Shale gas and non-aqueous fracturing fluids: Opportunities and challenges for supercritical CO2
Richard S. Middleton,J. William Carey,Robert P. Currier,Jeffrey D. Hyman,Qinjun Kang,Satish Karra,Joaquin Jimenez-Martinez,Mark L. Porter,Hari S. Viswanathan +8 more
TL;DR: In this paper, the benefits and drawbacks of using CO2 as a working fluid for shale gas production were analyzed using a combination of new experimental and modeling data at multiple scales, and the potential advantages of CO2 including enhanced fracturing and fracture propagation, reduction of flow blocking mechanisms, increased desorption of methane adsorbed in organic-rich parts of the shale, and a reduction or elimination of the deep re-injection of flow-back water that has been linked to induced seismicity and other environmental concerns.

A new dynamic approach for statistical optimization of GNSS radio occultation bending angles for optimal climate monitoring utility
Yongxiang Li,Gottfried Kirchengast,Barbara Scherllin-Pirscher,Suqin Wu,M. Schwaerz,J. Fritzer,S. Zhang,Brett Carter,Kefei Zhang +8 more
TL;DR: An advanced dynamic statistical optimization algorithm is introduced, which uses bending angles from multiple days of European Centre for Medium-range Weather Forecasts (ECMWF) short-range forecast and analysis fields, together with averaged-observed bending angles, to obtain background profiles and associated error covariance matrices with geographically varying background uncertainty estimates on a daily updated basis.

Earthquake triggering and large-scale geologic storage of carbon dioxide
TL;DR: It is argued here that there is a high probability that earthquakes will be triggered by injection of large volumes of CO2 into the brittle rocks commonly found in continental interiors, and large-scale CCS is a risky, and likely unsuccessful, strategy for significantly reducing greenhouse gas emissions.
