Abstract
In order to overcome the need to remove each packer after a plug and perforate operation in order to produce a well it is desirable to utilize an erodible packer that may allow one way flow. An erodible packer may be constructed of a material such as polyglycolic acid as a binder. The same packer may also allow one way flow past the packer, such as flow from the casing below the packer to the casing above the packer. The packer may erode upon the expiration of a predetermined period of time or upon exposure to an activating agent.
Claims26
A packer deployed in a wellbore comprising:
- a mandrel having an interior throughbore and an exterior;
- a one way valve in the interior throughbore of the mandrel;
- wherein the one way valve is closed to prevent fluid above the valve from passing the one way valve and is opened to allow fluid from below the valve to pass the one way valve;
- a sealing element;
- wherein the sealing element is attached to the exterior of the mandrel;
- and
- an anchor;
- wherein the anchor fixes the mandrel in place longitudinally.
A downhole assembly comprising:
- a packer having a mandrel, a one way valve, a sealing element, and an anchor;
- wherein the mandrel has an interior throughbore and an exterior;
- wherein the one way valve is in the interior throughbore of the mandrel;
- further wherein the one way valve is closed to prevent fluid above the valve from passing the one way valve and is opened to allow fluid from below the valve to pass the one way valve;
- wherein the a sealing element is attached to the exterior of the mandrel;
- and
- wherein the anchor fixes the mandrel in place longitudinally.
A downhole assembly comprising:
- a packer having a mandrel, a sealing element, and an anchor;
- wherein the mandrel has an interior throughbore and an exterior;
- wherein the sealing element is attached to the exterior of the mandrel;
- wherein the anchor fixes the mandrel in place longitudinally;
- and
- wherein the packer is at least partially an erodible material
A method of completing a well comprising:
- pumping a bottom hole assembly into a well;
- setting a packer;
- wherein the packer has a mandrel having a throughbore;
- further wherein a one way valve is located in the throughbore;
- perforating the well
- pumping in at least a second bottomhole assembly;
- setting the second packer;
- wherein the second packer has a second mandrel having a second throughbore with a second one way valve in the second throughbore;
- and
- producing the well.
