What phenomenon caused the wettability to change from oil-loving to water-loving by hydrogel on pva base?5 answersThe phenomenon that caused the wettability to change from oil-loving to water-loving by a hydrogel on a PVA base is the alteration of wettability induced by the presence of surfactants in the drilling fluid. Specifically, the addition of nonionic surfactants like polyethylene glycol (PEG) in the water-based drilling fluids led to a change in the wettability of the reservoir rock from oleophilic to hydrophilic. This alteration in wettability was crucial in reducing formation damage and increasing oil production, as observed in carbonate reservoirs. The surfactants facilitated this change by interacting with the rock surface, causing it to shift from an oil-loving state to a water-loving state, ultimately enhancing reservoir productivity.
Why HYDrogel cant swell in heavy oil?5 answersHydrogels may struggle to swell in heavy oil due to various factors. In the context of oil recovery, hydrogel polymers are utilized for water control treatments in oil wells. However, heavy oil environments can pose challenges for hydrogel swelling due to factors like water salinity, temperature, and pH levels impacting the polymer system's properties. Additionally, the presence of heavy oil can affect the swelling behavior of hydrogels, potentially reducing their ability to absorb water and swell effectively. Moreover, innovative ion-responsive hydrogels have been proposed to address issues like cracks in oil well cement, which can hinder the functionality and durability of the cement sheath in heavy oil environments. These factors collectively contribute to the limitations of hydrogel swelling in heavy oil settings.
Is there any study about the spreading time of oil on hydrogel?4 answersThere is no study specifically mentioned in the abstracts about the spreading time of oil on hydrogel.
How can use hydrogel to water production?3 answersHydrogel can be used for water production in various ways. One method involves using hydrogel as a substrate conditioner to optimize water availability for seedling formation. By adding hydrogel to the substrate, it increases the total porosity and available water, allowing for a longer period between irrigations and improving the production system. Another application of hydrogel is in the field of solar-driven water evaporation. By fixing silver oxide/silver nanoparticles inside a hydrogel, the hydrogel can effectively degrade organic pollutants and increase the evaporation rate, providing a strategy for obtaining clean water from organic sewage. Additionally, hydrogel can be used as a super absorbent polymer to increase water holding capacity and efficiency in crop production. It can absorb large amounts of water and release it slowly, reducing irrigation frequency and water runoff, making it particularly useful in drought-prone areas.
How can hydrogels be used to clean up oil spills?5 answersHydrogels can be used to clean up oil spills by congealing the oil and facilitating its removal from the environment. Phase-selective organogelators (PSOGs) have been developed as a promising tool for oil spill remediation. These PSOGs can gel the oil in the presence of water/seawater, accelerating oil removal and reducing environmental impacts. Additionally, cellulose hydrogels have shown potential for removing water from diesel and biodiesel fuels. Different methods for hydrogel preparation, crosslinking induction, and drying were analyzed, and the hydrogels synthesized with cellulose and epichlorohydrin showed the best performance in removing water from the fuels. Furthermore, aerogels made from paper waste, crosslinking starch, and cellulose acetate have been investigated as sorbents for oil spills. These aerogels have high porosity and sorption capacity, making them effective in removing crude oil, marine diesel oil, and lubricating oil from water surfaces.
What is properties of glycerol in hydrogel?2 answersGlycerol has several properties in hydrogels.
