A toting apparatus can include a bucket, a combination lid and seat cushion, and a harness for carrying the apparatus while the lid covers the top opening of the bucket and the cushion is in the inflated or deflated configuration. The cushion can be formed by a drop-stitch type bladder inflatable using a common hand-operated bicycle pump. The harness can include a belt that wraps around the bucket and a pair or diametrically spaced-apart straps that adjustably and snuggly attach to a central handle structure atop the lid. Various corresponding patches of hook-and-vane style fabric fasteners allow for releasable affixation of various components of the apparatus. Thus the harness can be made of durable flexible fabric.

Weakly consolidated hydrocarbon fluid bearing earth formation zones having a cohesive strength of about 500 psi or less are produced by completing a well penetrating the zone and initiating production of solids laden fluid from the zone through the well to generate a near wellbore cavity. Production of solids laden fluid is continued until the cavity grows to a point wherein the fluid velocity across the cavity face decreases to a value below the solids particulate transport velocity wherein continued production of fluid will result in a very low or negligible rate of production of solids particulates. Solids particulates are separated from the produced mixture at the surface, the solids are treated to reduce the particle size and reinjected in a slurry into a disposal well for disposal in a hydraulically fractured or disaggregated formation zone remote from the production zone. Cavity growth and production may be carried out by throttling a free flowing well or by artificial lift, preferably utilizing power fluid and a hydraulic jet pump or gas lift techniques.

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.
