Power Generation
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…

Electric Heat Tracing—Pipe-Wall Temperature Vs. Actual Fluid Temperatu
Hello I would appreciate clarification on what “process temperature maintenance” means when specifying electric heat tracing. Consider a water-saturated gas entering a pipe at 35°C, with a water dew point of 35°C at the inlet pressure. If the specified heat-tracing maintenance…
