Identification of low permeability zone based on well log data within Lower Carboniferous strata (DDB)

Carboniferous strata is referred to the interval where unconventional oil and gas deposits can be formed. They controlled by the high temperatures and pressures which influence secondary alterations in seal and reservoir rocks. Meanwhile this zone is characterized by abnormal pressure occurrence so its further prediction is important to avoid unexpected accidents during exploration and production works on the well site.
