▼ The purpose of hydraulic fracturing in low permeability shales is to maximize surface contact area with the reservoir and create conductive flow paths for the hydrocarbons to be economically produced through. Fracture conductivity is defined as the product of fracture permeability (kf) and the width of the fracture aperture (wf). This parameter is vital as it limits the capacity of the flow path between the stimulated reservoir rock and the wellbore, for a given drawdown pressure. The resulting fracture conductivity is dependent on a plethora of rock and proppant properties. Realistic prediction of conductivity and further understanding of its relationship with rock properties would prove incredibly valuable, especially in new and developing shale plays where there is a steep initial learning curve in economic production. In this study, multiple linear regression is applied to a large database of shale conductivity experiments and a robust correlation for predicting conductivity is presented. In addition, the properties of Young’s modulus, Poisson’s ratio, compressive strength, and Brinell hardness are isolated and their effects on fracture conductivity are analyzed. The shale plays included in the correlations are the Barnett, Fayetteville, Marcellus, and Eagle Ford shales. Brinell hardness and compressive strength were found to be highly correlated with conductivity decline as closure stress increases. Young’s modulus was also found to be a highly significant predictor of fracture conductivity in shales. A higher modulus correlated to increased conductivity at each closure stress. It was also concluded that closure stress and proppant loading conditions have a much greater influence on fracture conductivity when compared to rock mechanical properties and fracture surface characteristics. The final correlation model presented can be used to estimate fracture conductivity in various shale plays. It is important to keep in mind the distributions of the input data into the model, as well as the experimental conditions under which the conductivity was measured when applying this correlation for prediction purposes.

▼ Ultra-deepwater reservoirs are important non-conventional reservoirs that hold the potential to produce billions of barrels of hydrocarbons but present major challenges. Hydraulic fracturing or frac-packing high permeability reservoirs is different from the conventional hydraulic fracturing technology used in low permeability formations. While the main purpose of the conventional technique is to create a long, highly conductive path, frac-packing on the other hand is used predominantly to get past near wellbore formation damage, control sand production and reduce near wellbore pressure drop. Ultra-deepwater reservoirs are usually high temperature and high pressure with high permeabilities. Frac-packing these types of wells requires short fractures packed with high proppant concentrations. Understanding the behavior of the fracture fluid and proppant is critical to pump such a job successfully and to ensure long term productivity from the fracture. A series of laboratory experiments have been conducted to research the different problems resulting from high temperature and pressure which negatively affect conductivity. Unlike conventional long-term conductivity measurements, we placed the proppant into the fracture and pumped fracture fluid through it and then measured conductivity by pumping oil to represent true reservoir conditions. Proppant performance and fracture fluids clean-up during production were examined. High strength proppant is ideal for deep fracture stimulations and in this study different proppant loadings at different stresses were tested to measure the impact of crushing and embedment on conductivity. The preliminary test results indicated that oil at reservoir conditions does improve clean-up of fracture fluid left back in the proppant pack. Increasing the proppant concentration in the fracture showed higher conductivity values even at high closure stress. The increase in effective closure stress with high temperature yielded significant loss in conductivity values as compared to those obtained from industry tests.

