CO2-Energized-Acid Treatment Reduces Freshwater Use, Boosts Well Performance
Carbon dioxide (CO2) with 30% foam quality (FQ) has been introduced for the first time during acid fracturing treatments in a tight, sour, high-pressure/high-temperature carbonate gas reservoir in Saudi Arabia.
Guest Editorial: Creating Value From Flared Natural Gas
Approximately 5% of world annual gas production is being flared or vented. This is equivalent to approximately 110–140 billion m3 (Bcm) of gas, and equates to the combined gas consumption of Central and South America in 2013.

Are fugitive releases of natural gas and flaring environmental concerns? Can these be ameliorated today and even better in the future? Yes and yes.
Guest Editorial: Climate Policy with Low Oil Prices
Without serious climate policy restrictions, the use of cheaper oil will likely grow and extend its life expectancy throughout the global energy system.
Controlled-Freeze-Zone Technology for the Distillation of High-CO2 Natural Gas
The technology described by the authors provides the simplicity of a single-step distillation process for the separation of CO2 from natural gas. The technology has shown the potential to separate CO2 and other impurities from natural gas more efficiently and more cost-effectively.
