The resource potential of the Bazhenov formation is very highly estimated and chiefly involves kerogen reserves. However, currently the application of cutting-edge technologies providing efficient and economically viable industrial development is required. The present article discloses the results of applying various horizontal well production logging technologies with multistage hydraulic fracturing in the Bazhenov formation deposits at one of the fields that has been developed since 2015.

There has been an increased interest in horizontal wells production logging using markers due to objective difficulties not only in conducting geophysical production logging and data interpretation, but also because existing technologies provide bottom hole data only for a very short time period when the PLT complex is in the well. Marker technologies enable users to obtain data in a much larger volume and practically non-stop for several years without changing the well mode of operation. This in turn allows for analyzing the influence of many external factors on the horizontal well intervals operation. This article presents the experience of marker technologies that were tested and implemented at Gazpromneft PJSC sites from 2016 to 2019, and is aimed at the systematization of objectives and requirements for the technology, as well as addressing important issues during the tendering procedures for the oil producing companies.
