the temperatures at depths below about 15,000 feet are high enough (above 275 degrees F) to break hydrocarbon bonds. What remains after these molecular bonds are severed is methane, whose molecule contains only a single carbon atom. For petroleum geologists this is not just a matter of theory, but of repeated and sometimes costly experience: they speak of an oil “window” that exists from roughly 7,500 feet to 15,000 feet, within which temperatures are appropriate for oil formation; look far outside the window, and you will most likely come up with a dry hole or, at best, natural gas only.That paragraph is simply wrong in so many ways it's hard to know where to begin. According to Transocean, they have succesfully drilled oil wells 30,189 feet true vertical depth below the mudline in over 4000 feet of water. This is far below the 15,000 foot limit claimed by Heinberg. And no Mr. Heinberg, hydrocarboon bonds do not break apart below 15,000 feet. That is a lie.
InfoGulf.Com via Offshore Mag: Exploration and Development Below 15,000 feet TVD.
For exploration greater than 15,000 ft TVD on the shelf during the period 2003-2005, 115 wellbores (45 in 2003, 41 in 2004, and 29 in 2005) were drilled by 35 operators.Those wells were drilled at least 2 years ago. We are finding oil much deeper now.
