Abstract
Techniques for controlling lost circulation while drilling include while drilling a wellbore, encountering a high-loss circulation zone by a bottomhole assembly; responsive to encountering the high-loss circulation zone, releasing a first lost circulation media retained within the bottomhole assembly; and receiving a second lost circulation media, by the bottomhole assembly, from circulation fluid circulated from a topside facility.
Claims20
A method, comprising:
- while drilling a wellbore, encountering a high-loss circulation zone by a bottomhole assembly that comprises one or more actuable gates and a trigger;
- responsive to encountering the high-loss circulation zone and to actuation of the actuable gates by the trigger, releasing a first lost circulation media retained within the bottomhole assembly;
- capturing, with a camera of the bottomhole assembly, a first image of a portion of the high-loss circulation zone prior to release of the first lost circulation media from the bottomhole assembly in response to actuation of the one or more actuable gates by the trigger;
- capturing with the camera, a second image of a portion of the high-loss circulation zone subsequent to release of the first lost circulation media from the bottomhole assembly in response to actuation of the one or more actuable gates by the trigger;
- and
- receiving a second lost circulation media, by the bottomhole assembly, from circulation fluid circulated from a topside facility.
