Corrosion Prediction and Materials Selection for Oil and Gas Producing Environments

Abstract

Abstract A computer model is described which predicts corrosion rates of carbon steel flowlines and tubing in the presence of carbon dioxide. The model can be applied also for processing facility piping and equipment. The influences of dissolved corrosion products, hydrogen sulfide, crude oil type, acetic acid and flow regime on the corrosion rate are predicted. Inhibition scenarios can be compared and, for highly corrosive environments, the model incorporates the evaluation of a number of Corrosion Resistant Alloys and incorporates a life-cycle cost evaluation.
