Abstract
A method of completing a well in a single trip includes drilling a wellbore with drilling mud, miming a single trip completion string including an upper completion, a lower completion, and a packer between the upper and lower completions into the wellbore, displacing the wellbore to solids free fluid by opening or closing a circulation sliding sleeve disposed below the packer in the lower completion, opening the circulation sliding sleeve and spotting gravel slurry in a casing annulus, closing the circulation sliding sleeve and pumping the gravel slurry down the casing annulus into an open hole annulus while taking returns through a base pipe of a sand control assembly and production tubing of the single trip completion string, opening the circulation sliding sleeve, displacing the cased hole section to completion fluid, closing the circulation sliding sleeve, and setting the packer.
