Opis izmjene

This image depicts an early oil field exploitation in Pennsylvania, around 1862. The two wells shown are the Phillips well and the Woodford well, both among the most productive of the time. Note the small distance between them. At the foreground appear wooden barrels in which the crude was stored, explaining why oil is still measured in "barrels". Note the barrel size was not standardized yet : various size of barrels can be noticed.

Cette image montre un des premiers champs de pétrole exploités en Pennsylvannie, vers 1862. Les deux puits visibles sont le Phillips well et le Woodford well, tout deux comptant parmi les puits les plus productifs du monde à l'époque. Notez la distance dérisoire les séparant. En arrière-plan, on remarque les tonneaux de bois dans lesquels le brut était stocké, expliquant pourquoi le pétrole est encore aujourd'hui mesuré en "barrils". La taille des barrils n'était pas encore uniformisée, en observant attentivement on remarque différentes tailles.
