New iPhone and iPad Interface Let Users Monitor Their Wells Anywhere, Anytime
The new iGMC application from Unico makes accessing well information from your iPhone or iPad a breeze. The app works in conjunction with Unico’s GMC® Global Monitoring and Control System, which wirelessly collects data from any number of wells and delivers around-the-clock real-time monitoring, analysis, automated reporting, and alarm notification.
Previously, the GMC® system was accessible only through a Web browser. The new iGMC app provides dedicated access from the iPhone and iPad handheld mobile devices from Apple, Inc. The app uses the same secure data server and back-end infrastructure that powers the browser-based system but tailors the presentation for a touch-driven interface. Whether you’re at your desk, in the field, or just having lunch, all of the data from all of your wells around the globe is at your fingertips. Well status and the latest analysis charts are available at a glance, while more in-depth informationsuch as parameter and gauge trends and charts, comprehensive well reports, data archives, and event historyis just a few touches away. The convenient interface makes it easy to keep tabs on operations wherever and whenever you want.
You can download the Unico iGMC app from the Apple iTunes store free of charge, although a subscription is required to use the GMC® service. The iGMC app is a universal application that works on both the iPhone and iPad devices. To get an account, please contact your Unico representative.

New Office Opened in Four Corners Region
Unico has opened an office in Durango, Colorado, to service customers in the Four Corners areathe region surrounding the intersection of the states of Colorado, New Mexico, Arizona, and Utah.
Heading the new expansion is Jordan Hanson, who has relocated from our corporate headquarters in Franksville, Wisconsin. Jordan previously provided daily supervision and leadership for the manufacturing process for many of our artificial-lift products, including the LRP® Linear Rod Pumps and CRP® Crank Rod Pumps, among others. Though he will be missed in his production role, his dedication and experience with these units are welcome additions to our outside market support team. He reports to division sales manager Christopher Schmidt.
As regional manager for the southwestern United States, Jordan will be assisting our partners and producers with sales, troubleshooting, and repair as well as establishing a warehouse and inventory to support the region more effectively.
Please welcome Jordan to his new role and to the Four Corners region. Jordan can be reached at 262.488.0240.

Remotely Troubleshooting Sucker-Rod Pump Valve Problems with the GMC® System
by Ron Peterson development engineer
Valve problems can be hard to pinpoint, especially if they are intermittent. A sticky standing or traveling valve may not make itself known until there's a measurable drop in production with time. Then begins the hunt to find the cause. Unico’s GMC® remote telemetry system gives operators and well analysts the ability to quickly and easily diagnose such problems early so they can be quickly corrected.
In the example below, a well in Illinois using a Unico LRP® Linear Rod Pump system had a history of troubles with sucking in sand and silt. The operator was alerted to a pumping problem by an unexpected drop in inferred production as shown on the main GMC® screen. Double-checking the fluid flow rate trend analysis (below) confirmed that the flow rate had dropped to zero barrels per day.
The problem was investigated further by examining the stored dynamometer plots (below). The downhole plot shows that the pump load is flat-lined at its theoretical maximum. This suggests that the pump is raising and lowering the weight of the rod plus the fluid, indicating that the standing valve is stuck open. Typically, this is remedied by flushing the pump to remove debris. In this case, the problem resolved itself over time.
The next day, the same well experienced a stuck traveling valve. In this case, the downhole pump load is flat-lined at zero, indicating that there’s no load on the plunger and only the weight of the rod is being raised and lowered. This signals that the traveling valve is stuck opena problem that can be solved by tagging the pump periodically or by flushing out the pump. Incidentally, Unico’s LRP® lift systems incorporate a hands-free automatic tagging feature that can be triggered remotely to loosen debris without ever having to dispatch a crew.
Detecting stuck valves is just one of the many ways the GMC® system is an effective aid to troubleshooting pumping system problems remotely. We will be examining others in future issues of Solutions.
