| Selected issues in the petrophysical study of volcanoclastic rocks of the pre-Jurassic strata West Siberian petroleum basin | |
| This article examines current issues in the study of the pre-Jurassic volcanoclastic strata, using the example of a developing field located in the West Siberian petroleum basin. The focus is on methods for determining petrophysical parameters involved in assessing hydrocarbon resource potential and forecasting development. Methods for calculating the capacitive properties of volcanic rocks and substantiating reservoir boundary values using statistical criteria are proposed. Particular emphasis is placed on finding a solution to the problem of quantitatively assessing oil saturation in the absence of stable relationships between the nature of rock saturation and its electrical resistivity, due to the structural features of the void space. Keywords: volcanogenic-clastic rocks, pre-Jurassic strata, quantitative assessment of oil saturation, West Siberian petroleum basin. |

| Evaluation of the mobile oil amount in the pores space of unconventional reservoirs associated with mature source rocks, by laboratory methods | |
| The issues of methodological support of the so-called unconventional petroleum reservoirs are considered. The reserves calculation and development forecasting for them are impossible within the framework of the traditional concepts of petroleum geology, also hydrodynamics. Proposed approach of the net pay identifying and resource estimation does not rely on the traditional definition of reservoir rock and the permeability cutoff. It is based on evaluation of the mobile oil amount that could be potentially involved in to development under the conditions of using modern technologies for creating artificial reservoir permeability by hydraulic fracturing. The article is limited to the planning of laboratory core testing and results processing. It does not concern methods well logging data evaluation, which require a separate discussion. Keywords: unconventional petroleum reservoirs, petroleum source rock, pore space, mobile oil amount, laboratory core testing. |
