Zusammenfassung: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.
