I have never seen a graph like this. There should be a label for what kind of graph this is or else a clearer explanation of how to read all the parts. It's very nice work but it requires some guidance on reading it.

Apologies. It is simply a 3-d graphic of a 3-d pie but the data is just a regular flat pie chart. A bit confusing to read. It says that the picture was extracted from a PDF but the fixed link I put to the BP report, does not have this graphic included. If the link broke and BP replaced the report with a PDF that did not include this confusing graphic, that might make sense.