▼ To effectively produce from resource shale, a stimulation method is required. Typically, hydraulic fracturing is utilized for stimulation. Hydraulic fracturing methods range in size, cost, and effectiveness. Once a hydraulic fracture network has been generated, the fractures must be propped open using proppant to allow flow through the fractures. Sand is currently the most commonly used proppant in fracture treatments. Large quantities of sand are required to effectively prop the generated and natural fractures. Sand can be a costly expense in the completion stage of a well. With low oil and gas prices, cutting costs, but not jeopardizing the success of the well is critical. The goal of this study is to find a cheap and abundant material which can act as a sand substitute to provide equal or superior fracture conductivity to that of sand proppant, and serve as an adequate proppant material. Glass, taconite tailings, coal, and various proppant mixtures’ geometry, conductivity, and strength were all evaluated and compared to conventional sand proppants currently being used in industry to evaluate the novel proppant’s potential to serve as a sand substitute in hydraulic fracturing treatments. The proppant’s geometry was evaluated qualitatively under a microscope. The most favorable proppant geometry was seen in sand proppant followed by taconite, and the least favorable particle geometry was observed in the glass proppant. Fracture conductivity is an effective means of measuring a fracture treatment’s effectiveness. For that reason, the API RP 61 procedure was followed using the modified API cell available in the Texas A&M University Fracture Conductivity Laboratory to evaluate the conductivity of the various proppant packs. API RP 61 is a well-established procedure set forth by the American Petroleum Institute for measuring conductivity of proppant packs. For a given proppant size, sand had the largest conductivity, followed by taconite, then glass, and finally coal which did not result in any measurable conductivity. Proppant strength was measured by evaluating proppant crushing. Each conductivity test was conducted at the same six closure stresses starting at 1,000 psi and ending at a maximum closure stress of 6,000 psi. Before the proppant conductivity was tested, a sieve test was conducted to determine the particle distribution of each proppant type and size. Upon conclusion of each conductivity test, after the proppant pack had been exposed to 6,000 psi closure stress, the proppant was sieve tested once again. The particle distributions of the crushed and uncrushed samples were compared side by side to determine how severely the proppant had crushed. For a given proppant size, the glass proppant had the most severe crushing followed by the taconite and sand proppants. The proppant geometry and strength evaluations were used to support the large variation in conductivity results observed in this study. A dimensionless conductivity evaluation was conducted to determine the potential for each proppant to… Advisors/Committee Members: Hill, Daniel A (advisor), Zhu, Ding (advisor), Sun, Yuefeng (committee member).

▼ The favorable conductive properties of carbon nanotubes (CNTs) offer opportunities for constructing CNT-based nanocomposites with improved thermal conduction for a range of potential applications. Such lightweight composite materials are expected to have thermal properties that depend on their CNT volume fraction and operating temperature. The construction of CNT-based nanocomposites is challenged by the available processing methods for CNTs that are compatible with the construction of multi-laminated composite structures. The overall goal of this effort is to develop enhanced thermal properties in carbon nanotube-polymer composites that can replace traditional aerospace metallic materials to reduce the weight in space structures. The key innovation of this dissertation is in dispersing the carbon nanotubes onto a prepreg composite structure that sustains thermal storage and increase the thermal transport to support scientific instrumentation to more effectively radiate heat from a composite structure while increasing the thermal properties. The employed structures consisted of individual plies of IM7 prepreg composite with an embedded 8552 epoxy that were each coated with a CNT layer and then combined into the final composite structure using a vacuum-based hand layup technique for curing the 8552 epoxy. The composites were investigated by Raman spectroscopy, thermogravimetric analysis, thermal diffusivity, and differential scanning calorimetry. With varying the concentration of SWCNT up to 30 wt% to the IM7 prepreg composite, its heat capacity sustained over the tested temperature range and its through-thickness thermal diffusivity increased by 30% vs. the virgin composite material. By modeling, such additions of randomly oriented SWCNTs are suggested to increase the in-plane thermal conductivity by 120 to 150% over the temperature range of 120 to 470 K and by 30% in the through-thickness direction. A possible explanation of these improvements in the thermal conductivities are the reductions of the interfacial resistances between the SWCNTs, the 8552 epoxy, and the IM7 composite. The developed methods provide the opportunity for enhancing the thermal properties of a composite through the use of CNTs as additives. Such improvements would be particularly useful in aerospace applications for solar arrays, fairings, and thermal radiators.

