SAGD Optimization
Challenges:
- Constrained production on oil handling and steam production
- Wells must be shifted in time in order to fit within these constraints
A flow schematic is easily created in WellSpring to represent the field wells and facilities
Individual constraints can be added at each of the facility nodes
After the optimization, the field is producing within the facility constraints
This model can then be used to compare Steam Oil Rates (SOR) sensitivities
•We can create a second scenario with an SOR of 3.2 (32,000 Bbl/d steam) and then compare the production and economics with the original SOR 3.4 case.
The plot below shows the SOR 3.2 case subtracted from the SOR 3.4 case. Steam requirements are accelerated, as is oil production
