I asked because I work for the big Anglo Dutch Company in a pretty senior role and in a position to help if you worked for that company. Since you do not, my only advice to you is, if your wife has family in NL and you are Dutch, I would move your wife and family back to NL and get her as far away from OM as geographically possible. If, in the future, she again suggests moving back to South America, you tell her the answer is no, it is non-negotiable and if she wants to remain married to you, she has to forego moving to South America - it is a consequence of her actions. Anywhere even on the same continent as OM is too close.
