...-effective due to the high TDS content and volumes of these waters. Moreover, TDS reduction might be required to ensure that reused produced water does not block the apertures created by hydraulic fracturing because blockages due to the precipitation of TDS in the fractures will consequently lower...

.... Oilfield scales hinder assessing an optimum hydrocarbon production as their precipitation on formation, various surface, and downhole equipment leads to many problems, including pressure decrement, formation damage, and operational failure of subsurface equipment. One type of these scales is the iron...

... It is noted that many of the heavy oils represented in the dataset have asphaltic components that can precipitate when mixed with light paraffinic solvents. The amount of precipitation experienced by a solution can strongly affect viscosity. No attempt was made in this work to directly model...

... rate of about 175 MSCFD. Due to the rise of water contact above the intersection of pilot injector with reservoir top and an initial relatively low injection rate, the evaluation of capillary-driven backflow on salt precipitation and eventually on CO 2 injectivity becomes a necessity. The simulation...

.... Emulsified acids suffer from emulsion instability issues at higher temperatures making them susceptible for sludge and asphaltene precipitation like their parent acid. Chelating agents have emerged as attractive candidates for high temperature matrix stimulation in past few decades. The term ‘chelating...

.... The pressure drop in this tool induces the flash liberation of CO 2 from the aqueous solution. Consequently, the chemical equilibrium is displaced towards the direction of precipitation of CaCO 3 in the flow stream. This paper proposes a new approach to predict scaling in downhole conditions and aims...

... of scale formation in the wellbore. Sulfate concentrations can be reduced by mixing AMD with flowback, which has high concentrations of barium (Ba 2 +) and strontium (Sr 2 +). Sulfate will react with the barium and strontium to precipitate barite (BaSO 4 ) and celestite (SrSO 4 ) which can be removed from...

... In the event of asphaltene supersaturation, either from the solvent becoming worse or the addition of too much solute, the asphaltenes will precipitate. As is often the case with supersaturated solutions, the asphaltenes can undergo "heterogeneous nucleation". That is, the excess asphaltene can...

..., formation and fracturing fluids lead to precipitations which reduce porosity. Under in-situ conditions, these interactions further facilitate the phenomenon of geo-chemical diagenesis as a result of which rapid loss of fracture conductivity is observed. The diagenesis process includes mechanisms...
