A system includes production tubing installed in the well and a female component connected to the production tubing comprising a female component body located in a housing, primary coils wound through the female component body, and a borehole delineated by an inner circumferential surface of the female component body and having a borehole axis. The borehole outlines a shape. The system also includes a male component electrically connected to the electrically powered tool and configured to be inserted into the borehole of the female component. The male component includes a male component body having an external surface formed in the shape, secondary coils wound through the male component body, and a conduit extending through the male component body and having a conduit axis. The borehole axis and the conduit axis line up when the male component is inserted into the borehole of the female component. The system further includes a split downhole transformer formed by installation of the male component into the female component. Formation of the split downhole transformer allows power to transfer from a surface location to the electrically powered tool installed in the production tubing downhole in the well.

Split downhole transformer for high power applications

A downhole magnetic pump system includes a tube positioned within a wellbore at least partially filled with a fluid. A conductive wire coil is helically wrapped around the tube and is configured to generate a magnetic field in response to an electrical current passing through the coil. A standing valve assembly including a one-way valve and a travelling valve assembly also including a one-way valve are both positioned in the tube, with the travelling valve assembly positioned uphole of the standing valve assembly. The traveling valve is configured to repetitively cycle between a first position uphole of the standing valve assembly and a second position uphole of the first position in response to the electrical current repetitively switching between a first state to a second state. In this way, a portion of the fluid is displaced in an uphole direction.

This specification describes systems, methods, and architectures related to generating a plasma shield for laser operations. An example system for generating a plasma shield includes a laser head for directing a laser beam towards a target area on a workpiece. The path of the laser beam from the laser head to the target area on the workpiece is substantially surrounded by a plasma shield, which may form a gas-impermeable barrier. The plasma shield is configured to prevent the ingress of atmospheric or environmental gases, for example oxygen, into an area which would allow the gas to be in contact with the area of the workpiece being interacted with by a laser beam. The shape or location of the plasma shield may be controlled or altered using a magnetic field.

A tractor assembly includes a toroidal shaped fluid filled membrane mounted over a body and a drive system coupled with the membrane. The drive system includes a helical flight that inverts the membrane when rotated against its inner surface. A mid-section of the body includes sleeve like portions that telescope with one another and shorten a length of the body. Fluid in the membrane is forced from the mid-section and radially expands a forward portion and into contact with an inner surface of the passage, so that when the membrane is inverted while in a passage, frictional contact between the membrane and inner surface of the passage creates a force that urges the tractor assembly through a passage.

A system is provided for use with an electrical submersible pump (ESP). The system includes an ESP mounted on a tubing and a magnetic field source positioned above the ESP. The magnetic field source generates a magnetic field configured to suspend iron-containing particles above a discharge of the ESP. The magnetic field prevents an accumulation of the iron-containing particles onto components of the ESP during a powered-off state of the ESP.

One example of a gerotor pump includes an inner rotor comprising multiple teeth, the inner rotor configured to rotate about a first longitudinal gerotor pump axis. The gerotor pump also includes a hollow outer rotor including an outer surface and an inner surface having substantially identical contours, the inner surface configured to engage with the multiple teeth and to rotate about a second longitudinal gerotor pump axis. The pump includes a pump housing within which the inner rotor and the outer rotor are disposed, wherein the outer surface of the outer rotor defines gaps between the pump housing and the outer rotor.

A centrifugal pump with adaptive pump stages includes an impeller configured to provide kinetic energy to fluid flow through the pump. The impeller has multiple geometric dimensions. The pump includes a diffuser connected to the impeller that is configured to convert the kinetic energy provided by the impeller into static pressure energy to flow the fluid through the pump. The pump includes an adaptive material attached to the impeller that is configured to modify, during operation of the pump, a geometric dimension to modify fluid flow through the pump.
