TL;DR: This study examines three large-scale sites where CO2 is injected at rates of ∼1 megatonne/y or more: Sleipner, Weyburn, and In Salah, with particular focus on the risks to storage security posed by geomechanical deformation.

TL;DR: In this paper, the authors developed the concept of using observations of micro-seismic activity to help ground truth geomechanical models and found that an alternative model whose reservoir is an order of magnitude softer than lab core-sample measurements provides a much better match with observation, as it leads shear stresses to increase above the production wells, promoting microseismicity in these areas and generates changes in effective horizontal stresses that match well with Swave splitting observations.

TL;DR: In this article, the authors present the first detailed UK experimental survey of public perceptions of shale gas fracking, including analysis of the effects of different messages and the relative influence of different audience, message and contextual factors on support and risk perceptions in respect of the UK fracking.

TL;DR: In this article, a workflow strategy for automatic and effective processing of passive microseismic data sets, which are ever increasing in size, is presented, which is based on characteristic differences between the two independent eigenvalue and cross-correlation splitting techniques.
