Value-driven digital oil field
The objectives of a truly digital oil field (DOF) are maximized recovery, optimized production, improved operational efficiencies, enhanced knowledge base and minimized HSE incidents. The DOF is based on:
1.Smart measurement and control systems in wells (subsurface and surface), networks and facilities;
2.Capture, transmission and integration of real-time data from all assets;
3.Real-time data delivery;
4.Intelligent data processing.
The DOF has several challenges. More than 70% of the wells in the world are still not connected and monitored, and production loss in artificially lifted wells is significant (often more than 10%). Large operational staffs are still required to perform normal daily checks and maintenance on wells. Current technological solutions offered by automation and service companies are frequently too expensive, logistically complex and inefficient, requiring significant maintenance and support.
According to Evinsys, their WellLynx hardware and software platform provides the underlying infrastructure and technologies to enable a true DOF, offering a comprehensive approach that reduces deployment time, cuts maintenance and operational costs, increases uptime, and optimizes production. The WellLynx platform provides real-time data acquisition, data management, time-series history, business intelligence, data-driven analytics, HTML5 visualization and Internet-of-Things managed RTUs.
A comprehensive software and hardware solution, the WellLynx acquires, monitors, manages, analyzes, diagnoses and controls artificial lift assets-—all at a significantly lower cost, compared to conventional SCADA solutions.
The platform is scalable and deployable on public/private clouds or within private networks. The system features simple deployment, and is easy to manage and maintain. Key WellLynx advantages include:
1.Scalable architecture.
2.Built-in time-series historian with unlimited data retention.
3.Rich HTML5 visualization with no client installation requirements.
4.Data-driven, self-learning predictive equipment failure models.
5.ESP diagnostics and analysis to detect gas locking, motor over/under load, plugged intake monitor, oversized pump, pump wear, submergence analysis and tubing leak.
6.Smart caching to improve system performance (can display two years of data history).
7.Multi-tenant capabilities.
8.Multi-level user roles and privileges.
9.Live data streaming with real-time global views and dashboards.
10.Native iOS and Android apps.
11.Built-in reporting engine.
12.Utilizes fully-managed IoT RTU.
13.Reduced communications costs 90% vs. traditional SCADA/MODBUS.
14.Lowest fees in the industry.
WellLynx has been used to manage assets throughout North America and the Middle East, proving its value as a comprehensive DOF solution.
Cloud-hosted monitoring and optimization system
Dover Artificial Lift has introduced its LOOKOUT monitoring and optimization system powered by Theta Oilfield Solutions’ XSPOC software, Fig. 13. This new system delivers users a powerful tool for real-time monitoring, decision making, collaboration and well performance optimization. It’s controlled with a cloud-hosted system for ease of support and maintenance.

The system is tailored to the producer’s specific needs and economics, from simple on/off notifications to active monitoring scenarios targeting key performance indicators. Fostering collaboration and streamlined workflows, the system allows for easy access across a variety of platforms from mobile to desktop; and presents useful information, allowing for gains in production and lengthening lift system run time.
By leveraging the Theta’s XSPOC artificial lift monitoring system, LOOKOUT can be utilized on every form of artificial lift, including ESPs, rod lift, gas lift and others. Operators can pump by exception, where wells that are operating properly can be passed over in lieu of wells that are not operating properly. The system moves beyond alarming and set points, which force users into a reactive monitoring role.
However, by looking at a well model (comparing the ideal performance of both well and equipment, with the actual performance) the system can identify wells that could be operating more efficiently. Further enhancements include daily and monthly reports, all automatically generated, to make the user’s time more effective. The system enhances the way operators can view run life information by categorizing shutdowns into general causes and tracking the root cause of failures.
A key feature is the automatic diagnostics, utilizing the well equipment parameters and its real-time data. By comparing the actual flow from automatically imported well tests against the theoretical flow; diagnostics, such as pump wear or potential tubing leaks, can be proactively determined. Another feature that spans lift-type boundaries is the sizing score, providing the user with an accurate look at well conditions (based on IPR data) and equipment application, indicating if a re-size should occur at the next workover.
By automatically performing these calculations—whether it is exception reports, pump operating points, optimization based on system software diagnostics or well test uploads—the automated nature of the system helps accurately monitor, diagnose, optimize and ultimately increase recovery.
Dover suggests that the power of the system is not only in its automatic operation, but in the collaboration between their artificial lift experts and operators. Company experts will work with users to establish KPI’s, a generate a holistic approach to meeting those KPI’s. Finally, they will conduct weekly meetings, where performance is evaluated and adjusted to meet the operator’s objectives.
