Water flooding is one of the most influential methods for pressure maintenance and enhanced oil recovery. However, water flooding is likely to develop the formation of oilfield scale. Scale formation in reservoirs, due to the mixing of injection water and formation water, could cause formation damage and production limit. Therefore, it is necessary to simulate the compatibility of brine and inj...
the present study was designed to assess the cytotoxicity, anti-inflammatory and analgesic properties of methanol extract of woodfordia fruticosa flowers. cytotoxic activity of methanol extract of woodfordia fruticosa flowers was tested using artemia salina (brine shrimp) bioassay. two doses (400 and 600 mg/kg) were evaluated for the anti-inflammatory activity against the carrageenan, histamine...
An ancient Martian hydrosphere consisting of an alkali-rich ocean would likely produce solid carbonate minerals through the processes of evaporation and/or freezing. We postulate that both (or either) of these kinetically-driven processes would produce carbonate minerals whose stable isotopic compositions are highly fractionated (enriched) with respect to the source carbon. Various scenarios ha...
[1] Cross-borehole DC resistivity tomography has recently been used to monitor the temporal variation of the anisotropic bulk electrical resistivity of first-year Arctic sea ice during the period of spring warming. These measurements cannot be explained by standard models of sea ice microstructure which treat the brine phase as isolated ellipsoidal pores. A simple structural model which does sa...
This study explored the bacterial diversity of brines used for cheesemaking in Italy, as well as their physicochemical characteristics. In this context, 19 brines used to salt soft, semi-hard, and hard Italian cheeses were collected in 14 commercial cheese plants and analyzed using a culture-independent amplicon sequencing approach in order to describe their bacterial microbiota. Large NaCl con...
Understanding the freezing of salt solutions near solid surfaces is important in many scientific fields. Here we use sum frequency generation (SFG) spectroscopy to study the freezing of a NaCl solution next to a sapphire substrate. During cooling we observe two transitions. The first corresponds to segregation of concentrated brine next to the sapphire surface as we cool the system down to the ...
Great Salt Lake, Utah, is a large, terminal, hypersaline lake consisting of a northern more saline arm and a southern arm that is less saline. The southern arm supports a seasonally abundant fauna of low diversity consisting of brine shrimp (Artemia franciscana), 7 species of brine flies, and multiple species of algae. Although fish cannot survive in the main body of the lake, the lake is highl...
A small but significant number of sinkholes and other karst phenomena in southeastern New Mexico are of human origin and are often associated with solution mining of salt beds in the shallow subsurface. In 2008 two brine wells in a sparsely populated area of northern Eddy County, New Mexico, abruptly collapsed as a result of solution mining operations. The well operators had been injecting fres...
Large quantities of oil and gas well brines are produced annually in Ohio. This paper presents chemical parameters measured for a Wayne County, Ohio, oil well brine and reports the effects of several incremental brine concentrations on the germination and seedling development of soft red winter wheat (Triticum aestivum), soybeans (Glycine max), tall fescue (Festuca arundinacea), garden peas (Pi...
Evidence for deliquescence of perchlorate salts has been discovered in the Martian polar region while possible brine flows have been observed in the equatorial region. This appears to contradict the idea that bulk deliquescence is too slow to occur during the short periods of the Martian diurnal cycle during which conditions are favorable for it. We conduct laboratory experiments to study the f...
