A device can include a collar positioned in a wellbore that can include an outer wall. The outer wall can define an inner area of the collar and can prevent fluid flow between the inner area of the collar and an outer area of the collar during a hydraulic fracturing process. The collar can be removed or dissolved to form a flow path to allow production fluid to flow between the inner area of the collar and the outer area of the collar subsequent to the hydraulic fracturing process.

Well tool having a removable collar for allowing production fluid flow

A method includes conveying a wellbore isolation device into a wellbore, the wellbore isolation device including a primary valve arranged within a central flow passage. A fluid is then circulated through the central flow passage and into a tubing attached to a downhole end of the wellbore isolation device and in fluid communication with the central flow passage. The primary valve is moved from a first position to a second position and thereby diverts the fluid into an annulus defined between the wellbore and the wellbore isolation device. The primary valve may then be moved to seal the central flow passage and thereby prevent the fluid from flowing into the annulus or into the tubing.
