Abstract: An expandable reamer apparatus and methods for reaming a borehole, wherein a laterally movable blade carried by a tubular body may be selectively positioned at an inward position and an expanded position. The laterally movable blade, held inwardly by blade-biasing elements, may be forced outwardly by drilling fluid selectively allowed to communicate therewith by way of an actuation sleeve disposed within the tubular body. Alternatively, a separation element may transmit force or pressure from the drilling fluid to the movable blade. Further, a chamber in communication with the movable blade may be pressurized by way of a downhole turbine or pump. A ridged seal wiper, compensator, movable bearing pad, fixed bearing pad preceding the movable blade, or adjustable spacer element to alter expanded blade position may be included within the expandable reamer. In addition, a drilling fluid pressure response indicating an operational characteristic of the expandable reamer may be generated.

Abstract: Entry guides for use on a tubing string comprise one or more dissolvable materials. A profile disposed on the entry guide facilitates aligning the tubing string in a desired orientation within a wellbore. For example, the profile can align the tubing string with a bore of a component disposed within the wellbore so that the tubing string can be inserted into a bore of the downhole component. After proper alignment has been achieved, the one or more dissolvable materials can be activated to disappear leaving behind the tubing string and the downhole component in their desired arrangement. One or more portion of the entry guides, including the profile, can be formed out of the dissolvable material.
