Surface to Borehole Electromagnetics for 3D Waterflood Monitoring: Results from First Field Deployment (2018)

Abstract Monitoring the waterflood oil recovery process is a difficult task for seismic-based methods in hard carbonate reservoirs. The changes in velocity/density due to water-oil substitution are too small when compared to the errors involved in repeating the measurements. We detail the development of a novel technique based on surface-to-borehole controlled-source electromagnetics (CSEM), which exploits the large contrast in resistivity between injected water and oil to derive 3D resistivity distributions (proportional to saturations) in the reservoir. Surface-to-borehole CSEM responses using surface electric transmitters and borehole EM receivers were modeled using a black-oil simulator for a large oil field in the Middle East. Results indicate that the vertical electric field can be used to detect waterfront changes in 2 and 5-year time-lapse scenarios. A surface-to-borehole acquisition system was engineered comprising the development of a powerful, custom-made electric transmitter (2000V/500A) and borehole electric and magnetic field sensors. The surface-to-borehole 3D CSEM technology was deployed for the first field trial in the same well used for the modeling study. The field demonstration was carried out in 2017 comprising 144 permanent surface electrodes drilled in a radial configuration around a vertical observation well. The current electrodes were designed in an L pattern to form 48 inline (radial) and 48 cross-line (tangential) dipoles at a nominal range of 600m to 3,500m from the vertical observation well. A wireline sensor array comprising two vertical electric and two vertical magnetic field sensors recorded the EM signal transmitted from the surface in regularly spaced positions in the reservoir section. Surface measurements of transient EM (TEM), CSEM and magnetotellurics (MT) were recorded together with the borehole acquisition to characterize the overburden and the shallow subsurface. The acquired dataset was processed to increase the signal/noise content of the data as well as to correct for casing effects and surface distortions. A marked asymmetry of the EM responses is recorded in the vicinity of the observation well which translates, after 3D inversion, to resistivity distributions consistent with the saturation/production logs acquired in the nearby wells. The sensitivity of the inversion extends up to 1.8 km away from the observation well. Analysis of the measurement repetition errors compared to predicted EM responses after 2 and 5 years indicates that time-lapse surveys would provide detailed mapping and an independent estimation of saturation variations related to waterflooding. The encouraging results obtained from the first surface-to-borehole CSEM survey in a producing oil field suggests that the technology may become an important tool for analyzing the waterfront evolution in the interwell space. By doing this, the technology is expected to enhance reservoir management and history matching.
A flow-through reaction cell that couples time-resolved X-ray diffraction with stable isotope analysis (2011)

A non-metallic flow-through reaction cell is described, designed for in situ time-resolved X-ray diffraction coupled with stable isotope analysis. The experimental setup allows the correlation of Cu isotope fractionation with changes in crystal structure during copper sulfide dissolution. This flow-through cell can be applied to many classes of fluid–mineral reactions that involve dissolution or ion exchange.
Graph-based Modeling of Building Roofs (2009)

Nowadays there are many applications based on 3D city models. While in the beginning, people were satisfied with about any boundary representation useful for visualization, it has meanwhile become apparent that data capture should focus on highly structured city models. Not only does this improve the usability for certain applications and the usefulness for later processing steps such as 3D generalization, but also, highly structured models are able to support automatic extraction processes by keeping the data interpretation within the bounds of a well-defined, structural model. In this paper, we describe the use of region adjacency graphs for the structured modeling of building roofs. Our basic building blocks are simple building primitives, like flat or ridge shaped volumes, which can be combined to obtain more complex buildings. Additionally, different dormer shapes are defined as superstructures, which can be placed on top of the building primitives. Using the region adjacency graph, modeling translates to the modification of the graph by matching and replacing (sub-) graphs.
Practical and Conceptual Models of Chronic Obstructive Pulmonary Disease (2007)