▼ The aim of this study was to develop an understanding of the Eagle Ford shale unpropped and propped fracture conductivity. Samples were collected at Antonio Creek and Lozier Canyon. Both outcrops are several hundred feet thick and extend for a few thousand feet laterally. At these locations five different geological facies (A, B, C, D and E), each with distinct lithological characteristics and geochemical properties that can be correlated to the Eagle Ford shale in the subsurface are accessible. The mineralogy of the collected samples was determined via x-ray diffraction which corroborates the relationship of the samples to the outcrops and hence to the Eagle Ford shale in the subsurface. After collected, the samples were cut into modify API conductivity cell dimensions. The fracture conductivity at different closure stresses was determined based on laboratory measurements of flow rate and pressure drops along the fracture. The fluid used in this work was nitrogen. The proppant concentration used is representative of what is commonly used in hydraulic fracturing treatments in the Eagle Ford shale. The heterogeneity of the Eagle Ford shale is addressed by obtaining conductivity samples in two different directions with respect to the bedding plane for the five geological facies. Three directions were obtained for facies B. Fracture area and fracture roughness (surface attributes) were calculated from the data taken by a surface profilometer. The mechanical properties, namely Young’s modulus, Poisson’s ratio and Brinell hardness, were experimentally determined from core plugs acquired from the same rocks where the conductivity samples were obtained. The effect that the surfaces attributes, mechanical properties and geological facies (mineralogy) have on conductivity was analyzed and the major findings of this work are the following. From this study, we found that fracture orientation has an impact on the fracture conductivity. It was also found that the geological characteristics (mineralogy) and mechanical properties (Poisson’s Ratio) impact the fracture conductivity. The geological facies (lithology) impact the fracture conductivity in Eagle Ford shale. Facies A, B and C exhibit a good relationship between fracture conductivity and surface attributes (fracture roughness and area). This relationship is not present in facies D and E. This work provides a foundation for future studies (damage mechanism) of the Eagle Ford shale fracture conductivity and gives an insight into the relationship of fracture conductivity and geological facies.

▼ Low-permeability gas wells often produce less than predicted after a fracture treatment. One of the reasons for this is that fracture lengths calculated after stimulation are often less than designed lengths. While actual fracture lengths may be shorter due to fracture growth out of zone, improper proppant settling, or proppant flowback, short calculated fracture lengths can also result from incorrect analysis techniques. It is known that fracturing fluid that remains in the fracture and formation after a hydraulic fracture treatment can decrease the productivity of a gas well by reducing the relative permeability to gas in the region invaded by this fluid. However, the relationships between fracture fluid cleanup, effective fracture length, and well productivity are not fully understood. In this work I used reservoir simulation to determine the relationship between fracture conductivity, fracture fluid production, effective fracture length, and well productivity. I simulated water saturation and pressure profiles around a propped fracture, tracked gas production along the length of the propped fracture, and quantified the effective fracture length (i.e., the fracture length under single-phase flow conditions that gives similar performance as for multiphase flow conditions), the "cleanup" fracture length (i.e., the fracture length corresponding to 90% cumulative gas flow rate into the fracture), and the "apparent" fracture length (i.e., the fracture length where the ratio of multiphase to single-phase gas entry rate profiles is unity). This study shows that the proppant pack is generally cleaned up and the cleanup lengths are close to designed lengths in relatively short times. Although gas is entering along entire fracture, fracturing fluid remains in the formation near the fracture. The water saturation distribution affects the gas entry rate profile, which determines the effective fracture length. Subtle changes in the gas rate entry profile can result in significant changes in effective fracture length. The results I derived from this work are consistent with prior work, namely that greater fracture conductivity results in more effective well cleanup and longer effective fracture lengths versus time. This study provides better explanation of mechanisms that affect fracturing fluid cleanup, effective fracture length, and well productivity than previous work.

