A System to Evaluate the Performance of Insulated Tubulars in Steam Injection Wells
Authors: Eisenhawer Stephen W. , Johnson Donald R. , Vigil William J. , Meldau Robert F. , Gilby Doug
Published: December 2007

The efficiency of a thermal enhanced oil recovery project with surface steam generation can be significantly increased by using insulated tubing in the injection wells. In order to evaluate the performance of various insulated tubulars it is necessary to obtain detailed temperature measurements and accurate heat loss data under actual in—field conditions. A system to provide this information has been developed and is in operation at the Aberfeldy steam pilot near Lloydminster, Saskatchewan, Canada.

Temperature measurements are made using thermocouples inside and on the outer wall of the injection string; on the outside of the casing, and in a set of three 25 mm (1 in) ID thermowells attached to the casing. In addition, thin film heat flux sensors are bonded directly to the wall of the injection string. A probe system was designed to measure circumferential temperature variations in the thermowells at depths down to 100 m. This makes it possible to obtain detailed axial temperature profiles. Anticipated hot spots on an insulated joint will be detected in this manner. All of the data is recorded on a datalogger and detailed analysis is performed on a computer system.

To date a short test has been carried out using bare 60 mm (2–3/8 in) injection string tubing. This bare string provides data for comparison with insulated strings. High resolution radial temperature profiles were obtained during this test. Variations in heat loss from the string as functions of time and operating conditions have also been successfully monitored. Heat losses from the string during initial start up on the order of 1.0 Kw/m (1050 Btu/hr-ft) were observed with the heat flux sensors. This is in good agreement with the expected heat loss. The heat flux sensors make it possible to both simplify and improve the determination of insulated tubular thermal performance.
Nitrogen for the Enhanced Recovery of Oil and Gas
Authors: Clancy J. P. , Gilchrist R. E. , Kroll D. E.
Published: December 2007

Nitrogen, produced by air separation and compressed to high pressure has many potential applications in enhanced oil and gas recovery. Possible applications include using nitrogen as a driving gas for costly and limited carbon dioxide, and in some cases for miscible displacement. The displacement of gas cap gas, the production of attic reservoirs, the cycling of condensate reservoirs, the maintenance of reservoir pressure and other applications can also be considered. Nitrogen can be produced at almost any reservoir site using proven technology and various energy sources. Depending upon the pressure, quantities, and location, nitrogen may cost one-quarter (1/4) to one-half (1/2) the price of natural gas. Using existing technology, nitrogen can be separated from the produced associated natural gas.
Pump-Off Controller Application for Midway-Sunset Cyclic Steam Operations
Authors: Acton Jeff F.
Published: December 2007

This paper proposes the use of pump-off controllers to optimize cyclic steam enhanced recovery. This is accomplished by allowing pumping units to operate at constant higher strokes per minute while letting the pump-off controller system monitor the fluid pound dictated by changing well conditions. This concept alleviates the need to change pumping unit speeds as the cycle progresses while ultimately increasing net oil gained per cycle.
The Development of a Conceptual Model of the Rotorua-Whakarewarewa Geothermal Reservoir, New Zealand
Authors: Donaldson Ian G. , Grant Malcolm A.
Published: December 2007

It is now considered that extraction of energy and fluid from a hot water aquifer underlying the city of Rotorua, New Zealand, is adversely affecting the surface geothermal features in the neighboring Whaka-rewarewa Tourist Reserve. In this paper, we look at the spectrum of data available that may provide us with background information about this system. An analysis of this data enables us to establish a conceptual model of the total Rotorua-Whakarewarewa geothermal reservoir. This may help in the setting up of a management plan that will permit the continuing extraction of energy by residents while giving some degree of protection to the features in the Tourist Reserve.
Tertiary Oil Recovery by Flooding with Aqueous Chemical Solutions
Authors: Kamath Krishna I. , Comberiati Joseph R. , Zammerilli Anthony M. , Kyle Clyde C. , Taylor Billy D.
Published: December 2007

The ability of a water-soluble (oil-insoluble), detergent alkylate sulfonate to recover tertiary oil from flooded-out Berea sands is traced to the presence, in it, of minor but as yet chemically unidentified components. The immiscible displacement process with dilute aqueous solutions of the sulfonate is found to be independent of conventional mobility control, and to depend only on the amount of sulfonate (not concentration) in the displacing phase.

