Раннепермские органогенные постройки севера Тимано-Печорского бассейна

Lower Permian organogenic buildups within the Northern part of Timan-Pechora basin are mounds-type structures. They are characterized by an extremely irregular distribution of reservoirs which are linked to facial zones and genetic features of the deposits. Two types of buildups were distinguished qualified as microbial and skeletal mounds formed by different paleo-communities of benthic organisms. The composition and textural-structural features of prevailing limestones within these buildups there is a key to understand the distribution of reservoirs within the area of study.
