Shale oil extraction Energy estimates that the "ex-situ" processing would be economic at sustained average world oil prices above $54 per barrel and "in-situ" processing would be economic at prices above $35 per barrel. These estimates assume a return rate of 15%. Royal Dutch Shell announced in 2006 that its Shell ICP technology would realize a profit when crude oil prices are higher than $30 per barrel ($190/m), while some technologies at full-scale production assert profitability at oil prices even lower than $20 per barrel ($130/m). To increase the efficiency of oil shale retorting and by this the viability of the shale oil
Imperial Oil (Superfund site) and PCBs. The surface soil is contaminated with heavy metals including chromium, lead, and arsenic, and PCBs. Surface water contained arsenic. On April 15, 2004 - properties adjacent to the Imperial Oil Superfund site in Marlboro Township were the focus of a clean-up. More than 18,000 cubic yards of contaminated sediment and soil were removed from Birch Swamp Brook and adjacent properties between the Imperial Oil site and Texas Road. Restoration of the brook and adjacent properties has followed in phases upon completion of excavation work. The contamination on the site affects the ground water at Englishtown Aquifer, an important
