Abstract

A gravel pack system includes a tool string having an inner string member, an outer string member, and a passage arranged between the outer string member and the inner string member. A packing element is provided on the outer string member. A first valve is coupled to one of the outer string member and the inner string member outwardly of the packing element in a downhole direction. The first valve fluidically connects the passage and the open hole wellbore. The first valve is configured and disposed to shift from a closed position to an open position. A second valve is coupled to one of the outer string member and the inner string member outwardly of the packing element in an uphole direction. The second valve selectively fluidically connects the passage and the open hole wellbore. The second valve shifts from an open position to a closed position.

First claim

1 . A multi-zone single treatment gravel pack system comprising:
a tool string including an inner string member, an outer string member, and a passage arranged between the outer string member and the inner string member; at least one selectively deployable packing element provided on the outer string member; a first valve coupled to one of the outer string member and the inner string member outwardly of the at least one selectively deployable packing element in a downhole direction, the first valve selectively fluidically connecting the passage and the open hole wellbore, the first valve being configured and disposed to shift from a closed position to an open position; and a second valve coupled to one of the outer string member and the inner string member outwardly of the at least one selectively deployable packing element in an uphole direction, the second valve selectively fluidically connecting the passage and the open hole wellbore, the second valve being configured and disposed to shift from an open position to a closed position.

2 . The multi-zone single treatment gravel pack system according to claim 1 , wherein the first valve includes a shroud member configured and disposed to direct fluid outwardly and downwardly from the outer string member into the open hole wellbore.

3 . The multi-zone single treatment gravel pack system according to claim 1 , wherein the outer string member includes a plurality of openings.

4 . The multi-zone single treatment gravel pack system according to claim 3 , wherein the inner string member comprises a selectively shiftable isolation sleeve, the second valve being formed on the isolation sleeve.

5 . The multi-zone single treatment gravel pack system according to claim 1 , wherein the at least one packing element includes a first packing element and a second packing element spaced from the first packing element.

6 . A completion system comprising:
an uphole portion including at least one pump and a fluid storage system fluidically connected to the at least one pump; and a downhole portion including a completion string extending into an open hole wellbore, the completion string including a multi-zone single treatment gravel pack system comprising:
a tool string including an inner string member, an outer string member, and a passage arranged between the outer string member and the inner string member;
at least one selectively deployable packing element provided on the outer string member;
a first valve coupled to one of the outer string member and the inner string member axially outwardly of the at least one selectively deployable packing element in a downhole direction, the first valve selectively fluidically connecting the passage and the open hole wellbore the first valve being configured and disposed to shift from a closed position to an open position; and
a second valve coupled to one of the outer string member and the inner string member axially outwardly of the at least one selectively deployable packing element in an uphole direction, the second valve selectively fluidically connecting the passage and the open hole wellbore, the second valve being configured and disposed to shift from an open position to a closed position.

7 . The completion system according to claim 6 , wherein the first valve includes a shroud member configured and disposed to direct fluid outwardly and downwardly from the outer string member into the open hole wellbore to reduce wellbore wall erosion.

8 . The completion system according to claim 6 , wherein the outer string member includes a plurality of openings.

9 . The completion system according to claim 8 , wherein the inner string member comprises a selectively shiftable isolation sleeve, the second valve being formed on the isolation sleeve.

10 . The completion system according to claim 6 , wherein the at least one packing element includes a first packing element and a second packing element spaced from the first packing element.

11 . A method of multi-zone single treatment gravel packing an open hole wellbore comprising:
guiding a completion string including a gravel pack system into the open hole wellbore; deploying at least one packing element provided on an outer string member to isolate a portion of the open hole wellbore; opening a first valve arranged outwardly of the at least one packing element in a downhole direction; introducing a downhole fluid into the open hole wellbore; guiding the downhole fluid through openings formed in the outer string member outwardly of the at least one packing element in an uphole direction; passing the downhole fluid radially inwardly along the at least one packing element through a passage arranged between the outer string member and an inner string member; guiding the downhole fluid through the first valve back into the open hole wellbore; and closing a second valve arranged at the openings in the outer string member.

12 . The method of claim 11 , wherein closing the second valve includes shifting an isolation sleeve relative to the plurality of openings.

13 . The method of claim 11 , wherein deploying the at least one packing element includes deploying a first packing element arranged outwardly of an isolation sleeve in a downhole direction and deploying a second packing element arranged outwardly of the isolation sleeve in an uphole direction.

14 . The method of claim 13 , wherein passing the downhole fluid radially inwardly along the at least one packing element includes passing the downhole fluid radially inwardly of the first packing element and the second packing element.

15 . The method of claim 14 , wherein guiding the downhole fluid through the first valve back into the open hole wellbore includes gravel packing the open hole wellbore outwardly of the second packing element in the downhole direction.

16 . The method of claim 15 , further comprising: introducing the downhole fluid into the open hole wellbore outwardly of the second packing element in an uphole direction.

17 . The method of claim 11 , wherein guiding the downhole fluid through the first valve back into the open hole wellbore includes passing the downhole fluid along a shroud member outwardly and downwardly of the outer string member.

18 . The method of claim 11 , wherein closing a second valve includes guiding a shifting tool in an uphole direction to engage inner string member closing the openings.
