Abstract
A method that includes receiving, by a processing device communicatively coupled to one or more sensors residing at or near a downhole end of a drill string, location information from the one or more sensors. The location information includes a location of particles adhered to a wall of a downhole section of a first wellbore. The method also includes determining, by the processing device and based on the location information, a trajectory of a second wellbore configured to intersect the first wellbore at the downhole section of the first wellbore. The method also includes transmitting, by the processing device to a receiver communicatively coupled to the processing device, the trajectory of the second wellbore to an operator or a controller to drill the second wellbore.
Claims20
A method comprising:
- receiving, by a processing device communicatively coupled to one or more sensors residing at or near a downhole end of a drill string, location information from the one or more sensors, the location information including a location of particles adhered to a wall of a downhole section of a first wellbore;
- determining, by the processing device and based on the location information, a trajectory of a second wellbore configured to intersect the first wellbore at the downhole section of the first wellbore;
- and
- transmitting, by the processing device to a receiver communicatively coupled to the processing device, the trajectory of the second wellbore to an operator or a controller to drill the second wellbore.
A method comprising:
- deploying a drill string within a first wellbore, the drill string comprising one or more sensors residing at or near a downhole end of the drill string, the one or more sensors configured to detect location information including a location of particles adhered to a wall of a downhole section of the first wellbore, the downhole section extending from an obstruction at the wellbore to a downhole end of the wellbore;
- determining, based on the location information detected by the one or more sensors, a trajectory of a second wellbore, the trajectory extending from an uphole section of the first wellbore uphole of the obstruction to the downhole section of the first wellbore;
- and
- drilling the second wellbore along the trajectory of the second wellbore.
A drilling assembly comprising:
- a drill string configured to be disposed within a first wellbore;
- a processor coupled to the drill string;
- and
- one or more particle sensors communicatively coupled to the processor and attached to a downhole end of the drill string, the one or more particle sensors configured to detect and transmit, to the processor, location information including a location of particles adhered to a wall of a downhole section of the first wellbore, wherein the processor is configured to determine, based on the location information, a trajectory of a second wellbore intersecting the downhole section of the first wellbore to drill the second wellbore along the trajectory of the second wellbore.
