Annotation:

Marker studies of the hydrocarbons inflow profile in horizontal wells with a multi-stage hydraulic fracturing (MSHF), which are currently actively used to study both a single well and a field development control, make a significant contribution to improving the economic efficiency of oil and gas producing enterprises. At the same time, development of marker research technology has a potential for development in the field of increasing the accuracy of determining the flow rate separately of each stage of hydraulic fracturing. The article presents the results of a theoretical calculation that simulates the long-term operation of a horizontal well with a staged hydraulic fracturing, showing the potential for distortion of the production rate by stages due to uneven washing out of the polymer layer with markers by the produced fluid. A way is proposed for the development of marker research technology in the field of increasing the accuracy of determining the flow rate separately for each stage in the light of a long period of operation.
