El futuro de los hidrocarburos.

It is just a matter of time before the demand for oil outstrips supply on account of the concentration of the majority of the world's reserves in politically unstable countries that will no longer be able to meet the vast investment required for production. This will then lead to oil prices possibly in excess of $150/barrel. In terms of natural gas, the reserves are more diversified and have increased considerably as a result of the development of unconventional gas (tight sand). However, the distances between the producing countries and the consumers and the logistical costs in the form of liquefied natural gas (LNG) poses a serious inconvenience that may only be remedied by technological advances.