Research Doctorate - Doctor of Philosophy (PhD)

This study investigated the heat transfer behaviour of nanofluids with focus on a magnetite nanofluid as an alternative for the next generation of cooling applications. The very first aim of this study was to shed light on conflicting data reported in the literature about the thermal conductivity of conventional nanofluids (non-magnetic). For this purpose, the thermal conductivity of different nanofluid samples were measured under different conditions (namely particle volume fractions, temperature and pH) and results were compared with theoretical prediction of mixture theory. Shortcomings of different hypotheses were examined, analysed and explained. All of the experimental data were within the ±10% boundary of theoretical mixture theory (i.e. Maxwell model). It was shown that higher thermal conductivity in the conventional nanofluids can be achieved by controlling the aggregation size (i.e. pH value). To test this hypothesis, artificial aggregates were generated by applying an external magnetic field to the magnetite nanofluid. Thermal conductivity enhancement by up to 160% was observed for 0.86 vol% magnetite nanofluids (Fe3O4-water), subjected to the magnetic field intensity of 32 mT parallel to the temperature gradient. On the other hand, the thermal conductivity of magnetite nanofluid is almost constant under the applied magnetic field perpendicular to the temperature gradient. Convective heat transfer coefficient of magnetite nanofluid under laminar flow condition was also considered in the absence and presence of an external magnetic field. Heat transfer in magnetite nanofluids with and without magnetic field has been performed previously. However, the extent of the experiments and analysis is the main goal which has been achieved through this study. It has been shown that the experimental data in the absence of an external magnetic field follows the prediction of standard correlation for laminar flow heat transfer (Shah equation) using the thermophysical properties of nanofluid. Up to 300% enhancement in convective heat transfer enhancement has been observed at Re=745 and the magnetic field gradient of 32.5 mT/mm. Moreover, the effect of magnetic field on pressure drop was insignificant. It is concluded here that aggregation is the main mechanism of heat transfer in nanofluids. The thermal conductivity and convective heat transfer coefficient of magnetite nanofluids can be altered far beyond the prediction of traditional theories by applying an external magnetic field.

▼ Silicon germanium alloys (SiGe) have long been used in thermoelectric modules for deep-space missions to convert radio-isotope heat into electricity. They also hold promise in terrestrial applications such as waste heat recovery. The performance of these materials depends on the dimensionless figure-of-merit ZT (= S2σ T/ κ), where S is the Seebeck coefficient, σ the electrical conductivity, κ the thermal conductivity, and T is the absolute temperature. Since 1960 efforts have been made to improve the ZT of SiGe alloys, with the peak ZT of n-type SiGe reaching 1 at 900 - 950 C. However, the ZT of p-type SiGe has remained low. Current space-flights run on p-type materials with a peak ZT ~ 0.5 and the best reported p-type material has a peak ZT of about 0.65. In recent years, many studies have shown a significant enhancement of ZT in other material systems by utilizing a nanostructuring approach to reduce the thermal conductivity by scattering phonons more effectively than electrons. Here we show, using a low-cost and mass-production ball milling and direct-current induced hot press compaction nanocomposite process, that a 50% improvement in the peak ZT, from 0.65 to 0.95 at 800 - 900C is achieved in p-type nanostructured SiGe bulk alloys. The ZT enhancement mainly comes from a large reduction in the thermal conductivity due to the increased phonon scattering at the grain boundaries and crystal defects formed by lattice distortion, with some contribution from the increased electron power factor at high temperatures. Moreover, nanocomposite approaches have been used to study the thermoelectric properties of other material systems such as bismuth telluride (Bi-Te), bismuth antimony (Bi-Sb), and half-Heusler phases. We observed a significant improvement in peak ZT of nanostructured p- and n-type half-Heusler compounds from 0.5 to 0.8 and 0.8 to 1.0 respectively. The ZT improvement is mainly due to the reduction of thermal conductivity. This nanostructure approach is applicable to many other thermoelectric materials that are useful for automotive, industrial waste heat recovery, space power generation, or solar power conversion applications.

