1. Solution Overview

The oil and gas industry remains the cornerstone of global energy supply. Around the world, from national oil companies to independent exploration and production (E&P) operators, digital transformation is treated as a strategic priority. The maturing of a new generation of connectivity and computing technologies—5G, cloud, and AI—offers a practical path for upgrading aging oilfield infrastructure: digital retrofits can be completed quickly without trenching fiber across remote acreage.

The oilfield is a critical link in the petroleum production chain; its stable operation directly determines output and safety. Building a comprehensive monitoring system covering all well sites, with video surveillance at its core and visualized production management as the driver, is an important step toward higher work-safety standards.

This solution combines automation control, information collection, transmission and processing technologies, remote monitoring and control, wireless information transmission, and big-data transmission and processing. It uses the5G networkas the core transmission channel, with theUSR-G816 5G industrial routerand theNR520X outdoor WiFi6 AP (with 5G NR)as key network terminal devices, to establish a modern, comprehensive monitoring system suited to safe oilfield production. The system consists mainly of wellhead monitoring terminals, 5G network access equipment, and a central management platform. Well-status data collected by the well RTU is sent via 5G to the operator's database servers, enabling production, engineering, and HSE departments to stay informed of well status in a timely manner—shortening fault resolution, raising uptime and output, and keeping personnel away from high-risk areas.

2. Industry Pain Points

2.1 Bottlenecks of Traditional Network Solutions

• Fiber — high deployment cost, long cycles:laying fiber to scattered wellheads means heavy civil-engineering costs, lengthy right-of-way negotiations, and construction safety risks. Many marginal and remote wells never gain remote monitoring at all.
• 4G — insufficient uplink bandwidth:a 4G LTE site typically tops out at roughly 8 Mbps uplink; when multiple HD cameras share the link with telemetry, uplink bandwidth becomes the video bottleneck.
• Bridges — fragile private links:unlicensed/private bridges offer short range, are prone to interference, may require spectrum fees, and degrade severely in bad weather—driving up on-site maintenance costs.

2.2 Operational and Management Challenges

• Diverse — no unified management:field teams run widely differing services—telemetry, RTU management, sensing, broadcast/lighting control, emergency response, local WiFi—with no unified management view.
• Harsh — remote, hostile environments:oilfields span deserts, swamps, basins, and shallow waters; sites are far apart, field staff are scarce, and routine well-rounds are long and hazardous.
• Costly — high labor, low efficiency:rounds, manual data entry, and mechanical start/stop consume large amounts of labor; cross-border "expert travel" is expensive and slow.
• Silos — fragmented systems:legacy systems use incompatible data standards, so headquarters cannot achieve centralized management of regional assets.

3. Construction Objectives

Using 5G industrial routers, outdoor WiFi6 APs (with 5G NR), network cameras, and other monitoring terminals, the solution builds a modern, comprehensive monitoring system that delivers unified management of front-end operations, services, and equipment—meeting upper-level platform requirements for centralized management, tiered viewing, and hierarchical supervision, and enabling multi-level networking and cross-region monitoring. Specific objectives include:

• Full-domain sensing:5G's massive connectivity and low latency seamlessly connect sensors, video surveillance, and equipment monitoring points, breaking down information silos;
• Visualized production management:video-centric HD backhaul and remote visual monitoring of well sites;
• Remote control:low-latency, high-reliability remote start/stop of pumping units and fine-grained valve/pipeline control;
• Proactive early warning:AI-driven fault warning and safety-risk identification—from passive response to proactive prevention;
• Unified platform:a smart oil-and-gas-field data center platform integrating subsystems and interconnecting communications with business systems.

4. Overall Architecture

4.1 System Composition

Built on the chain of "sensing — transmission — analysis — decision," the solution comprises three main parts:wellhead monitoring terminals(sensor assemblies, power modules, RTU acquisition modules),5G network access equipment(USR-G816 per-well access; NR520X area coverage + 5G NR backhaul), and acentral management platform(database servers, production monitoring center, big-data platform and AI engine, deployable on-premises or in the cloud per data-sovereignty requirements).

Data flow:load/pressure/temperature/angular-displacement sensors are aggregated by the RTU and connect to the USR-G816 via TCP/IP; HD cameras connect to the router's Gigabit ports. Data travels over 5G to an MEC edge node (isolated from public traffic) or directly to the operator's core network per the agreed connection model. In areas requiring regional coverage, the NR520X outdoor WiFi6 AP provides access, backhauling via its built-in 5G module—everything ultimately converging at the production monitoring center.

5. System Functions

• Real-time data acquisition and transmission:collects pressure, temperature, flow, dynamometer data, three-phase voltage/current, power, daily consumption, etc., and transmits it over 5G at low latency.
• HD video surveillance backhaul:5G bandwidth sustains stable multi-camera HD transmission versus 4G's sub-8 Mbps uplink ceiling.
• Alarm and safety interlocking:alarms for shutdowns, out-of-limit parameters, rod parting/sticking; restricted-zone intrusion alerts forwarded to the responsible center; live big-screen views for emergency command.
• Remote control and dispatching:remote load-over-limit shutdown, scheduled start, parameter adjustment, valve switching; thresholds and configs set remotely.
• Intelligent early warning and predictive maintenance:fault warning before failures occur; AI video analysis detects missing helmets, PPE violations, fire, leaks, and intrusions for unattended alarming.
• Data management and analysis:power-loss data protection, start/stop time accumulation, real-time and historical trends of dynamometer/current/power/temperature/pressure.
• Static data management:manages pump model, motor config, well number, stroke, alarm limits, well condition; add/delete/edit wells.
• Protective design and anti-theft monitoring:cross-analysis of pressure-gauge data to deter theft; all links protected by VPN encrypted tunnels.
