Abstract
A downhole drilling tool and methods for using the tool include a body with a wall that defines an internal volume, and at least one arm attached to the wall, the at least one arm comprising a channel within a body of each arm. The at least one arm provides fluid paths connecting the internal volume to outside the wall, and the at least one arm is displaceable relative to the wall.
Claims27
A downhole drilling tool comprising:
- a body with a wall that defines an internal volume;
- and
- at least one arm attached to the wall, the at least one arm comprising a channel within a body of each arm;
- wherein the at least one arm provides fluid paths connecting the internal volume to outside the body, and
- wherein the at least one arm is displaceable relative to the wall.
2 more elements
A method comprising:
- identifying an area of interest in a wall defining a wellbore;
- sending one or more objects or solutions from a surface of a mining site to a downhole sub positioned near the area of interest;
- and
- extending one or more arms attached to the downhole sub and placing the one or more objects or solutions into the area of interest with the one or more arms.
1 more element
A wellbore system comprising:
- a wall defining a wellbore formed into a geologic formation;
- a circulation pump configured to circulate fluid through the wellbore;
- a downhole drilling tool comprising:
- a drill string sub defining an internal volume;
- and
- multiple arms attached to the circumference of the drill string sub, each arm comprising a channel within a body of each arm;
- wherein the multiple arms provide a fluid path from the internal volume of the drill string sub to an outside of the drill string sub,
- and wherein the multiple arms are displaceable relative to the drill string sub to adjust, guide, and place objects into an area of interest outside of the drill string sub;
- and
- a controller in communication with the drilling tool that sends signals to control the movements of the multiple arms.
