Conservation of Fresh-Water Resources by Deep-well Disposal of Liquid Wastes

摘要

Geological and engineering parameters which govern the disposal of liquid-waste material by deep-well injection were evaluated in Alabama. A study was made of geology to identify potentially favorable subsurface reservoirs. Physical properties controlling fluid movement and storage, and liquid wastes from industries were injected into core samples of actual reservoir rocks. Parameters required for confinement of wastes to assure the isolation of fresh water and other natural resources from adverse effects of waste injection were studied. A design and cost procedure was supplemented by a computer program to provide rapid feasibility studies. Data provided by wells drilled for oil and gas show several potential receptive horizons in the southwest portion of the state near Mobile. Until definition of legal responsibilities is clarified, disposal of liquid wastes in deep-wells should be undertaken only after study of capacity, permeability, confining beds, and control of the flow stream. A bibliography is included containing 460 entries. (WRSIC abstract)