The challenges of chronic obstructive pulmonary disease and the difficulties in modeling its pathology in vitro and in vivo are substantial. Integration of innate- and adaptive-type responses with processes of scarring and healing do not fit comfortably with some definitions of the immune system, and, instead, this disease is an exemplar of a network-based system that we have named "contiguous immunity." The complicated and highly interconnected networks underpinning many biological processes show features of scale-free networks. Consideration of chronic obstructive pulmonary disease pathology as a scale-free network showing features of contiguous immunity might, in the future, aid identification and targeting of potential key "hubs"-these being principal components of the disease network-manipulation of which may yield successful new therapies.
A single chip DVB receiver for variable-rate QPSK demodulation and forward error correction (2002)

This paper describes a single chip DVB compliant receiver that integrates a variable rate QPSK demodulator with a Viterbi decoder, de-interleaver, and a Reed-Solomon decoder. Using a fixed rate sampling clock it handles continuously variable symbol rate from 1 Msps to 45 Msps. Careful floor planning and flat place and route squeezed the 116,000 nand-equivalent gate design into an area of 38.8 mm/sup 2/. It has been fabricated with a 0.5 /spl mu/m CMOS TLM process. It has been extensively tested in a real-world set-up and proved fully functional.

Formation in the presence of C3 nephritic factor (C3NeF) of an alternative pathway C3 convertase containing uncleaved B. (1976)

C3 nephritic factor (C3NeF) interacts with native C3 and B in the absence of D to generate a C3 convertase containing an uncleaved form of B. Dose response studies with C3NeF and B, respectively, revealed incremental C3 inactivation without loss of B. These findings are in agreement with the previous isolation from such reaction mixtures of a 10S complex containing haemolytically inactive C3 and active B and manifesting C3 convertase activity. Functional contamination of C3 with C3b was negated by demonstrating that pretreatment of C3 with C3bINA had no effect on its subsequent interaction with B and C3NeF to generate C3 convertase activity, while pretreatment of C3b eliminated its effective interaction with B and C3NeF. Relatively higher concentrations of C3bINA present during interaction of C3, B and C3NeF suppressed C3 inactivation, indicating its dependence on amplification by utilization of the initial C3b generated. Trace quantities of D were not found by functional analyses of C3, B and C3NeF and pretreatment of these proteins with a concentration of DFP sufficient to suppress D activity had no effect on their effective interaction. The introduction of D to mixtures of C3NeF, B, and C3 resulted in B clevage and more efficient expression of C3 convertase function as defined by a reduced requirement for C3NeF.
New protein in human blood plasma, rich in proline, with lipid-binding properties. (1976)

A protein that binds to a lecithin-stabilized triglyceride emulsion has been separated from plasma after removal of major lipoprotein classes by ultracentrifugation at density 1.21 g/ml. This protein, rich in proline, has been purified to electrophoretic and immunochemical homogeneity by subsequent gel and ion-exchange chromatography. In native plasma and after purification, it exists as a large particle exceeding 10(6) daltons, but a single component with a molecular weight of about 74,000 is found upon polyacrylamide gel electrophoresis in sodium dodecyl sulfate. Although the purified protein contains very little bound lipid and is not present in the major lipoprotein classes from post-absorptive individuals, it is present in chylomicrons. Its concentration in plasma varies from 12 to 41 mg/dl and is significantly correlated with that of cholesterol in lipoproteins of very low and low density but not in those of high denisty.
High-power flared semiconductor laser amplifiers (1995)

A normal incidence tapered laser amplifier is shown to produce more than 4.5 W optical power at 810 nm in a diffraction-limited beam. A new angled-facet tapered laser amplifier has demonstrated as much as 5 W optical power in a diffraction-limited beam at 810 nm with only a few mWs of coupled input power. Angled-facet laser amplifiers exhibit near-ideal Gaussian beam characteristics. More than 1.9 W CW is obtained in a 970 nm angled-facet tapered laser amplifier. A near-ideal beam quality factor M<SUP>2</SUP> is obtained.
Inhibitors of HIV-1 Tat-Mediated Transactivation (2006)

