Corrosion monitoring and inhibition in Khuff gas wells. [Bahrain]
Khuff gas has been produced in Bahrain for thirteen years. The gas is potentially corrosive and since 1970, shortly after initial production, the wells have been batch treated with corrosion inhibitor. Caliper surveys and iron counts have been the main techniques used for corrosion rate monitoring. In general, corrosion rates are found to be low, however accelerated corrosion was detected in two wells for a short time. Subsequent monitoring has failed to detect continued corrosion. An experiment utilizing a gradiomanometer logging tool to track the inhibitor and tests for residual inhibitor in the produced fluids show that batch treating effectively contacts the tubing string to bottom and protects the tubing for approximately 6 months.