Published: December 2007

A two-dimensional, multicomponent, multiphase, compositional reservoir simulator has been developed, tested, and applied to micellar/polymer flooding. The simulator is even more complete in its physical description than the 1-D version previously published.1,2 The simulator is described and discussed. Applications to various field scale conditions are illustrated. Factors simulated include reservoir heterogeneity, crossflow, dispersion, injection rate, and various process variables such as slug size, polymer drive grading and size, salinity gradient, and mobility ratio.

Authors: Moghadasi J. , Kalantari-Dahaghi A. M. , Gholami V. , Abdi R.
Published: December 2007

Although CO2 injection is one of the most common enhanced oil recovery methods, that is widely used in Iranian reservoirs, it may change the reservoir fluid properties and cause some problems such as Asphaltene precipitation which will result in reduction of injectivity and productivity of oil wells and plugging wellbore and production facilities.

This paper describes the effect of miscible CO2 flood on Asphaltene precipitation in angestan reservoir of Kupal field in southwest of Iran. The amount of Asphaltene precipitation in the mixture of oil and CO2 gas was measured by using PVT test and the mechanism of precipitation under the reservoir conditions was obtained by high pressure core flood test. Then, the experimental results were compared with the ones obtained from available asphaltene precipitation models.
Associated Gas Treatment On Site
Authors: Moins George
Published: December 2007

Associated gases are being collected and processed for natural gas liquids (NGL) recovery and market gas production in more and more fields, both onshore and offshore, for a better valorization of natural resources. The economical background of associated gas treatment is discussed and available methods for NGL recovery are reviewed and evaluated against technical criteria.

Economics of NGL recovery projects are provided for three typical examples: a major onshore project, a combination offshore-onshore project, and an offshore project.
Impact of exotic invasive species in the cooling network of the Cartuja'93 technological park (Seville)
Authors: Escot C. , Basanta A. , Diaz A.
Published: December 2007

EMASESA has been monitoring the biological colonization in the Cartuja Island raw water network since 2001. Water from the Guadalquivir River dock, which circulates through this network, is meant for irrigation of the green areas and for the air conditioning of the buildings in the Cartuja 93 Science and Technology Park. The results of this study have highlighted that in the biological colonization of the distribution network three exotic invasive species are involved: the bivalves Mytilopsis leucophaeata and Corbicula fluminea, along with the hydrozoan Cordylophora caspia. The colonization is principally registered at the beginning of the network in the pumping station facilities. The C. caspia and M. leucophaeata have experienced the biggest growth, and the hydrozoan has had the biggest effect on the distribution network. The biological growth in the network has been tackled in two ways: (1) eliminating the existing colonization i.e. acting on the adult specimens while manually cleaning the larger diameter pipes and (2) preventing new outbreaks by using a non-oxidizing and fast hydrolysing biocide and using a TBT-free anti-fouling paint.
A Comparative Analysis of Costs to Government for Home Care and Long-term Residential Care Services, Standardized for Client Care Needs
Authors: Hollander Marcus J. , Chappell Neena L.
Published: December 2007

This paper reports on the results of analyses using administrative data from British Columbia for 10 years from fiscal 1987/1988 to 1996/1997, inclusive, to examine the comparative costs to government of long-term home care and residential care services. The analyses used administrative data for hospital care, physician care, drugs, and home care and residential long-term care. Direct comparisons for cost and utilization data were possible, as the same care-level classification system is used in BC for home care and residential care clients. Given significant changes in the type and/or level of care of clients over time, a full-time equivalent client strategy was used to maximize the accuracy of comparisons. The findings suggest that, in general, home care can be a lower-cost alternative to residential care for clients with similar care needs. The difference in costs between home care and residential care services narrows considerably for those who change their type and/or level of care, and home care was found to be more costly than long-term institutional care for home care clients who died. The findings from this study indicate that with the appropriate substitution for residential care services, in a planned and targeted manner, home care services can be a lower-cost alternative to residential long-term care in integrated systems of care delivery that include both sets of services.
Linguistic, Academic, and Cognitive Benefits of French Immersion
Authors: Lazaruk Wally
Published: December 2007

