1. A method comprising:
- selecting an aperture geometry and aperture size to filter solids from fluid from a subterranean zone, the aperture geometry and aperture size each selected based on a distribution of sizes of particles in the subterranean zone;
using a laser to form slots with the selected aperture geometry and aperture size in a casing installed in a well in the subterranean zone; and
in response to levels of particles in fluid from the well, operating the laser to change a flow distribution of the well, wherein operating the laser to change the flow distribution of the well comprises sealing apertures in a wellbore wall using the laser.

Abstract
Systems, methods, and apparatuses involve selecting an aperture geometry to filter solids from fluid from a subterranean zone, the aperture geometry selected based on a distribution of sizes of particles in the fluid from the subterranean zone. A laser can be used to form slots with the selected aperture geometry in a casing installed in a well in the subterranean zone, the aperture geometry having a size selected based on the distribution of sizes of the particles.
