Abstract
A method of suspending a well comprises the steps of lowering a tool assembly into a into the well, the tool assembly comprising an upper housing including a connection means for lowering the tool, a first heating element, and, a quantity of bismuth disposed in proximity to the heating element, and a lower tool to be left in the well comprising a mandrel and an annular seal connected to the mandrel. The first heating element is actuated to melt the bismuth so that it forms in an annular space defined between the lower tool and the casing of the well above the annular seal to seal the well, releasing the upper housing from the lower tool retrieving the upper housing.
Claims (17)
1. A method of suspending a well comprising the steps of lowering a tool assembly into a into the well the tool assembly comprising an upper housing including a connection means for lowering the tool, a first heating element, a quantity of bismuth disposed in proximity to the heating element, and a lower tool to be left in the well comprising a mandrel, and an annular seal connected to the mandrel actuating the first heating element to melt the bismuth so that it forms in an annular space defined between the lower tool and the casing of the well above the annular seal to seal the well, releasing the upper housing from the lower tool retrieving the upper housing.
2. A method according to claim 1 wherein the first heating element is included in the upper housing.
3. A method according to either previous claim wherein the bismuth initially secures the upper housing to the lower tool, and the step of melting the bismuth releases the upper housing from the lower tool, and including the step of retrieving the upper housing.
3. A method according to any previous claim wherein the tool assembly is lowered on a wireline.
4. A method according to any previous claim wherein the bismuth is cast around first heating element.
5. A method according to any previous claim wherein a pressure sensor is included in the lower tool, including the steps of testing the pressure of the well prior to actuating the second heating element equalising the pressure above and below the annular seal if necessary.
6. A method according to any previous claim wherein a pre cast bismuth plug is included in the lower tool.
7. A method according to any previous claim wherein the tool assembly includes a brush or brushes which clean the surface of the casing where the bismuth plug is to be cast.
8. A method according to any previous claim wherein the annular seal is set against a chamfered surface to allow the seal to flex before it is finally positioned.
9. A method according to any previous claim wherein the brush or brushes are set against chamfered surfaces to allow the seal to flex before it is finally positioned.
10. A method according to any previous claim wherein tool assembly includes a cavity which can be filled with bismuth in shot form.
11. A method according to any previous claim wherein mandrel of the lower tool is secured to the upper housing by a shaped slot, such that the lower tool can move relative to the upper housing when the bismuth is initially melted, and allowing the release of the upper housing from the lower tool.
12. A method according to any previous claim wherein the lower tool includes a fishing profile and a retrieval tool is deployed in the well to engage with the fishing profile, and retrieve the lower tool.
13. A method according to claim 12 wherein the lower tool further comprises a second heating element an electrical connection a container including the steps connecting the retrieval tool to the electrical connection and supplying power to the second heating element melting the bismuth above the annular seal and releasing the lower tool for retrieval so that it flows into the container, releasing the lower tool from the well casing retrieve the lower tool and bismuth.
14. A tool assembly according to any previous claim.
15. A lower tool according to any previous claim.
16. An upper housing according to any previous claim .
17. A retrieval tool according to any previous claim.
