Geological Estimates of Methane Availability

  • Ken Deffeyes


The product that we know as natural gas is not pure methane. A few percent of molecules with two and more carbon atoms are usually present. The molecules with 3, 4, and 5 carbon atoms are variously referred to as natural gas liquids, gas condensate, or casinghead gas. Because these molecules with more than one carbon atom are likely to be in demand as petrochemical feedstocks and as liquified natural gas, we can presume that they will normally be removed from natural gas streams and marketed separately at higher prices.
