What makes the oil companies think they can produce oil and gas safely in the very harsh world of the Arctic oceans? They cannot do in the Gulf of Mexico, or the Niger River delta, or anywhere else for that matter.
This article is authored by a former employee of Shell Oil. His identify and background is known to us.
Back in the early mid-1980s Shell Oil began to take a serious look at the hydrocarbon production potential of the Chukchi Sea. They formed an operating division and staffed it with management, albeit with no staff, except secretarial support for the managers. (These guys were referred to managers without portfolio).
Shells exploration and production research division began to investigate the regions of the Chukchi Sea where potential lease sales were likely to occur. Of interest were the basic oceanographic parameters; water depths, under topography, sea floor surface geology, ice pack characteristics, etc. The basic surveys revealed some interesting results. The sea flow was basically covered fairly deeply with soft sediment (marine mud) but the topography was highly unusual. Acoustic mapping revealed an ocean bottom that was scarred by all sorts of crisscrossing trenches from a meter or so in depth, to almost 20 meters in depth.
