Deep Underground Science and Engineering, EarlyView.This study presents an integrated workflow to evaluate secure and large‐scale CO2 storage in depleted oil reservoirs of the Cambay Basin, India. Industrial CO2 sources are systematically matched with mature oil fields using a quantitative source–sink framework to minimize transport distance and cost.

Image source detection for geoacoustic inversion by Teager-Kaiser energy operator [PDF]
, 2014 This letter presents an improvement of the image source method (ISM) for geoacoustic inversion. The new algorithm is based on the Teager-Kaiser Energy Operator which ampli es the discontinuities in signals while the soft transitions are reduced.

Deep Underground Science and Engineering, EarlyView.This study quantitatively analyzed the spatiotemporal evolution of stress redistribution ahead of the working face by integrating coal seam distribution, tectonic stress anomalies, gas pressure, and mining‐induced disturbances. An R‐value criterion for coal and gas outburst (CGO) risk assessment was established based on energy principles.

A note on the Smarandache inversion sequence [PDF]
, 2007 In a recent paper, Muneer introduced the Smarandache inversion sequence. In this paper, we study some properties of the Smarandache inversion sequence. Moreover, we find the necessary and su±cient condition such that [SI(n)]2 + [SI(n + 1)]2 is a perfect
