Abstract (sommario):
Integrated membrane system is one of the current leading techniques repoprted for oil-water separation in current years. These combination of different filtration membranes offered the improved separation efficiency of the integrated membrane system during oil-water separation. Although the integrated membrane system is hilighted as the promissing method for oil-water separtion in various industries, the poor membrane wettability was reported which hampers the performance of the membrane. The poor estimation of the membrane wettability in the integrated membrane feed stream leads to the pores blockages, decline oil-water efficiecy and pooor oil/water rejection ratio. The integrated membrane feed stream is prone to membrane fouling during oil-water sepration due to poor membrane wattability. To improve the performance of the integrated membrane system this review covers the membrane wettability during oil-water separation, the techniques used to improve the membrane wettability during oil-water separtion and mathematical models developed to enhance the fundermental understanding of the membrane wettability during oil-water separation. Even though the integrated membrane feed stream has been reported to be having the limitation due to the poor membrane wettabillity, the integrated membrane system is still considered to be the better technique which separates the oil-water emulsions compared to the traditional methods.

Abstract (sommario):
The purpose of this work was to study the wettability of single-walled carbon nanotube (SWCNTs) and molten 96.5Sn-3.0Ag-0.5Cu (SAC305) lead-free solder alloy. The SWCNTs was coated with silver (Ag) by using an electroless plating method in order to enhance its wettability. The wetting behavior of molten SAC305 alloy on three different substrates, alumina, un-coated SWCNTs and Ag-coated SWCNTs was investigated by employing a modified sessile drop technique. The wetting angle between the molten SAC305 and the three substrates was measured at temperature range of 250-550 °C. The average wetting angles between the molten SAC305 and the alumina, the un-coated SWCNTs and the Ag-coated SWCNTs substrates were 130.7±1.3°, 128.4±4.2° and 120.1±3.5°, respectively. The wettabilty of the SWCNTs was improved by coating it with silver. The wetting angle of the Ag-coated SWCNTs was decreased approx. 9° compared to that of the un-coated. Increasing temperature has slightly affected on the wettability of SWCNTs and the molten SAC305.

Abstract (sommario):
This study aims to study the influence of surface topography on the photocatalytic reaction of TiO2 film surfaces. In this work, a textured TiO2 film surface was fabricated by anodic oxidizing a titanium plate with micro grooves, and its wettabilty was evaluated. Micro grooves were machined on a 3-axis NC control precision machine tool using a single point diamond cutter with a tip radius of several hundred nanometers. Anodic oxidation experiments were conducted by using the self-developed equipment with diluted acetic acid as the electrolyte. It was found that the wettability of the TiO2 film surface textured by microcutting was superior to that textured by polishing under the irradiation environment of ultraviolet rays. The wettability of photocatalytic film surfaces could be improved by increasing the surface area.

Abstract (sommario):
Wettability is a crucial petrophysical parameter for determining accurate production rates in oil and gas reservoirs. However, industry standard wettability measurements (Amott Test and USBM) are expensive and time consuming. It is known that NMR response varies as a function of wettability change in rock core plug samples. This information was used to develop an NMR wettability index (NWI) based on T2 distributions. This NWI is capable of measuring changes in wettability as a function of oil/water saturations unlike traditional methods which are based on measurements at Swi and Sor only. In addition, these oil/water saturations are determined without the aid of any special oil or brine, such as D2O. This allows the NMR method to nondestructively monitor changes in wettability in real time (i.e. during a flooding experiment or an aging procedure). In this work, we have coupled this T2-based NWI to spatially resolved T2 NMR measurements to monitor changes in wettability and saturation along rock core plugs. In order to derive an NMR wettability index, NMR T2 spectra of 100% brine saturated, 100% oil saturated, bulk oil and bulk brine are needed. These spectra are then mixed to give a predicted T2 spectrum which is compared (via a least squares fit) to a T2 spectrum recorded from a sample partially saturated with both water and oil and whose wettability is to be determined. For initial testing, three sandstone samples were employed along with 2% KCl brine and dodecane. To achieve sample states of mixed wettability, 100% brine saturated samples had dodecane pushed into them via centrifugation. Centrifugation at different speeds resulted in samples of varying bulk and spatial wettabilities from which NWI parameters and oil/water saturations were determined. The bulk wettabilities were compared to measurements done using the standard Amott test and oil/water saturations were confirmed by repeating experiments using NMR invisible D2O.

