.... microbiologically influenced corrosion MIC corrosion model pipeline RBA INTRODUCTION A microbially influenced corrosion (MIC) assessment model has been developed. This MIC assessment model is based on previous MIC corrosion modeling activities ¹ . Particular focus was given to several critical...

...Abstract Corrosion models used in the oil and gas industry are generally aimed at conditions found in pipelines and topside facilities at moderate temperatures and pressures where ideal behavior and solubility for gases can be assumed. The conditions downhole in wells can be very different...

... recognized. Corrosion models have traditionally been used for predictions in industrial applications only when need arises in instances such as a failure analysis, project design, or asset integrity reviews. As process and operating data and lab analytical data become available in real time through...

... hydrogen sulfide corrosion model INTRODUCTION Corrosion predictive models are a very useful tool that can be used to determine corrosion allowances, make predictions of facilities remaining life, and provide guidance in corrosion management. When it comes to internal corrosion of mild steel in the oil...

... a microbiologically influenced corrosion (MIC) risk model has been developed and merged with the internal pitting corrosion model so that the integrated model predicts the optimized pitting corrosion rate due to both non-MIC and MIC activities. In this paper an approach was developed to integrate the internal...

... of corrosive species such as acid gases (CO₂, H₂S) and volatile organic acids. The ability to predict and control TOL corrosion is necessary to ensure long term integrity of these pipelines. This paper will discuss a TOL corrosion model that can be used to assess the risk of TOL corrosion...

.... The electrochemical corrosion model was developed by modeling polarization curves based on the given species concentrations. The required electrochemical parameters (e.g., exchange current densities, Tafel slopes and reaction orders) for different reactions were determined from experiments conducted in glass cells...

... TO MODELS INPUTS In the 2^nd step all the required data by the applied models have been identified. In this stage precision of the input data is one of the success key points. As Sergio D. Kapusta et al. stated, most of the corrosion models use several parameters related to environment...

... years. Strictly speaking, the existing mechanistic CO₂ corrosion models can only be used in single-phase flow. To add the capability of predicting corrosion in multiphase flow, the mass transfer and the turbulent diffusivity correlations in the models have to be modified to properly calculate...
