Mineral Components on Heavy and Shale Oil Transformation
The mineral components of the reservoir system have a significant impact on the formation of hydrocarbon deposits. The composition of minerals changes with the migration of hydrocarbons during the further formation and destruction of the deposit.

Forward and Reverse Combustion
In situ combustion or fire flooding is a promising enhanced oil recovery (EOR) technique designed to produce heavy oils and bitumen. This method involves the in-place heating and combustion of hydrocarbons, resulting in reduced viscosity and increased mobility for improved flow toward the production wellbore. Despite its potential, widespread commercial implementation of in situ combustion has been hindered due to technical and economic challenges like inadequate project design and improper reservoir selection.

Influence of Axial Compressive Stress on Pipeline Network
Due to their exceptional structural integrity, steel pipelines are the main component for oil and gas transmission. However, these pipelines are often affected by corrosion, despite corrosion protection, because of harsh working conditions. In addition to corrosion defects, pipelines are often subjected to multiple external loads. The combination of corrosion defects and external loads can significantly reduce the failure pressure, resulting in various failure behaviors. This reduction in failure pressure is especially critical in pipe bends as they are the weakest link in a pipeline.

Fischer–Tropsch Synthesis Catalysts
The Fischer–Tropsch process is considered one of the most promising eco-friendly routes for obtaining synthetic motor fuels. Fischer–Tropsch synthesis is a heterogeneous catalytic process in which a synthesis gas (CO/H2) transforms into a mixture of aliphatic hydrocarbons, mainly linear alkanes. An important research direction has been to increase the selectivity of the process for the diesel fraction. Diesel fuel synthesized via the Fischer–Tropsch method has a number of advantages over conventional fuel, including the high cetane number, the low content of aromatic, and the practically absent sulfur and nitrogen impurities. One of the possible ways to obtain a high yield of diesel fuel via the Fischer–Tropsch process is the development of selective catalysts.

Produced Water Sustainability in Oil and Gas Sector
Oilfield produced water (PW) is the industry’s principal source of waste byproducts. Oil-producing countries, especially those with limited water resources, face significant difficulty in treating PW for recovery and reuse. Depending on its quality and content, PW can be treated using a variety of technologies. Numerous nations are currently undertaking substantial endeavors to ascertain efficacious and cost-effective treatment methodologies in order to rehabilitate their freshwater supplies. The compositions of pollutants play a major role in the selection of acceptable methods. According to the degree of contamination and the requirement for water quality, several treatment strategies can, therefore, be used. To successfully remove pollutants and/or lessen their detrimental effects on the environment, methods comprising physical, chemical, biological, and membrane treatments have been applied.

Fracture Characterization of Naturally Fractured Reservoirs
Recent developments in fracture characterization, modeling, and the impact of fracture networks on oil recovery in naturally carbonate-fractured reservoirs have been reviewed. The pivotal role of fracture identification and characterization in understanding production mechanisms and developing realistic fracture modeling approaches has been highlighted. This concludes that improved fracture network modeling requires considering various factors, such as data collection, fracture characterization, reservoir simulation, and model updating based on newly acquired field data. Integrating multiple techniques and data sources is recommended for obtaining a reliable reservoir model to optimize primary and enhanced oil recovery methods.

Approaches of Offshore Inspection
Operators of offshore production units (OPUs) employ risk-based assessment (RBA) techniques in order to minimise inspection expenses while maintaining risks at an acceptable level. However, when human divers and workers are involved in inspections conducted at high heights, the operational risks can be significant. There has been a growing trend towards the use of unmanned aerial vehicles (UAVs), autonomous surface vehicles (ASVs), remotely operated vehicles (ROVs), and autonomous underwater vehicles (AUVs) for inspections of offshore structures as a means to reduce exposure to human risk.
