  • Publication number: 20190330947
    Abstract: A detonator activated wireline release tool is provided for use in geological well operations that enables the wireline cable to be easily released from tool string equipment upon activation of a detonator housed within the release tool. The release tool has a wireline subassembly portion that is connected to a tool string subassembly portion during assembly. It is sometimes necessary to disconnect the wireline subassembly from the tool string subassembly at a time when accessing the either is not physically possible. Such release is achieved by sending an electronic signal that detonates an explosive load which actuates a latch through an expansion chamber. The latch shifts and allows the finger flanges previously connecting the subassemblies to disengage, thus releasing the subassemblies.
