Abstract:
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.
