A filter tool for a wellbore may include an outer housing, a filtration system, at least one filter tool sensor, and a filter motor. The outer housing may have an interior wall comprising at least one port and an exterior wall defining an exterior surface of the filter tool. The exterior wall may be movable between a first position in which the exterior wall covers the at least one port in the interior wall and a second position in which the exterior wall uncovers the at least one port in the interior wall. The interior wall of the outer housing and the filtration system may cooperate to define a collection chamber. The filter motor may move the exterior wall of the outer housing between the first position and the second position. Embodiments also include systems and methods employing the filter tool.

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.

Systems and methods for collecting debris in a subterranean well include a wellbore cleanout tool having a tool housing with a tool bore. The wellbore cleanout tool further includes a power source, a wire in electrical communication with the power source, and a core member located within the tool bore. The wire is wound around the core member with a first end and a second end of the wire in electrical connection with a positive terminal and a negative terminal of the power source, respectively. A plurality of magnetic bars are spaced around the core member. A sleeve member is moveable between an uphole position where the sleeve member circumscribes the plurality of magnetic bars, and a downhole position where the sleeve member is located downhole of a portion of the plurality of magnetic bars and can be a collection basket. The wellbore cleanout tool further has a permanent magnet.

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.

Various systems, methods, and devices are disclosed for handling contaminants in a wellbore or riser. A washpipe debris trap (WPDT) traps contaminants traveling up a wellbore from a downhole location, and the WPDT may serve as an indicator for a breached screen in a downhole location. A marine riser reversing tool (MRRT) may reverse the flow of fluid between a workstring conduit and an annulus between the workstring and the wellbore such that fluid rises to the wellhead with greater velocity. A bi-directional chamber trap (BDCT) may be utilized in a wellbore operation to remove contaminants from a fluid.

A downhole apparatus for collecting solids fallback in the tubing of an oil producing borehole comprises two or more baskets to collect the solids fall back, each basket partially occupying a portion of the inner cross section of the tubing, leaving a portion of the inner cross section of the tubing having an unrestricted flow path. The baskets when considered in plan view along longitudinal axis of the tubing are distributed such that together they cover substantially the whole area of the tubing while leaving an unobstructed non-straight flowpath around the baskets.

A hollow milling-bit defines a first interior flow passage. A junk catcher sub is connected to the hollow milling-bit and positioned between the hollow milling-bit and the uphole end. A junk recovery tube is connected to the junk catcher sub and positioned between the junk catcher sub and the uphole end. A reverse circulation diverter sub is connected to the junk recovery tube and positioned between the junk recovery tube and the uphole end. The reverse circulation diverter sub includes a ball seat configured to receive a ball. The first recirculation passage fluidically connects the interior flow passage to an outer surface of the tool. The second recirculation passage fluidically connects the interior flow passage to an outer surface of the tool. A catch basket that defines openings is connected to a downhole end of the reverse circulation diverter sub and positioned in the third interior flow passage in-line.

A wellbore gauge cutter apparatus includes a sampling body defining a central recess extending from an inlet at a first end to an outlet at a second end. The apparatus further includes a gauge cutter connected to the sampling body configured to dislodge particles from an inner wall of a wellbore. The sampling body includes an inner wall defining the central recess, a hollow cylindrical divider having a central aperture, a first flow path defined in the central aperture of the hollow cylindrical divider, a second flow path defined between an outer wall of the hollow cylindrical divider and the inner wall of the sampling body, and a fluid permeable screen arranged in the first flow path or the second flow The fluid permeable screen is configured to collect a portion the particles dislodged by the gauge cutter.

A downhole apparatus for collecting solids fallback in the tubing of an oil producing borehole comprises two or more baskets to collect the solids fall back, each basket partially occupying a portion of the inner cross section of the tubing, leaving a portion of the inner cross section of the tubing having an unrestricted flow path. The baskets when considered in plan view along longitudinal axis of the tubing are distributed such that together they cover substantially the whole area of the tubing while leaving an unobstructed non-straight flowpath around the baskets.

An apparatus includes a first body, a second body, a shear pin, and a divider. The first body includes a coupling. The second body includes a cutter blade. The shear pin is configured to hold the position of the second body relative to the first body in an open position. The coupling is configured to couple the first body to the second body in a closed position. In the open position, the apparatus defines first and second flow paths for fluids and solids to pass through the apparatus. The first flow path is defined through the first body and through an inner bore of the divider. The second flow path is defined through the first body and through an annulus surrounding the divider. In the closed position, the second flow path is closed, such that solids remain in the annulus surrounding the divider.
