Zeta potential has been proposed as a key parameter for predicting the response of controlled salinity waterflooding, correlation with additional oil recovery previously established. However, it is unclear if there causal effect and this can be used unique predictive tool. We provide new insights detailed investigation into role change polarities oil/water/rock interfaces on recovery. Core floo...

The central rift of the Red Sea has 25 brine pools with different physical and geochemical characteristics. Atlantis II (ATIID), Discovery Deeps (DD) and Chain Deep (CD) are characterized by high salinity, temperature and metal content. Several studies reported microbial communities in these brine pools, but few studies addressed the brine pool sediments. Therefore, sediment cores were collecte...

The precipitation of calcium carbonate and calcium sulphate by isolated bacteria from seawater and real brine obtained in a desalination plant growth in culture media containing seawater and brine as mineral sources has been studied. However, only bioprecipitation was detected when the bacteria were grown in media with added organic matter. Biomineralization process started rapidly, crystal for...

In recent years, geothermal energy use from low-temperature sandstone reservoirs has sharply increased. Nonetheless, the injection of heat-depleted fluids not been an easy task because well/formation damage and operational/economic issues. Sønderborg plant is a case example heat-mining reservoir. It in northeast towards Augustenborg Fjord. The present work takes into consideration regional loca...

Convective mixing of dissolved carbon dioxide (CO2) with formation brine has been shown to be a significant factor for the rate of dissolution of CO2 and thus for determining the viability of geological CO2 storage sites. In most previous convection investigations, a no-flow boundary condition was used to represent the interface between an upper region with CO2 and brine and the single-phase br...

6 A two-dimensional model of a passive continental margin was adapted to 7 the simulation of the methane cycle on Siberian continental shelf and 8 slope, attempting to account for the impacts of glacial / interglacial 9 cycles in sea level, alternately exposing the continental shelf to freezing 10 conditions with deep permafrost formation during glacial times, and 11 immersion in the ocean in i...

To evaluate the gas production performance of the hydrate accumulations in the South China Sea, a numerical simulation with warm brine stimulation combined depressurization has been conducted. A dual horizontal well system is considered as the well configuration in this work. In order to reduce energy input and improve energy utilization, warm brine (<30 °C) instead of hot brine (>50 °C) is inj...

There is an increasing need for the desalination of high concentration brine (>TDS 35,000 ppm) efficiently and economically, either for the treatment of produced water from shale gas/oil development, or minimizing the environmental impact of brine from existing desalination plants. Yet, reverse osmosis (RO), which is the most widely used for desalination currently, is not practical for brine de...

We explore theoretically the controls on dissolution of salt A, in an under-saturated brine of salts A and B. We show that, as the concentration of B increases, the dissolution rate of A decreases, for brine of given temperature. We also show that there is a sharper decrease in dissolution rate with increasing concentration, for concentrations of B above a critical value, where B limits the equ...

The demand for “green” metals such as lithium is increasing the world works to reduce its reliance on fossil fuels. More than half of world’s resources are contained in lithium-brine deposits, including salt flats, or “salars”, Andean region South America, also known Lithium Triangle. genesis deposits largely driven by leaching from source rocks watersheds, transport via groundwater systems sal...
