... understanding of CO 2 solubility under deep saline aquifers. However, sparse studies have delved into the real reservoir brine, consisting of complex salt ions. Also, few works have been done focusing on CO 2 geo-sequestration applications. In this work, we develop a practical and robust CO 2 solubility...

... with partial 2-acrylamido tert-butylsulfonic acid (ATBS) substitution Testing was performed in multiple water qualities with varying salinities and pH levels. The study revealed that particle bridging of fines by cationic polymers to the proppant pack is more strongly affected by the salinity than anionic...

... Abstract Injected water salinity is usually a function of cost and availability and only evaluated to avoid formation damage rather than designed to increase recovery. In this paper we present experimental results for the alteration of wettability by water salinity from the Wolfcamp...

From base to top is composed of Paleogene units, that have been intensively characterized since many of these are part of the petroleum system of the basin. However, Neogene and Quaternary units are also present but have not been studied...

Using the measured clay-bound water (VCBW) from the NMR, a dual water CRIM dielectric inversion water volume model was developed that compensates for the difference between the salinities...

.... Formation water salinity is one of the most important inputs in the calculation of fluid saturations. During early-stage exploration, formation water salinity in the target reservoir is typically unknown, which brings large uncertainty to resulting petrophysical evaluations. In such cases, fluid inclusions...

... Abstract The research goal is the development of a novel integrated solution of formation water content and salinity determination for petrophysical characterization. The workflow relies on three techniques: evaporation method (EM) with isotopic composition analysis, analysis of water extracts...