▼ Riparian zones in semi-arid regions often exhibit high rates of evapotranspiration (ET) in spite of low soil moisture content due to vegetation that is able to withdraw water from shallow aquifers. This work better defines the relationship between ET and the saturated zone by comparing the observed water table drawdown to analytically modeled drawdown in fully penetrating wells of an unconfined aquifer in response to daily ET flux. ET at the Boise Hydrogeophysical Research Site or BHRS (a riparian zone in a temperate, semi arid environment) is calculated following the approach of Batra et al. (2006) but uses site (or near site) measurements for air temperature and net radiation while relying on Landsat 5 data for quantification of vegetation. The resulting ET calculations represent a data set consisting of high resolution (30m x 30m) ET flux values obtained from minimal site measurements. Water table levels in the shallow, unconfined aquifer were monitored over the summer and fall of 2009 to record the timing and magnitude of daily fluctuations in four wells with different vegetation densities and distances from the nearby Boise River at the site. ET derived from the radiation-driven model of Batra et al. (2006) compares favorably with groundwater ET contribution rates calculated from well hydrographs (White, 1932), which further supports the finding of negligible water contribution coming from the unsaturated zone in shallow riparian aquifers in semi-arid regions (Shah et al., 2007). Using an analytical solution to ET induced drawdown (Malama & Johnson, 2010) for a semi-infinite (or river bounded) domain, daily drawdown is modeled in response to daily ET flux applied at the water table. Close agreement between observed and modeled drawdown supports the idea that ET can be estimated from well hydrographs in a wellcharacterized aquifer and conversely, if ET behavior is characterized, aquifer parameters like hydraulic conductivity and specific storage can be estimated from well hydrographs.

▼ Electrically conductive polymer composites, i.e. polymers filled with conductive fillers, may display a broad range of electrical properties. A rational design of fillers, filler surface chemistry and filler loading can tune the electrical properties of the composites to meet the requirements of specific applications. In this dissertation, two studies were discussed. In the first study, highly conductive composites with electrical conductivity close to that of pure metals were developed as environmentally-friendly alternatives to tin/lead solder in electronic packaging. Conventional conductive composites with silver fillers have an electrical conductivity 1~2 orders of magnitude lower than that of pure, even at filler loadings as high as 80-90 wt.%. It is found that the low conductivity of the polymer composites mainly results from the thin layer of insulating lubricant on commercial silver flakes. In this work, by modifying the functional groups in polymer backbones, the lubricant layer on silver could be chemically reduced in-situ to generate silver nanoparticles. Furthermore, these nanoparticles could sinter to form metallurgical bonds during the curing of the polymer matrix. This resulted in a significant electrical conductivity enhancement up to 10 times, without sacrificing the processability of the composite or adding extraneous steps. This method was also applied to develop highly flexible/stretchable conductors as building block for flexible/stretchable electronics. In the second study, a moderately conductive carbon/polymer composite was developed for use in sensors to monitor the thermal aging of insulation components in nuclear power plants. During thermal aging, the polymer matrix of this composite shrank while the carbon fillers remained intact, leading to a slight increase in filler loading and a substantial decrease in the resistivity of the sensors. The resistivity change was used to correlate with the aging time and to predict the need for maintenance of the insulation component according to Arrhenius’ equation. This aging sensor realized real-time, non-destructive monitoring capability for the aging of the target insulation component for the first time. Advisors/Committee Members: Wong, C. P.

