About this Research Topic
In recent years, with the continuous development and depletion of conventional oil and gas reservoirs, the exploration of unconventional oil and gas has gradually become a new hot spot and challenge in the oil and gas industry. Unconventional oil and gas refer to the oil and gas resources that cannot be extracted using traditional technology under normal industrial conditions and can only be economically exploited by employing new technologies to improve rock or fluid properties. Common unconventional sources include tight sandstone oil and gas, shale oil and gas, heavy oil, coal bed methane, and natural gas hydrates. Given these contexts, accurate petrophysical evaluations can provide crucial support for the exploration and development of unconventional oil and gas. Therefore, it is essential to be aware of and familiar with the advances in this field.
How can advanced experimental equipment, methods, and models be used to solve the current key problems in the accurate evaluation of unconventional oil and gas reservoirs? These problems include, but are not limited to:
1. How can accurate evaluation of rock skeleton parameters be achieved? Skeleton parameters include mineral content, mineral distribution, skeleton density, skeleton structure, and rock mechanical properties.
2. How can an accurate description of pores and fractures be achieved? Pore-fracture parameters include porosity, permeability, fracture morphology, fracture distribution characteristics, pore-fracture connectivity, and tortuosity.
3. How can accurate evaluation of fluid properties be achieved? Fluid properties include oil, gas, and water content, fluid density, fluid viscosity, and the occurrence state of the fluid.
4. How can a dynamic evaluation of petrophysical parameters be achieved? In other words, how do petrophysical parameters evolve dynamically with fluid migration and pressure changes during oil and gas development, and what impact do they have on reservoir characteristics?"
We invite researchers to submit original research articles, case studies, and review papers that address significant challenges in the petrophysical characterization of unconventional oil and gas. We hope these papers will stimulate ongoing efforts to develop innovative petrophysical methods and techniques, thereby driving breakthroughs in the exploration and development of unconventional oil and gas resources.
