Abstract
An example system includes a laser tool configured for downhole movement. The laser tool includes an optical assembly configured to shape a laser beam for output. The laser beam may have an optical power of at least one kilowatt (1 kW). A housing contains the optical assembly. The housing is configured for movement to direct the output laser beam within a wellbore. The movement includes rotation of the laser tool around a longitudinal axis of the housing and tilting the housing relative to a longitudinal axis of the wellbore. A control system is configured to control at least one of the movement of the housing or an operation of the optical assembly to direct the output laser beam within the wellbore.
Claims22
A system comprising:
- a laser tool comprising:
- an optical assembly configured to shape a laser beam for output;
- and
- a housing that contains the optical assembly, the housing comprising a side output port disposed within a side surface of the housing, the side output port comprising a fiber optic medium for transmitting the laser beam from inside the housing to outside the housing, the housing further comprising a bottom port disposed within a bottom surface of the housing and configured to output the laser beam, the housing being configured for movement to direct the laser beam within a wellbore, the movement comprising rotation of the laser tool at least partly around a longitudinal axis of the housing and tilting the housing relative to a longitudinal axis of the wellbore;
- and
- a control system to control at least one of the movement of the housing and an operation of the optical assembly to direct the laser beam within the wellbore.
A system comprising:
- multiple laser tools that are connected, each of the multiple laser tools being for use at a different depth within a wellbore formed within a hydrocarbon formation, each of the multiple laser tools comprising:
- an optical assembly configured to shape a laser beam for output;
- and a housing that contains the optical assembly, the housing comprising a side output port disposed within a side surface of the housing, the side output port comprising a fiber optic medium for transmitting the laser beam from inside the housing to outside the housing, the housing further comprising a bottom port disposed within a bottom surface of the housing and configured to output the laser beam, the housing being configured for movement to direct the laser beam within the wellbore, the movement comprising rotation of the housing around a longitudinal axis of the housing and tilting the housing relative to the longitudinal axis;
- and
- a control system to control movement of each housing of the multiple laser tools, where the multiple laser tools cut through one or more structures of the wellbore via both sublimation and spallation.
