  • Method and gravel packing open holes above fracturing pressure
    Patent number: 7152677
    Abstract: The present invention provides a method for gravel packing a open-hole wellbore having a filter cake, comprising pumping a gravel slurry into a first portion of an annulus between the wellbore and a screen, at a sufficient rate and pressure to form at least a first fracture and diverting the gravel slurry to a second portion of said annulus through alternate flowpaths while providing hydraulic isolation between the first and the second portion of said interval, thereby preventing flowback from said second portion to said first portion and resulting extension of the first fracture, and thereby forming a second fracture in said second portion of said interval.
    Type: Grant

  • Gravel inflated isolation packer
    Patent number: 6575251
    Abstract: The present invention discloses apparatus and methods for use in wellbores that comprise an inflatable element. The inflatable element is adapted for inflation by gravel. One embodiment of the invention is a method of sealing an annulus in a well that comprises expanding the inflatable element with a gravel laden slurry. The inflatable element comprises a passageway communicating between an exterior and an interior of the inflatable element. The inflatable element is capable of being connected to a sand screen and the inflatable element can be inflated with the gravel laden slurry during a gravel packing of the well.
