Technical Power generation in an Oil field - requirement
I’m trying to better understand how power generation capacity is determined for an oil production field. How do you determine the right power generation capacity for an oil field?
Power demand changes over the life of a field, and so can the availability of fuel gas.
This makes me curious about how designers balance:
a) Peak electrical demand
b) Early, mid, and late field life operating cases
c) Fuel gas availability
d) Generation redundancy and availability
Which field life scenario ultimately governs the sizing of the power generation system?
And is the peak demand generally expected during early life, mid-life, or late life, or is there no typical answer?
I’d appreciate insights from those with experience in offshore power systems, process design, or field development.
