Wellbore laser operations

A method comprising:

• characterizing a subterranean formation;
• selecting a first shape of an aperture and a second, different shape of an aperture based on characteristics of the subterranean formation;
• using a laser beam to form a first aperture of the selected first shape in the wall of the wellbore;
• and
• using the laser beam to form a second aperture of the selected second, different shape in the wall of the wellbore;
• and
• in response to levels of particles in a fluid being produced from the wellbore, operating the laser beam to change a flow distribution of the wellbore, wherein operating the laser beam to change the flow distribution in the wellbore comprises sealing one or both of the first or second apertures in the wellbore using the laser beam.

A method comprising:

• selecting a first orientation of an aperture geometry and a second, different orientation of an aperture geometry based on characteristics of a subterranean formation;
• using a laser to form a first aperture having the aperture geometry of the selected first orientation in the wall of the wellbore;
• and
• using the laser to form a second aperture having the aperture geometry of the selected second, different orientation in the wall of the wellbore;
• and
• in response to levels of particles in a fluid being produced from the wellbore, operating the laser to change a flow distribution of the wellbore, wherein operating the laser to change the flow distribution in the wellbore comprises sealing one or both of the first or second apertures in the wellbore using the laser.
