Low salinity waterflooding is an emerging enhanced oil recovery (EOR) technique in which the salinity of the injected water is substantially reduced to improve oil recovery over conventional higher salinity waterflooding. Although there are many low salinity experimental results reported in the literature, publications on modeling this process are rare. While there remains some debate about the mechanisms of low salinity waterflooding, the geochemical reactions that control the wetting of crude oil on the rock are likely to be central to a detailed description of the process. Since no comprehensive geochemical-based modeling has been applied in this area, we decided to couple a state-of-the-art geochemical package, IPhreeqc, developed by the United States Geological Survey (USGS) with UTCOMP, the compositional reservoir simulator developed at the Center for Petroleum and Geosystems Engineering in The University of Texas at Austin. A step-by-step algorithm is presented for integrating IPhreeqc with UTCOMP. Through this coupling, we are able to simulate homogeneous and heterogeneous (mineral dissolution/precipitation), irreversible, and ion-exchange reactions under non-isothermal, non-isobaric and both local-equilibrium and kinetic conditions. Consistent with the literature, there are significant effects of water-soluble hydrocarbon components (e.g., CO2, CH4, and acidic/basic components of the crude) on buffering the aqueous pH and more generally, on the crude oil, brine, and rock reactions. Thermodynamic constrains are used to explicitly include the effect of these water-soluble hydrocarbon components. Hence, this combines the geochemical power of IPhreeqc with the important aspects of hydrocarbon flow and compositional effects to produce a robust, flexible, and accurate integrated tool capable of including the reactions needed to mechanistically model low salinity waterflooding. The geochemical module of UTCOMP-IPhreeqc is further parallelized to enable large scale reservoir simulation applications. We hypothesize that the total ionic strength of the solution is the controlling factor of the wettability alteration due to low salinity waterflooding in sandstone reservoirs. Hence, a model based on the interpolating relative permeability and capillary pressure as a function of total ionic strength is implemented in the UTCOMP-IPhreeqc simulator. We then use our integrated simulator to match and interpret a low salinity experiment published by Kozaki (2012) (conducted on the Berea sandstone core) and the field trial done by BP at the Endicott field (sandstone reservoir). On the other hand, we believe that during the modified salinity waterflooding in carbonate reservoirs, calcite is dissolved and it liberates the adsorbed oil from the surface; hence, fresh surface with the wettability towards more water-wet is created. Therefore, we model wettability to be dynamically altered as a function of calcite dissolution in UTCOMP-IPhreeqc. We then apply our integrated simulator to model not only the oil recovery but also the entire produced ion histories of a recently published coreflood by Chandrasekhar and Mohanty (2013) on a carbonate core. We also couple IPhreeqc with UTCHEM, an in-house research chemical flooding reservoir simulator developed at The University of Texas at Austin, for a mechanistic integrated simulator to model alkaline/surfactant/polymer (ASP) floods. UTCHEM has a comprehensive three phase (water, oil, microemulsion) flash calculation package for the mixture of surfactant and soap as a function of salinity, temperature, and co-solvent concentration. Similar to UTCOMP-IPhreeqc, we parallelize the geochemical module of UTCHEM-IPhreeqc. Finally, we show how apply the integrated tool, UTCHEM-IPhreeqc, to match three different reaction-related chemical flooding processes: ASP flooding in an acidic active crude oil, ASP flooding in a non-acidic crude oil, and alkaline/co-solvent/polymer (ACP) flooding.

The low salinity water injection technique (LSWI) has become one of the important research topics in the oil industry because of its possible advantages for improving oil recovery. Several mechanisms describing the LSWI process have been suggested in the literature; however, there is no consensus on a single main mechanism for the low salinity effect on oil recovery. As a result of the latter, there are few models for LSWI and especially for carbonates due to their heterogeneity and complexity. In this research, we proposed a systematic approach for modeling the LSWI effect on oil recovery from carbonates by proposing six different methods for history matching and three different LSWI models for the UTCHEM simulator, empirical, fundamental, and mechanistic LSWI models. The empirical LSWI model uses contact angle measurements and injected water salinity. The fundamental LSWI model captures the effect of LSWI through the trapping number. In the mechanistic LSWI model, we include the effect of different geochemical reactions through Gibbs free energy. Moreover, field-scale predictions of LSWI were performed and followed by a sensitivity analysis for the most influential design parameters using design of experiment (DoE). The LSWI technique was also optimized using the response surface methodology (RSM) where a response surface was built. Also, we moved a step further by investigating the combined effect of injecting low salinity water and carbon dioxide on oil recovery from carbonates through modeling of the process and numerical simulations using the UTCOMP simulator. The analysis showed that CO2 is the main controller of the residual oil saturation whereas the low salinity water boosts the oil production rate by increasing the oil relative permeability through wettability alteration towards a more water-wet state. In addition, geochemical modeling of LSWI only and the combined effect of LSWI and CO2 were performed using both UTCHEM and PHREEQC upon which the geochemical model in UTCHEM was modified and validated against PHREEQC. Based on the geochemical interpretation of the LSWI technique, we believe that wettability alteration is the main contributor to the LSWI effect on oil recovery from carbonates by anhydrite dissolution and surface charge change through pH exceeding the point of zero charge.

