I would need something like ek.get_rics(oil refineries, region="world") which would output a list of rics of all oil refineries in the world.
I tried using the interactive oil map, made a layer on refineries and export that to excel. Yes, you get a list of tickers, but only those currently zoomed on the map. And if you zoom out to get the world, you get a summarizing table containing the # of OR's per continent/country.
