Drilling for oil ?
September 9th, 2008On last weeks show, I was commenting that I was opposed to any further drilling in the Gulf. One of my reasons was the potential for spills and the damage that would do to our economy. And considering any gain in fighting our “dependence” would be at least 8 years down the road and minimal at best.
A caller corrected me in saying that spills were a very small if non existent threat.
His call spurred me to investigate further and I’ve copied all my findings below.
The short story is, he was correct. The “rest of the story” is, virtually the only thing that hasn’t caused the millions of gallons of fuel spilled into the gulf are oil rigs.
I’m still opposed to drilling in the gulf, only now I won’t use that reason.

Hurricanes Destroyed 109 Oil Platforms: US Government
“We had altogether, with both of the hurricanes, about 2,900 platforms that were in the path of the hurricanes,” Interior Secretary Gale Norton said. |

Hurricanes Katrina and Rita destroyed 109 oil platforms and five drilling rigs in the Gulf of Mexico, but only a small portion of production will be lost for good, the US government said Tuesday. Rita accounted for most of the damage in a region that ordinarily produces nearly one-third of

Hurricane Gustav: How Hurricanes Threaten Offshore Drilling and the Environment
In 2005, Hurricanes Katrina and Rita destroyed 113 offshore oil and gas platforms, damaged 457 oil and gas pipelines, overturned storage tanks at onshore refineries, and spilled 9 million gallons of oil—nearly as much as the 10.8 million gallons spilled into
Anticipating the potential damage, and drawing on lessons learned from the destruction caused by Hurricanes Katrina and Rita, oil and gas company officials locked down their offshore platforms and halted production at their refineries. Unfortunately, Hurricane Gustav is on track to cut a swath through approximately 4,000 offshore oil and gas platforms in the
Ironically, one of the most persistent myths skewing the debate over whether to open U.S. coastal waters to more offshore drilling is that offshore oil platforms, along with their supporting pipelines and onshore refineries, are at no great risk from hurricanes, earthquakes, or other heavy weather and seismic events. As proof, the people who perpetuate this myth often point to Hurricanes Katrina and Rita, and oil and gas facilities in the
“Wells and platforms were shut down before the storm, so leakage from those facilities was minimal. Pipelines were shut down too. But what the officials failed to mention is they don’t require industry to “purge” pipelines before a severe storm - so they were probably still loaded with oil, gas or liquid gas condensate. Any section of pipeline that was breached leaked all of that product into the Gulf within hours of the storm. That’s what we think accounts for the widespread slicks seen on the imagery from September 1 and 2, covering hundreds of square miles and obviously emanating from many points of origin. These slicks dispersed after several days of high winds offshore, as shown by our followup imagery taken on September 12, but a few problems remained as evidenced by ongoing leaks from wrecked platforms. ”

The Effects of Discharges of Drill Cuttings
If oil and gas exploration rigs and production installations are allowed to dump drilling wastes unchecked, the effects on marine life can be extensive and biologically significant. Over the past 40 years in the UK and Norwegian sectors of the North Sea, for example, about 1.3 million cubic metres of drill cuttings and associated wastes have built up on the seabed in 102 individual “cuttings piles” with an estimated mass of from 2 to 2.5 million tonnes. The largest pile contains over 66,000m3 of material and weighs about 100,000 tonnes ( For fuller details, see: Det Norske Veritas. 2000. op. cit.; and Grant, A. 2000. Toxicity and Environmental Risk Assessment of Drill Cuttings Piles.
Although the discharge of cuttings contaminated with OBMs and SBMs is now effectively banned, or about to be banned, in
While the areas of affected seabed are much smaller where only water-based muds have been used (Grant, A. 2000. ibid.; and Olsgard, F., and Gray, J.S. 1995. A comprehensive analysis of the effects of offshore oil and gas exploration and production on the benthic communities of the Norwegian continental shelf. Marine Ecology Progress Series 122: 277-306.), the ecological effects are still significant because, as discussed above, WBM drilling wastes may contain free oil, dissolved aromatic hydrocarbons, heavy metals, radionucleides (Minerals such as barite and bentonite, and some drilling chemicals, may contain minute amounts of radium. For example, in 1999 a cargo of 800 tonnes of calcium chloride powder, destined for use in
