Control of Corrosion of Electrical Submersible Wells and Rod Pumped Wells in Varied Carbon Dioxide Environments Using Batch Treatment

Product Number: 51317--9450-SG

ISBN: 9450 2017 CP

Author: Sunder Ramachandran

Publication Date: 2017

$20.00

This paper describes the performance of film persistent corrosion inhibitors that are effective at fairly high temperatures and in systems that see large amounts of carbon dioxide (CO2). Use of batch treatment with the correct chemical, at the proper frequency resulted in substantial decrease in operating cost.

Application of corrosion inhibitors confer many advantages for combatting internal pipeline corrosion in the upstream oil and gas industry. It is known that the associated costs for using corrosion inhibitors are low compared to other mitigation techniques [1]. For continuous injection procedures, water-soluble inhibitors are not expected to form long-lasting films, so they must be continuously injected to maintain their effectiveness. Batch inhibitors are usually higher molecular weight species and oil soluble. They tend to be more tenacious, providing a protective barrier between the water and the metal over a long period of time.

A fit for purpose qualification of new corrosion inhibitors was carried out for in a gas and condensate field. The depth of production well is 4,500 m and the bottom hole temperature and pressure are 180ºC and 50 MPa respectively. The methodology and result of the inhibitor evaluation under a sweet condition was summarized. Two brands of corrosion inhibitors had been used each for production tubing and flowline in the field. New corrosion inhibitors were evaluated for the both applications. The corrosion inhibitor efficiency for high shear service and the adhesion tendency were evaluated with a rotating cage autoclave and a dip and drip experiment respectively. In order to evaluate the tendency of emulsion forming, oil, brine and an inhibitor were poured into a centrifuge tube and it was shaken intensely. Gas chromatograph - mass spectrometer (GC-MS) and Fourier transform infrared spectroscopy (FT-IR) were studied to measure the residual amount of inhibitor. Finally, the field trial was conducted with a new inhibitor. The new inhibitor was adopted successfully for the both services. The risk of emulsion forming became lower because the mixing of two brands of inhibitors was avoided. Reducing the number of the chemicals contributed to reduction of the operation cost too.
