The paper under consideration presents the field experience of using the tracer’s inflow profile monitoring system in the cemented completion for the reduction of environmental risks. Nowadays there are no examples of the use of tracer’s inflow profile monitoring systems for cemented completion in world practice. Existing technologies are unable to perform high-quality measurements in these conditions, or there is no such opportunity as a result of the technological limitations. Oil producing companies are forced to bear significant financial costs and increased operational risks when operating the horizontal wells using conventional methods of production logging with the delivery of complex measuring equipment to the target depth on a geophysical cable or with the use of coil tubing. Oil and gas production companies have to reduce the production logging programs in order to reduce the costs, which excludes the possibility of reaching the maximum potential of the hydrocarbon recovery in the long term. The tracer’s inflow profile monitoring technologies used in the jobs described in this article enable the high-quality monitoring of the well’s operation for a long time without interrupting the production process, at the same time significantly reducing capital and operating costs along with reducing environmental risks during well operation.
