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.
