Logging tool

A wellbore assembly, comprising:

• a wellbore string configured to be disposed within a wellbore;
• a logging assembly comprising an interior volume, the logging assembly coupled to the wellbore string and defining, with a wall of the wellbore, and annulus;
• and
• one or more logging tools residing within the interior volume of the logging assembly;
• wherein the logging assembly comprises a fluid inlet uphole of the interior volume, a fluid outlet downhole of the interior volume, and a fluid conduit fluidly isolated from the interior volume of the logging assembly and from the one or more logging tools and extending from the fluid inlet to the fluid outlet to direct fluid received from the wellbore string into the fluid conduit through the fluid inlet, to the fluid outlet, and out of the logging assembly into the annulus to remove obstructions in the annulus.

A method, comprising:

• moving, along a wellbore, a drill string comprising a logging assembly forming, with the wellbore, an annulus, the logging assembly comprising one or more logging tools disposed within an interior volume of the logging assembly, the logging assembly comprising a fluid inlet uphole of the interior volume, inlet, a fluid outlet downhole of the interior volume, and a fluid conduit fluidly isolated from the interior volume of the logging assembly and from the one or more logging tools and extending from the fluid inlet to the fluid outlet;
• flowing fluid from the drill string, into the fluid conduit through the fluid inlet, out of the fluid conduit through the fluid outlet, and out of the logging assembly into the annulus, removing obstructions in the annulus;
• and
• logging, while flowing the fluid, the wellbore with the one or more logging tools, the one or more logging tools fluidly decoupled from the fluid conduit and from the drill string.

A wellbore assembly, comprising:

• a drill string configured to be disposed within a wellbore;
• a logging assembly coupled to a downhole end of the drill string, and comprising:
• a sub assembly fluidly coupled to the drill string and defining an interior volume, the sub assembly defining, with a wall of the wellbore, an annulus, and
• a shoe coupled to a downhole end of the sub assembly;
• and
• one or more logging tools disposed within the interior volume of the logging assembly;
• wherein the sub assembly comprises a fluid inlet arranged to receive fluid from the drill string, the shoe comprising a fluid outlet, and the sub assembly comprising a fluid conduit fluidly isolated from the interior volume of the sub assembly and extending from the fluid inlet to the fluid outlet to direct the fluid from the fluid inlet, through the fluid conduit, and into the shoe through the fluid outlet for the fluid to exit the shoe through a shoe outlet into the annulus to remove obstructions in the annulus;
• wherein the sub assembly further comprises a wet connect sub and a side entry sub both disposed between the drill string and a housing of the sub assembly.

A wellbore assembly, comprising:

• a wellbore string configured to be disposed within a wellbore;
• a logging assembly comprising an interior volume, the logging assembly coupled to the wellbore string and defining, with a wall of the wellbore, and annulus;
• and
• one or more logging tools residing within the interior volume of the logging assembly;
• wherein the logging assembly comprises a fluid inlet uphole of the interior volume, a fluid outlet downhole of the interior volume, and a fluid conduit fluidly isolated from the interior volume of the logging assembly and extending from the fluid inlet to the fluid outlet to direct fluid received from the wellbore string into the fluid conduit through the fluid inlet, to the fluid outlet, and out of the logging assembly into the annulus to remove obstructions in the annulus;
• wherein the logging assembly comprises a housing and a valve, the housing comprising the fluid conduit and the fluid conduit fluidly isolated from the one or more logging tools and extending along an external surface of the housing;
• and
• wherein the logging assembly further comprises a wet connect sub and a side entry sub both disposed between the wellbore string and the logging assembly, the side entry sub residing between the wellbore string and the valve, the side entry sub comprising an aperture arranged to receive a cable extending from the wet connect to a terranean surface of the wellbore.

A method, comprising:

• moving, along a wellbore, a drill string comprising a logging assembly forming, with the wellbore, an annulus, the logging assembly comprising one or more logging tools disposed within an interior volume of the logging assembly, the logging assembly comprising a fluid inlet, inlet, a fluid outlet downhole of the interior volume, and a fluid conduit fluidly isolated from the interior volume of the logging assembly and extending from the fluid inlet to the fluid outlet;
• flowing fluid from the drill string, into the fluid conduit through the fluid inlet, out of the fluid conduit through the fluid outlet, and out of the logging assembly into the annulus, removing obstructions in the annulus;
• and
• logging, while flowing the fluid, the wellbore with the one or more logging tools, the one or more logging tools fluidly decoupled from the fluid conduit and from the drill string;
• wherein the logging assembly further comprises a wet connect sub and a side entry sub uphole of the wet connect sub, the side entry sub comprising an aperture arranged to receive a cable extending from the wet connect to a terranean surface of the wellbore;
• and the method further comprises disconnecting, upon determining that the logging tool is stuck within the wellbore, the cable.
