Sasquatch is the next stage in the evolution of plunger detection. The unique design of Sasquatch is based on the proven technology behind the Cyclops® plunger arrival sensor.
Repetitive fast plungers are a common problem in plunger lift causing costly damage to equipment and production downtime. A lubricator breach can lead to incident reports, spills and injuries. Hoping to avoid these issues, producers replace lubricator springs and plungers on a regular basis. In many cases, perfectly good equipment is being prematurely discarded, leading to wasted labor and equipment costs. Sasquatch gives you the power to reduce or even prevent these occurrences and prolongs the life of wellhead equipment by enabling detection of fast plungers long before they cause problems.
As the first ever plunger velocity sensor, not only will Sasquatch signal that a plunger has arrived, velocity of the plunger will be measured at surface. A patented algorithm quickly and accurately measures the surface velocity of a plunger as it travels by the sensor. If plunger mass is provided, Sasquatch can calculate kinetic energy, then alarm on a set number of hard hits or a single dangerous hit. Kinetic energy can also be used to alarm on exceeding a total amount of kinetic energy (spring wear) or total number of hard hits.
Sasquatch acts as a Modbus Slave, with an integrated RS-485 communications port. No SCADA? No problem! Up to 120 arrivals with date, time and velocity information are available to download right from the unit on-site. For best results, use Sasquatch in conjunction with the ALiEn²’s patented Adaptive Seeking Velocity Optimization™ to improve production. This intuitive algorithm reduces the need for operator intervention by making adjustments that are proportional to the current flow/close time.
ETC’s innovative line of plunger sensors provide advantages that no other plunger sensors offer, such as the ability to adjust sensitivity, upgrade software, and use real time data to troubleshoot problematic wells.
