Hello my dear friend @wilmer14molina.
The rotary drilling technique is the safest when taking care not to generate a blowout, because with rotary drilling you can pump a drilling fluid while drilling and thereby generate a hydrostatic pressure to withstand the formation pressure.
On the other hand, percussion drilling was a technique where there was no pressure control and a blowout could occur and spill hydrocarbons without control.
Currently drilling is done with the rotary drilling technique which does not have an impact on environmental pollution, since the burning of fossil fuels is something else, and it is where the environment is polluted with greenhouse gases.
To be opposed to the drilling of oil wells is to be opposed to the drilling of water wells, since the same principle is used, it makes no sense to be opposed to this technique.
If it is not about being opposed to the drilling of wells, but to the production of hydrocarbons, then it is a hypocrisy, because oil is not only used to extract gasoline, the plastic that we all use is extracted from it, asphalt is extracted to asphalt the roads of the world, lubricants are extracted from it that even the asphalt is used to asphalt the roads of the world, It is not a question of whether we agree or not, it is a question of if we do not like the production of oil, then we must find a substitute for all oil derivatives.
So far I do not know of a substitute for all oil and natural gas derivatives that would make it possible to stop producing oil, it is very easy to say I do not agree with this and that practice, but we do not know everything that is behind it.

The oil spill resulting from a blowout has not been due to the practice of drilling a well, but by negligence of the personnel working, because when drilling offshore should apply the same principles of well control that is used in drilling on land, for example in the spill that occurred in the Gulf of Mexico in the deep horizon platform could have been avoided, as long as you could have taken reading of the signals that was giving the well of the onslaught of unwanted fluids of the formation into the well. By the time they wanted to react it was too late.
Thank you very much for your comment dear friend, I hope to have clarified your doubts.