Abstract:

A survey of research on French as a second language (FSL) education in Canada suggests that French immersion (FI) students enjoy significant linguistic, academic, and cognitive benefits. We organize our summary of the advantages of FI around these three themes, comparing students’ proficiency in French and English across various FI programs, and assessing their overall academic achievement. Our review shows that FI programs enable students to develop high levels of proficiency in both French and English, at no cost to their academic success. Cognitive research associates bilingualism with heightened mental flexibility and creative thinking skills, enhanced metalinguistic awareness, and greater communicative sensitivity. Because cognitive benefits are contingent on a bilingual learner's proficiency in both languages, it may be that FI programs, which promote heightened proficiency in both French and English, foster in their students an underlying cognitive advantage.
Trait differences between grass species along a climatic gradient in South and North America
Authors: Oyarzabal Mariano , Paruelo José M. , del Pino Federico , Oesterheld Martín , Lauenroth William K.
Published: December 2007

Question: Are trait differences between grasses along a gradient related to climatic variables and/or photosynthetic pathway?

Location: Temperate grassland areas of South and North America.

Methods: In a common garden experiment, we cultivated C3 and C4 grasses from grasslands under different climatic conditions, and we measured a set of 12 plant traits related to size and resource capture and utilization. We described (1) interspecific plant trait differences along a climatic gradient defined by the precipitation and temperature at the location where each species is dominant and (2) the association between those plant trait differences and the photosynthetic pathway of the species.

Results: Trait differences between grasses were related to the precipitation at the area where each species is dominant, and to the photosynthetic pathway of the species. Leaf length, leaf width, plant height, leaf area per tiller, specific leaf area, leaf δ13C ratio, and nitrogen resorption efficiency increased while leaf dry matter content and nitrogen concentration in senesced leaves decreased as precipitation increased. A proportion of these changes along the gradient was related to the photosynthetic pathway because dominant grass species in cold areas with low precipitation are mainly C3 and those from warm and wet areas are C4.

Conclusions: A previous worldwide analysis showed that traits of graminoid species measured in situ changed slightly along climatic gradients (< 10% variance explained). In contrast, under a common environment we observed that (1) grass traits changed strongly along a climatic gradient (30‐85% variance explained) and, (2) a proportion of those changes were related to the association between photosynthetic pathway of the species and precipitation.

Common‐ and multi‐offset ground‐penetrating radar study of a Roman villa, Tourega, Portugal
Authors: Berard Brooke A. , Maillol J. M.
Published: December 2007

A ground‐penetrating radar (GPR) survey was conducted at the site of the first to fourth century AD Roman villa of Tourega, near Évora, Alentejo region, Portugal. This site has been partially excavated, revealing a bathhouse complex consisting of a tank reservoir, multiple bathing rooms and a major corridor. The excavated portion of Tourega provides direct archaeological feedback as to the size, shape, depth and orientation of structures revealed by GPR surveys. A 4500 m2 area surrounding the known site was surveyed using common‐offset 500 MHz and 200 MHz pseudo‐three‐dimensional acquisition. Amplitude time‐slice analysis reveals a large number of well‐defined additional structures confirming a much broader extension of the site. For shallow buried rectilinear structural targets, the high frequency 500 MHz common‐offset data provide excellent imaging. However, limited depth penetration at 500 MHz necessitated a lower frequency of investigation; therefore 200 MHz common‐ offset and multi‐offset data were also acquired. Two 200 MHz multi‐offset GPR profiles were obtained over the large double‐walled structure identified on the time‐slices, acquired using a newly proposed multi‐offset acquisition technique – rapid multi‐offset acquisition. This acquisition technique uses the existing single‐channel GPR system, is extremely cost‐effective, and easily acquires a high fold. Rapid multi‐offset acquisition provides an average time saving up to five times that of stationary multi‐offset profiling. The 200 MHz multi‐offset profiles provide a greater depth penetration and enhanced structural detail (i.e. improved imaging of dipping structures) than comparable 200 MHz common‐offset profiles. Post‐stack, inverse‐Q filtering increases vertical resolution and interpretability of the multi‐offset sections via removal of wavelet dispersion. Although multi‐offset data are less feasible for characterizing this site in three dimensions because of the large time commitment in data collection, two multi‐offset profiles over key structures of interest improved the final site interpretation, with enhanced image quality and higher resolution than comparable common‐offset profiles. The combined results of the multi‐offset survey with a common‐offset grid should encourage a more frequent use of multi‐offset data at archaeological sites when the depth extent of the archaeological site is uncertain.

