Methods for hydrocarbon recovery from a subsurface formation include removing a mixture comprising hydrocarbons and particulate solids from a first formation. At least a portion of the hydrocarbons are separated from the particulate solids. The particulate solids are separated into a plurality of streams. A mixed slurry comprising a first portion of the plurality of streams is injected through a first pipe into the first formation. A waste stream comprising a second portion of the plurality of streams is injected through a second pipe into a second formation. The first formation and the second formation lie in a substantially vertical line.
