Refineries in Nigeria were build in den days military administrators, these refineries were situated in Kaduna, Delta, and Rivers state respectively,. They operated with out interruption for decades during the military regimes now they are all dilapidated and are begging for resuscitation.
Our Nigerian refineries are not functioning and are left abandoned is not because Nigeria, doesn't have the resources to repair them or they don't have the resources to build new ones. The refineries are left dilapidated because people in high places wants it to be so, the people that are benefiting from fuel subsidy and importation of refined petroleum products will never allow the refineries to work. Nothing is working in the country, these sets of wicked people that have also not allowed us to have steady electricity power supply will will never be happy to see any meaningful things to work in Nigeria, because they are gaining from the dilapidations.
Dangote, refinary is an evidence that we have highly placed wicked individuals that doesn't want any refinary to function Nigeria, imagine having that magnitude of a refinary that can produce finished products that can serve the whole country but they wouldn't let it to function because they won't be able to import fuel again. The uptimal functioning of Dangote, refinary will make them not to import fuel into the country again and be getting richer so they'll rather have a country that will totally depend on importation to enrich themselves.
You rightly said it all, how can the refineries work when the president and his cabal all owns an oil wellthey use to export crude. If the refineries is functioning they won't make money so they will fight anyone trying to make a good life for Nigerians, its unfortunate we have evil and wicked men in power that doesn't care about the generations to come, they are only interested in the present and what they will steal from the National treasury. Africa leaders are all useless, Nigeria in particular has no hope for the future generations we keep voting people who are not worthy of truth.
See how they are frustrating Dangote Refinery, they won't let it function. Dangote is regretting making such investment in Nigeria right now. Tinubu is busy buying more oil company, he just bought Agrip oil company. So it be hard for us to have a working Refinery in Nigeria.
