It is not a question of international COMPANIES. It is a question of LOCATION. Let me ask a rhetorical question as an example of what I mean.
How many of the previously producing oil fields such as Nigeria, Saudi Arabia, Iran, Russia, etc are using this technology now?
I suspect that there is a fairly large percentage that are not using the newer technologies.
It certainly isn’t as commonly used, but I suspect it is used in all the countries you mentioned.
Remember, hydraulic fracturing isn’t new. It has been used since the 1940s.
Steerable directional drilling is the newer technology, which combined with hydro fracs, made the shale economical to produce.
Hydro frac tech has advanced significantly and is used more in the US than anywhere else, but it is used world wide and has been for a long time.
For example:
