A Geologic And Hydrochemical Investigation Of The Suitability Of Central Utah's Navajo Sandstone For The Disposal Of Saline Process Water And Co2, Kevin L. Randall
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Salt water is produced from the Ferron Sandstone Member of the Mancos Shale in central Utah as part of the production of coalbed methane (CBM) and is disposed of by injection predominantly into the Navajo Sandstone between 4,500 feet to 7,300 feet and is considered to be a hazardous waste. Local government agencies are concerned about the potential impacts on shallow groundwater because of this disposal method.
Water samples were gathered from four shallow water-supply wells, and nine salt water disposal (SWD) wells to compare hydrochemistries as an indicator of potential mixing. Shallow water-supply wells are likely recharged by local …
