An oil well tool operable to be deployed downhole on a production string including a tubular member having a wall extending from a first end to a second end opposite the first end and the wall forming a plurality of apertures. The oil well tool also includes a mesh screen coupled to an inner surface of the wall of the tubular member and covering the plurality of apertures.

The present disclosure relates to a separating device for removing solid particles from fluids, and to the use of said separating device for removing solid particles from fluids.

A full-length screen pipe hole protection device and method with pressurized hole packing in a soft coal seam relates to the field of gas drainage technologies. The device includes a grouting system, a drainage system and a hole fixing system. The grouting system injects a pressurized sealing material into a borehole through a pressure pump to increase a sealing effect of the borehole. The drainage system drains gas in the middle of air holes on metal baffle plates and hole fixing screen pipes through a drainage pipe to increase flowability of gas. The hole fixing system is inside the borehole and fixed with the metal baffle plates, and the hole fixing screen pipes are fixedly connected with each other through fitting mouths and fitting buckles. The device is fixedly mounted in the gas drainage borehole. After hole packing, the drainage pipe is connected with a drainage pump to drain gas.

A system for a well completions operation includes a packed filtration screen assembly removably attached around a perforated portion of a liner, where the packed filtration screen assembly has an inner slotted basket, an outer slotted basket positioned concentrically around the inner slotted basket, and gravel held in an annular space between the inner slotted basket and the outer slotted basket and axial end caps located at opposite axial ends of the annular space.

A sand control assembly includes a base pipe having at least one perforation, a housing, and at least one inflow control device integrated within the housing via an associated ring secured to the housing and the base pipe, the at least one inflow control device and the associated ring creating a seal. The housing is disposed around the exterior of the base pipe, and the housing is secured to a bypass ring at a first end of the housing and secured to the base pipe at a second end of the housing via a weld end ring. A longitudinal axis of the at least one inflow control device is parallel to a longitudinal axis of the base pipe.

Disclosed are methods, systems, and computer-readable medium to perform operations including: determining a level of accumulation of a hydrocarbon-water emulsion in an annulus of a wellbore; based on the level of accumulation, determining an operating setting of a hydrocarbon-water separator and operating the hydrocarbon-water separator at the operating setting, where the hydrocarbon-water separator separates the hydrocarbon-water emulsion into water and a hydrocarbon fluid; activating, in response to a first sensor detecting a first water level in the annulus, a pump that pumps the water from the annulus into a water zone below the wellbore; and deactivating the pump in response to a second sensor detecting a second water level in the annulus, where the second sensor is located below the first sensor.

A filter sub which includes a tubular sub housing and a strainer insert. The strainer insert has (i) a tubular strainer body, (ii) a plurality of helical grooves formed through a sidewall of the strainer body, and (iii) at least one of the helical grooves extending at least 360° around the strainer body.

The present disclosure relates to a separating device for removing solid particles from fluids, and to the use of said separating device for removing solid particles from fluids.

An electromechanical actuator having a servo valve is described. The servo valve has a valve housing having a wall surrounding the servo valve, the valve housing having a first end and a second end with the servo valve positioned between the first end and the second end. The valve housing also includes at least one debris vent positioned on an exterior surface of the wall between the servo valve and the first end of the valve housing, the debris vent having a first dimension; and, at least one fluid vent positioned on the exterior surface of the wall between the servo valve and the second end of the valve housing, the fluid vent having a second dimension. The first dimension is smaller than the second dimension.

A waterflood completion system usable in a well includes a mandrel disposed on a tubing string deployable down a borehole. The mandrel has a side pocket with one or more ports for communicating the tubing string with an annulus of the borehole A waterflood regulator arrangement is connected to the mandrel and has at least one screen directly included therein spaced from the mandrel and lying adjacent the tubing string.
