Summary:
Hydrocarbon reserves related to the basement were discovered in each part of the world. The interpretation of logging and petrophysical data obtained from complex reservoirs, in particular the fractured metamorphic rocks, is a challenging task which is as relevant as evaluating the associated hydrocarbon recovery prospects. From the perspective of petrophysical study and forecast promising areas is evolving. The Paleozoic rock has three main types of cavitation: fractures, caverns and the hollow zones of disintegrated rock. There is no clearly defined method for identifying pay zones and their properties using standard techniques. In this work authors tried to summarize their experience in characterization of fractured Paleozoic reservoirs. Different methods and techniques were implemented, compared and become a part of an integrated petrophysical-geomechanical workflow.
