Exploration The Cooper Basin and the overlying Eromanga Basin are the most prolific onshore hydrocarbon provinces in Australia . With over 1400 wells drilled to date, more than 70,000km of seismic survey and a pipeline network to established and growing markets the basin is mature in its development but still offers significant exploration potential. Innamincka's current exploration tenements are well located to satisfy reservoir, source and seal criteria for exploration success and are linked on the structure map below.
