Abstract
Methods may include selecting a slot size of apertures to control sand production including formation fines in fluid from a subterranean zone. The slot size may be selected based on a distribution of sizes of particles in fluid from the subterranean zone. A laser may be used to form apertures with the selected slot size in a casing installed in a wellbore in the subterranean zone. Systems and apparatuses may be configured to perform the above operations.
Claims6
A method comprising:
- selecting a slot size of apertures to control sand production including formation fines in fluid from a subterranean zone, the slot size selected based on a distribution of sizes of particles in the subterranean zone;
- using a laser to form apertures with the selected slot size in a casing installed in a wellbore in the subterranean zone;
- and
- sealing apertures in the wellbore using the laser to change a flow distribution of the wellbore in response to levels of particles in fluid being produced from the wellbore.
