cleaning tool having at least one nozzle making a first angle with a longitudinal axis of the system; a perforating gun assembly having at least one shaped charge making a second angle with the longitudinal axis; and a plug connected with a first end to the cleaning tool and with a second end, opposite to the first end, to the perforating gun assembly. The first angle is substantially equal to the second angle and the first and second angles are different than 90 degrees.

    Abstract: A method for plugging a subterranean well (6), comprising running a perforating tool (1) into the subterranean well and positioning the perforating tool in a well section (L) to be plugged; operating the perforating tool to create a plurality of holes (10) in a part (5) of a casing (4) located in the well section; running a surge tool (2) into the well; operating the surge tool (2) to lower the pressure inside the part (5) of the casing (4) located in the well section (L) and flowing a well fluid from an annulus (11) between the casing (4) and a well formation (7) through the holes (10); and pumping a fluidized plugging material into the well section (L) via a tubing string (9).
