... and stop the fluid loss by plugging the fractures in formation. These SAPs have shown excellent technical performance; however, they have poor biodegradability, often less than 5% in 28 days (Organization for Economic Co-Operation and Development [OECD 306] Test for Biodegradability in Sea Water...

.... The service company specifications for the development of the low environmental impact fracturing fluid required not only it meet the oil and grease standard but also the toxicity standard for water based drilling mud and a biodegradability standard. The fluid development required it to meet the more...

.... These precipitates include iron hydroxide and iron sulfide. In addition, chelating agents are used as components in many scale removal/prevention formulations. This current study is related to development of improved and biodegradable polyaminocaboxylic acid chelating agent formulations. Chelating formulations...

..., biodegradability, etc.) but little or no attention has been dedicated to the mechanisms of environmental impact The main mechanism of impact of the discharge of drilled cuttings is the organic enrichment of the marine sediment. Organic enrichment is a situation derived from the accumulation of organic matter...
