Abstract
Systems, apparatuses, and methods for producing fluids from a wellbore wherein fluids may be communicated through an aperture in a wall of the wellbore. A laser can then be used to seal the aperture in the wall of the wellbore. The wall of the wellbore may include a casing, and the laser can be used to seal the aperture in the wall of the wellbore by fusing apertures in the casing shut. Fusing the aperture in the casing can involve heating the casing such that opposite sides of the aperture fuse together or can involve selectively laser sintering fusible powders. The wall of the wellbore can be an open hole and using a laser to seal the aperture can include sealing the aperture in side surfaces of the open hole by glazing the surface of hole extending into a subterranean formation.
