Abstract

Corrosion can remain a huge obstacle to the rehabilitation project of Missan Oilfields in Iraq, which is detected with high corrosive H2S/CO2 contents. To minimize corrosion risks in the annulus, a packer fluid has been set between the tubing and the casing above the production interval, and to fill the annulus. A series of tests have been carried out, on the basis of annulus conditions, to examine the performance of the designed packer fluid, including the corrosion resistance and the antibacterial capability. The component optimization test showed that under the considered conditions, an organic amine corrosion inhibitor exhibits effective corrosion inhibition than others, as well as the compatibility; in addition, the packer fluid has an excellent antibacterial property, and the growth rates of SRB and TGB can be controlled as low as 0 cells/ml, meeting the operation requirement on-site.