The transactivation responsive (TAR) RNA is the 5'-leader sequence of the HIV-1 mRNA genome and interacts with the Tat protein during transcription. Tat and the positive transcription elongation factor (P-TEFb) complex bind to TAR to promote efficient transcription of the full-length HIV genome. In the absence of the TAR.Tat.P-TEFb interaction, viral transcription is inefficient, which makes this RNA-protein complex an important target for therapeutic intervention of HIV replication. Inhibitors of HIV-1 transactivation mainly target: 1) TAR RNA, 2) Tat protein and 3) Tat.P-TEFb complex. 1) Compounds against TAR RNA are the most numerous: besides cationic peptides, which were initially developed, recent advances in TAR binding inhibitors include oligonucleotide based-agents and small molecules. Specific research efforts are currently underway to increase cellular uptake. 2) By targeting the Tat protein, both transactivation and other Tat-mediated intra/extracellular functions are affected. Various biopolymeric drugs are reported to effectively inhibit Tat activity. In addition, Tat-targeted antibodies have recently been developed. 3) Intracellular proteins have been discovered to disrupt Tat.P-TEFb interaction, raising the chance of inhibiting HIV-1 transcription via novel mechanisms.
Microstructural and Metal−Support Interactions of the Pt−CeO<sub>2</sub>/C Catalysts for Direct Methanol Fuel Cell Application (2011)

To understand the ceria promotion effect of Pt-CeO(2)/C catalysts on methanol oxidation, microstructural and metal-oxide interactions of Pt-CeO(2)/C catalysts with an atomic ratio of Pt/Ce between 0.14 and 1.4 were systematically examined using high-resolution transmission electron microscopy and electron energy loss spectroscopy (EELS). With an increasing Pt content in the catalysts, Pt particles gradually invaded into the ceria supports and decoration on Pt particles was observed. Simultaneously, the morphology of the supports was dramatically modified with nanocrystalline and amorphous ceria formed between and/or around the Pt particles. It reveals that the Pt-ceria interaction could take place in the catalysts and the influence of the interaction was enhanced with an increasing Pt/Ce ratio. The EELS study demonstrated that the strong Pt-ceria interaction was related to the redox reaction between Pt and ceria. Experimental results also suggested that the strong interaction between Pt and ceria could contribute to the promotion effect of ceria on the oxidation of methanol.

The influence of Metal Dusting on gas reactions (2004)

Abstract Gas composition analysis measurements have been performed in the outlet gas stream of a laboratory metal dusting test furnace in order to study the influence of metal dusting on gas reactions. This analysis has shown that carbon deposition is associated with metal dusting, i.e. the material most severely attacked by metal dusting, catalyses the formation of carbon to the largest extent. Also, metal dusting has not been seen to influence the methanation reactions. A kinetic model has been used to interpret the obtained data with respect to the catalytic activity of several high temperature materials showing that the catalytic activity of the material can vary by orders of magnitude for different reactions.
Predicting Extraversion from Non-verbal Features During a Face-to-Face Human-Robot Interaction (2015)

In this paper we present a system for automatic prediction of extraversion during the first thin slices of human-robot interaction (HRI). This work is based on the hypothesis that personality traits and attitude towards robot appear in the behavioural response of humans during HRI. We propose a set of four non-verbal movement features that characterize human behavior during the interaction. We focus our study on predicting Extraversion using these features extracted from a dataset consisting of 39 healthy adults interacting with the humanoid iCub. Our analysis shows that it is possible to predict to a good level (64 %) the Extraversion of a human from a thin slice of interaction relying only on non-verbal movement features. Our results are comparable to the state-of-the-art obtained in HHI [23].
The use of specialty sand blends to improve casting quality and reduce costs (2014)

