Abstract: A method for completing a well in a single trip, including: inserting a completion tool assembly into the well, the completion tool assembly having a gravel packing assembly and a service tool assembly slidably positioned substantially within an interior cavity in the gravel packing assembly; removably coupling the service tool assembly and the gravel packing assembly; plugging at a first location, whereby fluid is blocked from flowing through the interior channel; diverting fluid blocked by the plugging at the first location through a first fluid flow path to an exterior of the completion tool assembly; circulating a gravel pack slurry through the completion tool assembly; plugging at a second location, whereby fluid is blocked from flowing through the interior channel; diverting fluid blocked by the plugging at the second location through a second flow path that reenters the interior channel at a location distal of the first and second plugging locations; and circulating a filter cake stimulating fluid thro

Abstract: A method for completing a well in a single trip is described, which includes inserting a completion tool assembly into the wellbore. The completion tool assembly includes a gravel packing assembly having a central channel substantially therethrough and a service tool assembly slidably positioned within the central channel. The service tool includes a pressure pulsating rotating jetting tool, connectable to a washpipe via a differential valve. By selectively dropping a plurality of plugging devices into the completion tool, multiple operations may be selectively performed in the wellbore in a single trip. In this way, the gravel packing and stimulating operations may be performed by a single completion tool assembly in a single trip into the wellbore, thus reducing the cost and time for performing the gravel packing and stimulating operations.
