Pilot Installation of a Deep Gas Lift System Conveyed with Coiled Tubing Catenary Method Increases Production of an Idle Well in Brunei
Authors: Tahir H. Md , Whittaker A.. , Shanmugam N.. , Tapia W. R. 
Published: October 2016

Abstract
An oil well located offshore Southeast Asia, was completed with a dual string and after 20 years of production the drawdown decreased significantly even with gas lift mandrels located in the long string, 480m (1575ft.) above the lowest producing zone. A deep gas lift (DGL) system was installed based on field data that indicated the production could be improved by increasing the drawdown to optimize the gas lift performance.
One of the main limitations was the depth of the production packer for the gas injection production. The deep gas lift system was selected as it enables the gas injection point to be moved deeper into the well, which in turn results in the ability to create a greater drawdown. The lowermost gas lift mandrel was straddled with two packers and a crossflow assembly that provided dual flow paths in a single system as well as suspending 350m (1148ft.) of 1.5in coiled tubing (CT) that acted as the injection string to a predetermined depth.
The operation was the first of its kind in which the DGL system was conveyed with a CT Catenary system on board a dynamically positioned vessel (DP2); this enabled flexibility in deployment of the long bottomhole assemblies in small offshore platforms without the presence of a crane. For this operation, modifications were required in the original CT equipment to maintain well integrity, providing double barriers at every step of the installation. The DGL system was successfully and safely installed in a live well in 3 days. After its installation, the production rate increased tremendously.
Similar operations will benefit from understanding the rationale in the selection of the solution, the details of the installation with the CT catenary system, the barrier systems put in place during the open-hole installation, the depth correlation methods and the lessons learned.

Published: October 2016

Abstract
A prolonged period of relatively low oil prices has resulted in an industry-wide push to utilise field development technologies that provide better returns on investment. For deepwater and long distance tieback developments, both pipeline and flow assurance related expenses constitute the major components of both CAPEX and OPEX figures for the development.
This paper presents how subsea dehydration technology could be used as a novel solution to reduce development costs by solving pipeline issues related to multiphase flow. It also outlines the two potential application scenarios for subsea dehydration, with Specific focus on the hybrid topsides-subsea development scenario. Key features of the subsea dehydration system are provided, with descriptions of the main subsea technology components.

Abstract
Tunu is a giant gas field located in Delta Mahakam, East Kalimantan, Indonesia operated by Total E&P Indonesie. The field development targets two domains: Tunu Shallow Zone (TSZ) and Tunu Main Zone (TMZ). The primary objective of TSZ completion is to have a cost effective sand control methodology to ensure economic vialibility of the wells since TSZ consist of small elliptical shaped deltaic sand bodies containing low reserve gas pockets with a typically short production life.
Multi zone single trip gravel pack (MZ-STGP) systems have been utilized as sand control completion methodology. Technical limitations of these techniques in terms of zone spacing, number of zones and well deviations drove the need developping an alternative completion technique. Using short screen assembly and open-hole isolation technology, a unique multi zone open hole stand alone screen (MZ- SAS) system was developed.
The initial development consists of 14 wells. Both low and high angle deviated wells, numbers of different completion jewelries and different type of reservoir drill-in fluids (RDIF) have been used over the initial phase of the development. The objective of this paper is to review the evolution and improvements in the drilling, fluid, completion and specific post well completion strategy. This has provided a best practice for future completions in the development of similar reservoirs in the portfolio.

Authors: Aniis Kavi , Kcp Rajamanikandan , Prasanth D Arvind 
Published: October 2016

<p>ABSTRACT<br />Objective: Beta-lactams are the group of antibiotics that contain a ring called as “beta-lactam ring,” which is responsible for the antibacterial activity.<br />The presence of resistance among Gram-negative organisms is due to the production of beta-lactamases enzymes that hydrolysis the beta-lactam ring<br />thereby conferring resistance to the organism. This study is undertaken to determine the prevalence of extended-spectrum beta-lactamase (ESBL)<br />producing Gram-negative organism from clinical samples.<br />Methods: A total of 112 clinical samples were taken for this study. The combined disc synergistic test (CDST) was used for the phenotypic detection<br />of ESBL producers from the clinical samples. The genotypic identification of ESBL producers was carried out by alkaline lysis method by isolation of<br />plasmid DNA.<br />Result: A total of 87 bacterial isolates were isolated and identified. Among them, Klebsiella (41%) was the predominant organism followed by<br />Escherichia coli (33%), Proteus (10%), Pseudomonas (10%), and Serratia (6%). Among the various bacterial isolates, Klebsiella showed a higher<br />percentage of resistance. The CDST showed that 8 isolates of Klebsiella, 3 isolates of E. coli, and 1 isolate of Pseudomonas were found to be ESBL<br />producers. The genotypic confirmation showed that the two bacterial isolates, namely, Klebsiella and E. coli were found to possess temoniera (TEM)<br />gene which was the 400-500 bp conferring resistance to the antibiotics.<br />Conclusion: The results of this study suggest that early detection of ESBL producing Gram-negative organism is a very important step in planning the<br />therapy of patient in Hospitals. CDST continues to be a good indicator in the detection of ESBL producers.<br />Keywords: Beta-lactamases, Gram-negative bacilli, Extended-spectrum beta-lactamase, Resistance, Combined disc synergistic test.</p><p> </p>

Authors: Aguilar Fuentes Sonia Isabel , Cardona Arango Doris 
Published: October 2016

