Three-Phase Separator • High-Accuracy Metering • Pressure Transient Analysis • Rapid Deployment for New & Workover Wells
The well testing truck has transformed how operators evaluate new and existing wells across some of the world's most demanding oilfields. Engineered as a fully self-contained mobile well testing unit, this system integrates three-phase separation, high-accuracy flow metering, pressure transient analysis, fluid sampling, and real-time data acquisition onto a single heavy-duty truck chassis.
Traditional well testing spreads require separate separator packages, metering runs, burner booms, manifold trailers, and data-acquisition cabins, all of which must be transported, positioned, interconnected, and pressure-tested before a single barrel of fluid flows. A modern mobile well testing system eliminates this complexity by consolidating every critical subsystem into one factory-tested, DOT-compliant vehicle. The integrated design also minimizes potential leak paths, reduces the site footprint, and cuts rig-up and rig-down time by up to 70 percent compared to conventional equipment spreads.
Whether the objective is a short-duration drill stem test, an extended well test spanning several weeks, or early production evaluation on a marginal asset, the well testing truck manufactured by Henan Vance Petroleum Machinery Co., Ltd. delivers the accuracy, reliability, and operational flexibility that today's exploration and production companies demand.
Horizontal three-phase separator (ASME VIII / API 12J) with upstream sand cyclone, coalescing plates, and mist extractors for clean phase separation even under high GOR or foaming conditions.
Coriolis mass flowmeters (±0.1% accuracy) for oil and water, orifice/ultrasonic gas metering, and real-time SCADA data logging with downhole gauge integration.
High-resolution pressure data capture (up to 100 readings/sec) with integrated PTA software for permeability, skin, and boundary analysis at the wellsite.
Pressurized single-phase sampling points and API 6A-rated choke manifold with positive and adjustable chokes for safe, flexible wellhead interface.
Fully enclosed, HVAC-controlled cabin with touchscreen HMI, alarm management, trend displays, and satellite/cellular remote telemetry.
Proven 6×6 or 8×8 all-wheel-drive chassis with high-torque engine and reinforced suspension for reliable access to remote and challenging well locations.
HIPPS, multi-level ESD, fire & gas detection, and zero-discharge design with full API 6A, API 12J, ASME, ATEX, and CE compliance.
Pre-commissioned plug-and-play system ready for production in 2–4 hours. Fully customizable separator, metering, and auxiliary modules.
