Application of the knowledge of internal corrosion processes and their control in upstream oil and gas production requires that this knowledge is consolidated in the form of practical tools that can be used by engineers for design and operation purposes. An example of a prediction tool will be discussed that contains corrosion rate models for the main corrosion mechanisms. With this engineering spreadsheet, the operational conditions can be identified under which a corrosive, wet hydrocarbon production stream can be transported in a pipeline or downhole tubing of carbon steel. Examples of uses are given. Corrosion rate models for the corrodents CO2, H2S, (organic) acids, bacteria, and oxygen are described. The corrosion rate models are integrated with models for water chemistry, multi-phase flow, oil protectiveness, heat transfer, and thermodynamics. Elevation effects can be simulated. Entries for the main corrosion control options allow considering various scenarios for corrosion mitigation.
