Don't forget Exxon pitched Guyana everywhere........no takers in super Majors, ended up with Hess and Chinese...what a drill success story for them.
The only thing wrong with Tullow walking away...should of done it years sooner as they were doing SFA.
At one point there was talk of Indian participation offshore Guyana as a less troublesome location than Middle East/Russia. Perhaps cheaper oil supplies in middle of ocean ship-ship in middle of night right now than drilling risk.
