Annular water shutoff system and methods of use thereof
Aspects of the present disclosure provide a method for sealing an annulus of a wellbore. The method including: lowering a tubular patch into a tubular to a desired seal location, wherein the tubular is disposed in a wellbore and includes one or more openings extending from an outer surface of the tubular to an inner surface of the tubular, the tubular patch including: an outer diameter of the tubular patch smaller than an inner diameter of the tubular and a first chemical disposed on an outer surface of the tubular patch; expanding the tubular patch within the tubular at the desired seal location; and exposing the first chemical to a second chemical, wherein the first chemical and second chemical react to form a sealing agent and the sealing agent expands through the one or more openings to fill an annulus between the tubular and the wellbore.
1 . A method for sealing an annulus of a wellbore, comprising:
lowering a tubular patch into a tubular to a desired seal location, wherein the tubular is disposed in the wellbore and includes one or more openings extending from an outer surface of the tubular to an inner surface of the tubular, wherein an outer diameter of the tubular patch is smaller than an inner diameter of the tubular, and wherein a first chemical is disposed on an outer surface of the tubular patch;
expanding the tubular patch within the tubular at the desired seal location; and
exposing the first chemical to a second chemical, wherein the first chemical and the second chemical react to form a sealing agent, wherein the sealing agent expands from the outer surface of the tubular patch, through the one or more openings, and outwardly from the outer surface of the tubular to fill the annulus between the tubular and the wellbore, and wherein exposing the first chemical to the second chemical includes rupturing a second chemical reservoir.
2 . The method of claim 1 , wherein the second chemical reservoir is ruptured by expanding the tubular patch.
3 . The method of claim 1 , wherein the tubular is a sand screen at the desired seal location.
4 . The method of claim 3 , wherein the desired seal location includes a portion of the sand screen.
5 . The method of claim 1 , further comprising perforating the tubular to create the one or more openings.
6 . The method of claim 1 , further comprising plugging an inner bore of the tubular patch.
7 . A method for sealing an annulus of a wellbore, comprising:
lowering a tubular patch into a tubular to a desired seal location, wherein the tubular is disposed in the wellbore including a casing and the tubular includes one or more openings extending from an outer surface of the tubular to an inner surface of the tubular, wherein an outer diameter of the tubular patch is smaller than an inner diameter of the tubular, and wherein a first chemical is disposed on an outer surface of the tubular patch;
expanding the tubular patch within the tubular at the desired seal location; and
flowing a second chemical to an outer surface of the tubular, wherein the outer surface of the tubular patch including the first chemical interacts with the second chemical, wherein the interaction between the first chemical and the second chemical forms a sealing agent, wherein the sealing agent expands from the outer surface of the tubular patch, through the one or more openings, and outwardly from the outer surface of the tubular to fill the annulus between the tubular and the wellbore, and wherein flowing the second chemical includes bullheading from a top side.
8 . The method of claim 7 , wherein the tubular is a sand screen at the desired seal location.
9 . The method of claim 7 , further comprising perforating the tubular to create the one or more openings.
10 . The method of claim 7 , wherein flowing the second chemical includes flowing the second chemical with a downhole fluid displacement tool.
11 . The method of claim 7 , further comprising deploying a plug into the tubular.
