Naturally Occurring Radioactive Materials (NORM) is a common and costly contaminant of produced waters associated with natural gas production and exploration. One way of combating this problem is by identifying the problem beforehand. Our approach to this problem involves development of NORM prediction capabilities based on the geological environment. During quarter fifteen of this project, work has continued under the recently approved revisions. We have selected sampling sites and are awaiting samples for analysis. In addition, the QA/QC plans are in the final stages in anticipation of sample acquisition.
