Oil base economies and future changes ahead on our living conditions

I always wake up each morning thinking if our oil base economy is sutainable in time. While studying Petroleum Engineering we learned of the natural declination of the oil & gas fields an type of natural energy that allow us to recover this non renewable resource. Today the biggest economies consume large amounts of oil & gas and this are the base of their economic growth.
Today most of the Middle East fields are in declination and the production is held by drilling more infield wells, horizontal wells and improving secondary recovery methods.
Technology is key to reach reservoirs as they get deeper and more complex to produce, there is a limit to all this efforts, and we will be facing a sudden drop on production in the near future as resources turn more scarce.
Most of the cities in North America are designed for automobile transportation and the distances are big between homes and shopping areas, an average conmuter makes 60 miles a day. That explains the huge amounts of gas consumed. If we face a sudden change and fuel is not available, some of our big cities will literally collapse. 
The quest to secure energy resources has been understood by the big economies and companies are in the quest to secure prospects worldwide. The recent Exxon Mobil farm in deal in Argentina shows the interest in developing complex reservoirs of shale gas in the Neuquen basin. Sinopec of china are also moving in the Canada Oil Sands and BP on the Artic exploration in Russia.  We can see by this deals that the complexity in reaching this reservoirs is increasing and new technologies are being develop as we speak to produce them effectively and economically.

See ya Soon!
