Formation sand sampling. The first step in gravel-pack design is to obtain a representative sample of the formation. Failure to analyze a representative sample can lead to gravel packs that fail because of plugging or the production of sand.
Resin-Coated Gravel Without Screens: Resin-coated gravel may be used as a downhole filter without installing a screen. The gravel is circulated into position as a slurry, either inside casing or open hole and then squeezed to form a plug across the production zone. Adjacent particles are bonded together by the resin, strengthening the pack.
