Typization of the Bazhenov Formation sections in the Nadym–Ob interfluve based on the interpretation of the well–log data

Abstract

As a result of the interpretation of the well–logging data, represented by electric, radioactive and acoustic logging, it was found that the Tarkosalinsky type of section of the Bazhenov Formation is wider in the western direction than was shown earlier and is also distinguished in the Apakapursky, Vengayakhinsky, Yaraynerskaya and South–Yarainerskaya areas, in the east of New Year's area. The Nizhnevartovsk type, on the contrary, has a narrower distribution and stands out directly within the arc of the same name.
