"Cornea-1, drilled in 1997, was reported to have found from 600 million barrels of oil (MMBO) to 2.6 billion barrels of oil (BBO) in place (Williamson, 1997; DPIE, 1998). This discovery is considered to be the first commercially producible oil in the Browse Basin. It confirms a new play trend located along the far eastern edge of the basin that was first indicated by Gwydion-1 drilled in 1995. The Cornea discovery proves that very large volumes of oil have been generated in the mature central portions of the basin and it confirms there has been long-range migration and charge. Gwydion-1 tested a compaction structure draped over a basement high similar to Cornea and located roughly along the same trend. Both discoveries are visible as seismic anomalies and hydrocarbons are detected in the water column at Cornea."