The mechanics of fracture and fatigue have produced a huge body of research work in relation to applications to metal materials and structures. However, a variety of non-metallic materials (e.g., concrete and cementitious composites, rocks, glass, ceramics, bituminous mixtures, composites, polymers, rubber and soft matter, bones and biological materials, and advanced and multifunctional materials) have received relatively less attention, despite their attractiveness for a large spectrum of applications related to the components and structures of diverse engineering branches, applied sciences and architecture, and to the load-carrying systems of biological organisms. This book covers the broad topic of structural integrity of non-metallic materials, considering the modelling, assessment, and reliability of structural elements of any scale. Original contributions from engineers, mechanical materials scientists, computer scientists, physicists, chemists, and mathematicians are presented, applying both experimental and theoretical approaches.

It is widely accepted that oil recovery during waterflooding can be improved by modifying the composition of the injected brine in a process known as low salinity/ engineered waterflooding. In recent years, several studies, ranging from laboratory corefloods to field trials, have shown the positive effect of engineered waterflooding on oil recovery; however, a few studies have shown no benefit gain from this approach. The inconsistency in responses is because the main mechanism underpinning this recovery method is not fully understood. Several mechanisms have been proposed as the dominant mechanism of engineered waterflooding. Although wettability alteration is believed to be the principal mechanism of engineered waterflooding, the main mechanism leading to wettability alteration is not yet agreed upon. In this research, we follow a systematic approach to develop a model that can be used to evaluate the efficiency of the engineered waterflooding process at different length-scales. We hypothesize that wettability alteration, as a consequence of changes in surface charges at oil/brine and brine/rock interfaces, is the underlying mechanism of engineered waterflooding. We perform surface complexation modeling and contact angle calculation to explain the mechanism of the process at small length-scales. We then implement the developed model into UTCOMP-IPhreeqc, a compositional reactive-transport simulator, developed at The University of Texas at Austin. We conduct coreflood history-matching on carbonate and sandstone cores to validate the model and interpret the underlying mechanism of the process. Finally, we employ the model to assess the applicability and efficiency of engineered waterflooding in field-scale scenarios. Most of the experimental and modeling studies performed in the area of engineered waterflooding neglect the effect of CO2 dissolution in the aqueous phase. However, the presence of CO2 in the reservoir can alter the geochemical equilibrium state and the performance of engineered waterflooding. To address this problem, we implement four-phase flash equilibrium calculations into UTCOMP-IPhreeqc. We use the developed model to investigate the effect of CO2 dissolution in the aqueous phase on the performance of engineered waterflooding. To reduce the computational time of reactive-transport simulations, we implement the geochemical modules of UTCOMP-IPhreeqc into a parallel reservoir simulator framework. Moreover, we develop a new speedup scheme which can reduce the computational time of geochemical equilibrium calculations up to 80%. Carbonated Water Injection (CWI) is another promising enhanced oil recovery technique that takes advantage of both CO2 and water flooding processes. In this method, CO2 is added to the injected brine and transported in the reservoir by flood water. While there are several laboratory experiments reported on this process, simulation studies in this area are scarce. In this research, we use UTCOMP-IPhreeqc to understand the mechanisms of the CWI process and investigate the effect of carbonated brine injection on petrophysical properties of the reservoir. We verify the developed model against an analytical model and apply our simulation approach to match carbonate and sandstone corefloods. Finally, we design a synthetic field-scale case study and evaluate the efficiency of CWI on oil recovery. Alkaline-Surfactant-Polymer (ASP) flooding is another EOR method that usually yields significant incremental oil recovery compared to waterflooding. One major concern for high pH ASP flooding is the possibility of inorganic scale formation near the wellbore and in the production facility. To address this problem, we perform batch and 1D single phase geochemical calculations to identify the possibility and extent of scale formation during ASP flooding. Moreover, we use UTCHEM-IPhreeqc, a coupled chemical flooding simulator and geochemical tool, and design a synthetic field-scale model to study scale formation due to ASP injection in a carbonate reservoir

“Blue is the new green.” This is an all-new revised edition of a modern classic on one of the most important subjects in engineering: Water. Featuring a total revision of the initial volume, this is the most comprehensive and up-to-date coverage of the process of desalination in industrial and municipal applications, a technology that is becoming increasingly more important as more and more companies choose to “go green.” This book covers all of the processes and equipment necessary to design, operate, and troubleshoot desalination systems, from the fundamental principles of desalination technology and membranes to the much more advanced engineering principles necessary for designing a desalination system. Earlier chapters cover the basic principles, the economics of desalination, basic terms and definitions, and essential equipment. The book then goes into the thermal processes involved in desalination, such as various methods of evaporation, distillation, recompression, and multistage flash. Following that is an exhaustive discussion of the membrane processes involved in desalination, such as reverse osmosis, forward osmosis, and electrodialysis. Finally, the book concludes with a chapter on the future of these technologies and their place in industry and how they can be of use to society. This book is a must-have for anyone working in water, for engineers, technicians, scientists working in research and development, and operators. It is also useful as a textbook for graduate classes studying industrial water applications.
