Gulf Oil Spill: 210,00 Gallons of Oil a Day for the Next Three Months

BP Plans to Drill a Relief Well to Siphon Oil from the Original Wellhead

Dave Williams
Looks like the situation in the Gulf is going to continue awful for a long time. Here's what BP's plans are, shown in the accompanying image. The underwater robots (ROVs) can't get the blowout preventer to close. The blowout preventer is essentially a gate closure at the wellhead designed to block the flow of oil from the reservoir in the event that what happened in the Gulf a month ago happened.

This is a sad graphic. You can see the crumpled mass of the oil rig on the ocean floor, 5,000' below the gulf's surface. We see also the lengthy pipe that rose from the wellhead up through 5,000' of ocean to the oil rig on the surface.

Current plans are to dig a relief well to siphon the flow of oil from from the wellhead to a relief pipe and second oil rig. Set-up and completion will take eight to twelve weeks. First there's 5'000 of ocean depth to deal with. Then 18,000' of sedimentary depth beneath the ocean floor. Then a long cant sideways, beneath the ocean floor, to reach the well head and create a siphon.
