Abstract
A wellbore assembly includes a drill string, a logging assembly, and one or more logging tools. The logging assembly is coupled to a downhole end of the drill string and includes a sub assembly and a shoe. The sub assembly is fluidly coupled to the drill string, defines an interior volume, and defines, with a wall of the wellbore, an annulus. The one or more logging tools are disposed within the interior volume of the logging assembly. The sub assembly includes a fluid inlet and the shoe includes a fluid outlet. The sub assembly includes a fluid conduit fluidly isolated from the interior volume of the sub assembly. The fluid conduit extends from the fluid inlet to the fluid outlet to flow the fluid from the fluid inlet into the shoe for the fluid to exit the shoe through a shoe outlet to remove obstructions in the annulus.
Claims19
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 comprising a tubular housing defining an internal surface, the internal surface 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 tubular housing comprises at least one longitudinal groove disposed on the internal surface, the sub assembly comprises a fluid inlet uphole of the interior volume and is arranged to receive fluid from the drill string, the shoe comprising a fluid outlet downhole of the interior volume, and the sub assembly comprising a flexible fluid conduit disposed along the at least one longitudinal groove and fluidly isolated from the interior volume of the sub assembly, the flexible fluid conduit extending from the fluid inlet to the fluid outlet to direct the fluid from the fluid inlet, through the flexible 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.
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, an 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, a fluid conduit, and a sub assembly, the 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, the sub assembly fluidly coupled to the wellbore string and at least partially defining the interior volume, the sub assembly at least partially defining, with the wall of the wellbore, the annulus, the sub assembly comprising a wet connect sub and a side entry sub both disposed between the wellbore string and a housing of the sub assembly, wherein the side entry sub resides between the wellbore string and the wet connect sub, the side entry sub comprising an aperture arranged to receive an electrical cable extending from the wet connect sub to a terranean surface of the wellbore.
A method, comprising:
- moving, along a wellbore, a drill string comprising a logging assembly and a sub assembly, the sub assembly comprising a tubular housing defining an internal surface, at least one longitudinal groove disposed on the internal surface, and a flexible fluid conduit disposed along the at least one longitudinal groove and fluidly isolated from an interior volume of the sub assembly, the logging assembly and the sub 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 interior volume of the logging assembly including the interior volume of the sub assembly, the logging assembly comprising 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, the flexible fluid conduit extending from the fluid inlet to the fluid outlet to direct the fluid from the fluid inlet, through the flexible fluid conduit;
- 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 through the flexible fluid conduit;
- 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, wherein the side entry sub resides between the drill string and the wet connect sub, the side entry sub comprising an aperture arranged to receive an electrical cable extending from the wet connect sub to a terranean surface of the wellbore.
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;
