Abstract
A completion assembly for treating a wellbore. The completion assembly can include a tubular member having a bore formed axially therethrough and a port formed radially therethrough. An annulus can be disposed radially outward from the tubular member and the port can provide fluid communication between the annulus and the bore. A packer can be coupled to the tubular member and adapted to isolate first and second portions of the annulus. A seal bore can be coupled to the tubular member such that the port is disposed axially between the packer and the seal bore. A straddle seal can be adapted to contact the packer and the seal bore to prevent fluid flow between the annulus and the bore. The straddle seal can be run into the wellbore with the completion assembly in a single trip.
