Mechanical Characterization of Low Permeable Siltstone under Different Reservoir Saturation Conditions: An Experimental Study

open access: yesEnergies, 2018
Hydro-fracturing is a common production enhancement technique used in unconventional reservoirs. However, an effective fracturing process requires a precise understanding of a formation’s in-situ strength behavior, which is mainly dependent on the ...

Determination of Bromine in Brine by Wavelength Dispersive X-ray Fluorescence Spectrometry with Film Adsorption Pretreatment

open access: yesYankuang ceshi, 2015
Bromine exists mainly as ions in bromide brine and halide sulfate brine in the hydrosphere of the crust. Powder carrier pellet method is commonly used in analyzing bromine in brine by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). However,

Constraining the potential liquid water environment at Gale crater, Mars [PDF]

open access: yesRivera-Valentin, E. G., et al. (2018) Constraining the potential liquid water environment at Gale crater, Mars. Journal of Geophysical Research: Planets, 123, 1156-1167, 2018
The Mars Science Laboratory (MSL) Rover Environmental Monitoring Station (REMS) has now made continuous in-situ meteorological measurements for several martian years at Gale crater, Mars. Of importance in the search for liquid formation are REMS' measurements of ground temperature and in-air measurements of temperature and relative humidity, which is ...

Flow-electrode capacitive deionization enables continuous and energy-efficient brine concentration [PDF]

open access: yes, 2022
Many industrial and agricultural applications require the treatment of water streams containing high concentrations of ionic species for closing material cycles. High concentration factors are often desired, but hard to achieve with established thermal or membrane-based water treatment technologies at low energy consumptions.

Comparing carbon sequestration in an oil reservoir to sequestration in a brine formation-field study [PDF]

open access: yes, 2008
Geologic sequestration of CO2 in an oil reservoir is generally considered a different class than sequestration in formations which contain only brine. In this paper, the significance and validity of this conceptualization is examined by comparing the ...
