Methods for injecting a consolidation fluid into a wellbore at a subterranian location
Abstract
Disclosed are apparatuses and methods for stabilizing portions of a subterranean formation and controlling the production of water from those subterranean formations. In one aspect, a method of treating a plurality of discrete portions of a subterranean formation penetrated by a wellbore, the method comprising the steps of: (a) moving a treatment tool through the wellbore on work tubing to a desired subterranean location, wherein the treatment tool comprises: (i) a fluidic oscillator; and (ii) a lower packer positioned below the fluidic oscillator; (b) expanding the cross-section of the lower packer to engage the wellbore, thereby isolating a portion of the wellbore from another portion below the lower packer; (c) injecting a consolidation fluid through the tubing and through the fluidic oscillator into the isolated portion of the wellbore; (d) reducing the cross-section of the lower packer, thereby disengaging the tool from the wellbore.
Claims
exact text as granted — not AI-modified1 . A method of treating a portion of a subterranean formation penetrated by a wellbore, the method comprising the steps of:
(a) moving a treatment tool through the wellbore on tubing to a desired subterranean location, wherein the treatment tool comprises:
(i) a fluidic oscillator; and
(ii) a lower packer positioned below the fluidic oscillator;
(b) expanding the cross-section of the lower packer to engage the wellbore, thereby isolating a portion of the wellbore from another portion of the wellbore below the lower packer; (c) injecting a consolidation fluid through the tubing and through the fluidic oscillator into the isolated portion of the wellbore; (d) reducing the cross-section of the lower packer, thereby disengaging the tool from the wellbore.
2 . The method according to claim 1 , wherein the lower packer comprises an a lower inflatable packer.
3 . The method according to claim 2 , wherein the tool further comprises at least one hydraulic control line to the lower inflatable packer.
4 . The method according to claim 3 , wherein the step of expanding the cross-section of the lower packer to engage the wellbore further comprises using the hydraulic control line to inflate the lower inflatable packer.
5 . The method according to claim 3 , wherein the step of reducing the cross-section of the lower packer to disengage the wellbore further comprises using the hydraulic control line to deflate the lower inflatable packer.
6 . The method according to claim 1 , further comprising the step of injecting a flushing fluid after the step of injecting a consolidation fluid.
7 . The method according to claim 1 , further comprising repeating the sequence of steps (a) through (d) at least one additional time at a different desired subterranean location.
8 . The method of claim 1 , wherein the treatment tool is a through-tubing tool for passing through tubing having a smaller cross section area than the cross section area of the wellbore at the treatment location and wherein the lower packer is radially compressible sufficient to pass through the smaller tubing.
9 . The method of claim 1 , additionally comprising the step of injecting fluids while moving the treatment tool through a portion of the wellbore.
10 . The method of claim 1 , wherein the moving step comprises passing the injection apparatus through a restriction in the well having a cross section area less than the cross section area of the lower packer when in the expanded condition.
11 . A method of treating a portion of a subterranean formation penetrated by a wellbore, the method comprising the steps of:
(a) moving a treatment tool through the wellbore on tubing to a desired subterranean location, wherein the treatment tool comprises:
(i) a fluidic oscillator;
(ii) an upper packer positioned above the fluidic oscillator; and
(iii) a lower packer positioned below the fluidic oscillator;
(b) expanding the cross-section of each of the upper packer and the lower packer to engage the wellbore, thereby isolating a portion of the wellbore between the upper packer and the lower packer; (c) injecting a consolidation fluid through the tubing and through the fluidic oscillator into the isolated portion of the wellbore; (d) reducing the cross-section of the upper packer and the lower packer, thereby disengaging the tool from the wellbore.
12 . The method according to claim 11 , wherein the upper packer and the lower packer each comprise an upper inflatable packer and a lower inflatable packer, respectively.
13 . The method according to claim 12 , wherein the tool further comprises at least one hydraulic control line to the upper inflatable packer and to the lower inflatable packer.
14 . The method according to claim 13 , wherein the step of expanding the cross-section of each of the upper packer and the lower packer to engage the wellbore further comprises using the hydraulic control line to inflate each of the upper inflatable packer and the lower inflatable packer.
15 . The method according to claim 13 , wherein the step of reducing the cross-section of each of the upper packer and the lower packer to disengage the wellbore further comprises using the hydraulic control line to deflate each of the upper inflatable packer and the lower inflatable packer.
16 . The method according to claim 11 , further comprising the step of injecting a flushing fluid after the step of injecting a consolidation fluid.
17 . The method according to claim 11 , further comprising repeating the sequence of steps (a) through (d) at least one additional time at a different desired subterranean location.
18 . The method of claim 11 , wherein the treatment tool is a through-tubing tool for passing through tubing having a smaller cross section area than the cross section area of the wellbore at the treatment location and wherein the upper and lower packers are radially compressible sufficient to pass through the smaller tubing.
19 . The method of claim 11 , additionally comprising the step of injecting fluids while moving the treatment tool through a portion of the wellbore.
20 . The method of claim 1 , wherein the moving step comprises passing the injection apparatus through a restriction in the well having a cross section area less than the cross section area of the upper packer and of the lower packer when in the expanded condition.Join the waitlist — get patent alerts
