Single trip completion system with open hole gravel pack go/stop pumping

A method of completing a well in a single trip, comprising:

• drilling a wellbore with a water-based or oil-based drilling mud, the wellbore comprising:
• a cased hole section;
• and an open hole section;
• running a single trip completion string into the wellbore, the single trip completion string comprising:
• an upper completion;
• a lower completion below the upper completion;
• and a packer disposed between the upper completion and the lower completion;
• displacing a solids-free fluid out of the wellbore by pumping a fluid into the wellbore and 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.
