... after a number of the well blow-outs and oil spills around the world. The new electromagnetic time domain tool (EM) which is presented uses transient or Pulsed Eddy Current (PEC) measurements to perform quantitative evaluation of downhole corrosion in four concentric tubulars individually...

... Abstract During the lifetime of an oil/gas well, wellbore tubular structure might be subject to combined damage caused by both corrosion and mechanical wear. Therefore, it is necessary to conduct detailed stress analyses including these factors at the stage of tubular design. An integrated...

... and corrosion, and stress variation because of large temperature difference derived from air injectivity difference between layers. Measures to prevent casing damage According above discussion on principles of casing damage for Du66 combustion project, local high temperature is the main cause of casing...

... Abstract With the development of Fire Flooding test, serious corrosion occurred in N80-steel based tubing and casing string and caused severe damages. Wellbore integrity is getting worse, which gives rise to the abandonment of a well section or the whole well. This problem has seriously...

... isolation of the intervals as well as an enhanced methodology for decision making, such as an assessment of the current downhole conditions using ultrasonic logs to evaluate casing corrosion and cement sheath integrity. This allows evaluation of the well before and after abandonment and includes measurement...
