Abstract: Liquid wastes and slurries of ground solid wastes are injected into earth formation zones (12) which have a fluid content of fluid similar to the liquid wastes or slurry which is below the irreducible saturation level for the liquid wastes or slurry to be injected. The formation (12) may be non-hydrocarbon bearing or a depleted hydrocarbon bearing reservoir which has been depleted by enhanced fluid recovery techniques below its ambient irreducible fluid saturation value.

Abstract: Floating roof storage tanks (10) are modified to include a foam surge tank (28), a low-pressure blower (44) and a foam generator (48) for generating vapor-suppressing foam during withdrawal of liquid from the storage tank and after the floating roof (16) reaches its lowest elevation in the storage tank so that the tank space previously occupied by volatile liquid is provided with a vapor-suppressing foam blanket during liquid withdrawal and refill. The surge tank is mounted directly on the floating roof and discharges its foam through an opening in the roof into the tank storage space. During liquid refill the foam may be forced out through a vent conduit (58) onto the roof of the tank and dissolved and recovered.

Abstract: Predetermined quantities of slurried solids wastes are injected into earth formation waste disposal zones (23) having a predetermined in situ stress distribution and compaction rate for a predetermined hydraulic injection pressure and wherein the disposal zones (23) are bounded by zones (24, 26) having greater in situ stresses. Unconsolidated or lightly cemented formation zones may be used for waste disposal wherein it is determined that a substantial compaction of the material defining opposed faces of hydraulic fractures (22) may occur. Fracture volume available for retention of solids in the slurry is calculated based on fracture height, fracture length, elastic deflection of the fracture faces, compaction of the fracture faces and the number of fractures based on either unequal or substantially equal horizontal stress distributions.

Abstract: Deposits are removed from cargo tanks and the like by a sequential operation in which a portion of each tank is filled with a solvent and the solvent is gradually moved upwards by a ballast of water so as to contact the tank surface and dissolve the deposits, followed by moving the water to the next tank causing the solvent to move back down and contact the tank surfaces a second time to effect further removal of the residual deposit. As illustrated in the figure, tanker (10) has cargo tanks A through O. Tanks A-D initially hold a portion of solvent at the bottom. Ballast water is pumped into A so as to cause solvent to move upwards and contact the tank surface and dissolve the residues deposited thereon. Water is then pumped from A to B causing solvent in A to move down. This operation is repeated for tanks B and C. Solvent is sequentially moved from A to E, B to F and C to G, and so on. Tanks E-F are cleaned in the same manner as tanks A-C. This sequential transfer of solvent and water is continued until all the tank surfaces are contacted with the solvent.

Abstract: Slurries of relatively fine particles of solids wastes and similar materials are disposed of through injection wells (24) which penetrate earth formation (13) disposal zones which have a minimum in situ compressive stress generally less than an overburden zone (14) and an underburden zone (18) adjacent to the disposal zone (16). The disposal zone preferably has a permeability greater than the overburden and underburden zones. The slurry is injected through a disposal well intersecting all of the zones and having perforations (44, 46, 48) preferably communicating the slurry with the underburden zone to provide for lateral growth of the hydraulically fractured disposal zone as the solids filter cake plates out on the fracture faces of the disposal zone without substantially penetrating the overburden zone.

Abstract: Slurried solid waste materials are injected into subterranean earth formations in a zone of interest (102) which has a relatively low in situ compressive stress (96) bounded by zones of higher in situ compressive stress (98, 100) and wherein the zone of interest has alternate layers of material of relatively high and low permeability to fluid flow, respectively. The solid waste slurry is conducted through an injection well (92) penetrating the zone of interest to form a conventional two-winged hydraulic fracture (132, 134). The fracture is extended by reducing the tendency to form filtercake in the fracture adjacent to the layers of material of relatively low permeability (142, 144) while depositing particle filtercake adjacent the earth layers of high permeability (146, 148, 150) so as to provide clear fluid flowpaths through the fracture while allowing the filtercake layers disposed in the fracture to assist in propping the fracture open.
