Gas Production Technology

Only 2 years ago, the conventional wisdom was that oily or ­liquids-rich plays were the only place to put capital. Gas assets, especially conventional gas, were for true contrarians. While worldwide oil prices have ­fallen 60% since their 2014 peak, diverse natural gas prices swing between USD 2 and 4/million Btu in the US, USD 8/million Btu in central Europe, and USD 15/million Btu for delivered liquefied natural gas (LNG) in Asia. Depending on your timing and cost structure, gas assets may be a rare highlight in your business in 2015.

Conventional wisdom implies that natural-gas demand will continue to grow, especially in locations where coal is being phased out, nuclear growth has slowed/reversed, and renewables remain a small and intermittent energy source for the foreseeable future.

The underlying fundamentals may tell another story: LNG plants in progress will increase supply by 122 million t/a by 2020, while LNG demand is expected to grow much slower. Even though more LNG import terminals will be completed in the next several years, global regas-facility utilization is only 33% of capacity. Because markets need to balance eventually, will demand grow to soak up the excess supply or will the new volumes be slow to come online?

In free and unregulated markets, the “invisible hand” first described by Adam Smith ultimately guides producers and consumers to a price and quantity that satisfy both parties. Unfortunately, oil and gas markets are far from free and unregulated, so investment time lag, regulations, and politics tend to delay and distort the inevitable balance that must exist in markets. Opinions on the outcome of all these competing factors tend to converge to a group consensus, which is usually just an extrapolation of “more of the same.”  In 1986, we were all convinced there would never be another boom and the then-current bust would last forever. Thirty years, and several boom-and-bust cycles later, we are still making straight-line projections, even though it is clear that the only thing that stays the same … is change.
