TENORM Oil and Gas Production Wastes Radiation
Feb 23 2021 · API has determined that most sludge settles out of the production stream and remains in the oil stock and water storage tanks. Like contaminated scale sludge contains more Ra-226 than Ra-228. The average concentration of radium in sludges is estimated to be 2.775 Bq/g (75 pCi/g). This may vary considerably from site to site.

Surfactant Enhanced Biodegradation of Petroleum
May 24 2010 · Bioremediation has been recognized as an effective method to treat petroleum hydrocarbon pollutants. However the biodegradation of crude oil-contaminated sludge could be a time-consuming and low-efficiency process. Among the reasons is that some petroleum hydrocarbons in the sludge are unavailable for micro-organisms utilization.
