摘要 |
Disclosed are improved methods and apparatus for improving the production of hydrocarbons from wells having gravel pack in a production zone. The methods and apparatus basically comprise the steps of entering a gravel packed well and perforating the gravel pack screen and fracture packing the formation through the screen perforations. At least the last portion of the particulate is preferably coated with a consolidator that will form a proppant pack. Installing a second screen in the well to overlap the perforations in the gravel pack screen to prevent the particulate from reentering the well.
