Estudio del uso de tubería especial de producción para mitigar la corrosión en el Campo Palo Azul, Reservorio Hollín

Abstract

The present work is born from the need to control the high corrosion rate in Palo Azul field wells, a comparative analysis is made for the selection of special tubings for environments where sweet corrosion or corrosion is present due to the presence of CO2. This analysis will be carried out in a technical and economical way, using methods of corrosion analysis and financial indicators. In this way, the best option is identified to reduce continuous shutdowns due to the presence of corrosion: production losses, constant pipe changes and high costs for workovers (W.O). For the development, updated data of the Palo Azul field from the wells: PLAB-03, PLAC-013, PLAD-015 and PLAN-051H, have been used, these wells are being produced from the Hollín formation and were chosen because of the high Corrosion they present. At the moment of studying the types of tubings that allow to mitigate the corrosive process have been denominated: Carbon steel, API 1% Cr, API 3% Cr and API 13% Cr, this allowed to accelerate the study process as the tubings with Cr to analyze them according to the percentage of chromium.
