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