National Academy of Sciences completed Oil in the Sea III, its third examination of petroleum inputs into marinewaters worldwide. Although direct comparisons betweenthe 1975, 1985, and 2002 reports are difficult due to use ofdiffering computational techniques, it is clear that petroleum inputs from other than natural sources have decreasedsignificantly over three decades.
Total petroleum input estimates decreased from 43 million barrels per year (MMbbl/yr) to 23 MMbbl/yr between the 1975 and 1985 reports, a 47-percent decrease. In the 2002 report, total petroleum inputs continued to decrease to 9 MMbbl/yr, a 61-percent decrease from the 1985 report estimate (Fig. 1.)
In the 2002 report, worldwide offshore oil and gas development is responsible for only 4 percent of the petroleum in the worlds marine environment (Fig. 2). Offshore oil and gas petroleum development inputs per annum decreased from 0.56 MMbbl in the 1975 report to 0.35 MMbbl in the 1985 and 2002 reports. At the same time, annual offshore oil production increased from 2.3 billion barrels (Bbbl) to 4.6 Bbbl, to 7.0 Bbbl between the three reporting periods. This demonstrates a significant reduction in petroleum inputs per Bbbl of production from offshore oil and gas development between the three reporting periodsfrom 243,000 bbl/Bbbl in the 1975 report, to 76,000 bbl/Bbbl in the 1985 report, to 50,000 bbl/Bbbl in the 2002 reportdespite large increases in production. So, even though worldwide production increased 52 percent, petroleum inputs were approximately the same (0.35 MMbbl per annum) between the 1985 and 2002 reports. The 2002 report also made estimates for North America, where offshore oil and gas development was found to be responsible for only 2 percent of the petroleum inputs in North Americas marine environment.

“The 2002 report also made estimates for
North America, where offshore oil and gas development
was found to be responsible for only 2 percent of the
petroleum inputs in North Americas marine environment.
In the 2002 NRC report**, natural seepage was the largest single source of petroleum in the worldwide marine environment, contributing over 4 MMbbl/yr, 47-percent of total inputs. In North America, natural seepage is the
largest input, contributing 63 percent of total inputs to the marine environment. Municipal and industrial waste is responsible for 12 percent of worldwide petroleum inputs
and 22 percent of petroleum inputs in North American
marine waters. Marine transportation is responsible for
33 percent of worldwide petroleum inputs and only
3 percent of inputs in North American marine waters.”
Some excellent data.
An overwhelming percentage of the oil that is spilled into coastal waters is the result of recreational and commercial shipping, not related to the oil industry. The environmentalists have decided to apply environmental restorative justice to the oil companies, however.
CONOCO PHILLIPS was blamed for a mystery spill in the Puget Sound, which the ship claims they had no part in. The only other vessel in the area at the time of the spill was a state ferry. The state claimed to have tests that proved that the spilled oil was Alaskan oil from the CONOCO ship, but they refused to share the results of the test with the oil company. The state simply dragged out the court case with accompanying bad press, until the oil company capitulated, and paid up.
I bet a big chunk of that decrease is due to increased use of stormwater retention systems
