| 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. |
