Abstract
Apparatus and methods for gravel packing. The method is particularly useful for deploying a sand screen assembly having shunt tubes. The apparatus can include two or more tubulars disposed about at least one expandable member. The tubulars are longitudinally aligned with one another and bundled together in a run-in position, and the bundled tubulars radially expand when the expandable member is activated.
Claims24
An apparatus for gravel packing, comprising:
- an expandable member;
- two or more tubulars disposed about the expandable member, wherein the tubulars are longitudinally aligned with one another, wherein the tubulars move radially outward when the expandable member is activated, and wherein the expandable member comprises an inflatable bladder;
- and
- a restraining device disposed radially outward from the tubulars, wherein the restraining device breaks when the expandable member moves the tubulars radially outward.
An apparatus for gravel packing, comprising:
- an expandable member;
- two or more tubulars disposed about the expandable member, wherein the tubulars are longitudinally aligned with one another, wherein the tubulars move radially outward when the expandable member is activated, and wherein the expandable member comprises a swellable material;
- a restraining device disposed radially outward from the tubulars, wherein the restraining device breaks when the expandable member moves the tubulars radially outward;
- and
- a sand screen assembly at least partially surrounded by the expandable member.
A method for deploying a sand screen assembly having shunt tubes, comprising:
- locating a bundled shunt tube assembly within a wellbore, wherein the bundled shunt tube assembly comprises:
- an expandable member;
- two or more tubulars disposed about the expandable member, wherein the tubulars are longitudinally aligned with one another, and wherein the expandable member comprises an inflatable bladder;
- and
- a restraining device disposed radially outward from the tubulars;
- moving the tubulars radially outward with the expandable member, wherein the restraining device breaks when the expandable member moves the tubulars radially outward;
- and
- locating a sand screen assembly at least partially within the tubulars.
An apparatus for gravel packing, comprising:
- an expandable member;
- two or more tubulars disposed about the expandable member, wherein the tubulars are longitudinally aligned with one another, wherein the tubulars move radially outward when the expandable member is activated, and wherein the expandable member comprises an inflatable bladder;
- and
- a restraining device disposed radially outward from the tubulars, wherein the restraining device applies a force on the tubulars in a radially inward direction, and wherein the force applied by the restraining device is less than a force applied on the tubulars in a radially outward direction by the expandable member when the expandable member is activated.
An apparatus for gravel packing, comprising:
- an expandable member;
- two or more tubulars disposed about the expandable member, wherein the tubulars are longitudinally aligned with one another, wherein the tubulars move radially outward when the expandable member is activated, and wherein the expandable member comprises a swellable material;
- a restraining device disposed radially outward from the tubulars, wherein the restraining device applies a force on the tubulars in a radially inward direction, and wherein the force applied by the restraining device is less than a force applied on the tubulars in a radially outward direction by the expandable member when the expandable member is activated;and
- a sand screen assembly at least partially surrounded by the expandable member.
