The largest step-rate technological advances That have given us access to huge added amounts of economically-extract able oil I have witnessed in the oil industry in past 4 decades(not in any order):
1.3 dimensional seismic( we can image what we used to have to drill to see)
2. Deep water drilling and production(be cause most of the world is underwater and oil exists there too)
3. Horizontal drilling (now we can explore and develop other than vertically)
4. Stage fraccing(cause the rocks are now so low quality we must create our own permeability)
I dream of what might transpire during the next 40 years

Likely, the difference between now and 40 years from now will be about like the difference between 1890 and 1930 in energy world. Well likely not that stark. But still some pretty big stuff is coming imho in that time frame.
