Informaton Circular 8769: Well Construction Information for In Situ Uranium Leaching

Details

• Personal Author:
  Connor, Kevin ; Tweeton, Daryl R.
• Description:
  This Bureau of Mines publication describes present practices of making injection wells for in situ uranium leaching. Casings, screens, drilling fluids, coring, logging, cementing, and developing are discussed with the objective of aiding those who are starting an in situ leaching operation. Improper choices of materials or techniques can result in wells that are either useless or wells that have an undesirably high resistance to injection. Important factors include careful selection of screen slot size, use of logs for choosing the cementing basket depth, proper cementing techniques, and careful choice, use, and flushing of drilling fluids. The information was obtained through observation of well construction and through discussion with in situ leaching companies, drillers, and suppliers. [Description provided by NIOSH]
