In 2011 oil was discovered at Surprise within the Ordovician lower Stairway Sandstone at a depth of 2,500 metres sub-surface. This discovery extends the Horn Valley Siltstone hydrocarbon fairway 160 km west of the Mereenie Oil and Gas Field. Surprise is an anticlinal trap situated on one of many northwest plunging trend. The trap formed as the result of compression and associated salt tectonism in the underlying Neoproterozoic section.
