Giyera was captured in GT Agrochemical, Michigan. The Zephyr One was then taken to investigate the Schoonebek Oil Field, and just when they were approaching Dutch airspace, Giyera forced a landing inside what it has been called until now "Gideon Malick's Headquarters".

So, we'll wait until the episode airs, but everything indicates that the headquarters and the oil field are the same location.
