The advantages of IAR's lifTER
Efficient Patented Algorithms
IAR's patented algorithms can increase the production of
the well. Simple Operation
All system parameters are entered through a menu driven text
user interface. Environmentally Sealed
All electronics are sealed in a double sealed stainless steel or
standard fiberglass enclosure. All connections are made externally
using the supplied cable. Historical Data
Records data for 10 trip times, total arrivals, total no arrivals,
total on time, and total off time. Smart System
The lifTER time-based Smart System (Patent# 6,241,014) can be
programmed to adjust time cycles to meet an optimum plunger travel
time. Differential Pressure System
The pressure-based lifTER (Patent# 5,957,200) can optimize well
production using differential pressure to calculate when the well has
sufficient energy to move the column of fluid in the tubing. The set
point is based on the tubing pressure equaling a user set percentage of casing
pressure. Pressure Switches The time-base unit can monitor pressure switch gauges for high and low casing pressure, and sales line pressure. Pressure Transmitters A pressure-based lifTER can monitor up to three transmitters for casing, tubing, and sales line pressure. Pressure Trending Trend pressures for up to 45 days. Gas Flow Monitoring The unit can monitor a Gas Flow Computer 0-5V or 1-5V output for critical rate set-point during and Afterflow Cycle. Remote Operation The lifTER has telecommunications options including cellular telephone, radio, and satellite. Hazardous Locations lifTER can be ordered with the Class I Division 2 certified option.
Plunger lift technology is an artifical lift mode with low intial expenditures, simple installation, and low annual maintenance.
It eliminates paraffin, asphaltene, and scale deposition in downhole tubing.
The well's own energy powers the system thus eliminating the high cost of external sources.
Candidates for plunger lift technology are high GLR (Gas-Liquid-Ratio) and gas interference rod pumped wells.
Well production is maintained to economic depletion.
