Gauge carrier protective housing

A gauge carrier protective housing for use on a tool string of a wireline or a slickline that passes through a well borehole which traverses earth formations and contains fluid, the gauge carrier protective housing for use with a gauge carrier having one or more sensors exposed to the fluid in the well borehole when in operation, the gauge carrier protective housing comprising:

• a protective tubular structure encasing a gauge carrier, a first shock absorbing assembly, and a second shock absorbing assembly, the protective tubular structure
• dimensioned and configured to surround a gauge carrier with the first shock absorbing assembly on a first end of the protective tubular structure corresponding to a first end of a gauge carrier and the second shock absorbing assembly on a second end of the protective tubular structure corresponding to a second end of a gauge carrier,
• having an outer wall and an inner wall, wherein in operation the outer wall faces a well borehole and is in contact with fluid in the well borehole, and wherein the inner wall is configured to face a gauge carrier and the first and second shock absorbing assemblies, and
• having a plurality of apertures to permit passage of fluid from the well borehole to one or more sensors exposed to fluid and that are carried on a gauge carrier,
• wherein
• the first end of the protective tubular structure is attached to a coupling that is configured and dimensioned to attach to the tool string, the coupling having a string-side connecting structure that is configured and dimensioned to connect to the tool string, and a tube-side connecting structure that is configured and dimensioned to connect to the first end of the protective tubular structure;
• the second end of the protective tubular structure is attached to an adapter that is configured and dimensioned to attach to one of an additional section of the tool string, the wireline link jar, the gauge cutter or the terminal end, the adapter having a string-side connecting structure that is configured and dimensioned to connect to one of an additional section of the tool string, the wireline link jar, the gauge cutter or the terminal end, and a tube-side connecting structure that is configured and dimensioned to connect to the second end of the protective tubular structure.
