Abstract

A plug assembly used in a wellbore fracturing process includes an annular housing that is set in the wellbore, and a ball that lands and seats in the housing. The housing and ball form a pressure barrier in the wellbore that isolates one portion of the wellbore from an adjacent portion. Pressurizing the portion of the wellbore isolated by the plug assembly generates fractures in a formation around that portion of the wellbore. The ball is not reactive with wellbore fluid or affected by wellbore conditions. Fluid communication across the plug assembly is reestablished by fracturing or milling the ball within the housing. Wellbore operations are conducted by inserting downhole tools through a bore axially formed in the housing.