ResumenObjetivo: Explorar la seguridad económica de los adultos mayores en Medellín, Colombia, así como sus fuentes de ingreso y transferencias económicas, desde una mirada comprensiva. Materiales y métodos: Estudio cualitativo exploratorio de fuente primaria, con selección por bola de nieve por medio del método histórico-hermenéutico. Se entrevistaron quince adultos mayores y cinco especialistas en el tema, a los cuales se les indagó por aspectos relacionados con sus condiciones económicas y se analizó la información, como una teoría fundamentada, donde emergen categorías de los textos. Resultados: Los mayores se sienten inseguros económicamente al no contar con ingresos fijos y suficientes que les permitan vivir de manera autónoma e independiente; menos de una tercera parte cuenta con ingresos provenientes de un empleo, el cual es informal en la mayoría de los casos Por otro lado, las transferencias por pensión y jubilaciones están determinadas por la ocupación y tipo de vinculación en su anterior vida laboral y muchos de ellos deben recurrir a las transferencias económicas de sus familiares. Conclusión: Los adultos mayores entrevistados ven comprometida su seguridad económica por no contar con un ingreso económico para la cobertura de necesidades básicas, ya que una gran mayor parte de ellos carecen de ingresos fijos, que los lleva a la informalidad para vivir el día a día, conscientes de que cada vez se envejecerá más, aumentará la dificultad para seguir laborando y se reducen los espacio para laborar y por ello deben depender del Estado o la familia. AbstractObjective: To explore the economic security of the elderly in Medellin, Colombia as well as their sources of income and economic transfers from a comprehensive perspective. Materials and methods: An exploratory qualitative study of primary source with selection by snowball through historical hermeneutic method was conducted. 15 seniors and 5 specialists in the field selected by snowball were interviewed and asked for aspects related to their economic conditions. The given information was analyzed, as a grounded theory, where categories from the texts emerge. Results: Elderly people feel insecure financially because they do not have fixed and sufficient income to live autonomously and independently. Less than one-third have income from employment, which in most cases is informally. On the other hand, transfers from pension and retirement benefits are determined by the occupation and type of labor relationship in their previous jobs and many of them must rely on financial transfers from their families.

Identification of Rare Recombinants Leads to Tightly Linked Markers for Nematode Resistance in Peanut
Authors: Chu Y. , Gill R. , Clevenger J. , Timper P. , Holbrook C. C. , Ozias-Akins P 
Published: October 2016

ABSTRACTStrong host resistance to root-knot nematode (RKN; Meloidogyne arenaria) introgressed from a wild diploid species to cultivated peanut was previously shown to be located on a large chromosomal region of linkage group A09. Little to no recombination in mapping populations has hindered fine mapping of the resistance genes. In order to further delineate the introgressed region, additional polymorphic markers were added to the linkage group A09 using a recombinant inbred line population developed from Gregory x Tifguard in which Gregory is the susceptible parent and Tifguard is the resistant parent harboring the alien introgression. Map distance within the introgressed region based on this population increased to 8 cM compared with zero recombination in an earlier generation. Lines with rare recombination within this introgressed region were phenotyped and it was demonstrated that one portion of the introgressed region confers moderate resistance while a smaller, distal portion confers strong resistance to RKN. Molecular markers associated with the introgressed region conferring strong resistance can be deployed in peanut breeding programs to improve selection for RKN resistance.

ABSTRACT
We present the discovery of a hot Jupiter transiting the V = 9.23 mag main-sequence A-star KELT-17 (BD+14 1881). KELT-17b is a

,

hot-Jupiter in a 3.08-day period orbit misaligned at −115.°9 ± 4.°1 to the rotation axis of the star. The planet is confirmed via both the detection of the radial velocity orbit, and the Doppler tomographic detection of the shadow of the planet during two transits. The nature of the spin–orbit misaligned transit geometry allows us to place a constraint on the level of differential rotation in the host star; we find that KELT-17 is consistent with both rigid-body rotation and solar differential rotation rates (

at

significance). KELT-17 is only the fourth A-star with a confirmed transiting planet, and with a mass of

, an effective temperature of 7454 ± 49 K, and a projected rotational velocity of

it is among the most massive, hottest, and most rapidly rotating of known planet hosts.
NEUTRON-CAPTURE ELEMENT ABUNDANCES IN MAGELLANIC CLOUD PLANETARY NEBULAE*

ABSTRACT
We present near-infrared spectra of 10 planetary nebulae (PNe) in the Large and Small Magellanic Clouds (LMC and SMC), acquired with the FIRE and GNIRS spectrometers on the 6.5 m Baade and 8.1 m Gemini South Telescopes, respectively. We detect Se and/or Kr emission lines in eight of these objects, the first detections of n-capture elements in Magellanic Cloud PNe. Our abundance analysis shows large s-process enrichments of Kr (0.6–1.3 dex) in the six PNe in which it was detected, and Se is enriched by 0.5–0.9 dex in five objects. We also estimate upper limits to Rb and Cd abundances in these objects. Our abundance results for the LMC are consistent with the hypothesis that PNe with 2–3 M
⊙ progenitors dominate the bright end of the PN luminosity function in young gas-rich galaxies. We find no significant correlations between s-process enrichments and other elemental abundances, central star temperature, or progenitor mass, though this is likely due to our small sample size. We determine S abundances from our spectra and find that [S/H] agrees with [Ar/H] to within 0.2 dex for most objects, but is lower than [O/H] by 0.2–0.4 dex in some PNe, possibly due to O enrichment via third dredge-up. Our results demonstrate that n-capture elements can be detected in PNe belonging to nearby galaxies with ground-based telescopes, allowing s-process enrichments to be studied in PN populations with well-determined distances.
