Warri is Good
If you're going to the Chevron base working on the 412, it's very good. Security is good, you live just over the road from the helicopter base and even for that there's a security convoy. Housing is excellent with a swimming pool, tennis courts and gymnasium. Good food and a bar. The rooms are very nice with satellite TV and cooking facilities and there's even a small supermarket on the base.
If you're going to Shell to work on the EC155, you'll live on a large secure camp which also has swimming pool and tennis courts, plus a golf course.
Overall, Warri with Bristow is one of the better places to work in Nigeria
