Abstract
Methods of gravel packing a subterranean well located subsea utilizing through-the-flowline techniques are disclosed in which a sand slurry is pumped downwardly through one pipe of a dual pipe string and outwardly through an H-type crossover member (14, 15) into a perforated casing area (20) until the area is fully packed. In one method, the H-type crossover member (14) is provided with a flangible plug (14h) to allow bypass of the sand slurry once the perforated casing area is filled with aggregate. In another method, the gravel packing of the perforated casing area is accomplished utilizing a special TFL tool (25) which provides for injection of the sand slurry through an H-type crossover member (15) into the perforated casing area (20).
