Abstract
A release tool can include an inner mandrel, an electric motor assembly, and an engagement member. The inner mandrel is displaceable by the electric motor assembly between a position in which the inner mandrel supports the engagement member and prevents separation of portions of the release tool, and another position in which the engagement member is not supported by the inner mandrel and separation of the portions of the release tool is permitted. A method of separating portions of a release tool in a well can include transmitting an electrical signal to an electrical motor assembly of the release tool, displacing an inner mandrel of the release tool in response to the transmitting, and separating the portions of the release tool after the displacing.
Claims18
A release tool for use in a subterranean well, the release tool comprising:
- an inner mandrel;
- an electric motor assembly;
- and
- at least one engagement member,
- in which the inner mandrel is displaceable by the electric motor assembly between a first position in which the inner mandrel supports the at least one engagement member and prevents separation of first and second portions of the release tool, and a second position in which the at least one engagement member is not supported by the inner mandrel and separation of the first and second portions of the release tool is permitted, and
- in which the electric motor assembly is configured to rotate the inner mandrel between the first and second positions.
A method of separating first and second portions of a release tool in a subterranean well, the method comprising:
- transmitting an electrical signal to an electrical motor assembly of the release tool;
- displacing an inner mandrel of the release tool in response to the transmitting, in which the displacing comprises rotating the inner mandrel;
- and
- separating the first and second portions of the release tool after the displacing.
