Predictive maintenance of oil and gas production pipelines has allowed tp predict operational failures. Specially due to the thermodynamic behavior of the produced fluids, contaminants present in the oil and gas such as sand, water, H2S and CO2, asphaltene deposition, high temperatures and pressures, phisicochemical characteristics of the soil, etc. that would lead to risks of the installations.
In order to minimize risks of failures, we have stablish a control and monitoring preventive program of the variables that influence this conditions, such as: non-destructive testing, wall thickness measurements and two dimensional B Scan measurements to detect impurities, laminations and inclusions in the pipeline material, corrosion evaluation of pipelines, characterization of the soil corrosive potential of flow stations and compressing plants.
Aditionally, we have implementede predictive control through the application of external corrosion prevention techniques such as cathodic protection and coatings. For internal corrosion, the use of corrosion inhibitors, asphaltene dispersants and material selection. Increasing the protection through preventive and predictive maintenance we can reduce the operational risks involved for the oil and gas production.
