Thanks for making this explanation video. It surely helps a layman like me to understand more about drilling. Modern drilling is surely an incredible stuff and achievement!

It is interesting that the vertical depths of the wells off of Sakhalin Island only have a true vertical depth of 1km because I have seen them cited as the deepest wells. In particular, I have read that the great depths of these well are evidence in support of the abiotic theory. This would seem to be debunked if the horizontal depth is only 1km. But what about the Tiber field? Did they find oil at 35,000 feet?

Hi Eugene, thanks for your question. Some Sakhalin wells are likely to go deep, we were quoting drilling records, mainly set on one field which may have anomalous well geometries. As for Tiber, in the Gulf of Mexico - it's a little more complicated. First there is over 4,000ft water column before reaching the sea bed. Secondly, the maximum depth was over 35,000ft ("TD"). Oil was recovered from a number of Tertiary-aged sands, however the exact depths of the pay intervals is not a matter of public record, to the best of my knowledge. Hope this clarifies.

Thank you for your detailed response. As I understand it, with regards the oil window there is a limit to the temperature at which petroleum will form from source rock. does this put a theoretical hard-limit on the depth? My motivation for asking is to have the correct information at hand when I encounter proponents of the abiotic oil theory which apparently has some strong adherents in Russia and Ukraine.

@@LewesMintz Hi Eugene, We don't want to get embroiled in the conspiracy theory communities. The earth is flat, Hollywood made up the moon landing etc.There is a well understood progression of maturity which originated in the 'rank' applied to coal maturation. As coals get deeper/hotter they change from lignites to bituminous coals to anthracite to graphite. The latter would be in low-grade metamorphic rocks. There is no single temperature we can quote but there is an effective hard-limit on the depth. The abiotic source argue the complex molecules found in oil are picked up on the way. You can't debate/argue/influence with such people. Try staying out of their way is my advice.
