Special Issue Information

Dear Colleagues,

In order to address global energy demands amidst declining conventional reserves, it is now crucial to develop unconventional hydrocarbon resources, including shale gas, tight oil, oil sands, and coalbed methane. Meanwhile, more and more countries are looking to promote sustainability. Despite the global reserves of unconventional oil and gas far exceeding those of conventional resources, the global production of unconventional resources remains low, and technical challenges are often encountered when aiming to sustainability explore and exploit these resources.

This Special Issue aims to present the novel technologies and methods developed for the evaluation and exploitation of unconventional oil and gas. We welcome interested authors to submit original research and review articles that address the sustainable development of unconventional oil and gas resources, unconventional energy extraction technology, and hydraulic fracturing-induced earthquakes.

The scope of this Special Issue includes, but is not limited to, the following topics:

  1. Sustainable development methods for unconventional oil and gas resources.
  2. New technology and theories regarding unconventional oil and gas exploitation and exploration processes.
  3. New geophysical methods for unconventional oil and gas exploration and development, especially induced earthquakes, seismic risk assessment, etc.
  4. New technologies and methods for enhancing the sustainable development of unconventional oil and gas reservoirs.
  5. The application of artificial intelligence methods for unconventional oil and gas exploration and development.
  6. New theories and methods for geothermal energy development.

Flue gas is an industrial waste gas produced by the combustion of fossil fuels. Its application in reservoir development can increase oil recovery factor and achieve underground storage of CO2. Flue gas gravity flooding experiments were conducted to clarify the displacement and storage characteristics of flue gas gravity flooding. The results show that the experiment can be divided into three stages based on the output characteristics, and the oil recovery factor curve exhibits a stepwise increase. During the pure oil production stage, the crude oil output is approximately half of the total output. When the experimental pressure is 18 MPa, the oil recovery factor is 11.53%. As the experimental pressure increases, the extraction and viscosity reduction effects of the flue gas are enhanced. Therefore, the oil recovery factor gradually increases and the crude oil in the micropores and small pores is better displaced. The storage rate of flue gas is 8.42% at a pressure of 18 MPa. When the experimental pressure increases to 25 MPa, the storage rate of flue gas reaches 19.70%. The increase in permeability and the extension of displacement time can effectively improve the oil recovery factor. The research results provide a new approach for the resource utilization of flue gas and offer theoretical support for flue gas flooding in tight reservoirs. Full article
