Abstract:Summary
The injection of sand-entrained radioisotopes at the latest time before fracturing fluid enters the wellbore minimizes personnel exposure to radiation, contamination of surface equipment, and hazards of transporting radioactive material. This paper presents design and operational details of the devices used for wellhead injection of radioisotopes, transportation considerations, disposal of leftover radioactive sand, closed-loop control of injection, and a comparison of the injection p… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
