Abstract
Presented is a system and method for disconnecting a plurality of wireline tools from a string of wireline tools while maintaining operation of the wireline tools remaining with the string of wireline tools. The disconnection is non-destructive and allows a reconnection of the disconnected tools after retrieval from the well. The system also enables testing of the disconnection mechanism before deploying the wireline tool string into the well.
