Abstract
Faste avfallsmaterialer i oppslemning injiseres i underjordiske formasjoner i en sone (102) av interesse som har en forholdsvis lav kompresjonsspenning (96) og er omgitt av soner med høyere kompresjonsspenning (98, 100), idet sonen av interesse har vekselvise lag med henholdsvis forholdsvis høy og lav permeabilitet for fluidstrømning. De faste avfallsmaterialer i oppslemning ledes gjennom en injiseringsbrønn (92) gjennom sonen av interesse, for å danne en konvensjonell, to-vinget hydraulisk fraktur (132, 134). Frakturen utvides ved minskning av tendensen til dannelse av filterkake i frakturen nær materiallagene med forholdsvis lav permeabilitet (142, 144), mens det avsettes partikkel- filterkake nær jordlagene med høy permeabilitet (146, 148, 150), for å danne strømningsbaner for klart fluid gjennom frakturen og å muliggjøre at filterkakelagene som avsettes i frakturen bidrar til å tvinge frakturen til a åpne seg.Solid slurry waste materials are injected into underground formations into a zone (102) of interest having a relatively low compression stress (96) and surrounded by zones of higher compression stress (98, 100), the zone of interest having alternate layers of relatively high, respectively. and low permeability for fluid flow. The slurry solid waste materials are passed through an injection well (92) through the zone of interest to form a conventional two-wing hydraulic fracture (132, 134). The fracture is expanded by decreasing the tendency of filter cake formation in the fracture near the relatively low permeability layers (142, 144), while depositing particle filter cake near the high permeability layers (146, 148, 150) to form clear fluid flow paths through the fracture and to enable the filter tile layers deposited in the fracture to force the fracture to open.
