Pros
I started in the US, then had a chance to work overseas. It was a great way to live in a half-dozen places around the US/world and work with all sorts of people also from around the world. The work was challenging and the job role was always changing with every transfer because even when my title stayed the same, the challenges had to be solved with a now different set of resources in each new location. Compensation while I was in the US was OK at best. While working overseas, I thought it was very generous, but that's from my perspective as someone without a family. To work in some places without one's family would not be for most people.
Cons
This is the oilfield and this is a service company. If you work in a field location, you are always on call. Maybe not explicitly so, but there is always the lurking chance that something will happen like a last-minute client request and then everyone scrambles to please the client. In the end, the lifestyle was my biggest reason for leaving. It was a fun way to spend my 20s gallivanting around the world, but it became far less enjoyable in my 30s.
