Advantages
The LiftPlus System:
- 7 year run time in producing SAGD well
- Its positive displacement nature correlates to lowering SOR
- Has very low Operational Cost
- Reduces GHG Emission and Power Consumption
- Is unaffected by temperature
- Can be landed at 90 degrees
- Has infinite turn down ratio
- 1,000 m3/day – 0 capability
- Unaffected by emulsion/gas interference
- Can handle significant sand cut
Environmental
GHG Emission Effect
The GHG Emission Effect can be calculated by applying a C02 emission factor that converts reductions in kilowatt-hours into avoided units of carbon dioxide emissions. The following example uses the industry accepted emission factor that the AVoided Emissions and geneRation Tool (AVERT) has derived.
- Emission Factor
1,640.7 lbs CO2/MWh × (4.536 × 10-4 metric tons/lb) × 0.001 MWh/kWh = 7.44 × 10-4 metric tons CO2/kWh
(AVERT, U.S. national weighted average CO2 marginal emission rate, year 2016 data)
GHG Emission Effect Base Case
One LiftPlus System replacing 1 ESP using 150 HP of continuous electricity
- 150 HP = 111.9 kW…..x 8760 hr/year = 980,244 kWh
- 980,244kWh x 7.44 x 10¯⁴ metric tons of CO₂/kWh = 729.3 metric tons CO₂
- One car emits 6 tons CO₂/year…729.3tons/6 tons/car = 121 cars/year
1 LiftPlus System then to replace 1 ESP is the equivalent of removing 121 cars/year off the street.
- Carbon Credit
- 729.3 metric tons CO₂ = 729.3 Carbon credits
- As per Government of Canada 2023 value of a carbon credit $65/metric tons CO₂ = 729.3 x $65 = $47,400
- Power Savings
- Oilfield Service power cost $0.30/kWh
- 980,244 kWh x $0.30 kWh = $294,000
- Total Savings from 1 Lift Plus System = $47,400 + $294,000 = $341,400/year
LiftPlus System v Gas Lift Comparison
A SAGD operator uses Gas Lift
- Continuously injects 425 Sm3/h gas to produce 250 m³/d total fluid
- Produced emulsion from Gas Lift includes oil, water and gas
- To separate gas from emulsion, condition it for boiler consumption is very costly
The LiftPlus System
- Uses approximately 65% Less gas than Gas Lift to produce 250 m3/d+ total fluid
- Lift Plus System produced emulsion only contains oil and water
- Represents considerable savings to the operator
- Lift Plus System requires significantly less reservoir pressure to produce the same or more produced fluid than Gas Lift
- This yields major savings due to less required steam
- Which inevitably will reduce operators SOR