Content and mean polymerization degree of procyanidins in extracts obtained from clear and cloudy apple juices
Authors: Huemmer Wolfgang , Dietrich Helmut , Will Frank , Schreier Peter , Richling Elke
Published: December 2007

The polyphenol profile of apples and that of technologically differently treated apple juices has already been studied thoroughly; nevertheless, the content of polymeric procyanidins has not received much attention up to date. Therefore, procyanidins in extracts made from six blended apple juices and two authentic clear as well as cloudy apple juices (Malus domestica cv. Bohnapfel and Bittenfelder) were investigated. Our determinations revealed significant differences in the total procyanidin content between apple juice extracts obtained from clear and the corresponding cloudy juices under study. Depending on the apple cultivars used average amounts of total procyanidin content determined in the extracts made from clear and cloudy juices ranged from 28.4 ± 4.4% to 49.0 ± 5.7% and from 48.3 ± 0.3% to 60.6 ± 0.3%, respectively. As the mean degree of polymerization (DPm) is supposed to have an influence on bioavailability and toxicity on different cells lines used in in vitro systems, the average degree of polymerization of the juices under examination were determined. Depending on the cultivar used and the technology of juice processing the DPm ranged between 3.0 and 13.4.
Identification of metabolic fluxes in hepatic cells from transient 13C‐labeling experiments: Part I. Experimental observations
Authors: Hofmann Ute , Maier Klaus , Niebel Anja , Vacun Gabriele , Reuss Matthias , Mauch Klaus
Published: December 2007

An experimental set‐up for acquiring metabolite and transient 13C‐labeling data in mammalian cells is presented. An efficient sampling procedure was established for hepatic cells cultured in six‐well plates as a monolayer attached to collagen, which allowed simultaneous quenching of metabolism and extraction of the intracellular intermediates of interest. Extracellular concentrations of glucose, amino acids, lactate, pyruvate, and urea were determined by GC–MS procedures and were used for estimation of metabolic uptake and excretion rates. Sensitive LC–MS and GC–MS methods were used to quantify the intracellular intermediates of tricarboxylic acid cycle, glycolysis, and pentose phosphate pathway and for the determination of isotopomer fractions of the respective metabolites. Mass isotopomer fractions were determined in a transient 13C‐labeling experiment using 13C‐labeled glucose as substrate. The absolute amounts of intracellular metabolites were obtained from a non‐labeled experiment carried out in exactly the same way as the 13C‐labeling experiment, except that the media contained naturally labeled glucose only. Estimation of intracellular metabolic fluxes from the presented data is addressed in part II of this contribution. Biotechnol. Bioeng. 2008;100: 344–354. © 2007 Wiley Periodicals, Inc.

Authors: Mao Renfang , Fan Yihui , Chen Feng , Sun Donglin , Bai Jing , Fu Songbin
Published: December 2007

