In 2026, global oil and gas multiphase transportation technology is further advancing from traditional surface wellhead transportation toward Deepwater Multiphase Boosting, HPHT Subsea Pumping, and Long-Distance Subsea Tieback. SLB OneSubsea secured an order this year for a high-pressure high-temperature multiphase boosting system for Shenandoah deepwater project, with the system designed for conditions exceeding 15,000 psi demonstrating that subsea boosting is becoming an important technical pathway for extending field life, reducing wellhead back pressure, and enhancing recovery rates. The biggest challenge of multiphase pumps is not simply "getting the oil out," but simultaneously handling crude oil, natural, produced water, and even sand particles. Core design parameters include Gas Volume Fraction (GVF), Gas-Liquid Ratio, Slug Flow, Differential Pressure, Flow Assurance, and Sand Tolerance. For high-GVF, highly fluctuating unseparated wellstreams, Helico-Axial Multiphase Pumps and Twin Screw Multiphaseumps offer greater advantages. OneSubsea multiphase pumps are capable of handling-gas-content wellstreams; Sulzer's publicly disclosed helico-axial multiph pumps cover 0–100% GVF with a maximum differential pressure of approximately 200 bar. The-screw pathway is more suitable for high gas content, viscosity variations, and slug flow conditions. Leistritz's multiphase employ a Twin Screw positive displacement structure, capable of adapting to changing GVF throughout the field life cycle through speed adjustment, and avoiding dry running and overheating under high-gas-content conditions through liquid recirculation. Jiangsu Haifa Machinery Manufacturing Co., Ltd. www.jslgpump.com has established API 610 OH2, BB2, BB5, VS6, and API 685 and gas process pump platforms. truly high-GVF wellhead raw oil-gas-water multiphase transportation, dedicated multiphase pumps should be; whereas for gas-bearing crude oil, condensate, light hydrocarbons, high-pressure export after primary separation, OH2, BB2, BB5, or low-NPSH VS6 can be adopted depending on operating conditions. Jiangsu Haifa's existing BB5 platform features a maximum head of approximately 3,400 m and a maximum design pressure of approximately 35 MPa, suitable for high-pressure liquid boosting crude oil export, and oilfield auxiliary high-pressure processes. The core of Jiang Ligong Group's future oil and gas multiphase transportation equipment will be the integrated capabilities of High-GVF Handling, Slug-Tolerant Pumping, Subsea Boosting, Low-NPSH Design, Rotor Dynamics, and Predictive Condition Monitoring.
