Upon completion of this course, you will provide a clear definition for the corrosion process, and its impact in all facts, and methods of control of corrosion in oilfields. Also an understanding of corrosion engineering in oil and gas production involving the various methods available for corrosion control, regulatory and safety matters, and the contribution of an integrated monitoring and inspection program for operations and the diagnosis of problems. Finally determine the primary cause of a failure, and take the most effective corrective action.
Who Should Attend ?
Corrosion engineers, and quality control supervisors, oil and gas production engineers, process and water treatment engineers.
Course Outline :
The occurrence of corrosion in oil and gas production.
The nature of the problem down hole corrosion, flowing well, casing corrosion , surface equipment and processing equipment.
Corrosion principles (why metal corrode nature of corrosion reactions, voltage source, and anode/cathode/electrolyte)
The effect of electrolyte composition (conductivity, pH, dissolved gasses, physical variable (temperature/pressure/velocity).
Forms of corrosion (pitting, bimetallic corrosion, erosion corrosion and impingement, intergranular corrosion, hydrogen induced failures, hydrogen blistering, sulfide cracking, high temperature attack)
Forms of corrosion in petroleum production.
Detection of corrosion in oilfield equipment (corrosion specimens/coupons, test nipples)
Electrical and electrochemical methods.
Linear polarization instrument, galvanic probe, hydrogen probe.
Chemical methods for corrosion detection (dissolved iron, corrosion product analysis, gas analysis, and bacterial activity and inhibitor tests).
Selection of corrosion inhibitors/application of corrosion inhibitors.
Survey methods used in cathodic protection. application of cathodic protection to oil and gas production equipment.
