ABSTRACT:
Method and apparatus for gravel packing wells are provided. Selected intervals of wells may be fractured before gravel packing. The open area of a screen device and the number of perforations exposed to slurry are increased as gravel is pumped into a well during gravel packing operations. Means for creating back-pressure on perforations not yet covered with gravel is provided to decrease flow of particles into the casing during gravel packing operations. Gravel pack screen assemblies by which flow area can be incrementally increased are disclosed, along with apparatus for providing desired back-pressure on open perforations.
