Abstract

A well abandonment tool comprises a housing locatable within a wellbore, the housing including a compartment containing sealing material, an activator to initiate the release of the sealing material, an anchor for securing the tool in the wellbore, and a slickline for deploying the housing in the wellbore. The sealing material may be thermite, and the activator may be an ignitor that initiates the thermite reaction. The ignitor may include a battery and element, the activation process includes making a contact such that the battery causes the element to heat to ignite the thermite.

Claims (14)

Claims
1. A well abandonment tool comprising: a housing locatable within a wellbore, the housing including a compartment containing sealing material an activator to initiate the release of the sealing material an anchor for securing the tool in the wellbore a slickline for deploying the housing in the wellbore.
2. A well abandonment tool according to claim 1 wherein the sealing material is thermite, and the activator is an ignitor that initiates the thermite reaction
3. A well abandonment tool according to claim 1 or 2 wherein the ignitor includes a battery and element, the activation process includes making a contact such that the battery causes the element to heat to ignite the thermite.
4. A well abandonment tool according to any previous claim wherein the sealing material is two part resin deployed, and the activator includes a static mixing discharge head.
5. A well abandonment tool according to claim 1 or 2 wherein the sealing material is two co-reactive chemicals.
6. A well abandonment tool according to claim 1 or 2 wherein the sealing material is a low temperature alloy such as bismuth
7. A well abandonment tool according to any previous claim wherein the anchor is set by pressuring the wellbore above the tool
8. A well abandonment tool according to any previous claim wherein the tool is deployed on a running tool, the running tool being releasably secured to the tool by a low melting point material, such that the melting of the low melting point material releases the running tool.
9. A well abandonment tool according to any previous claim wherein the tool is deployed on a releasable running tool, and the ignitor is actuated by release of the running tool.
10. A well abandonment tool according to any previous claim wherein the slickline includes a fibre optic cable in its inner diameter .
11. A well abandonment tool according to any previous claim wherein the fibre optic cable transmits sensed data from the well abandonment tool.
12. A well abandonment tool according to any previous claim wherein the sensed data includes the temperature or activation of the sealing material.
13. A well abandonment tool according to any previous claim wherein the fibre optic cable interfaces with the thermite such that the thermite reaction can be initiated using the fibre optic cable .
14. A method of abandoning a well tool comprising the steps of: deploying a first tool according to any of the previous claims releasing the first tool from the slickline and activating the thermite deploying a second tool according to any of the previous claims releasing the second tool from the slickline and activating the thermite.
