Abstract Generating hydraulic fractures with good conductivity is essential for well productivity in unconventional formations. However, gradually lose hydrocarbon production as fracture surfaces creep closer due to proppant embedment or failure of asperities under increasing effective in-situ stresses and high temperatures. This work proposes adding a widely available, natural-based ground calcium carbonate (GCC) fracturing treatments formations make mechanically harder enhance long-term...

Abstract To avoid air pollution and global warming correlated with utilize utilizing fossil fuels to produce hydrogen. Developing new renewable technologies for generating H2, such as photoelectrochemical water splitting, is undoubtedly important the future of this clean energy carrier. In fact, most H2 today produced from steam-reforming methane, which produces environmentally, health hazard gases, CO2. address critical challenge, researchers tend generate by a promising alternative method...

Hydrogen is a carrier energy gas that can be utilized as clean source instead of oil and natural gas. Splitting the water into hydrogen oxygen one most favorable methods to generate hydrogen. The catalytic properties molybdenum disulfide (MoS 2 ) could valuable in this role, particularly due its unique structure ability chemically modified, enabling activity further enhanced or made comparable Pt-based materials. In general, these modification strategies may involve either structural...

Abstract Neutral wet proppant plays a pivotal role in maximizing the flow back of fracturing fluids and recovery produced hydrocarbons. An accurate repeatable contact angle measurements are extremely challenging because spherical shape small size. This paper presents methodology direct particles examined with high strength coated ceramic proppant. 20/40 25 HSP non proppants were used for study. Coating material was applied to sample obtain non-wetting characteristics. KRUSS Drop Analyzer...

However, gradually lose hydrocarbon production as fracture surfaces creep closer due to proppant embedment or failure of asperities under increasing effective in-situ stresses and high temperatures. This work proposes adding a widely available, natural-based metal carbonate (MC) fracturing treatments formations make mechanically harder enhance long-term...

Abstract Undesired water production is the most common problem of oil and gas wells. Oil may be restricted because high producing fluid levels commonly associated with production. In 2000, Bailey et al. reported that 3 barrels were produced for each barrel oil, amounting to about 75 billion at time. The economic lives many wells are shortened excessive cost These expenses include lifting, handling, separating, disposing an estimated $40 billion. need shut off unwanted entire well's life...

Abstract Excessive water production is one of the significant phenomena reservoirs worldwide that influence oil and costs. At same time, a comprehensive collection treatments available to solve this issue, such as mechanical shutoff, polymer-based gel, crosslinkers-based gel. However, they all possess drawbacks, including but not necessarily limited surface mixing handling problems. Foamed gel systems can enhance by plugging high permeability zones due their physical plugging, adsorption,...

Hydrogen appears as a next-generation clean energy source to replace fossil fuels. One of the most promising ways produce hydrogen is water splitting using photoelectrochemical (PEC) cell. Silicon widely used in this cell due its viability absorb light. However, efficient catalysis and long-term stability remain key challenges corrosion effect.
