Abstract

Permits for disposing of salty oil-production water have been issued for 19 wells in the Greater Altamont-Bluebell field, Utah. During 1986 more than 500 million gal of production water were injected into the Duchesne River, the Uinta, and the Green River Formations through 18 of these wells. The physical and chemical effects of injecting this water on aquifers containing potable water are poorly understood. Interfingering and the structural configuration of these formations add complexity to the description of the geometry and hydrogeology of the groundwater system. A preliminary assessment of the problem indicates that numerical modeling may offer a method of estimating the hydrologic and hydrochemical effects of injection. Modeling possibilities include variable-density, three-dimensional flow, sectional transport, and areal transport modeling. Data needed to develop these models can be derived from a synthesis of geologic, hydrologic, and hydrochemical data already available in the files of State and Federal agencies, oil companies, and private data-base companies. Results from each modeling phase would contribute information for implementing the following phase. The result would be a better understanding of how water moves naturally through the groundwater system, the extent of alterations of both vertical and horizontal flow near the disposal wells, and an overall concept of the effects of deep injection on near-surface aquifers.
