Abstract

The influence of lithological factors on the formation of reservoirs in Neoproterozoic deposits was considered based on the deep drilling in the Lena-Anabar oil and gas region. It was established that the Precambrian section is represented by the alternation of packs of carbonate and terrigenous rocks and its accumulation took place in a large range of environments: from delta to sublittoral, with a significant prevalence of shallow-water sedimentation. It was discovered that potential reservoirs are present in Precambrian sediments, and the most perspective levels are related to the Vendian part of the section.
