Special Issue Information

Dear Colleagues,

Oil shale is an unconventional oil and gas resource that is listed as an especially important alternative energy resource in the 21st century for its rich resources and the feasibility of development and utilization. Due to the increasing demand for energy, theoretical research, exploration, exploitation, and utilization of oil shale have achieved fruitful results but also faced challenges. With the successful tests of high value-added utilization technology and in situ conversion technology of oil shale, oil shale scale development and utilization have shown broad potential for use in future fuels. In this Special Issue, we invite authors to submit original research and review articles addressing the geology, genesis, exploration, evaluation, mining, methods of processing and combustion, in situ conversion, economics and utilization of oil shale, as well as issues of environment problems.

Topics of interest for publication in this Special Issue include but are not limited to:

  • Genesis and metallogenic mechanism;
  • Exploration and resource evaluation;
  • Mining technology;
  • Composition and characteristics of oil shale;
  • Processing and combustion;
  • Economics and comprehensive utilization;
  • In situ conversion technology and challenges;
  • Oil shale’s environmental issues and challenges;
  • Socioeconomic impact and policy.

The stability of the casing is a crucial prerequisite for implementing the in situ high-temperature steam injection method in oil shale reservoirs. In order to address the issues of substantial expansion, concentrated thermal stresses, and susceptibility to damage observed in traditional straight casings under high temperatures, this paper proposes the utilization of a corrugated casing structure. In this regard, to investigate the impact of the shape and structure of the wellbore casing on its mechanical properties, identical corrugated and straight casings were selected and studied. Uniaxial compression and tensile tests were conducted on the casings, along with coordination deformation experiments between the casing and cement sheath under varying temperatures. Numerical simulations were employed to obtain the deformation characteristics of the corrugated and straight casings under axial compression and tension loads, as well as the stress distribution on the outer casing wall. The results showed that when subjected to the same amount of deformation under axial loading, the corrugated casing experienced lower compressive and tensile loads compared to the straight casing. Moreover, under the sole constraint of cement sheath, increasing the temperature led to lower vertical strains (perpendicular to the ground) at all measuring points of the corrugated casing as compared to the corresponding strains in the straight casing. Numerical simulations revealed that, under the same temperatures, the deformation at the interface between the corrugated casing and the cement sheath was smaller, while the vertical stress at the interface of the corrugated casing was also lower than the straight casing. Overall, the corrugated casing, with its corrugated structure that enabled micro-deformation, effectively mitigated the axial deformation of the casing caused by thermal expansion. Consequently, the corrugated casing reduced the extrusion of wellbore casing on the cement sheath, thereby preserving the integrity and stability of the wellbore cementing structure. Full article

The amount if oil shale resources throughout the world has been roughly estimated in accordance with various resource estimation methods. However, in some instances, detailed and comprehensive supporting methodologies for the estimation of commercial shale oil reserves have not been presented. The goal of this study is to develop a comprehensive method for the modified estimation of oil shale mineable reserves for shale oil projects. The methodology characterises oil shale according to its calorific value, oil content, conditional organic mass, and ash content by utilising a Monte Carlo simulation. Based on the results of the case study, the developed method proposes considering the relationships of the in situ oil shale grade and tonnage material (oil shale + limestone) to the oil retorting feed material grade and tonnage by taking into account the retorting plant oil recovery. For this purpose, a Monte Carlo stochastic modelling algorithm was developed. Based on the data analysis, a modifying factor to convert mineral reserves to petroleum reserves was produced. The results of this study are useful for feasibility studies that estimate oil shale reserves in relation to justifying their utilisation fields. Some oil shale deposits have good potential for development but need to be re-estimated in accordance with the most sophisticated extraction and processing technologies. Full article

Oil shale is an important unconventional oil and gas resource, but it is poorly utilized in the Dalianhe coal mining area, northeastern China. Systematic sampling and test analysis were used to evaluate the characteristics of oil shale quality. The research shows that the oil shale between the middle and lower coal seams in the coal-bearing member is a rich ore with a high oil content, medium calorific value, high ash content, medium volatile content, low moisture, and ultralow sulfur content. The oil shale has good quality and is suitable for low-temperature carbonization for oil refining or low-calorific fuel. The ash content is silicon–aluminum-rich, has low calcium–magnesium, is iron-poor, and has a high ash melting point. The middle oil shale member is a poor ore with low quality. However, there is a dense section of oil shale with a high organic matter content and good quality above the upper coal seam. It is recommended to implement combined mining of coal and oil shale in the mineshaft and to reasonably recover oil shale between the coal seams and oil shale above the upper coal seam to improve the resource utilization rate.
