[54] METHOD FOR REMEDIATING A SCREEN-OUT DURING WELL COMPLETION
[57] Abstract: A method of completing a well involving remediating a condition of screen-out that has taken place along a zone of interest. The method includes forming a wellbore, and lining at least a lower portion of the wellbore with a string of production casing and placing a valve along the production casing, wherein the valve creates a removable barrier to fluid flow within the bore. The barrier is removed by moving the valve in the event of a screen-out. This overcomes the barrier to fluid flow, thereby exposing ports along the production casing to the subsurface formation at or below the valve. Additional pumping takes place to pump the slurry through the exposed ports, thereby remediating the condition of screen-out.