Abstract (sommario):
As the world of semiconductor is moving towards smaller and high-end applications, the quality of the bonding adhesion for wire bonding is very critical. Although aluminium has been the metallization of choice in integrated circuits, it can be easily oxidized during high temperature and pressure. On the other hand, Platinum metallization layer has high thermal coefficient resistance and inert to oxygen. This paper reports the correlation between surface roughness and the wettability in the form of contact angle for Platinum deposited wafer etched using Inductively Couple Plasma-Reactive Ion Etching (ICP-RIE). Surface roughness was measured using AFM while contact angle was obtained via droplet test. The results clearly suggested that both surface roughness and wettabily, calculated by its contact angle value has the same trend. Surface roughness is directly proportional to the contact angle. This indicates that surface roughness have great influence on the surface wettability. Therefore, the adhesion for wire bonding process on platinum metallization which can be used in high end applications can be controlled by its surface roughness and wettability.

Abstract (sommario):
Contact of surfactant solution onto rock surface has an important impact on the wettability alteration of the rock. This phenomenon has widely received attention of researchers on the field of EOR (enhanced oil recovery), at which surfactant solution basically has been used as the main injection fluid. However, there has not yet come up with conclusive findings, which is due to the unique characteristics of surfactant used at the oil fields. Therefore, every surfactant needs a particular laboratory evaluation before injected into a reservoir. We have evaluated surfactant-induced wettability alteration by means of contact angle measurement. Three kinds of surfactant have been used in this experiment, namely: TFSA (thin film spreading agent), IFT-R (interfacial tension reduction), and Well Stimulator type of surfactants. Two kinds of rocks namely LS (limestone) and SL (sandy limestone) have also been prepared. Both rocks are originally oil wet. TFSA-LS interaction tend to decrease the oil preferences with time, the contact angle increased 30 degrees after 8 weeks. Whereas TFSA-SL experienced only a little change of contact angle. Contact IFT-R and LS has changed significantly the contact angle to around 51degrees indicating less oil preference. Whereas, IFT-R and SL only changed a bit to less oil wet. The stimulator type of surfactant obviously lessen the oil wet tendency for the both rocks, the contact angles increase from initially around 15 to 35 degrees. In this experiment we found out that all the three surfactants generally tend to change the wettabillity to less oil wet.

Abstract (sommario):
We will investigate the effect of temperature on wettability. First, we will list and summarize the different schools of thoughts from previous literature describing wettability changes for sandstone and carbonate reservoirs at elevated temperature. Next, we will describe the properties that affect wettability: how they alter wettability and how they are affected by temperature. After that, we will present indications of wettability changes and current wettability measurement techniques. Following this, case studies describing how wettability change influences reservoir characteristics and field performance during thermal recovery processes will be discussed. The thermal recovery methods included in the case studies were steam flooding, cyclic steam injection, hot water flooding, and in situ combustion. The main and very important take away from this study is that temperature induced wettability change is determined by many possible mechanisms combined together and not by just one or two phenomena occurring simultaneously. Finally, we will propose a reasonable scheme for wettability alteration during dry forward combustion, which needs further investigation.

Abstract (sommario):
Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. In addition, wood/liquid interaction such as water wettability on wood plays an important role in design and characteristics of many processes and phenomena such as adhesion, coating, waterproofing, wood chemical modification, and weathering. This thesis focuses on enhancing the understanding of wetting of wood, with emphasis on modified wood. The influence of surface chemical composition of wood and its microstructural characteristics on wetting and swelling properties has also been studied. A multicycle Wilhelmy plate technique has been developed to evaluate wetting properties of porous materials, such as wood, in which the samples were subjected to repeated immersions and withdrawals in a swelling liquid (water) and in a non-swelling liquid (octane). This method was utilized to dynamically investigate contact angle, sorption and swelling properties, as well as dimensional stability of unmodified, chemically and surface modified wood samples. Scots pine sapwood and heartwood samples were utilized to establish the principles of the technique. Acetylated and furfurylated wood samples with different level of modification were thereafter examined utilizing the developed technique for wetting measurements. A perimeter model based on a linear combination of the measured force and final change in sample perimeter was suggested to evaluate the dynamic dimensional stability of wood veneers. The feasibility of this method for studying dynamic wettability was investigated by measuring the changes of advancing and receding contact angles over repeated cycles on surface modified wood samples, created by combining liquid flame spray and plasma polymerisation methods. X-ray photoelectron spectroscopy (XPS) and X-ray computed tomography (XCT) were employed to study the surface chemical composition and microstructural properties of the samples, respectively. Three different kinetic regimes were observed in the wetting measurements: i) fast wetting and spreading of the liquid on the wood surface, ii) void filling and wicking and iii) swelling, which was the slowest of the three. The multicycle Wilhelmy plate method was found to be suitable for studying liquid penetration, sorption, and dimensional stability of swelling materials. The results demonstrate that the wetting properties of wood are highly affected by surface chemistry and microstructure. It was shown that using both swelling and non-swelling liquids in wetting measurements allow to distinguish between capillary liquid uptake and swelling. Based on this, for chemically modified samples, it was demonstrated that acetylation mostly reduces swelling, while furfurylation reduces both swelling and capillary uptake. This is in line with the microstructural study with X-ray computed tomography where a significant change in the porosity was found as a result of furfurylation, conversely acetylation left the total porosity values unchanged. Wetting results for hydrophobised wood samples demonstrate that the multi-scale roughness obtained by combination of nanoparticle coating and plasma polymerization increased both the hydrophobicity and the forced wetting durability compared to the micro-scale roughness found on wood modified with plasma polymerisation alone.