It has been shown that the polymorphisms of Methylenetetrahydrofolate reductase (MTHFR) gene are associated with susceptibility to several disorders including hyperhomocysteinemia, vascular disease, birth defect, and certain cancers, and exhibit great diversities among various populations. The aim of this study was to investigate the prevalence of two common non‐synonymous single nucleotide polymorphisms (i.e., C677T and A1298C) at MTHFR gene in 13 Chinese populations. A total of 1015 healthy individuals from 13 populations distributed widely from north to south in China were studied. DNA samples were isolated from peripheral blood samples and genotyped using polymerase chain reaction‐restriction fragment length polymorphism. For C677T polymorphism, the frequency in Chinese of CC homozygous was 42.4%; CT heterozygous was 49.8%; and TT homozygous was 7.9%. For A1298C, AA homozygous was 39.2%; AC heterozygous was 38.6%; and CC homozygous was 22.2%. The allelic frequency of 677T and 1298C was 32.8 and 41.5%, respectively, and each allele frequency had significant variance in 13 Chinese populations. The frequency of the 677T allele among southern populations was 30.7% compared to 38.0% among northeastern and 30.5% among northwestern populations. The difference was statistically significant (p < 0.01). The frequency of 1298C mutation in southerns was 58.9% whereas in northeasterns it was 24.0% and 37.6% in northwesterns. This was also statistically significant (p < 0.01). The MTHFR C677T and A1298C sites were in linkage disequilibrium in the Chinese population revealed by our data.

Authors: Martin Jack L. , Pratsos Antonis , Magargee Edward , Mayhew Kim , Pensyl Catherine , Nunn Mary , Day Francis , Shapiro Timothy
Published: December 2007

Objective: This prospective randomized trial compared the Angio‐Seal VIP™ with Perclose Proglide™ and to manual compression with respect to time to hemostasis and ambulation, patient satisfaction, and vascular complications following percutaneous coronary intervention (PCI). Background: The use of arterial closure devices for the reduction of vascular complications following PCI remains controversial. There have been no head to head trials comparing these most commonly used arterial closure devices following PCI. Methods: Two hundred patients undergoing PCI were randomized to manual compression, Perclose Proglide™ or Angio‐Seal VIP™. Ambulation was allowed 3 hr after Perclose Proglide™ or Angio‐Seal VIP™ and 6 hr after compression. Results: There were 10 failures to deploy Perclose Proglide™ and none for Angio‐Seal™ (P < 0.01). Time to hemostasis was significantly shorter with Angio‐Seal VIP™ compared with Perclose Proglide™ (5.3 vs. 46.8 min, P < 0.01). Time to ambulation was shorter with Angio‐Seal VIP™ than with Perclose Proglide™ (261 vs. 334 min, P < 0.05) and the time to ambulation, as expected, was longest with compression (943 min, P < 0.01 vs. Angio‐Seal VIP™ and Perclose Proglide™). Delay in ambulation was higher with Perclose Proglide™ than with Angio‐Seal VIP™ (18 vs. 9, P < 0.01). There was no significant difference in major vascular complications between groups. Compared with compression, patient discomfort was significantly improved with Angio‐Seal™ (1.5 vs. 2.0, P < 0.01), but not with Perclose Proglide™. Conclusion: The Angio‐Seal VIP™ device has a high rate of deployment success, which is significantly better than that of Perclose Proglide™. Angio‐Seal VIP™ allows for earlier hemostasis and ambulation compared with both compression and Perclose Proglide™ and is associated with greater patient satisfaction compared with compression. © 2008 Wiley‐Liss, Inc.
New exploratory clustering tool
Authors: Acar Evrim , Bro Rasmus , Schmidt Bonnie
Published: December 2007

This paper describes a clustering method on three‐way arrays making use of an exploratory visualization approach. The aim of this study is to cluster samples in the object mode of a three‐way array, which is done using the scores (sample loadings) of a three‐way factor model, for example, a Tucker3 or a PARAFAC model. Further, tools are developed to explore and identify reasons for particular clusters by visually mining the data using the clustering results as guidance. We introduce a three‐way clustering tool and demonstrate our results on a metabolite profiling dataset. We explore how high performance liquid chromatography (HPLC) measurements of commercial extracts of St. John's wort (natural remedies for the treatment of mild to moderate depression) differ and which chemical compounds account for those differences. Using common distance measures, for example, Euclidean or Mahalanobis, on the scores of a three‐way model, we verify that we can capture the underlying clustering structure in the data. Beside this, by making use of the visualization approach, we are able to identify the variables playing a significant role in the extracted cluster structure. The suggested approach generalizes straightforwardly to higher‐order data and also to two‐way data. Copyright © 2007 John Wiley & Sons, Ltd.
A Versatile Ditopic Ligand System for Sensitizing the Luminescence of Bimetallic Lanthanide Bio‐Imaging Probes
Authors: Chauvin Anne‐Sophie , Comby Steve , Song Bo , Vandevyver Caroline D. B. , Bünzli Jean‐Claude G.
Published: December 2007

