Frack Me!

You can't compare deep sea wells with fracking wells, completely different pressures, materials, and techniques used. Not one issue has been found with fracking, and it is virtually impossible for any gas from 1-6km down to get into an aquifer about 100m down. It's a lot safer enviromentally and for human life than coal mining.

I have been on wells offshore where fracking has been carried out and at depths not dissimilar to onshore. And at pressures rather similar to those required to frac onshore. Its the same technique. Using downhole gauges I used to measure the pressures that were pumped down to fracture the formation.

Where do you feel the significant dissimilarities are? Which materials do you feel are significantly different? The key "ingredient" here is fluid pressure.

The key difference between onshore and offshore is that people who live onshore will be affected directly by any environmental contamination. Offshore, for obvious reasons it can go relatively undetected unless hydrocarbons come to surface in large quantities. However a blowout offshore is a bit more obvious than aquifer contamination onshore making it harder to prove.

We shall see. I foresee fun and games ahead.

Whether onshore or offshore it is entirely possible for fluids from 1 to 6km down to reach the surface and yes, contaminate any aquifer, if there is nothing to seal the pressures in down below.
