Oilfield Oil Production Microgrid Solution
Summary: Gobi oilfield solar-diesel-storage microgrid reduces diesel consumption and carbon emissions at remote well sites while enhancing power supply resilience.
Solution Overview
For remote oilfield well sites in gobi and desert areas, a microgrid is built with PV, energy storage and diesel generation to reduce energy consumption per ton of oil production and carbon emissions.
Key Points
- PV-diesel-storage for gobi oilfields, reducing diesel fuel consumption and carbon emissions
- Explosion-proof design of AC cabinets, meeting oil and gas zone regulations
- BESS absorbs pumping unit regenerative energy and smooths impacts
- Enhances power supply resilience for remote oil production
Applicable Scenarios and Challenges
Well sites are scattered and the grid is absent, resulting in high diesel transportation and attendance costs; continuous oil production places extremely high demands on power supply continuity.
VGRID System Composition
- Power Conversion System (PCS): Compatible with cyclic impact loads such as pumping units (nodding donkeys), ensuring stable conversion.
- Static Transfer Switch (STS): Switches between diesel generation and the microgrid to prevent power loss during pumping unit startup and shutdown.
- Battery Energy Storage System (BESS): Absorbs regenerative energy from pumping units, smooths cyclic loads, and reduces diesel generation power.
- Energy Management System (EMS): Dispatches according to well site conditions, maximizing PV self-consumption and reducing idle consumption.
- Microgrid AC Cabinet (MPS): Explosion-proof AC cabinet, meeting safety regulations for oil and gas zones.
Core Value
- Reduced diesel consumption and transportation costs
- Improved pumping continuity, reducing losses from well shutdowns
- Lower well site carbon emissions, aligning with energy companies' dual carbon goals
- Unmanned/minimally manned operation with remote O&M
Typical Applications
Suitable for off-grid or weak-grid power supply for desert oilfields, marginal well sites and gathering and transportation stations.

FAQ
How is equipment safety ensured in oilfield areas?
The AC cabinet adopts an explosion-proof design, and the system features arc and leakage current protection, meeting explosion-proof standards for oil and gas areas.
Will the periodic load of the pumping unit damage the battery?
The PCS and BESS work together to absorb regenerative energy and smooth impacts, while the EMS optimizes charging and discharging to extend battery life.
How much diesel can an oilfield microgrid save?
After optimization based on sunlight and load, typical diesel savings are 30–60%, improving with better resources.
Are the devices durable in sandy and high-temperature environments?
Core devices have high IP ratings and are resistant to sand and temperature drift, while remote EMS reduces on-site inspections.
