This article contains detailed geological description and petrophysical modeling features of productive deposits in the Ust-Kutsky horizon of the North Danilovskoye Field of the Nepa-Botuoba Petroleum Province (NBP). The sediments have rather complex vertical distribution and variable reservoir properties. A complex of laboratory studies has been made and sedimentation-capacitive model of the pore space was developed according to the fact of the specific composition of sediments and facies heterogeneity. The presented approaches open up opportunities for the highest reservoir properties zones discovering.