▼ The notion that an array of free radicals might behave like metallic sodium was first suggested by McCoy and Moore in 1911. While the hypothesis represents an important historical landmark, there are many synthetic challenges associated with designing a conductive radical, such as the high propensity for these materials to dimerize and thus quench the free spin. Considerable advances have been made to overcome spin-pairing, including incorporation of heteroatoms such as sulfur and nitrogen atoms. Over the last 20 years, the Oakley group has used thiazyl radicals as a building block for multifunctional materials. While the early frameworks possessed a high barrier to charge transport, U, trapping the materials in Mott insulating states, the development of resonance-stabilized oxobenzene-bridged bisdithiazolyl radicals has led to a significant decrease in U, and metallic conductivity under mild pressure have also been observed. The focus of this thesis is on the design, synthesis, and characterization of new oxobenzene-bridged radicals, and the effects of pressure on these systems. One particularly interesting system is the prototypal-oxobenzene-bridged radical, in which compression from 0 – 13 GPa afforded two additional phases and a significant increase in conductivity, peaking at 2 S cm-1 at 6 GPa with a concomitant decrease in Eact to zero, consistent with formation of a metallic state. Density functional theory (DFT) calculations were used to probe the electronic structure of these oxobenzene-bridged radicals, and these revealed the multiband electronic structure which is the source of the superior physical properties of these materials compared to previous generations of thiazyl radicals. The intrinsically low U values and diverse structural variety exhibited by these oxobenzene-bridged radicals prompted the study of other substituents at the basal site. Studies on the early monocyclic DTDA systems were explored in pursuit of structure-directing ligands which can alter the solid-state packing to improve the bandwidth W. To this end, a pyridyl moiety was incorporated onto the DTDA framework, in which molecular ribbons laced together laterally by S – N intermolecular contacts was observed. However, these radicals crystallize as diamagnetic dimers, and are insulators. Nevertheless, it was established that nitrogen can be used as a structure directing ligand. Consequently, incorporation of a pyridine-quinone core into the oxobenzene-bridged framework was pursued in hopes of generating a more tightly bound structure with improved bandwidth, W. While the synthesis of the radical was not achieved, a variety of new synthetic procedures and novel species were developed. The last and most recent work involves the incorporation of a π-acceptor (i.e. NO2) at the basal site of the oxobenzene-bridged framework, and the resulting material displays the lowest Ecell (U) = 0.45 V ever observed for a neutral radical. While this is still ongoing work, preliminary results on the synthesis, crystallography, magnetic and…

▼ Soil scientists have been using the same quantification methods for soluble salts for decades. Yet they have long struggled with an effective method for quantifying gypsum content, because current methods are fraught with problems. Saline soil has been historically defined as soil containing salts more soluble than gypsum (e.g., various combinations of Na+, Mg2+, Ca2+, K+, Cl-, SO42-, HCO3- and CO32-) to the extent that soil fertility is severely reduced across a wide array of climates and geological settings. Since salinity is not germane to specific soil characteristics such as texture or parent material, it can be challenging to predict salt concentrations within a profile. Given the success of previous studies using portable x-ray fluorescence (PXRF) as a tool for measuring soil characteristics, the evaluation of soluble salts in soil with PXRF seems timely. Not only does this newer technology offer more accurate, quantifiable data to investigators, it produces results in-situ, in seconds. Recent enhancements to PXRF spectrometers have provided better detection limits especially for lighter elements such as S and Cl, a key component of gypsum and other salts. Thus, this research aimed to test the effectiveness of PXRF as a means of directly quantifying gypsum and salinity in soils. A total of 102 soil samples containing a wide variety of gypsum (~2–95%) and 122 samples with various salt concentrations were subjected to both traditional laboratory analysis (thermogravimetry and electrical conductivity, respectively) and elemental analysis via PXRF. Simple and multiple linear regression were used to establish the relationship between the two data sets. Log transformation of some data sets was necessary to normalize the data. Using simple linear regression between laboratory and PXRF data, an R2 of 0.88 was produced for the gypsum data, and an R2 of 0.839 was produced for salinity data. Similarly, simple linear regression for laboratory-quantified gypsum vs. PXRF S produced an R2 of 0.91. Multiple linear regression of laboratory quantified gypsum vs. both PXRF S and Ca produced an R2 of 0.91, and 0.8669 for laboratory determined EC (dS m-1) vs. PXRF Cl, S, Ca, and K. No significant differences were observed between model generation and validation data sets. Overall, PXRF shows great promise for the direct quantification of soluble salts in soils.
