Largest marine oil spill in history
Oil gushed for 86 days into the ocean

Firefighters combat the fire
Energy companies now focused on oil and gas resources in deeper, more difficult waters of 1,000 feet and beyond.
The Gulf of Mexico is peppered with thousands of oil platforms
Remotely controlled robots; 3&4-D seismic info.; 1 billion dollars per deep oil field.
2. Fixed platform
3. Jackup rig
5. Drill ship
6. Tension leg platform.
An immediate challenge is to gain a better understanding of the deepwater environment and the issues that arise from operating at these depths.

Dome to capture and recover escaping oil
Oil captured and pumped one mile to oil tanker on surface of water
All failed or were ineffective
Blow out preventer
five stories, 380 tons
3 stages -
1. Cap was placed on top of the BOP after a 20 foot pair of shears had cut the riser from the BOP, stopping the oil for the first time. June 3, 2010
2. Relief well was completed at a depth of 17,977 feet. After 2 failed attempts. Sept. 15, 2010
3. Cement was pumped into the well to permanently seal it.
Relief well: a well drilled to intersect an oil or gas well that has undergone a blowout.
Fish, shrimp, oysters could not be eaten, or sold
Impact from the oil spill
Provides 50% of the air you breathe
Biodiversity and future life
can help make the USE of petroleum go away……….
Educate yourself on wise energy consumption
Make choices that lessen the use of oil – transportation, idling motor, conservation, efficiency, etc.
Know the difference between good science and “junk science”
Be prepared to vote with an informed opinion on energy choices
