This is Central Processing Facility 1(CPF1), where the multi-phase (water, oil, gas) liquids from the wells are separated. The water and natural gas are mostly re-injected down hole, although some natural gas is processed to provide power for compressors and such. The processed crude is sent from CPF1 to Pump Station 1 of the Trans-Alaska Pipeline.
This is an aerial view of the Milne Point Production Center. It functions like a smaller version of CPF1.
Here’s a drill site at Kuparuk. The well houses are the vertical row of orange boxes in the center of the photo. The well lines run from the well houses to the manifold building, the large orange box. From there the multi-phase liquids head off to the CPF for processing.
Here’s another shot at Kuparuk, taken later in the year. The flare is used to burn off excess gas “burps” in the system to prevent over pressurization of the system and a potential explosion. Better to burn off the transient pressure increases than risk the place going “BOOM!”.
