TL;DR: In this paper, an experimental and modeling work was performed to gain further insights into the geochemical interactions between carbonate rocks and modified brines, where single-phase static (equilibrium) and transport experiments were performed with various brines in limestone cores at 120°C.
101 citations
TL;DR: In this article, pH and ion concentrations including boron, calcium and sulfate were measured using an ion chromatograph (IC) and inductively coupled plasma (ICP) and they were found to maintain and propagate a high pH of more than 10 in the batch and transport experiments without significant permeability changes.
84 citations
TL;DR: In this paper, the authors investigate surfactant adsorption on a model carbonate rock over a wide range of pH and surfactants-to-solid ratios, by both an experimental and a theoretical approach, to obtain a quantitative understanding of how mineral constituents affect the adaption equilibrium and dynamics.

TL;DR: In this paper, a review of the literature available outside the petroleum industry concerning wettability is presented, including van der Waal and electrostatic forces, as well as hydrogen bonding and ion/water interactions.
Abstract: Review of the litterature available outside the petroleum industry concerning wettability. This litterature discusses surface forces and their effects on wettability, including van der Waal and electrostatic forces. Hydrogen bonding and ion/water interactions, are also discussed. Advancing and receding contact angles for oil/water/mineral systems in terms of these surface forces are described.

TL;DR: A comprehensive review of current research activities aiming at extending polymer flooding to high-temperature and high-salinity reservoirs is performed in this paper, which covers thermal stability, rheology, and adsorption behavior of various polymer systems in sandstone and carbonate reservoirs.
Abstract: Polymer flooding is one of the most promising techniques for the recovery of remaining oil from light oil reservoirs. Water soluble polymers are used to enhance the viscosity of displacing fluid and to improve the sweep efficiency. In this paper, water soluble polymers used for chemical enhanced oil recovery are reviewed. Conventional and novel modified polymers are discussed along with their limitations. The review covers thermal stability, rheology, and adsorption behavior of various polymer systems in sandstone and carbonate reservoirs. Field and laboratory core flooding data of several polymers are covered. The review describes the polymer systems that are successfully applied in low-temperature and low-salinity reservoirs. Comprehensive review of current research activities aiming at extending polymer flooding to high-temperature and high-salinity reservoirs is performed. The review has identified current and future challenges of polymer flooding.

TL;DR: In this article, the authors focused on the removal of arsenic from water using iron-based materials, such as iron nanoparticles, layered double hydroxides (LDHs), zero-valent iron (ZVI), iron-doped activated carbon, iron-depleted polymer/biomass materials, and iron-containing combined metal oxides.
Abstract: Intensive research efforts have been pursued to remove arsenic (As) contamination from water with an intention to provide potable water to millions of people living in different countries. Recent studies have revealed that iron-based adsorbents, which are non-toxic, low cost, and easily accessible in large quantities, offer promising results for arsenic removal from water. This review is focused on the removal of arsenic from water using iron-based materials such as iron-based nanoparticles, iron-based layered double hydroxides (LDHs), zero-valent iron (ZVI), iron-doped activated carbon, iron-doped polymer/biomass materials, iron-doped inorganic minerals, and iron-containing combined metal oxides. This review also discusses readily available low-cost adsorbents such as natural cellulose materials, bio-wastes, and soils enriched with iron. Details on mathematical models dealing with adsorption, including thermodynamics, kinetics, and mass transfer process, are also discussed. For elucidating the adsorption mechanisms of specific adsorption of arsenic on the iron-based adsorbent, X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS) are frequently used. Overall, iron-based adsorbents offer significant potential towards developing adsorbents for arsenic removal from water.
