ELift™:  A SAGD Two-stage Artificial Lift System

ELift™ is a two-stage lift system designed to meet all of the highly demanding requirements of low pressure SAGD artificial lift and provide excellent steam trap control …read more (see publication: Artificial Lift, A Major Unresolved Issue for SAGD)


New Recommendation:
Concentric Configuration for ELift


ELift has a  basic implementation with key features plus a number of implementation options  available.
 

    Basic ELift Implementation in a SAGD Well


There are a number of benefits in implementing ELift:

Improved Recovery Performance

Pump Benefits

Operational Benefits

Cost Savings

Kyoto Compliance


An assessment of SAGD Steam-Trap Subcool Issues shows that low subcool values are vital, especially at lower pressures, for improved recovery performance and maximum steam chamber development.

Lower pressures magnify problems for standard bottom-hole pump configurations.

 

ELift has been field demonstrated.

View a variety of online ELift example simulations with detailed results high-lighting ELift performances.

Lower Pressure SAGD

Read the following for more information regarding technologies that form the basis of the ELift artificial lift system.

  SAGD Expertise

Dr. Ken Kisman provides expertise for the SAGD industry.

 

 

  ELift - Artificial Lift

ELift™ provides maximum steam chamber development along the entire length of each well pair, resulting in improved recovery performance due to excellent steam trap control with low subcool values.

 

 

  ELift Reduces the Required Facilities

- Reduced bottom-hole pump rate.

- Surface liquid separation facilities reduced by up to 10%.

- Reduction in surface steam and production facilities due to low SOR and WOR at low pressures.
