CVX have certainly tried things when others have failed or withdrawn.
One example was the foray into Eastern Europe to try to exploit shale gas in a number of countries.
This obviously did not work out even with JJ guiding and DM muscling things on.
Why?
No actual reserves in place?
No proper consideration of political, legal and environmental nuances outside the US?
Another question - why do we continue to spend money on 'evaluating' potential MCP's which were not economically viable at $100/bbl let alone at current?