Abstract (sommario):
This project aims at the fabrication of a rough polydimethylsiloxane(PDMS) surface with patterned smooth areas. The idea is that such a surface will allow for water capturing on the smooth areas of the surface. The applications for this kind of surface are many, but especially the prospects of a surface able to trap droplets of cells in suspension by simply dipping the surface into the suspension is intriguing.From a previous project[1], and another student’s master’s thesis[2], the use of an etched copper surface seemed promising for the fabrication of a rough mold. This was abandoned after sandpaper turned out to be an even better mold, giving superhydrophobic PDMS(162, 33 ± 1, 40degrees).The negative photoresist SU-8 5 was used to pattern the sandpaper with small, circular features on the P1000 sandpaper(400μm and 1mm in diameter). The PDMS replica from this mold was a rough surface with smooth wells. This was not able to capture water droplets effectively, partly because air bubbles were trapped in the wells during the immersion in water. To avoid this, another mold was procured by the silanization of the previously made PDMS surface. The PDMS replica of the silanized PDMS had smooth pillars instead of wells, and did not succeed in trapping water droplets either. In fact, the smooth wells seemed to better at capturing the water.This project has succeeded in producing high enough roughness on PDMS to alter the contact angle with water by ∼ 61 degrees to a contact angle exceeding the lower limit for superhydrophobic surfaces by ∼ 12 degrees. The use of a sandpaper mold has proven to is simple, inexpensive and effective at producing PDMS with high contact angles.

Abstract (sommario):
Nuclear Magnetic Relaxation Dispersion (NMRD) is strongly sensitive to the microscopic wettability of oil and brine bearing carbonate rocks. Exploring a very large range of low frequency enables isolating the typical NMRD dispersion features, 1/T1Surf, associated to the different processes of molecular surface dynamics. This allows a separation of the surface and bulk microdynamics of oil and water even for a biphasic saturation of petroleum rocks. Several surface dynamical parameters were determined and related to the concept of microscopic wettability of oil and water in porous media.

Abstract (sommario):
In this study, a surface with patterned wettability by means of surface structuring, rather than through modifying the surface chemistry, was developed. The device presented in this thesis was inspired by the Namib Desert Bettle, which collects water from the fog by having hydrophilic spots surrounded by hydrophobic wax-coated regions on its back. Besides water collection, controlling the wetting behaviour locally on the surface may find applications within droplet-based microfluidics, or fabrication of DNA, protein or cell microarrays. Spatial wetting contrast was achieved through replica moulding of the elastomer polydimethylsiloxane (PDMS), using a copper and/or the epoxy-based SU-8 photoresist surface as a template. Different types of surface roughness was produced and characterized on polycrystalline copper, through etching, oxidation, electrodeposition, or a combination. Regions with no surface roughness was patterned on the template moulds through conventional UV-photolithography processing of SU-8. The PDMS replicas were then tested for the ability to capture water droplets selectively on the patterned spots. Through characterization of the surface roughness by atomic force microscopy (AFM) and scanning electron microscopy (SEM), copper plates etched with a solution of CuCl2 and HCl produced the highest amount of surface roughness, with longer etching times leading to increased surface roughness. To characterize the hydrophobicity, the contact angle was measured for droplets deposited on the rough PDMS surfaces. Through surface structuring, the contact angle was increased from 101.8 ± 3.6◦ for a flat surface, to 154.7 ± 5.3◦ for the PDMS surface with the highest roughness. The polarity of surface roughness was also found to play an important role in the wetting behaviour, with a higher number of peaks than valleys being preferable. The fabricated PDMS surfaces showed spatial wetting contrast, as demonstrated in the cover photo. The device needs further optimization in terms of increasing the hydrophobicity of the rough regions, as well as changing the pattern geometries. However, the discoveries made in this study may be useful for further development and integration with droplet-moving mechanisms, for future lab-on-a-chip applications within medical diagnostics or chemical analysis.

