Abstract
A system and a method for determining a location of an untethered drone in a wellbore are described herein. The system includes one or more markers to be placed within a wellbore casing where each of the one or more markers is configured to transmit a continuous or periodic signal. The system further includes a first sensor to be transported by the untethered drone where the first sensor is configured to sense an existence of the one or more markers.
Claims20
A system for determining a location of an untethered drone in a wellbore, the system comprising:
- one or more markers attached to a wellbore casing, each of the one or more markers configured for transmitting a continuous or periodic signal;
- and
- a first sensor connected to the untethered drone, wherein the first sensor is configured for sensing the one or more markers.
A system for determining a location of an untethered drone in a wellbore, the system comprising:
- a plurality of receiving zones defined by one or more markers positioned within a wellbore casing, the one or more markers configured for transmitting a continuous or periodic signal;
- and
- a marker receiver configured to be transported into the wellbore casing by an untethered drone, wherein the marker receiver is configured for receiving the continuous or periodic signals from the one or more markers,
- wherein a first of the plurality of receiving zones does not overlap a second of the plurality of receiving zones or the marker receiver is configured to distinguish between the first receiving zone and the second receiving zone.
A method for determining a location of an untethered drone in a wellbore, the method comprising:
- receiving, at a sensor connected to an untethered drone, a first indication of the untethered drone at a first receiving zone within a wellbore casing, wherein the first receiving zone is defined by one or more first markers positioned within the wellbore casing;
- receiving, at the sensor, a second indication of the untethered drone at a second receiving zone within the wellbore casing, wherein the second receiving zone is defined by one or more second markers positioned within the wellbore casing;
- and
- determining, via a processor, a relative location or distance of the untethered drone within the wellbore casing based on the first indication and the second indication.
