Production Control Services Inc. (PCS) recently introduced its new 3DSO Plunger Arrival Sensor for plunger lift wells. Mounted on the surface lubricator, the 3DSO detects the plunger's arrival and activates the controller to the appropriate mode for gas sales or shut-in. The arrival sensor's proprietary technology represents significant improvements in plunger arrival sensing.
Driven by an embedded microprocessor, the 3DSO continually self-calibrates to filter out environmental noise. It uses advanced 3-D technology-like that used in military and navigation applications-to detect the plunger's arrival. By sensing the plunger in three coils in three axes (X, Y and Z), the sensor is able to more accurately detect plunger arrival.
The combination of the microprocessor and 3-D technology enables the 3DSO to detect arrival of the plunger traveling at any speed, even if the plunger is stopped in front of the sensor. This is a major advancement from past technology.
Says Andrew Boldt, vice-president, "By accurately sensing the plunger's arrival every time, the 3DSO allows for optimal plunger lift operations. Because it continually self-calibrates, it offers virtually maintenance-free operation, eliminating operator intervention and production downtime."
PCS does extensive quality control on each sensor. The sensors go through a 25-point, three-axes electronic test, as well as a functionality test. All the test data is stored electronically within the unit, making it easily retrievable.
PCS also designed the 3DSO to ensure long term durability in the field. It features a rugged aluminum housing that won't flex when installed and potted electrical components to protect against harsh weather conditions.
The PCS 3DSO Plunger Arrival Sensor is patent pending.
