GEODynamics’ patent pending wireline Release™ technology provides a reliable option for freeing from a downhole tool string that has unexpectedly become stuck. During normal perforating operations, a solid state switch automatically connects the wireline to the tool/gun string when the voltage rises above 35V, regardless of polarity. This allows the surface to communicate with the release tool in isolation from the rest of the string when powered up to less than 35V.


The release tool is commonly run below the rope socket and the CCL. In the unfortunate event that it must be used, the tool is activated with state-of-the-art addressable technology administered from the GEODynamics EPIC™ Command or third-party shooting panel with tool interface panel. After the release command is executed, the tool separates at the engineered release point, allowing the wireline string to be pulled to surface.
