Shell Nigeria recovers 95% spilled oil? Pardon my skepticism

Shell Nigeria recovers 95% spilled oil (Aug 20, 2018)

My colleague Darry MacMahon wrote – Pardon my skepticism, but how would they know? I’m making some assumptions here, based on typical oil industry and pipeline operation practice.

If you come up with a ratio number, like 95%, you need two underlying numbers: the amount recovered and the amount actually spilled.

The people doing the clean-up might have a reasonable number on how much they picked up. That number will likely be a little inflated, as they will also likely have picked up some water and small debris as part of the clean-up. Big vacuum units are not good at discriminating between oil and other things in and around the oil. So, the numerator is likely overstated. read more and its sister websites,,,,, and are all owned by John Donovan. There is also a Wikipedia article.
