Document Summary
Deep water = > 400m below the sea surface. The oil is deeply buried, beneath formations known to be prone to earthquakes. They are surrounded by canyons, ocean ridges and active mud volcanoes. Temperatures on the sea floor are near freezing, while oil reserves can be up to 400 degrees fahrenheit. The first drill rig was brought to a halt by hurricane ida after just a month. After this, a drill pipe got stuck in the borehole, as did a tool sent down to find the stuck section. This led to bp being 6 weeks behind schedule, which was costing them over sh. 5 million per day. The focus on staying on schedule and saving money led to the urgency to drill faster: describe the specific incident that occurred on april 20, 2010 which led to the explosion. A large gas bubble found its way into the casing and shot straight up.
