IRIS* intelligent remote
implementation system
Downhole wireless telemetry option
that allows bidirectional communication
for tool command and verification
Reliable operation with commands unaffected by well temperature, pressure,
and deviation to ensure reliable operation,
even during stimulation
Low-pressure pulse commands or wireless commands that reduce the need
to apply high casing pressure
Tool operations recorded in memory
for postjob verification
Simplified hydraulic design for immunity
to mud debris and well-effluent solids
Large-valve operating forces for tool
reliability in presence of debris
Compatibility with all other
pressure-operated tools
Available high-temperature version
with all-ceramic multichip electronics
as well as quartz-sensor pressure
measurement technology
Mechanical override feature that
provides the flexibility to reopen tester
valve and continue well testing in case
tester valve fails in closed position
Option to run two IRDV dual valves
in the same string and operate
both independently
The IRDV* intelligent remote dual valve
combines two fullbore multicycle valves—a
tester valve and a circulating valve—that can
be cycled independently or sequentially for
increased flexibility. The dual valve is operated
by the IRIS system, which uses low-intensity
annular pressure pulses or wireless telemetry.
The commands are then implemented using
downhole hydrostatic pressure to operate the
dual valves. Tool status is wirelessly transmitted
to surface when the dual valve runs as part of
the Quartet* downhole reservoir testing system
enabled by Muzic* wireless telemetry.
Circulating
valve (closed)
The tool’s intelligent controller provides a high
level of flexibility without adding mechanical
complexity. Its mechanical section is simple, with
most seals and moving parts bathed in hydraulic
oil at hydrostatic pressure to ensure reliable tool
operation in environments with debris or heavy
mud. The circulating valve has eight 1⁄2-in-diameter
circulating ports (5⁄8 in for the large-bore tool),
enabling higher reversing and circulating rates
to reduce rig time during operations. The IRDV
dual valve has made thousands of runs in which
the fluids ranged from lightweight clear brines
to heavyweight mud systems.
Test valve (open)
Atmospheric
chamber
The flexible IRIS system includes automatic
valve sequences that optimize wellsite operation.
The IRDV dual valve is insensitive to pressure
fluctuations from the operation of other tools,
common operational procedures, and hydraulic
fracturing. The hydraulic system and reference
pressure for the tool is automatically referenced
with the hydrostatic pressure, allowing operation
going in and coming out of the well at any depth.
Enhanced with 100% ceramic multichip technology
and all-quartz pressure measurements, the
high-temperature version is qualified to reliably
operate in reservoirs up to 410 degF.

§Not applicable.
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 better reservoir testing.
