These are basic issues of oil supply. If the lady is correct, then a depression is imminent. These issues should be dealt with publicly by more official channels, such as the American Petroleum Institute. Instead, they are confined to obscure Internet discussion forums. That leaves the public without a clear insight into what we are facing.
Public officials prefer to let sleeping dogs lie and lying dogs sleep.
The failure rate, per se, is not extremely high, but the effects of a failure is greater than in many applications. Three were able to redrill and produce, one was not recoverable as to the strata. I have also seen a 12 well field that had only 2 failures. This range appears to be about the norm from others I know in the field. The type of platform makes a difference in how many systems are reachable.
