Abstract EN
The flow of crude oil, water, and gas from the reservoirs through the wellheads results in its deterioration.
This deterioration which is due to the impact of turbulence, corrosion, and erosion significantly reduces the integrity of the wellheads.
Effectively managing the wellheads, therefore, requires the knowledge of the extent to which these factors contribute to its degradation.
In this paper, the contribution of some operating parameters (temperature, CO2 partial pressure, flow rate, and pH) on the corrosion rate of oil and gas wellheads was studied.
Field data from onshore oil and gas fields were analysed with multiple linear regression model to determine the dependency of the corrosion rate on the operating parameters.
ANOVA, P value test, and multiple regression coefficients were used in the statistical analysis of the results, while in previous experimental results, de Waard-Milliams models and de Waard-Lotz model were used to validate the modelled wellhead corrosion rates.
The study shows that the operating parameters contribute to about 26% of the wellhead corrosion rate.
The predicted corrosion models also showed a good agreement with the field data and the de Waard-Lotz models but mixed results with the experimental results and the de Waard-Milliams models.
