Addressable Downhole Release (ADR) Cased-Hole Tool Suite
The BHGE Addressable Downhole Release (ADR) cased-hole tool suite is a digitally controlled and remotely operated suite of devices that can be separated downhole into two pieces using a remote command, enabling the controlled release of a toolstring and leaving a clean fishing neck for the safe retrieval of wireline tools or perforating guns.
The ADR suite comprises three tool versions that are suitable for cased-hole wireline logging and perforating:
- ADR 001: 2-1⁄8-in. OD tool with a new single-piece feedthrough for increased reliability and full pass-through functionality.
- ADR 201 and ADR 202: 2-¾-in. OD tool with built-in negative and positive voltage-blocking circuitry for use with all common perforating systems
