This paper presents attempts to reduce the concentration of organic pollutants in oilfield produced wastewater before its discharge into natural water bodies or reinjection wells. The contaminant content was significantly decreased by treatment, based on solid phase adsorption, photocatalytic degradation molecules and chemical oxidation oily compounds. study conducted with real wastewater, whic...

Wellbore instability is the primary technical problem that restricts low-cost drilling of long-interval horizontal wells in shale formation Jidong Oilfield. Based on evaluation mineral composition, structure and physicochemical properties shale, this paper investigates mechanical behavior characteristics under fluid action by combining theoretical analysis, experimental numerical simulation. Du...
