... investigated CO 2 /brine IFT as a function of several variables e.g., pressure, temperature, salinity, salt composition and presence of impurities [ 10 , 27 , 30 , 32 , 35 , 36 , 41 – 60 ]. The consensus is that IFT decreases with pressure while it increases with temperature, salinity, and impurities present...

... with the dynamic Lorenz coefficient. Alongside a homogeneous model, four models with increasing heterogeneity (DLc values of 0.2, 0.4, 0.6, and 0.8) were analyzed. Sensitivity analyses were conducted on factors such as water salinity, wettability, injection rate/volume, and completion interval. Depending...

... representative results of the formation. The formation Cl concentration was combined with the water volume derived from PN carbon/oxygen ratio analysis to compute the water salinity and obtain a formation salinity profile along the reservoir. This is particularly useful in fields subjected to water injection...

... The 1 st sequence of the phase has resulted into unexpected low oil gain. The team has investigated the causes via revising the injection profile and data gathering. It was apparent that the increase of water injection salinity has impacted the functionality of the surfactant. The following...

... Abstract Addressing global climate change necessitates innovative solutions for carbon capture and storage (CCS). With their vast capacities, saline aquifers emerge as promising repositories for CO 2 sequestration. While solubility is the primary trapping mechanism for CO 2 in saline aquifers...

...) determination is well known, preparing a unique low salinity single-well pilot design, under High temperature (HT) above 250 °F and High salinity (HS) above 260g/l TDS conditions of Reservoir X, required a novel scope of work and strategy. Tasks included: Well candidate selection and recompletion strategy...

... on dielectric properties of multiphase mixture can be implemented without moving parts, but the dielectric properties have highly non-linear and non-monotonic response with respect to salinity of the produced water, making it extremely complicated to implement. That is why, existing dielectric based MPFM also...

... Abstract The effects of the DO concentration and salinity on corrosion behaviour of carbon steel were investigated by electrochemical measurements to estimate corrosion rate simulating ruptured subsea pipeline. Corrosion rates decreased as the DO concentration decreased. When the salinity...
