TL;DR: In this paper, the effect of temperature and pressure on carbonate and calcium carbonate scale formation in high pressure and high temperature reservoirs has been investigated, and the scaling tendency of the carbonate scaling brines was found to decrease as pressure was increased.

TL;DR: In this paper, the reaction of carbon dioxide (CO 2 ) with brine samples collected from the Oriskany Formation in Indiana County, PA, was investigated in an autoclave reactor under various conditions.

TL;DR: In this paper, both S-1 and ZSM-5 membranes were tested using a pervaporation set up for the desalination of aqueous solutions containing NaCl in concentrations corresponding to brackish (0.3-1 wt), sea (3.5 wt%), and brine (7.5-15 wt%) water.

TL;DR: In this paper, the dc conductivity and complex dielectric constant at frequencies of 7.50, 9, 11, 30, and 40 GHz of 16 samples of sea water brine in equilibrium with sea ice with freezing temperatures ranging from - 2.8\deg C to -25.0
Abstract: The dc conductivity and complex dielectric constant at frequencies of 7.50, 9, 11, 30, and 40 GHz of 16 samples of sea water brine in equilibrium with sea ice with freezing temperatures ranging from - 2.8\deg C to -25.0\deg C have been measured. The data is analyzed to yield parameters occurring in a Debye relaxation equation so that the dielectric constant of brine may be calculated throughout the microwave region of the electromagnetic spectrum.

TL;DR: In this paper, a high molecular weight (>106) copolymer of N,N-dimethyl acrylamide with Na-2-acrylamido 2-methylpropanesulfonate (NNDAM-NaAMPS) was prepared and characterized.
Abstract: A high molecular weight (>106) copolymer of N,N-dimethyl acrylamide with Na-2-acrylamido-2-methylpropanesulfonate (NNDAM-NaAMPS) was prepared and characterized. The efficacy of the copolymer as an enhanced oil recovery (EOR) chemical was studied. Core flood tests using 72−150 mesh size unconsolidated sand having a porosity of 42% were carried out at different brine concentrations and temperatures. Initially, a crude oil fraction (150−300 °C) and, finally, the crude itself were used as the oils to be recovered. The copolymer was brine compatible. After a water flood, about 5.6% original oil in place (OIP) could be recovered by injecting 2000 ppm polymer solution to the sand pack containing oil fraction and 5000 ppm NaCl brine. The polymer solution was found to be thermally stable at 120 °C at least for a period of 1 month. It was further confirmed that the residual oil recovery increased with the increase of temperature. About 11% of OIP could be recovered as additional oil by injecting a 2000 ppm polymer ...
