Geofluids, Volume 2023, Issue 1, 2023., 2023 Stress sensitivity and the elastic outer boundary (EOB) condition have a great effect on the analysis of the characteristics of the fluid flow in a reservoir. When researchers analyzed the characteristics of the fluid flow, they have considered the stress sensitivity and the EOB condition separately but have not considered them simultaneously ...

Fluid Flow Behavior Prediction in Naturally Fractured Reservoirs Using Machine Learning Models
Complexity, Volume 2023, Issue 1, 2023., 2023 The naturally fractured reservoirs are one of the most challenging due to the tectonic movements that are caused to increase the permeability and conductivity of the fractures. The instability of the permeability and conductivity effects on the fluid flow path causes problems during the transfer of the fluids from the matrix to the fractures and fluid ...

GCB Bioenergy, Volume 14, Issue 6, Page 657-668, June 2022., 2022 According to a meta‐analysis, this study indicated that biochar amendment had a positive effect on soil hydraulic properties, and this effect could be influenced by soil conditions and biochar's properties. Moreover, structural equation models explained that biochar not only directly improved soil water supply, but also indirectly affected soil ...

The role of biochar particle size and hydrophobicity in improving soil hydraulic properties
European Journal of Soil Science, Volume 73, Issue 1, January–February 2022., 2022 Abstract The physical properties of biochar have been shown to dramatically influence its performance as a soil amendment. This study assessed the role of biochar particle size and hydrophobicity in controlling soil water movement and retention. Softwood pellet biochar in five particle size ranges (>2 mm, 2–0.5 mm, 0.5–0.25 mm, 0.25–0.063 mm and <0.063

Study on Developments in Protection Coating Techniques for Steel
Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 Steel, also known as iron alloy, is found 35% of the whole mass of the Earth. It is found in many applications due to its unique properties. Alloying elements provide the backbone support for iron, improving its mechanical, physical, chemical, and structural properties. Failure of steel is due to chemical reaction i.e., corrosion, and it is unavoidable,

Geofluids, Volume 2022, Issue 1, 2022., 2022 Offshore heavy oil reservoirs are developed mainly by inclined wells, and the well distance has been constantly reduced after several well network adjustments. The well test data are often interfered by adjacent wells, resulting in unsatisfactory well test interpretation results, so it is necessary to conduct studies on the multiwell interference well ...

Geofluids, Volume 2022, Issue 1, 2022., 2022 Dual‐permeability flow and stress sensitivity effect are two fundamental issues that have been widely investigated in transient pressure analysis for horizontal wells. However, few attempts have been made to simulate the combined effects of dual‐permeability flow and stress‐dependent fracture permeability on the pressure transient dynamics of a ...

Geofluids, Volume 2022, Issue 1, 2022., 2022 Fracture‐vuggy oil reservoirs contain micrometer‐sized dissolved secondary pores, fractures, and meter‐sized karst caves. Generally, the researches on the flow mechanism of fractured‐vuggy reservoirs are based on the assumption of karst cave‐fracture‐matrix triple medium that gives a partial differential equation which the pressure satisfies.

Geofluids, Volume 2022, Issue 1, 2022., 2022 This paper studies the influence of large‐size cave on pressure transient characteristics in fracture‐caved carbonate gas reservoirs (FCCGR). With the rapid increase of energy demand, the exploration and development of unconventional oil and gas becomes more and more important.