Abstract (sommario):
The surface charge of carbonate minerals, which is also expressed in terms of the zeta potential, plays a key control on reservoir wettability, and changes in the zeta potential have been invoked to explain wettability alteration and the release of previously trapped oil during controlled salinity waterflooding (CSW). We report a method to characterize the zeta potential of carbonates, based on measurements of streaming potential, which can be used to determine the zeta potential of mineral-brine and oil-brine interfaces within the porous medium. The aim of this project was to determine the effect of total salinity, potential determining ion (PDI) contribution, and wetting state on the zeta potential of limestone. In the first part, we use the streaming potential method to obtain measurements of zeta potential on intact core samples at typical reservoir brine salinity and composition. We determine the impact on zeta potential of varying the total salinity, and the concentration of the PDIs calcium, magnesium and sulfate. The impact of each PDI was determined over a wide range of concentrations naturally found in sea water, formation brines, and typical compositions used in CSW. We find that the zeta potential varies identically and linearly with calcium and magnesium concentration expressed as pCa or pMg. The zeta potential also varies linearly with pSO4. The sensitivity of the zeta potential to PDI concentration, and the IEP (iso-electric point) expressed as pCa or pMg, both decrease with increasing NaCl concentration. We report considerably lower values of IEP than most previous studies, and the first observed IEP expressed as pMg. The sensitivity of the zeta potential to PDI concentration is lower when measured using the SPM compared to the EPM, owing to the differing location of the shear plane at which the zeta potential is defined. In the second part, we use the streaming potential method to investigate how the zeta potential changes when an oil phase is introduced in the rock sample. We establish a relationship between wettability and the zeta potential. This is done for samples that were aged in the presence and absence of a brine phase, in order to represent mixed-wet and oil-wet cases. In addition, measurements on non-aged samples were conducted in order to represent the water-wet case. We find that the more oil-wet the system is, the more negative the zeta potential gets with the oil-wet case being the most negatively charged. For the crude oil samples, we find that there is a strong correlation between the Amott Index and the zeta potential. Our findings suggest that the streaming potential method can be used to assess the impact of water chemistry and wetting state on the surface charge of limestone. The results are directly applicable to wettability characterization and understanding of wettability alteration that may take place during CSW.

Cataloged from PDF version of thesis.
Includes bibliographical references (p. 85-90).
This thesis presents the development of the conducting polymer polypyrrole as a viable material for applications requiring switchable wettability. A fabrication procedure that produces robust microstructured polypyrrole (PPy) that quickly and reversibly switches between the superhydrophobic and superhydrophilic states is discussed. The polymer is doped with perfluorooctanesulfonate ions which diffuse in and out of the film upon an electric stimulus, causing a change in the material's surface energy. The effect of changing different deposition parameters on the switchable wettability of the polymer is also investigated. A post-deposition thermal treatment that improves the electrochemical properties of polypyrrole is presented. Finally, a device that allows for the in situ wettability switch of PPy is developed, eliminating the need for polypyrrole to be immersed in an electrolyte in order to switch between wetting states. A wettability gradient created on the surface of PPy using the device is used to demonstrate a possible application requiring induced fluid movement. Electrochemical techniques are used to synthesize and characterize the polymers, and scanning electron microscopy is used to examine the surface morphology of the films.

