Sleeve apparatus, downhole system, and method

A downhole system comprising an assembly configured to extend through a borehole, the assembly having an interior defining a flowbore, the downhole system further comprising:

• a sleeve apparatus connected along the assembly, the sleeve apparatus having a longitudinal axis and an interior, the sleeve apparatus further including:
• a tubular having a plurality of ports providing a length of fluidic access between the interior of the sleeve apparatus and an exterior of the tubular, the length measured with respect to the longitudinal axis;
• and,
• a sleeve disposed within the tubular and configured to move longitudinally with respect to the longitudinal axis, the sleeve having a plurality of apertures misaligned with the plurality of ports in a closed condition of the sleeve apparatus and at least substantially aligned with the plurality of ports in a fully open condition of the sleeve apparatus, the sleeve further having a plurality of non-apertured sections aligned with the plurality of ports in the closed condition;
• wherein a longitudinal shifting distance of the sleeve to move the sleeve apparatus from the closed condition to the fully open condition of the sleeve apparatus exposing the plurality of ports to the interior of the sleeve apparatus is less than the length of fluidic access provided by the plurality of ports in the fully open condition.

A method of accessing an annulus in a borehole, the method comprising:

• running a downhole assembly into a borehole, the downhole assembly having an interior defining a flowbore, and further comprising a sleeve apparatus connected along the assembly, the sleeve apparatus having a longitudinal axis and an interior, the sleeve apparatus further including a tubular having a plurality of ports providing a length of fluidic access between the interior of the sleeve apparatus and an exterior of the tubular, the length measured with respect to the longitudinal axis;
• and, a sleeve disposed within the tubular and configured to move longitudinally with respect to the longitudinal axis, the sleeve having a plurality of apertures misaligned with the plurality of ports in a closed condition of the sleeve apparatus and at least substantially aligned with the plurality of ports in a fully open condition of the sleeve apparatus, the sleeve further having a plurality of non-apertured sections aligned with the plurality of ports in the closed condition;
• and,
• shifting the sleeve within the tubular to expose the plurality of ports to the interior of the sleeve apparatus in the fully opened condition of the sleeve apparatus;
• wherein a longitudinal shifting distance of the sleeve to move the sleeve apparatus from the closed condition to the fully open condition of the sleeve apparatus is less than the length of fluidic access provided by the plurality of ports in the fully open condition.
