One confirmed case in Uyo.

ExxonMobil has it's major operations in the shallow waters offshore Akwa-Ibom State with billions of Oil reserves in several fields. Note also that The federal Government owns 60% of all JVO operations in the country.

jahrule:
Oil companies are private ventures and as such the Owners site the head office where ever they feel is suitable for the purpose. Government has little or no power over this issue.

Another thing to consider in location choice of companies is funding, Oil companies would like to have their head office where they could easily contact Banks for funding projects.

Security situation in Niger-delta region is too volatile and no reasonable investors would site Its head office in such region.

Likely defence these companies would put up are the following:
1. Major Investments of these companies are in deep offshore which falls under federal government claims and no state can claim(Oil companies workers can throw more light to this)
2. Security situation would make them to maintain a skeletal offices in ND
3. Government has no right to tell them where to site their offices as non-governmental organizations.

But let`s see what happens.
