Russia’s Push for Oil and Gas Growth Stunted by Oversupplied Markets
Authors: Rassenfoss Stephen 
Published: June 2017

Russia has shown a remarkable ability to add oil and gas production in the face of daunting obstacles. It has aggressively expanded in Asia, by rapidly adding production in east Siberia, as it builds pipelines to China and a liquefied natural gas (LNG) facility deep in the Arctic.
A panel of eight leaders from the Russian oil and gas business recently offered an impressive growth story in the face of international trade sanctions and oil prices that sunk into the USD-30/bbl range year ago.
“I have an impression there is a kind of positive mood,” said Alexander Novak, Minister of Energy of the Russian Federation, at a panel session at the IHS Markit CERAWeek conference in Houston. “Prices are becoming stable, more predictable,” he said, but added “there is uncertainty about what comes next.”
As Novak was talking about how the oil-and-gas-driven Russian economy is growing again after a 2-year downturn, oil markets remain weak due to rising US unconventional oil production and lingering high inventories.
The upbeat feeling mentioned by Novak was largely the product of a deal between OPEC and major producers, particularly Russia, to reduce their output.
As of late March, Russia was less than halfway to meeting its pledge to cut output according to a report by Rystad Energy. That study showed that while the largest Russian producers had made cuts equal to about 50% of the 300,000 B/D commitment, those reductions were offset by rising production from independents, particularly by the biggest one in this group, Irkutsk Oil.
“We do not currently see any evidence of Irkutsk Oil or other smaller producers planning to comply with the reduction program targeted, and thus there exists an upside risk to the overall agreement,” said Veronika Akulinitseva, an analyst for Rystad Energy.
Russia remains the biggest supplier of gas to Europe, but an oversupply of gas there means it is scrambling to retain customers demanding lower prices. That is a big change from earlier this decade when gas supplies were tight, and Russia was able to demand top prices.
“Those days are gone now” as the supply gap changed to a supply glut, said Maxim Nechaev, director of consulting in Russia for IHS Markit.
Next-Generation High-Torque Connection for Extended-Reach Wells
Authors: Wilson Adam 
Published: June 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 183415, “Development of Next-Generation High-Torque Oil-Country-Tubular-Goods Premium Connection for Extended-Reach Wells,” by Jerry Buster and Justin Perkins, VAM, and Leonardo Azeredo, Vallourec, prepared for the 2016 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, 7–10 November. The paper has not been peer reviewed.
Long laterals (&gt;6,000 ft) are generating industry challenges that do not exist with shorter lateral wells (2,000–5,000 ft). These longer lateral wells require connections to be exposed to extreme torques, bending, and rotational loads that may render some commercially available connections ineffective in getting the string to location and could compromise sealability. This paper demonstrates how the latest generation of those connections has been tested and validated to extreme loads before being installed in the wellbore.
Introduction
Extended-reach drilling (ERD) has existed since the 1970s, and continuous development has pushed the lengths of the laterals. One of the main challenges in ERD is the drag friction force, mainly because of the string weight during its deployment in deviated sections and long horizontal laterals. As a consequence, conventional standard running practices are not effective for running the casing and liner.
To cope with this and reduce drag, one technical alternative used by operators is string rotation for casing and production liners and even for lower completions. Torque-and-drag analysis is one of the key factors to success on such projects. The longer the horizontal lateral departure, the higher the probability of requiring high torque. Torque also can be used to improve cementing quality, by use of string rotation during cementation.
Because high torque is required for ERD, both the connection and the tubular need to be able to withstand the high torque level and the connection needs to maintain its mechanical and sealability performance.
Methods
Connection Basics. The innovative connection presented in this paper was developed to meet the increasing challenges of ERD. The connection uses a threaded-and-coupled design that allows for maximum tensile efficiency along with maximum torque capacity (Fig. 1). The thread design is a self-locking dovetail concept that has excellent torque capacity. The seal design is a single internal metal-to-metal seal with radius-to-cone contact surfaces. This provides stable seal contact during all loading sequences and robust make-and-break performance.
Surface Modified Nanoparticles as Internal Breakers for Viscoelastic Surfactant Based Fracturing Fluids for High Temperature Operations

Published: June 2017

Abstract
This work presents new surface modified nanoparticles (SMN) that act as internal breakers for viscoelastic surfactant (VES) based fluids. Breaking profile is a key performance feature of a fracturing fluid. In addition to providing greater application latitude at high temperatures, the proposed solution is suited for gas wells or where there is less likelihood of encountering formation crude oil, which could also act as breaker for VES fluids.
The SMNs were prepared by organically modifying nanoparticles with specific surface capping agents that have functional groups with the ability to bind on to their surfaces by chemical or physical interactions. The base VES fluid was prepared from a mixture of sea water, ionic strength agents and a viscoelastic surfactant formulation. Varying amounts of SMNs were added to the base fluid and mixed vigorously to form a homogeneously dispersed fluid. The viscosities of the base fluid without SMNs and with varying amount of SMNs were monitored over time at fixed temperature to observe the breaking profile.
The base fluid consisting of VES dispersed in sea water with ionic strength agent exhibits stable viscosity for prolonged times. Compared to base fluid, addition of bare nanoparticles marginally improves the fluid's viscosity, although, the fluid does not break down to very low viscosity within desired time for convenient flowback operations. Slow viscosity drop is ideal from a fracturing fluid point of view that helps in efficiently placing the proppants inside of created fractures and eventual fluid cleanup. However, without the organically modified nanoparticles, the viscosity is too stable causing the post fracturing cleanup to be too slow. With the SMN the viscosity drop could be controlled and achieved in relatively shorter time. Further, with these breaker control over breaking time is also achievable. The SMN internal breakers interact with the worm like micelles and disrupt the gel formed by these elongated micellar structures.
The surface modified nanoparticles with a functional capping agent alters the way the nanoparticles interact with the wormlike micelles from electrostatic interactions to hydrophobic-hydrophobic interactions. This change provides an efficient mechanism for breaking the VES base fluids in absence of any external breaker with high temperature latitude.

