.... Minimal changes are also observed in the sample's porosity. However, the small changes are due to the combination of dissolution and precipitation of the samples’ particles. Hence, despite a noticeable geochemical reaction during static ageing, F Field's samples can maintain their integrity because...

.... An an improved analysis on gas flow assurance can be done by conducting thermodynamic modeling of solid precipitation. The predicted solid precipitation where only observed at very extremely low temperature and pressure that unlikely to occur in operating condition of this field. In conclusion, proper...

... a calcium sulfate and strontium sulfate precipitation when sulfate content exceeded 300 ppm. Although 5,000 ppm of sulfate content showed theoretically a low scaling index of gypsum and celestine, the scale mass was estimated to be nearly 2,500 and 500 mg/L, respectively at equivalent mixing ratio. Also...

... due to the potential precipitation of the minerals ( Ahmad et al., 2023 ). Such precipitation can have detrimental effects on carbonate rock properties, including a reduction in rock porosity and permeability ( Labus & Suchodolska, 2017 ; Clark et al., 2018 ). Ultimately, these changes can impact...

... mobility and unique thermal properties. In this work, a comprehensive model of geothermal exploitation for depleted deep heavy oil reservoir via SCCO 2 injection was established, in which the process of heavy oil extraction, asphaltene precipitation on permeability were incorporated. Core displacements...

... recipes to assess performance. HCl acid and inorganic/organic acid retarded agents were obtained for this study. Typical experimental testing were conducted to assess acid recipes includes (1) thermal compatibility up to 300°F to identify precipitation or sludge formation, (2) iron control testing...

... of the chalk core pore space can occur. An analysis of precipitates formed during the injection of mixtures of produced water and seawater into a chalk core from the Danish North Sea was carried out, and an experiment with synthetic produced water is presented to identify the processes in the pore channels...

.... It was found that dissolution and precipitation of minerals occurred during and post CO 2 injection . The presence of small quantity of illite tends to decrease immensely the trapping capacity of CO 2 . Moreover, temperature and salinity tends to promote the mineral activity during CO 2 storage. This paper...

Combining the data from different techniques onsite and in laboratory assess the development of a methodology for calculating more accurate amounts of dissolved elements...

.... Also, the precipitation of metal fluorides, fluorosilicates, and so forth that may occur during acidizing will cause secondary damage to reservoirs. Therefore, we propose a new multiple chelating acid system (NMCAS) with low damage and weak dissolution. The system consists of multiple weak acids...
