Interesting data:

How representative these numbers are for a lot of the offshore areas our gov’t has restricted development of, I do not know.
How much of these costs are due to over-gov’t and the green agenda I also don’t know - maybe someone has some estimates. For example, Keystone was supposed to send light shale oil to Canada to mix with their tar sands heavy product to make it pipe-able back to the US to be refined. (Also the mix can be adjusted to better suit the refineries.)
That’s “operating”. That is, break even to keep pumping an existing well.
Wells deplete and dry up and must be re-drilled.
The needed price to replace wells is much more like $90, although the Permian Basin is lower.
