The Melbourne-based midcap is the second oil and gas company to make the list in the past two weeks, behind new Timor Sea producer AED Oil.
Nexus has three main projects in its asset portfolio – the Longtom gas field in Bass Strait and the Crux and Echuca Shoals gas-condensate fields offshore northwest Australia.
Maiden cashflow and production is expected in the second half of 2008 when Nexus brings Longtom online.
