Surface Facilities Design Considerations
Objective: To handle CHOPS pilot test wells fluids
To measure produced fluids, gas and sand.
Considerations: Use only proven technology
Design to be as simple as possible
Foamy oil behavior considered (expansion factor: 5) Facilities optimization is not intended at this stage
Facilities design and pump rates based on estimatedstable production of 400 BPD of EHO.
