Abstract
A method of progressively gravel packing is provided which enables individual sections of a continuous wellbore portion to be gravel packed in succession. In a described embodiment, multiple well screens are positioned in a wellbore. A continuous portion of the wellbore is isolated using, for example, one or more packers, with the well screens being disposed in the isolated portion. The isolated wellbore portion is then progressively gravel packed in successive individual predetermined sections of the isolated wellbore portion.
