... Abstract We injected carbon dioxide (CO 2 ) into a hole drilled around 8 m long in a granitic hot rock from the floor of the tunnel. We drilled four AE (acoustic emission) monitoring holes parallel 1 m far away from the injection hole and monitored AE events induced with hydraulic fracturing...

... ABSTRACT: Fluid injection into the subsurface may trigger seismic events when shear stress acting on a fracture/fault plane exceeds its shear strength. During injection tests at the CO 2 storage pilot at Longyearbyen (LYB), Svalbard, seismic- and non-seismic slipevents were experienced. Two...

... ABSTRACT: A coupled flow-geomechanical modelling study has been carried out in an effort to match the flowing bottomhole pressures and InSAR surface uplift time series at the three injection wells over the seven years CO 2 injection period at In Salah. The surface deformation data covers...

... ABSTRACT: Carbon dioxide (CO 2 ) storage in deep coal seams significantly alters the petro-physical properties of those coal masses, hence precisely evaluation of such alternations is difficult due to the highly heterogeneous nature of coal. This urges the important of testing reconstituted...

... Abstract Global warming is one of the major threats of 21st century and the CO 2 sequestration in unmineable coal seams can be a feasible solution to this problem. However, the effect of CO 2 on the physical and mechanical properties of the host rock has a major control on the storage...

... at In Salah, Algeria. Int. J. Greenhouse Gas Control, 4, 225 230. 1310 Abstract The injection of CO 2 into a reservoir can influence the initial stress state significantly due to changes in pore pressures. As a result, the integrity of the cap rock can be affected and existing faults may be reactivated...

... Abstract Wellbore integrity is a key performance criterion in the safe long-term storage of CO 2 in underground geological reservoirs. In this study, resistance to acidic attack of two cements is assessed by dynamic laboratory experiments under real reservoir conditions (50°C; 150 bar...

... application examples are discussed in some detail: shale gas extraction, CO 2 storage, and radioactive waste disposal—with the emphasis being on successfully achieving the project objectives. The paper concludes with ten recommendations, concentrating on the further development of the subjects of uncertainty...

... Abstract Geologic sequestration of anthropogenic greenhouse gases into deep geological reservoirs like coal seams has caught attention worldwide. The potential of coal to adsorb CO 2 and preferentially release methane partly offsets the cost of capture, transport and storage of the gases...
