Seismic risk at the LaRonde mine is currently managed through a combination of control measures, including a ground-control-driven mining sequence and level design, dynamic ground support systems, and procedures to limit workforce exposure. These control measures have evolved over time and been...

No significant effect of exposure to NaOH was seen on the relaxation process. 1. INTRODUCTION Completion of oil and gas wells...

... Abstract Chemical treatment is a potential method to decrease shale strength and thereby induce borehole closure and thus the formation of a natural barrier around a hydrocarbon well after completion. A laboratory test was designed in order to investigate whether HCl exposure is a possible way...
