Slurry injection into disaggregated earth formations |
摘要 |
Slurries of particulate solids wastes are injected into a disaggregated earth formation through an injection well by predetermining the formation to have a compressive stress in a range of about 300 psi to 2500 psi, a porosity of at least about twenty percent (20%) and disposed between overburden and underburden layers which have a substantially lower permeability than the disposal zone. The disposal zone is disaggregated or "liquified" by injecting substantially solids-free liquid followed by injection of the solids-laden slurry.
