This work describes the technology for inflow profiling based on the data from intelligent inflow tracers installed on production well completion elements at the Prirazlomnoye oilfield. Specially designed polymer matrices with tracers are installed at certain borehole sections depending on the well trajectory and the distribution of reservoir porosity and permeability. Individual sampling methodology and physical and mathematical model for tracing substance flushout and transportation are selected individually for each borehole and provide for not only qualitative but also quantitative inflow profile in the multizone horizontal well. The innovative technology described in this article helps solving tasks usually addressed by traditional well logging.

This study discusses the experience of Gazprom Neft Shelf LLC in implementing stationary tracing monitoring technology for horizontal wells in the Prirazlomnoye field.
