Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
170 words
A method for completing a well and hydraulically fracturing a productive zone penetrated by the well, the well having casing and tubing, the casing having perforations into the productive zone, comprising the steps of: (a) placing in the casing through the tubing a screen assembly, the screen assembly comprising a gravel pack screen, the gravel pack screen having a lower end and an upper end and being placed below the tubing and opposite the perforations in the casing, the gravel pack screen being closed on the lower end and connected to a blank pipe on the upper end, the blank pipe being connected to a vent screen, the vent screen having a lower end and an upper end, the blank pipe being connected to the lower end, the upper end of the vent screen being closed; (b) hydraulically fracturing the well by pumping fluid and proppant down the tubing string and around the screen assembly; and (c) washing proppant from the tubing and casing down to below the vent screen.
Claim 2
Independent Claim
170 words
A method for completing a well and hydraulically fracturing a productive zone penetrated by the well, the well having casing and tubing, the casing having perforations into the productive zone, comprising the steps of: (a) placing in the casing through the tubing a screen assembly, the screen assembly comprising a gravel pack screen, the gravel pack screen having a lower end and an upper end and being placed below the tubing and opposite the perforations in the casing, the gravel pack screen being closed on the lower end and connected to a blank pipe on the upper end, the blank pipe being connected to a vent screen, the vent screen having a lower end and an upper end, the blank pipe being connected to the lower end, the upper end of the vent screen being closed; (b) hydraulically fracturing the well by pumping fluid and proppant down the tubing string and around the screen assembly; and (c) washing proppant from the tubing and casing down to below the vent screen.
Claim 3
Dependent Claim
13 words

Claim 4
Dependent Claim
12 words
The method of claim 2 wherein the centralizer is a bow centralizer.
Claim 5
Dependent Claim
