RECO. Man oh Man, Dave, I admire your agnosticism and strategic discipline but at this point I personally could not imagine going long on RECO though I have been watching the strong bounce backs after sell-offs.
Eco (Atlantic) on the other hand strikes me as both a decent trader and OK holder if one screws up and fails to sell out in the heat. It has assets in popular offshores basins, some geographic diversification, good partners and a decent track record of raising capital.
Africa Energy (AFE.v) is another option that has sold off but I have not looked at carefully enough.
In the Africa offshore space, Africa Oil (AOI.to) is the conservative bet but I don't see it providing a sexy tax loss opportunity.
Near term, I reckon both CGX Energy and Frontera Energy have more potential upside. Wei-1 will get drilled even if the Noble Discoverer has been detained by Shell offshore T&T.
