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.
