TL;DR: There are a large number of methods for quantifying porosity, and an increasingly complex idea of what it means to do so as discussed by the authors, which is why it is important to quantify the relationships between porosity and storage, transport and rock properties, however, the pore structure must be measured and quantitatively described.

TL;DR: Carbon dioxide capture and sequestration (CCS) in deep geological formations has recently emerged as an important option for reducing greenhouse emissions as discussed by the authors, and if CCS is implemented on the scale needed to make noticeable reductions in atmospheric CO2, a billion metric tons or more must be sequestered annually, a 250 fold increase over the amount sequestered today.

TL;DR: In this article, 1600 t of CO2 were injected at 1500 m depth into a 24m-thick sandstone section of the Frio Formation, a regional brine and oil reservoir in the U.S Gulf Coast.

TL;DR: A detailed review of the major methods for determining fractionation factors can be found in this article, along with a discussion of the advantages and disadvantages of each of these methods in the context of stable isotope geochemistry.

TL;DR: Current recommendations for evaluation of adrenal incidentaloma are likely to result in significant costs, both financial and emotional, due to high false-positive rates, which argues for a review of current guidelines.
