CO2

Saudi Aramco saw a jump in production for a type of EOR that often takes years to see full benefits.

In this study, detailed petrophysical and geological field models focusing on the middle and lower members of the Bakken Formation were developed.

Carbon dioxide (CO2)/water foams are of interest for mobility control in CO2 enhanced oil recovery (EOR) and as energized fracture fluids or as hybrid processes that combine aspects of both processes.

A major oil company is progressing a portfolio of commercial-scale carbon-capture-and-storage (CCS) demonstration projects covering an array of technologies that target applications of relevance to the wider oil and gas industry.

There remain a number of challenges with CO2 EOR. These include gravity override, poor sweep efficiency, and economic factors.

In chemical-looping combustion (CLC), oxygen is transferred from an air reactor to a fuel reactor by means of a solid oxygen carrier.

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.

The deployment of appropriate CO2-separation technologies for natural gas processing is viewed as an abatement measure toward global CO2-emissions reduction. Selection of the optimum technology requires special attentiion.

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.
