Quantum Origin of the Greenhouse Effect

For an overview of some new work on why the CO2 molecule is so good at trapping heat see https://t.co/px4uKPZliw

Those interested in more detail can find the original paper at https://t.co/ZC3UqApfby

A recent paper at https://t.co/TjS1rDgZVS discusses the acoustic properties of high porosity sandstones required for monitoring injection and movement of CO2 in such formations using elastic waves.

@WeAreSeismica What about rock physics? Rock physics provides the link between seismic properties and the intrinsic properties of rocks, such as mineralogy, porosity, stress, rock fabric and fractures.

@LDR_Strasbourg @WadsworthFabian A layering?

[Colin Sayers @colin_sayers]

@LDR_Strasbourg @WadsworthFabian A loading, a compaction or a deformation of sandstones?

[Colin Sayers @colin_sayers]

@LDR_Strasbourg @WadsworthFabian A deposition or a sprinkling of sandstones?

[Colin Sayers @colin_sayers]

@LDR_Strasbourg @WadsworthFabian A ripple of sandstones?

[Colin Sayers @colin_sayers]

@LDR_Strasbourg @WadsworthFabian A compaction or a band of sandstones?

[Colin Sayers @colin_sayers]

@LDR_Strasbourg @WadsworthFabian A flow or a percolation of sandstones?

@kwinkunks @flohorovicic How many decimal places are there?

[Colin Sayers @colin_sayers]

@kwinkunks @flohorovicic Rounding error?

@stress_driven Rock Physics provides relations between observables, such as seismic properties and permeability, and rock composition, pore fluid, pore pressure, stress, etc. Understanding such relations can contribute to prediction of fluid flow, stress changes, etc. for planning purposes.
