Abstract
A formation fracturing and gravel packing tool and associated methods provide high flow rates and volumes of slurry delivery in a relatively small bore well. In a described embodiment, a formation fracturing tool has a telescoping travel joint and a washpipe within an assembly including a packer, a circulating sleeve and a screen. The packer is set in the well, the travel joint is extended, the travel joint is locked in its extended configuration, a slurry is flowed through the circulating sleeve, the extended travel joint is latched onto the washpipe, and the travel joint and washpipe are retrieved to the earth's surface.
