Abstract
Provided is a gauge mandrel, a sensing system, and a well system. The gauge mandrel, in one aspect, includes a tubular having a length (Lt), an internal diameter (Di) and a width (W), the internal diameter (Di) and the width (W) defining a sidewall thickness (t), the tubular defining a primary fluid passageway. The gauge mandrel, in accordance with this aspect, further includes a gauge cavity extending along at least a portion of the length (Lt) of the tubular and located entirely within the sidewall thickness (t), the gauge cavity having an insertion end configured to accept a gauge sensor.
Claims19
A gauge mandrel for use with a gauge sensor, comprising:
- a tubular having a length (Lt), an internal diameter (Di) and a width (W), the internal diameter (Di) and the width (W) defining a sidewall thickness (t), the tubular defining a primary fluid passageway;
- and
- a gauge cavity extending along at least a portion of the length (Lt) of the tubular and located entirely within the sidewall thickness (t), the gauge cavity having an insertion end configured to accept a gauge sensor, wherein the gauge cavity is located outside of primary fluid passageway, the gauge cavity having an exit end exiting the sidewall thickness (t) opposite the insertion end.
A sensing system, comprising:
- tubing;
- a gauge mandrel coupled to the tubing, the gauge mandrel including:
- a tubular having a length (Lt), an internal diameter (Di) and a width (W), the internal diameter (Di) and the width (W) defining a sidewall thickness (t), the tubular defining a primary fluid passageway;
- and
- a gauge cavity extending along at least a portion of the length (Lt) of the tubular and located entirely within the sidewall thickness (t), the gauge cavity having an insertion end, wherein the gauge cavity is located outside of primary fluid passageway, the gauge cavity having an exit end exiting the sidewall thickness (t) opposite the insertion end;
- and
- a gauge sensor positioned at least partially within the gauge cavity, the gauge sensor configured to measure temperatures or pressures within the gauge mandrel or outside of the gauge mandrel.
A well system, comprising:
- a wellbore located in a subterranean formation;
- production tubing located in the wellbore;
- a submersible pump located in the wellbore and fluidly coupled to the production tubing;
- and
- a sensing system located in the wellbore and fluidly coupled to the production tubing proximate the submersible pump, the sensing system including:
- a gauge mandrel, the gauge mandrel including:
- a tubular having a length (Lt), an internal diameter (Di) and a width (W), the internal diameter (Di) and the width (W) defining a sidewall thickness (t), the tubular defining a primary fluid passageway;
- and
- a gauge cavity extending along at least a portion of the length (Lt) of the tubular and located entirely within the sidewall thickness (t), the gauge cavity having an insertion end, wherein the gauge cavity is located outside of primary fluid passageway, the gauge cavity having an exit end exiting the sidewall thickness (t) opposite the insertion end;
- and
- a gauge sensor positioned at least partially within the gauge cavity, the gauge sensor configured to measure temperatures or pressures within the gauge mandrel or outside of the gauge mandrel.
