For reliability and safety issues of injection wells, corrosion resistance materials used needs to be determined. Herein, representative low-cost materials, including carbon steel X70/1.8977 low alloyed 1.7225, were embedded in mortar mimic the realistic casing-mortar interface. Two types cement investigated: (1) Dyckerhoff Variodur commercial Portland cement, representing a highly acidic resis...

Imidazoline obtained from the essential oil contained in Pouteria sapota seed was tested as an environmentally-friendly corrosion inhibitor of 1018 carbon steel CO2 saturated 3.5 % NaCl solution using electrochemical techniques. This imidazoline contains fatty acids with presence long hydrophobic chains, 52.73 unsaturated (oleic and linolenic acids) 40 (palmitic myristic compounds. Polarization...

Carbon dioxide is known as a hazardous material with acidic property that can be found as impurity in natural gas reservoirs with a broad range of 2 up to 40 %. Therefore, many efforts have been directed to remove and separate carbon dioxide from methane to prevent corrosion problems as well as improving the natural gas energy content. In this study, two molecular sieves, silicoaluminophosphate...

Preexisting wells and well bores are high-permeability pathways through the crust, and as such present zones of elevated risk to CO2 storage projects. Although current well closure and abandonment technology appears sufficient to contain CO2 at most sites, individual wells may suffer from a variety of factors that limit their integrity, including improper cementation, improper plugging, overpre...

Chloride ingress and carbonation cause corrosion of reinforced concrete (RC) structures affecting its operational life. Experimental evidence indicates that these deterioration processes are highly influenced by CO2 emissions and climatic conditions in the surrounding environment –i.e. temperature, humidity, etc. Since studies on global warming announce changes in climate, the impact of changin...
