Page 36 of 51 | July 2018 | 35 ARTIFICIAL LIFT: TECHNOLOGY SHOWCASE operation of the plunger lift equipment. The design also enables installation that can be accomplished in under one hour. The assembly can be reconfigured to fit in the spacing where the existing API flow tee and wing valve or API flow block and wing valve are located with a few easy adjustments. This design also eliminates expensive highline modifications as well as reduces field and engineering costs and extended downtime. This flexibility minimizes loca- tion flowline modifications and the extra costs that typically come with the modifications. The design is fully engineered, 100% inspected and 100% tested. Fire safe valves, steel-on-steel primary connection seals, and 3,000-psi and 5,000-psi w.p designs are available. Using kinetic energy for plunger lift safety and maintenance The Sasquatch plunger velocity sensor is a new innovation that measures surface velocity of the plunger arrival. This gives an accurate velocity of the plunger just before it strikes the anvil inside the lubricator. Sasquatch uses the surface velocity and mass of the plunger to calculate the kinetic energy of each plunger arrival in real time. This is compared to user-defined thresholds for hard and dangerous hits, resulting in alarms that can be used to shut down operation of the plunger well to protect equip- ment. Kinetic energy of hard and dangerous hits is summed over time to predict spring wear. These fea- tures allow operators to make use of kinetic energy ratings that are stamped on lubricators as part of the new American Petroleum Institute 11 PL standard. Injection pressure operated gas-lift valve Flowco Production Solutions has developed a line of high-pressure (HP) gas-lift equipment that solves the issue of equipment failure at higher reservoir pressures. As operators encounter higher reservoir pressures or decide to employ higher discharge com- pression to lift deeper and maximize production, the pressure ratings of common gas-lift equipment can be exceeded and lead to failure. The TPH-1.0 achieves valve test rack opening pressures of 3,000- plus psi and is designed to withstand external pres- sures of up to 10,000 psi. To further resolve these issues in conventional or gas-lift applications, the TPH-1.0 system, when coupled with Flowco's 10K HP Check Valve and Tubing Retrievable 10K HP Mandrel, meets the challenges of today's HP land applications. The HP line also is available in wireline retrievable models. The Dual Valve assembly "Inclusive Modular" design focuses on reducing the extensive cost of facility modification to accommodate the installation of a plunger lift lubricator.
