| Leakage Rates The Palos Verde fault in Santa Monica Bay, California seeps oil at the rate of 10-15 bbl/day. How fast is that? That's in only one million years! The Coal Point seep, over a fault swarm in the Santa Barbara Channel, California, is leaking at 50-70 bbl/day or more than in a million years. Some faults seal. Some faults leak. Can you tell the difference? We can. Really. | This is a sample Seep rates are from Wilkinson, E.R., 1971, California offshore oil and gas seeps: California Oil Fields-Summary Operations, vol. 57(1), p. 5-28 | |