Abstract (sommario):
Brazilian Pre-Salt carbonate reservoirs have been one of the greatest oil discoveries of the past decade. In fields such as Lula, it is expected to recover between five to eight billion barrels of oil equivalent. To fulfill this, knowledge of reservoir wettability is fundamental, given that it dictates how fluids (water, oil and, gas) are distributed within the porous media, and how the multiphase flow occurs in the pore-network. This information is important in the construction of relative permeability curves which are input for reservoir simulators. Few works have been published regarding initial wettability of Pre-Salt carbonate reservoirs in spite of their great oil recovery potential. In this way, to close the data gap in the literature, this study aimed to investigate parameters that influence initial wettability of pure rocks (calcite and quartz) and analogue rocks (coquinas) that partly represent the Pre-Salt reservoirs. Contact angle experiments were used to study the influence of parameters that are important to rock wettability, such as rock composition, brine salinity, temperature, rock ageing and, presence of carbon dioxide in brine. Initial wettability was analysed at core scale by spontaneous imbibition and core flood experiments, obtaining the Amott index to water. Through these experiments, it was possible to evaluate the performance of di erent brines respective to oil recovery. Furthermore, wettability alteration was investigated in low salinity water injection as a tertiary injection method. Contact angles experiments were also used to analyse wettability alteration in clay-less rocks, focusing on understanding the role of fluid-fluid interactions on low salinity water injection. Respective to initial wettability in pure rocks and rock analogues relevant to the Brazilian Pre-Salt, it was found that at reservoir temperature (60°C) calcite, and quartz were neutral and weakly oil-wet, respectively. Amott index to water indicated that at that temperature, coquina rocks were intermediate-wet (mixed-wet). Presence of carbon dioxide in brine indicated that both calcite and quartz rocks become more water-wet. Regarding the application of wettability to low salinity water injection, the results suggested that wettability alteration is not exclusive of clayey rocks, nor resulting from a change in the ratio of divalent to monovalent cations. They indicated that crude oil composition is crucial for wettability alteration to happen, and it is possible that crude-oil/brine interactions dictate the low salinity effect. In summary, this work generated important data regarding initial wettability of Brazilian Pre-Salt reservoirs which are scarce in the literature. These results also instigate further investigation respective to the effects of carbon dioxide in brine on the initial wettability of rocks considering complex brines (presence of divalent cations and anions) rather than just brines composed of sodium chloride. This work showed that crude-oil/brine interactions is important for the low salinity effect.

Abstract (sommario):
Abstract Thermal sprayed coatings are influenced by the wettabillity of the molten particles to substrates. The contact angles of several molten metal droplets are measured in air and vacuum. The flattening ratio is evaluated by taking into account of wettability. Comparing with the experimental data of the freefall droplet, it was concluded that the wettability to the roughened substrates influenced on the flattening characteristics.

Abstract (sommario):
Surface wettability of materials is important in heat transfer and thermal processes at micro-scale. This paper presents the manipulation of metal surface wettability by nanofluid boiling nanoparticle deposition. As confirmed by microscopy, particles can be deposited on metal surfaces by boiling in nanoparticle suspension, which significantly enhanced the surface wettabiliy relative to that of its original condition. The change in wettability is coupled to boiling conditions, such as nanoparticle concentration, heat flux, boiling duration, substrate roughness and so on. It has been observed that the higher the concentration of nanoparticles in the liquid during the boiling deposition process, the more pronounced the impact on wetting. Hence, surface wettability can be manipulated by controlling the nanoparticle concentration during the nanofluid boiling nanoparticle deposition (NBND) process. Such method can potentially be applied to enhance the heat transfer performance in thermal devices.

Abstract (sommario):
The superhydrophobicity of the microchannels are dependent not only upon the surface energy of the wall but also closely related to the micro- and/or nano-structures on their surfaces. Recent experiments have found that superhrydrophobic surfaces can be achieved by pattering roughness on hydrophobic surfaces. In this paper, the wettability of droplet on microchannel with different wettability and surface micro-structures is numerically studied by using lattice Boltzmann method (LBM). In particular, the effects of different kinds of surface micro-structures on the superhydrophobicity are analyzed. The simulation results show that the surface micro-structures have a significant influence on the wettabiltiy on the solid surfaces. Also, the results have manifested that LBM has a good application prospect in the study of wettability in micro- or nano-channels.

Abstract (sommario):
The initial wetting of a reservoir sets a limit for the EOR potential during water-based recovery operations and “Smart Water” injection. For this reason, an improved understanding of the factors influencing the wetting can help to control and better forecast oil production during water-based floods. To preserve and reproduce the original reservoir wettability is a challenging task and wrong cleaning and core restoration procedures can lead to incorrect wettability estimations and thus induce serious errors when evaluating the initial wettability of a reservoir system or its EOR potential by water-based methods. Thereby, there is a need to improve the chemical knowledge on interactions among the rock, brine and fluids present in reservoir systems. This will help to understanding the influence of the parameters affecting wettability during cleaning and core restoration processes. Understanding which are the main parameters influencing oil recovery processes is of great relevance. The objective of this document is to provide suggestions for added-value experiments, complementing and challenging the standard RCA and SCAL procedures, prior to performing experimental research in which wettability and wettability alteration processes are important. Lessons learned will be highlighted and new ideas to optimize core restoration protocols to preserve and closely reproduce wettability are put forward. These recommended practices target core restoration procedures after the core material has been received in the laboratory. The target audience for this document is engineers and scientists with an interest in core preparation for wettability studies.
