Abstract

Scaling in the production tube can directly disrupt production, resulting in decreased production rates, pressure, and extra work on the workover, resulting in additional costs. The scale prevention method for tubing production uses an inhibitor, but many factors cause the inhibitor not to work optimally. Some scale deposes only in a particular area in the production tube due to turbulence flow, temperature, and pressure differences. The direct assessment using the Coiled Tubing Unit (CTU) will assess the calcite scale formation location based on well intervention result. The use of coiled tubing is combined with the acid injection; thus, the amount of calcite reacts with the acid in the 'tagged area' is measured to describe the amount of deposed calcite. In AH wells that have 88% water cut and with a scale index of 4.1, the estimated amount of carbonate is 15.10 kg.
