         21 . A method of installing downhole equipment in a wellbore, the method comprising:
 forming a profile in a wall of the wellbore using a laser;   inserting a piece of downhole equipment into the wellbore; and   engaging the profile formed in the wall of the wellbore with the piece of downhole equipment.   
     
     
         22 . The method of  claim 21 , wherein forming the profile comprises forming a female profile in the wall of the wellbore. 
     
     
         23 . The method of  claim 22 , wherein forming the female profile in the wall of the wellbore comprises forming a recess in a casing installed in the wellbore. 
     
     
         24 . The method of  claim 23 , wherein forming the recess in the casing installed in the wellbore comprises forming a recess that only extends partway through the casing. 
     
     
         25 . The method of  claim 22 , wherein the female profile is sized and positioned to receive extendable dogs on the piece of downhole equipment. 
     
     
         26 . The method of  claim 23 , wherein forming the female profile comprises forming an annular recess extending around an inner diameter of the casing. 
     
     
         27 . The method of  claim 23 , wherein forming the female profile comprises forming multiple discrete recesses formed at a common distance from an entrance of the wellbore. 
     
     
         28 . The method of  claim 21 , wherein the piece of downhole equipment is a seal, a pump, liner hanger, or a downhole steam generator. 
     
     
         29 . The method of  claim 23 , comprising inserting the piece of downhole equipment into the wellbore such that extendable dogs on the piece of downhole equipment are aligned with the recess; and
 extending the extendable dogs on the piece of downhole equipment to matingly engage the recess.   
     
     
         30 . The method of  claim 21 , where forming the profile comprises forming a window extending through a casing installed in the wellbore. 
     
     
         31 . The method of  claim 30 , wherein the window is sized to receive a junction. 
     
     
         32 . The method of  claim 31 , comprising deploying the junction into the wellbore such that the junction is aligned with the window; and inserting the junction into and extending through the window. 
     
     
         33 . The method of  claim 32 , comprising sealing the window after inserting the junction into and extending through the window.
