  • Patent number: 5287928
    Abstract: An apparatus for repairing a well completion having a gravel-packed annulus formed by a liner and a well casing, the annulus having at least one region within the gravel pack which is devoid of gravel.
    Type: Grant

  • Patent number: 5165475
    Abstract: A method for gravel packing a wellbore where a resin-coated sand or "gravel" is utilized. First, the wellbore is perforated at the productive interval in a manner sufficient to hydraulically fracture the formation. Afterwards, the formation is hydraulically fractured via a frac fluid containing a resin-coated sand. During this fracturing operation, a resultant fracture is propped with the resin-coated sand. The frac fluid is pumped down the wellbore until "screen out" occurs at perforations in the wellbore. The resin-coated sand is allowed to remain in the fracture, perforations, and wellbore until a permeable, porous consolidated mass is formed. After the mass has formed, excess consolidated sand is removed from the wellbore. When the formation is produced, formation solids are contained by the consolidated mass in the fracture and perforations.
