Technological and Legislative Impacts on Automotive Sector Development
Land transport activities play an essential role within our society. At the same time, these activities generate directly huge amounts of pollutants due to vehicle operation, and indirectly, more pollution due to vehicle production and recycling as well as a significant consumption of energetic resources and raw materials. Looking back into the cars history, one can notice how their technological development was correlated with the socio-economic, environmental, and health context, and has paved the way for new policies and strategies for exploiting the available energy sources and materials with respect to the current automotive regulations.

Electrical Resistance Tomography  in Oil and Gas Reservoirs
Petroleum engineers need real-time understanding of the dynamic information of reservoirs and production in the development process, which is essential for the fine description of oil and gas reservoirs. Due to the non-invasive feature of electromagnetic waves, more and more oil and gas reservoirs have received attention to capture the development dynamics with electrical resistance tomography (ERT). By measuring the distribution of resistivity on the surface, the ERT can offer information on the subsurface media.

Gels for Conformance Control and Flow Diversion
The use of hydrogels in the development of oil fields by the flooding method has firmly established itself in the oil industry, and this direction is constantly evolving in all oil-producing countries around the world, as evidenced by the growth of publication and patent activity on this topic. Operations for conformance control and flow diversion are impossible to imagine without the use of gel technologies today. Inorganic, organic, and hybrid gels, as well as foam gels, gel-forming and gel-dispersed systems are used. The ability to widely regulate structural-mechanical properties, thermal stability, and shear resistance through the introduction of micro- and nano-sized additives has made hydrogels indispensable tools for petroleum engineers.

Shale Oil Occurrence Mechanisms
Shale oil resources are important supplements for the gradually decreasing oil production from conventional reservoirs. The exploitation and development of shale oil have achieved considerable progress, the commercial extraction of hydrocarbons from shales is still difficult, especially in the lacustrine sedimentary basins of China.

CO2 Enhanced Oil Recovery
CO2 enhanced oil recovery is a tertiary petroleum recovery process in which carbon dioxide is injected into a depleted oil reservoir to mobilize residual oil that cannot be displaced by primary production or secondary waterflooding. Under sufficient reservoir pressure and temperature conditions, injected CO2 becomes miscible or near-miscible with the crude oil, reducing oil viscosity, swelling the oil phase, and lowering interfacial tension so that oil flows more readily toward production wells [1]. The process operates through mechanisms of multi-contact miscibility development, where CO2 transfers between gas and oil phases across a transition zone and progressively extracts lighter hydrocarbons from the oil, progressively altering the phase behavior until the gas and oil become single phase at the minimum miscibility pressure. Reservoir engineering design determines injection patterns, slug size, WAG (water-alternating-gas) ratios, and reservoir pressure to optimize sweep efficiency while controlling gravity override, viscous fingering, and CO2 breakthrough. The process simultaneously serves as a carbon storage mechanism because a portion of the injected CO2 remains sequestered in the reservoir after field operations cease, making it a bridge between production and geologic storage objectives [2]. The key technical parameters are minimum miscibility pressure, MMP, minimum miscibility enrichment, residual oil saturation after waterflooding, and the storage capacity determined by pore volume and displacement efficiency [3].
