IRDV Intelligent Remote Dual Valve

Multicycle, independent dual valve tool command and control

The IRDV intelligent remote dual valve tool allows independent command of two valves in the tool string: a testing valve and a circulating valve. Operated by the IRIS intelligent remote implementation system, the IRDV dual valve can operate both valves in multiple conditions and is immune to downhole pressure and temperature changes.

Reliable, independent control

The IRDV dual valve features nitrogen-free, hydrostatically powered testing and circulating valves in one tool. Low-pressure pulses in the annulus enable independent multicycle operation of both valves without interfering with the operation of other tools in your test string. The IRDV dual valve, as part of the Quartet downhole reservoir testing system enabled by Muzic wireless telemetry, can be controlled using wireless commands or low-pressure pulses, provides real-time tool feedback, and allows bidirectional communication for greater tool command and verification.

Reduced operating time

The IRDV dual valve enables faster, more efficient operations by issuing direct or sequential commands that eliminate the need to use complex indexing systems. The intelligent command of the system keeps a complete record of tool operations, valuable information that can be used for postjob verification. As part of the Quartet system enabled by Muzic telemetry, the dual valve allows real-time data to be wirelessly transmitted between downhole and the surface. The data can be analyzed onsite or at a remote location.

Flexible testing operations

Exclusive to the IRDV dual valve is a downhole redundancy option. This on-command mechanical override gives greater flexibility during reservoir testing, providing the ability to run multiple IRDV dual valves in your tool string.

Complementary downhole configuration

Run the IRDV dual valve as part of the Quartet-HT high-temperature downhole reservoir testing system or the Quartet system enabled by Muzic telemetry. These systems deliver the highest-quality pressure measurements and representative fluid samples with maximum safety and efficiency for altogether higher-performance reservoir testing.

Special IRDV applications

The IRDV dual valve offers a variety of command options to provide the flexibility and diversity to operate for specific applications in which low-pressure pulses, system-activation compatibility, or sequential and automatic valve operation is required.
