Shell said that its Leopard Marin discovery offshore Gabon may be a commercial gas field. “Leopard is the first potentially commercial multi-Tcf [trillion cubic ft] find in a new gas play, and I think that is very exciting for us and for the government of Gabon,” said Alastair Milne, Shell vice president of exploration for Sub-Saharan Africa, on 29 October at a conference in Cape Town, South Africa.