The homoditopic ligand 6,6′‐[methylenebis(1‐methyl‐1H‐benzimidazole‐5,2‐diyl)]bis(4‐{2‐[2‐(2‐methoxyethoxy)ethoxy]ethoxy}pyridine‐2‐carboxylic acid) (H2LC2) has been tailored to self‐assemble with lanthanide ions (LnIII), which results in the formation of neutral bimetallic helicates with the overall composition [Ln2(LC2)3] and also provides a versatile platform for further derivatization. The grafting of poly(oxyethylene) groups onto the pyridine units ensures water solubility, while maintaining sizeable thermodynamic stability and adequate antenna effects for the excitation of both visible‐ and NIR‐emitting LnIII ions. The conditional stability constants (log β23) are close to 25 at physiological pH and under stoichiometric conditions. The ligand triplet state features adequate energy (0‐phonon transition at ≈21 900 cm−1) to sensitize the luminescence of EuIII (Q=21 %) and TbIII (11 %) in aerated water at pH 7.4. The emission of several other VIS‐ and NIR‐emitting ions, such as SmIII (Q=0.38 %) or YbIII (0.15 %), for which in cellulo luminescence is evidenced for the first time, is also sensitized. The EuIII emission spectrum arises from a main species with pseudo‐D3 symmetry and without coordinated water. The cell viability of several cancerous cell lines (MCF‐7, HeLa, Jurkat and 5D10) is unaffected if incubated with up to 500 μM [Eu2(LC2)3] during 24 h. Bright EuIII emission is seen for incubation concentrations above 10 μM and after a 15‐minute loading time; similar images are obtained with TbIII and SmIII. The helicates probably permeate into the cytoplasm of HeLa cells by endocytosis. The described luminescent helical stains are robust chemical species which remain undissociated in the cell medium and in presence of other complexing agents, such as edta, dtpa, citrate or L‐ascorbate. Their derivatization, which would open the way to the sensing of targeted in cellulo phenomena, is currently under investigation.
Synthesis of Nearly Enantiopure Allylic Amines by Aza‐Claisen Rearrangement of Z‐Configured Allylic Trifluoroacetimidates Catalyzed by Highly Active Ferrocenylbispalladacycles
Authors: Jautze Sascha , Seiler Paul , Peters René
Published: December 2007

The development of the first highly active enantioselective catalyst for the aza‐Claisen rearrangement of Z‐configured allylic trifluoroacetimidates generating valuable almost enantiopure protected allylic amines is described. Usually Z‐configured allylic imidates react significantly slower than their E‐configured counterparts, but in the present study the opposite effect was observed. Z‐Configured olefins have the principal practical advantage that a geometrically pure CC double bond can be readily obtained, for example, by semihydrogenations of alkynes. Our catalyst, a C2‐symmetric planar chiral bispalladacycle complex, is rapidly prepared from ferrocene in four simple steps. Key step of this protocol is an unprecedented highly diastereoselective biscyclopalladation providing dimeric macrocyclic complexes of fascinating structure. In the present study as little as 0.1 mol % of catalyst precursor were sufficient for most of the alkyl substituted substrates to give in general almost quantitative yields. NMR investigations revealed a monomeric structure for the active catalyst species. The bispalladacycle can also be used for the formation of almost enantiomerically pure allylic amines (ee≥96 %) substituted with important functional groups such as ester, ketone, ether, silyl ether, acetal or protected amino moieties providing high‐added‐value allylic amine building blocks in excellent yield (≥94 %). The preparative advantages should render this methodology highly appealing as a practical and valuable tool for the formation of allylic amines in target oriented synthesis.
