Overview
The Solartron ISA Dualstream 3 is a field-deployable, non-intrusive multiphase flow and water fraction analyzer engineered for real-time, high-fidelity measurement of wet gas streams in upstream oil and gas operations. Based on dual-path differential pressure (Venturi-based) and multi-path ultrasonic transit-time principles, the system simultaneously quantifies total volumetric flow rate, gas velocity, liquid holdup, and water cut—without phase separation, radioactive sources, or moving parts. Its core architecture leverages over three decades of empirical fluid dynamics research conducted by Solartron ISA on complex wet gas behavior under varying pressure, temperature, and flow regimes. Designed specifically for wellhead, manifold, and trunkline applications, the Dualstream 3 delivers traceable, repeatable measurements compliant with ISO 5167 (differential pressure) and ISO/TR 15142 (multiphase flow metering guidance), supporting reservoir management, hydrocarbon allocation, and water breakthrough detection.
Key Features
- Non-intrusive, clamp-on multi-path ultrasonic sensor array enabling full-bore water fraction profiling without flow disruption or pressure drop
- Integrated Venturi differential pressure section for high-accuracy gas-phase velocity and total mass flow derivation
- Real-time phase fraction computation across 0–100% water cut, validated for condensate-rich, high-velocity wet gas flows (up to Mach 0.3)
- No radioactive components—eliminates regulatory licensing, transport restrictions, and radiation safety protocols required by gamma densitometers
- Plug-and-play compact mechanical design optimized for offshore platforms, remote desert wells, and arctic environments (operating range: −40 °C to +85 °C)
- IP66/NEMA 4X-rated electronics enclosure with SIL2-certified safety integrity for hazardous area installations (ATEX/IECEx Zone 1)
Sample Compatibility & Compliance
The Dualstream 3 is validated for continuous operation in single-well and multi-well test separators handling natural gas, associated gas, and retrograde condensate streams containing entrained water, glycol, methanol, or corrosion inhibitors. It maintains measurement stability under slug flow, annular mist, and stratified flow regimes typical of aging reservoirs and water-drive fields. The system conforms to API RP 14E (design of offshore production systems), ISO 14310 (Vx multiphase flowmeter verification), and meets data integrity requirements per FDA 21 CFR Part 11 when integrated with approved SCADA historians. Calibration traceability is maintained to NPL (UK) and PTB (Germany) standards via factory-accredited wet-gas loop testing.
Software & Data Management
The embedded firmware supports Modbus TCP, OPC UA, and DNP3 protocols for seamless integration into existing DCS, SCADA, and cloud-based production surveillance platforms. The optional Dualstream Insight software suite provides real-time visualization of water cut trends, gas–liquid interface dynamics, and cumulative hydrocarbon allocation reports aligned with PRMS and SPEE guidelines. Audit trails include timestamped configuration changes, calibration events, and sensor health diagnostics—fully compliant with GLP/GMP documentation workflows. All raw sensor data (transit times, differential pressures, temperature gradients) are stored locally for ≥30 days and exportable in CSV/NetCDF format for third-party reservoir simulation input.
Applications
- Well-by-well allocation accounting for joint venture partnerships and fiscal reporting
- Early water breakthrough identification in waterflood or CO₂-EOR projects
- Real-time optimization of chemical injection rates (e.g., demulsifiers, hydrate inhibitors)
- Gas lift monitoring and choke performance evaluation at subsea manifolds
- Validation of dynamic multiphase simulators (e.g., OLGA, Pipesim) using field-observed phase distributions
- Regulatory compliance reporting for environmental discharge limits (e.g., OSPAR, BSEE)
FAQ
Does the Dualstream 3 require radioactive sources or nuclear licensing?
No. It uses only ultrasonic and differential pressure sensing—fully exempt from IAEA, NRC, or national nuclear regulatory frameworks.
Can it operate in high-pressure offshore wells (>10,000 psi)?
Yes. Standard configurations support up to 15,000 psi working pressure with ASTM A182 F22 alloy wetted parts and ASME B16.5 Class 2500 flanges.
How frequently does it require recalibration?
Factory calibration remains valid for 24 months under stable operating conditions; field verification is recommended annually using dry-gas zero-check and known-water-cut reference tests.
Is it compatible with sour gas containing H₂S?
Yes. All wetted surfaces are available in duplex stainless steel (UNS S32205) or Inconel 625, certified to NACE MR0175/ISO 15156 for service in H₂S partial pressures up to 100 kPa.
What installation footprint is required?
Minimum straight-pipe run is 5D upstream and 3D downstream of the Venturi; ultrasonic sensor mounting requires no pipe cutting—clamp-on design enables retrofitting within 4 hours.
