The purpose of the research is to develop informative and stable geophysical criteria for identifying and evaluating the productivity of tight rocks-reservoirs of oil and gas. This is implemented on the basis of: studies of the most complete list of petrophysical properties and establishing their connection with effective geophysical parameters; development of the theory and methods of monitoring of formation intensification.

Relevance. The study of tight reservoir rocks addresses various natural and methodological challenges in laboratory and field settings to ensure the accurate acquisition, processing, and interpretation of geophysical data.
Objective. The project aims to develop informative and robust geophysical criteria for identifying and assessing the productivity of tight oil and gas reservoirs. This involves investigating a comprehensive range of petrophysical properties, establishing their correlation with effective geophysical parameters, and developing a methodology for monitoring formation stimulation processes.
Tasks.
Conduct comprehensive laboratory petrophysical studies of tight reservoir samples, accounting for anisotropy and fluid saturation.
Develop a database architecture for laboratory research results.
Ideas and Hypotheses. Unconventional hydrocarbon reservoirs possess unique petrophysical properties, such as low porosity, low permeability, and specific responses to compression under multiphase saturation. In low-permeability reservoirs, residual and critical water saturation levels vary significantly between objects. Consequently, there is a wide range of saturation where fluid migration is impossible. In extreme cases (ultra-low permeability), a mobile water phase is virtually absent even at high saturation levels, rendering the rock impermeable to both gas and water. However, hydrocarbon saturation alters the physical properties of the accumulation, creating a contrast in petrophysical parameters and geophysical fields relative to the host rocks, which enables their geophysical detection and study.
