38 | July 2018 | ARTIFICIAL LIFT: TECHNOLOGY SHOWCASE Increase ESP runlife in high solid content wells Producing signifi cant volumes of abrasive sand, iron sulfate and other solids with electric submers- ible pumps (ESPs) presents challenges, which can compromise system runlife. In standard construc- tions, excessive abrasives can wear pumps quickly, reduce performance and cause premature fail- ures. To provide advanced wear protection with- out sacrifi cing pump effi ciency, Valiant Artifi cial Lift Solutions offers abrasion-resistant modular (ARM) pumps featuring robust tungsten carbide bearings for enhanced radial support. Since pump down thrust is carried at each ARM bearing place- ment, no impeller or diffuser down-thrust load is transferred to the ESP's seal section, thus rais- ing the total thrust load capacity of the ESP and allowing deeper setting depths. Additionally, Val- iant's ARM bearing sets feature a system of slots and grooves with unique geometry, proven in the fi eld to allow suffi cient fl ow of solids through and around the sleeve and bushing, thus pre- venting accelerated wear, heat buildup and shaft breakage associ- ated with sand accumu- lation in these spaces. Unit boosts productivity with a longer stroke The latest Weather- ford Rotaflex long- stroke pumping unit helps operators transition to high-performance rod lift and eliminate the need for intermediate lift methods. The Rotafl ex unit boosts productivity with a longer stroke, more complete barrel fi llage and less wear on surface and downhole equipment. Even in deep, high-angle or high gas-to- liquids wells, the latest Rotafl ex unit was redesigned to further increase uptime, reduce the total cost of ownership and streamline maintenance. With stroke lengths up to 366 in., the unit increases system effi - ciency and energy savings, substantially lengthens sucker-rod and downhole-pump longevity, and reduces cycles, reversals and the risk of downhole failure. The design simplifi es inspections and repairs, encloses moving parts and offers easy access to major components. Autonomous rod pumping issue detection, resolution Zedi's SilverJack Artifi cial Lift solution provides advanced rod pumping technology to the upstream oil and gas industry. The SilverJack portfolio con- sists of several product confi gurations spanning a wide range of oil and gas wells from low to very high producers. Features such as remote access, fl exible alarming, precise rodstring control and advanced optimization capabilities have helped producers lower their costs while realizing their production potential. With the introduction of a new algorithm, the SilverJack artifi cial lift system can autonomously detect and resolve common downhole rod pumping issues such as a stuck standing or traveling valve and gas lock. The unique algorithm uses operating parameters, such as the dynamometer card, to detect and identify issues then autonomously make adjust- ments to the stroke profi le in an attempt to resolve the issue. By addressing issues in near real time, this new capability has the potential to signifi cantly enhance a well's production. ■ The slot and groove geometry on this bearing set allows ESP systems to operate effi ciently in high solids production.
