ABSTRACT:
A method for completing and increasing the production rate from a cased well which may produce solids through perforations during production is provided. A gravel pack screen is placed in the well along with equipment in the tubing string to control flow from inside to outside the tubing below a production packer. The rig used to place the equipment may then be released from the well. The well is then hydraulically fractured. If the well is producing from a high permeability zone, the hydraulic fracture is preferably formed with the tip screen-out technique. The method can also be used in a well already containing production tubing without moving a rig on the well to remove the tubing from the well and can be used in a well not yet perforated by adding tubing-conveyed perforating apparatus below the screen.
