This paper establishes an analytical model to study the influence mechanism of hydraulic
fracturing around vertical wellbores under the unsteady seepage in hydrocarbon reservoirs …

Due to the heterogeneity of the pore structure, there is still much residual fossil hydrogen
energy in the pore space. In this study, the distribution of residual fossil hydrogen energy …

The polymer fracturing fluid has been gradually used in the fossil hydrogen energy field.
However, its impacts on the fields are still unclear. In this study, a series of experiments were …

Vertical wells large scale fracturing and stimulated reservoir volume (SRV) treatments is an
important method to enhance productivity of shale gas wells. Since the existence of micro …

Surfactant huff-n-puff can enhance fossil hydrogen energy recovery from low permeability
reservoirs. However, due to the high cost and adsorption of surfactant, its commercial …

Shale gas resources (SGR), as a representative of natural gas hydrate reservoirs, have
been the main energy supply for the energy consumption currently. The multi-scale pore …

The hydraulic fracturing is extensively used to stimulate the production of fossil hydrogen
energy. Perforation parameters have a great influence on the performance of hydraulically …

Hydraulic fracturing is an important process to increase the productivity of wells. In shallow
reservoirs, tectonically active reservoirs, and abnormally high-pressure reservoirs, fractures …

Faced with dwindling fossil fuel reserves, enhancing energy recovery and transitioning to
renewables is essential. In tight reservoirs, electrochemical effects of micro and nanopores …

In this study, a mixed numerical model is established to simulate the production performance
of gaseous compound of hydrogen and carbon in shale reservoir. Estimated ultimate …
