A system and method for hydraulic fracturing a subterranean formation with fracturing fluid to generate fractures, and intermittently adjusting a characteristic of the fracturing fluid conveying proppant to form pillars of proppant in the fractures.

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 system for controlling tubing member assembly diameter includes a control unit, a computing device, a tubing member assembly, and an elastomer member. The tubing member assembly includes an outer pipe member that defines a static diameter and an inner pipe member having an outer surface and defining a dynamic diameter that changes from a first inner pipe member value to a second inner pipe member value. The elastomer member is disposed between the outer pipe member and the inner pipe member such that an inner area of the elastomer member is disposed on the outer surface of the inner pipe member. The elastomer member expands from a first position to a second position to constrict the dynamic diameter from the first inner pipe member value to the second inner pipe member value responsive to receiving an electrical signal from the control unit.

A method for reviving a well may include deploying a tube between a casing and a wellbore tubular of the well. The tube may extend from a surface through a port at a wellhead of the well to a section of the well at a depth above a packer. The method may include pumping down, through the tube, non-corrosive material into the section of the well. The well may be blocked below the packer by well blockage. The method may include destroying the well blockage by dissolving the well blockage using the non-corrosive material. The method may include pumping up, through the wellhead, the well blockage dissolved in the non-corrosive material.
