Abstract
A bridge plug arrangement includes a plug having an upper end and a bottom end. The bridge plug arrangement also optionally includes a cylindrical seat. The bridge plug arrangement further includes a tubular member. The tubular member may be part of a casing string. The tubular member is configured to receive the plug and, when used, the seat. The plug and/or the seat may be fabricated from a frangible material. Also disclosed is a method for diverting fluids in a wellbore using the bridge plug arrangement. The method may include landing the plug onto the seat within the wellbore below a subsurface zone of interest. Treatment fluids are then injected into the wellbore, where they are diverted through perforations and into a formation. The plug and/or seat is then optionally broken into a plurality of pieces through use of a downward mechanical force.