Metal casters continually strive to produce the highest quality castings at the lowest competitive cost. Unfortunately they have little control of the cost of the required materials. It's been well established that molding materials such as chromite, zircon, and mullite all exhibit low expansion leading to fewer casting defects related to expansion and better dimensional accuracy. They also have refractory values significantly higher than silica sands. Although some casting applications require the use of 100% specialty sands, there is a significant amount that requires only modest improvements to the properties of silica sand to yield significant casting quality benefits. The present research studies the high temperature physical properties of various blends of Silica sand with Zircon and Chromite sands and defines physical characteristics including expansion, phase transformations, high temperature viscosity and specific heat capacity. The various blends are then evaluated for performance with the use of standard test castings. The test casting used indicates the dimensional stability of the material bends and the dimensional accuracy improvements possible. The research indicates that major advantages are seen in the reduction of expansion and refractory failure related defects. The paper describes characteristics of silica, specialty and sand blends and correlates material properties to quality improvements in defects and dimensional accuracy. The information generated during the research is then used in to provide material dataset information for casting simulation. These simulations are compared and validated using the test casting results to close the loop of defining the causes and solutions to common casting defects. The paper suggest specialty sand levels for several casting applications based on alloy type and casting section size and provides a guide to selection of specialty sands. The research demonstrates the effectiveness of using blends of Silica sand with Zircon and Chromite in the metal casting industry to reduce costs while improving casting quality.

Function of dopachrome oxidoreductase and metal ions in dopachrome conversion in the eumelanin pathway (1988)

The conversion of dopachrome (DC) in the eumelanin pathway has been analyzed to determine the specific product and the role of enzyme control. 5,6-Dihydroxyindole (DHI) and 5,6-dihydroxyindole-2-carboxylic acid (DHICA) were quantitated by HPLC with fluorescent detection, after DC incubation with heated and unheated preparations of B-16 melanoma derived dopachrome oxidoreductase (DCOR). The enzyme-catalyzed reaction produced DHICA as the major product, while DHI formed with the spontaneous reaction. It had originally been suggested that the major product of DC conversion was DHI, with DHICA being formed as a minor product of this conversion [Raper, H.S. (1927) Biochem. J. 21, 89-96]. Copper, nickel, and cobalt ions promoted conversion of DC, with nickel simulating DCOR activity. Removal of free ions from unheated DCOR did not alter DC conversion. We conclude that the major product of DC conversion is DHICA and that DCOR is responsible for this conversion.
Salsa: Leveraging Email to Create a Social Network for the Enterprise (2009)

In this paper we describe Salsa, a plug-in that aggregates social and other content into an email client. Information in Salsa is collected from a variety of sources both inside and outside of email to create a profile for each person in our corporation that contains a photo, organizational details, friends, and an aggregated feed of shared content. Thus, Salsa uses a social networking approach to add social awareness to email. Salsa was deployed internally within our corporation and we trace its growth for six months and describe the results of a targeted user study. Findings demonstrate the extent to which and what type of social awareness is useful in our organization. Use of the aggregated feed is also discussed. In addition to identifying features that are useful for social networks in the enterprise, we explore the benefits of situating this type of application in email.

An Analysis of the Phase Coherent--Incoherent Output of the Bandpass Limiter (1971)

Many applications of the bandpass limiter (BPL) involve coherent demodulation following the limiter. It is shown that as a result of demodulation, the signal mean and the noise variance are direct functions of the phase angle between the signal component passed by the BPL and the coherent reference. As a result, the relationship between the output and input signal-to-noise ratio may be significantly different than that obtained by Davenport for incoherent limiters. A study is also made of the output noise spectral density, and an approximate expressison is derived as a function of the input signal-to-noise ratio, reference phase angle, and the characteristics of the input bandpass filter to the limiter. Also discussed is the first-order signal-plus-noise probability density following coherent demodulation.
Faraday–Michelson system for quantum cryptography (2005)

Quantum key distribution provides unconditional security for communication. Unfortunately, current experimental schemes are not suitable for long-distance fiber transmission because of phase drift or Rayleigh backscattering. In this Letter we present a unidirectional intrinsically stable scheme that is based on Michelson-Faraday interferometers, in which ordinary mirrors are replaced with 90 degree Faraday mirrors. With the scheme, a demonstration setup was built and excellent stability of interference fringe visibility was achieved over a fiber length of 175 km. Through a 125 km long commercial communication fiber cable between Beijing and Tianjin, the key exchange was performed with a quantum bit-error rate of less than 6%, which is to our knowledge the longest reported quantum key distribution experiment under field conditions.
