Crude oil floating in the ocean used to be a big nuisance in parts of California. It is a natural phenomenon, created by oil deposits on the ocean floor leaking into the environment. Santa Barbara was particularly famous for it.
Extraction of that oil via commercial wells greatly reduced the natural seepage, which is why there is so little crude oil floating in that ocean water today. Oil drilling actually made the water cleaner.
So you’re saying drilling destroyed crude oil’s natural habitat?
To me this "drilling is good for the environment narrative" sounded a bit misleading.
And not far down the rabbit whole one finds: The author of the study often cited by oil companies for above narrative, felt impelled to publish a clarifying statement: https://luyendyk.faculty.geol.ucsb.edu/Seeps%20pubs/Luyendyk...
Maybe stricter guidelines against operational "routine" spills led to a reduction of the sticky spots, plausible?
Per NOAA and USGS, ~20 million liters of crude oil naturally seeps into that part of the California ocean each year. That is more crude oil each year than the worst oil spill in California history[0].
You are projecting your biases. There was no "drilling is good for the environment" narrative. I was recounting an interesting fact about the environment there.
Many of these seeps are under considerable pressure as there is substantial natural gas mixed in. The seepage rate of each has been mapped and studied for many decades. It has long been observed that the introduction of drilling appears to substantially reduced the seepage rate at many of these underwater sites. Drilling wells significantly reduces natural pressure in these reservoirs, likely leading to the observed reductions in seepage.

Wtf I love Exxon now.
I remember swimming in Santa Barbara growing up (well closer to the Ventura side really) and having to dodge oil on the sand and water.
How did the wildlife adapt to that? There must be some cool species there
I don't know much about it but I have read that the local ecosystem is well-adapted to the oil seep environment.
That area has been like that for something like 100,000 years, which is a considerable amount of time in evolutionary terms.
There is still tons of tar on beaches in Santa Barbara county, mostly all from natural seeps.
Natural seepage is still just as big of an issue now as it was back then in those areas, including Santa Barbara.
To this day if you walk on the beach your soles or the soles of your shoes will get sticky tar spots. You need baby oil wipes to clean them up before entering your home.
And some of it, if not most of it is not natural seepage but early environmental catastrophes in the 50s and 60s, particularly around Summerland.
