Predictive and preventive maintenance of oil and gas production pipelines in the area North Monagas-Venezuela
- Corpoven, S.A., Anaco (Venezuela)
Predictive maintenance of oil and gas production pipelines has allowed the prediction of operational failures. Specially due to the thermodynamic behavior of the produced fluids, contaminants present in the oil and gas such as sand, water, H{sub 2}S and CO{sub 2}, asphaltene deposition, high temperatures and pressures, physicochemical characteristics of the soil, etc. lead to risks of the installations. In order to minimize risks of failures, the author has established a control and monitoring preventive program of the variables that influence these conditions, such as: nondestructive 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. Additionally, he has implemented 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 are used. Increasing the protection through preventive and predictive maintenance can reduce the operational risks involved for the oil and gas production.
