Technical Services of Multiphase Pump System at Oil & Gas Sites

——Multiphase Commingled / Mixed-Medium (gas,oil,solid) Production and transportation

1. Service Positioning & Application Ambient

Focusing on the pain points of “low wellhead pressure, severe liquid accumulation, and rapid production decline” during the mid-to-late stages of domestic and international shale gas and conventional gas well extraction, we provide four customized services: multiphase commingled production enhancement, mixed-medium transmission to reduce backpressure, energy-efficient gas lift using well’s own gas, and specialized well treatment.

These solutions are adaptable to well clusters, single well, and main pipelines, and have been successfully validated in projects such as Yongchong, Chongqing and Weiyuan, Sichuan.

Application Types	Application Conditions	Services Purposes
Multiphase Commingled/Mixed-Medium (gas,oil,solid) Production	High wellhead pressure, small tubing-casing pressure differential, weak liquid carrying capacity	Reduce pressure by 0.3-0.8 MPa, increase daily production by 10,000 – 30,000 m³
Multiphase Mixed-Medium (gas,oil,solid) Transport	Lack of three-phase separator, high backpressure	Reduce backpressure by 1.2-1.8 MPa, increase recovery rate by 15%-20%
Well-Site Gas Lift	Gas lift Required, high nitrogen cost	Compress gas to 15-20 MPa, reduce energy consumption by 30%
Specialized Well Treatment	Low production, remote location, casing deformation, lack of power supply	Generate electricity locally by using wellsite gas, achieve negative pressure production

Full-process implementation

I. Pre-Operational Preparation

• Well Condition Survey & Solution Customization: Conduct a thorough survey of the well condition and develop customized technical solutions 
• Equipment Pre-Debugging & Transport: Pre-debug and transport equipment to the site, ensuring readiness 
• Certified Personnel & Safety Setup: Ensure all personnel are certified and implement safety controls at the site, including hazard identification and demarcation 

II. On-Site Construction

• Compact Layout Installation: Perform a compact layout installation based on the well site conditions 
• Standardized Pipeline Connection: Connect pipelines strictly following industry standards and specifications 
• System Debugging & Pressure Testing: Conduct system debugging and comprehensive pressure tests to ensure integrity and safety 

III. Operation & Maintenance (Ongoing)

• Multi-Mode Operation: Support multi-phase commingled production, commingled transmission, and gas lift operations 
• Remote Monitoring & 4-Hour Emergency Response: Implement remote monitoring systems and maintain a 4-hour emergency response capability 
• Scheduled Maintenance: Execute structured maintenance plans: Monthly, Quarterly, and Semi-Annually 

IV. Project Close-out & Handover

• Data Review & Equipment Handover: Review operational data and formally hand over equipment 
• Training & Documentation: Provide comprehensive training and assist customers to formulate documentation.
• One-Year Free Consultation & 24-Hour Fault Response: Offer one year of free technical consultation and a 24-hour fault response service 

This structured approach ensures the project progresses safely and efficiently from preparation through to stable operation and support.

3. Service Effectiveness and Cases

3.1 Key Performance Indicators (KPIs)

• Daily production increase of 15%-35%​(exceeding the industry average of 10%-25%).
• Wellhead pressure reduction of 0.3-0.8 MPa​(2-5 times the industry average).
• Equipment stability rate of 98%, with energy consumption 30-50% lower​ than the industry average.

3.2 Typical Cases

Yongchuan Platform (Chongqing):​Four shale gas wells. After implementation, wellhead pressure dropped to 1.5–2 MPa, with a daily production of 60,000–80,000 cubic meters.

Weiyuan Platform (Sichuan):​Two wells. After implementation, daily production increased from 12,000 to 16,000 cubic meters.Conventional Gas Well (Chongqing):​Multiphase commingled production + power generation skid. Daily production increased from 1,000 to 2,100 cubic meters.

4. Advantages and Guarantee

4.1 Advantages:

The technical solution is applicable to 80% of gas wells, enabling multiphase co-transport​ of gas, liquid, and solid without the need for pre-separation, simplifying the process and improving efficiency. 

The entire system adopts a full explosion-proof design, ensuring operational safety in high-risk environments and maintaining a record of zero safety incidents.

Long-Term Stability & Cost Efficiency:​ The solution is designed for long-term operation. A single retrofit supports sustained and stable production from the gas well, effectively reducing long-term maintenance and operational costs.

4.2 Guarantees:

• Fully Certified Team:​ All field operation and technical service personnel are strictly vetted and 100% hold relevant qualification certificates, guaranteeing certified and standardized operations.
• •High-Quality Core Components:​ The core components are sourced from reputable suppliers, ensuring overall equipment performance and durability from the outset.
• Comprehensive Emergency Management:​Detailed contingency plans​ are established, ensuring a swift and effective response to unforeseen events to protect both personnel and production.
