Downhole rotary slip ring joint to allow rotation of assemblies with electrical and fiber optic control lines

A well system, comprising:

• a wellbore;
• a wellbore access tool positioned near the wellbore with a conveyance;
• a downhole rotary slip ring joint positioned between the conveyance and the wellbore access tool, the downhole rotary slip ring joint including:
• an outer mandrel;
• an inner mandrel operable to rotate relative to the outer mandrel without a required relative axial motion relative to the outer mandrel;
• a coupling feature positioned between the outer mandrel and the inner mandrel, the coupling feature configured to prevent the inner mandrel and outer mandrel from axially decoupling from one another while downhole;
• an outer mandrel communication connection coupled to the outer mandrel;
• an inner mandrel communication connection coupled to the inner mandrel;
• and
• a passageway extending through the outer mandrel and the inner mandrel, the passageway configured to provide continuous coupling between the outer mandrel communication connection and the inner mandrel communication connection regardless of a rotation of the inner mandrel relative to the outer mandrel, wherein the downhole rotary slip ring joint is operable to be coupled to the wellbore access tool;
• and
• a first communication line coupled to the outer mandrel communication connection and a second communication line coupled to the inner mandrel communication connection.

A method for accessing a wellbore, comprising:

• coupling a wellbore access tool to a conveyance, the wellbore access tool and the conveyance having a downhole rotary slip ring joint positioned therebetween, the downhole rotary slip ring joint including:
• an outer mandrel;
• an inner mandrel operable to rotate relative to the outer mandrel without a required relative axial motion relative to the outer mandrel;
• a coupling feature positioned between the outer mandrel and the inner mandrel, the coupling feature configured to prevent the inner mandrel and outer mandrel from axially decoupling from one another while downhole;
• an outer mandrel communication connection coupled to the outer mandrel;
• an inner mandrel communication connection coupled to the inner mandrel;
• and
• a passageway extending through the outer mandrel and the inner mandrel, the passageway configured to provide continuous coupling between the outer mandrel communication connection and the inner mandrel communication connection regardless of a rotation of the inner mandrel relative to the outer mandrel, wherein the downhole rotary slip ring joint is operable to be coupled to the wellbore access tool, wherein a first communication line is coupled to the outer mandrel communication connection and a second communication line is coupled to the inner mandrel communication connection;
• and
• positioning the wellbore access tool within the wellbore as the inner mandrel rotates relative to the outer mandrel.
