{Question 1 & 2} When this shift happens, the US relationship with Saudi Arabia, a relatively minor producer of natural gas, would diminish. It would perhaps be replaced (i) by new ties (ii) Iran and Qatar, (iii) the second and third leading producers (iv) of gas.

{Question 3 & 4} Before this happens, a worldwide infrastructure for natural gas, such as that now enjoyed by oil, must emerge (i). Natural gas is abundant, but it is (ii) in out-of-the-way places, and the system (iii) for transporting it is comparatively underdeveloped. Unlike oil, natural gas cannot be readily stored and must, therefore, be transported immediately, either by pipeline or by seagoing vessel.
