Paper presented at the Gulf Rocks 2004, the 6th North America Rock Mechanics Symposium (NARMS), June 5–9, 2004
Paper Number: ARMA-04-634
... permeability reduction associated with rock compaction around the wellbore region is a well-known phenomenon in oil and gas production in weak reservoirs. As a consequence, rock compaction has adverse effects on well productivity. To quantify well productivity reduction caused by rock compaction, a coupled...

Paper Number: ARMA-2000-0481
... ABSTRACT ABSTRACT: In contrast to typical excavations in civil engineering construction, mine openings often create locally reduced confinement and relaxation or tension in the backs or walls. Boundary-parallel stress reduction, or relaxation, can have devastating consequences in structurally...

... reduction rockburst ABSTRACT: This paper describes a numerical modelling technique that can be used to model destress blasting in sequential mining operations at depth. Stresses and mining induced strain energy densities are computed at the end of each mining step. Destress blasting, a technique...

... curve permeability increases markedly. The decrease in permeability is believed to be due to a reduction of pore space. The constant permeability is believed to be due to a subsequent tight packing of grains where the pore space cannot become smaller, yet the stress is not sufficient to initiate cracks...
