Abstract

A significant part of hydrocarbon reserves during development remains in the reservoir in the restrained volumes of the pore space. In depletion-mode formations, bypassed zones of hydrocarbons not affected by displacement can also form. The paper describes laboratory methods that can be used to estimate the amount of remaining restrained hydrocarbons and their distribution in the reservoir.