Published: June 2017

SummaryWe report the case of a 77‐year‐old male who had elective duodenopancreatectomy surgery. As part of a multimodal analgesia strategy a continuous infusion of lidocaine was administered peri‐operatively. Surgery was uneventful. On admission to post‐operative Intensive Care Unit (ICU), the patient presented with progressive neurological and haemodynamic failure due to a lidocaine overdose made by an error in the continuous systemic administration. Once the diagnosis was established, an infusion of lipid emulsion resulted in almost immediate haemodynamic recovery; full neurological recovery was however delayed for some hours. Continuous intravenous infusions of lidocaine can lead to systemic toxicity, therefore training in lidocaine administration, diagnosis of toxicity and its management are essential for all staff involved in the care of these patients.
Evaluation of multiple-locus variable-number tandem repeat analysis (MLVA) for genotyping of Escherichia coli isolated from Karaj River

Published: June 2017

Abstract
Most microbiological water quality regulations rely upon the detection of indicators of fecal pollution, such as coliform bacteria, or more specifically Escherichia coli. In order to further understand the source, fate, and implications for water quality regulation, environmental E. coli isolates should be assessed genetically to observe various levels of genotypic diversity. Multiple-locus variable-number tandem repeat (VNTR) analysis (MLVA) is a novel, simple and inexpensive polymerase chain reaction (PCR) based genotyping method which relies on the detection of different copy numbers inside each VNTR locus. In this study, we evaluated MLVA as a tool for the genotyping of E. coli strains of water samples collected from the Karaj River, Iran. Overall, high genetic diversity was observed among environmental E. coli isolates. We also proved the feasibility of MLVA as a complementary or even future replacement genotyping method for the average routine laboratory.

Published: June 2017

Background:
Carbapenems, fluoroquinolones (FQs), and aminoglycosides (AGs) are key drugs for treating Pseudomonas aeruginosa infections, and accumulation of drug resistances make antibiotic therapy difficult.

Methods:
We evaluated 169 patients with imipenem (IPM)-resistant P. aeruginosa and compared patient background and microbiological characteristics between groups with or without FQ resistance. Similar analyses were performed for AG.

Results:
Of the 169 IPM-resistant strains, 39.1% showed resistance to FQs and 7.1% to AGs. The frequency of exposure to FQs within 90 days previously was higher in the group with FQ resistance (45.5%) than in the group without FQ resistance (13.6%). Similarly, 33.3% of patients in the group with AG resistance had been previously administered AGs, higher than the 7.6% of patients without AG resistance. Frequencies of metallo-β-lactamase (MBL) production were higher in the group with FQ or AG resistance (16.7% or 33.3%) than in the group without FQ or AG resistance (2.9% or 6.4%). Multivariate analyses showed exposures to FQs or AGs were related to the respective resistances. MBL production was a common factor for resistance to FQs or AGs, in addition to IPM-resistant P. aeruginosa.

Conclusion:
As well as promoting appropriate use of antibiotics, MBL production should be detected as a target of intervention for infection control.
Desarrollo de la creatividad en la primaria a partir del cuento musical
Authors: Borislavovna Borislova Nadezhda 
Published: June 2017

En años recientes se puede observar un creciente interés por estudiar a las personas creativas desde distintos enfoques y perspectivas, así como el rol y la función que la escuela tiene en todos los niveles educativos para el desarrollo de la creatividad. La creatividad es abordada y estudiada no solamente por los psicólogos, también por educadores, artistas, filósofos, biólogos, empresarios, entre otros. En las primeras dos décadas del siglo XXI, la creatividad se ha vuelto un sinónimo de educación, porque existe una necesidad urgente de educar a nuestros niños y jóvenes de una forma creativa, cambiar los esquemas convencionales por los esquemas del pensamiento divergente, creativo y original que incentive el estudio y desarrollo de la creatividad.Escuchar el cuento musical como parte de las actividades de la educación artística dentro del currículo escolar, es una herramienta muy valiosa para el desarrollo de este potencial. El análisis de los resultados del estudio realizado con 582 niños de 1º a 6º grado de una escuela primaria pública de la ciudad de Puebla, conduce a la necesidad de incluir el cuento musical como parte del currículo de la educación artística. A pesar de una gran variedad del acervo literario-musical que nos ha dejado la historia, sobre todo en los últimos años. El cuento musical, por diversas razones, aún no ha sido explorado y utilizado con fines pedagógicos en la educación primaria. Por lo tanto, este trabajo plantea la necesidad de generar líneas de investigación específicas, enfocadas al estudio y desarrollo de la creatividad a partir de las artes que permitan el desarrollo integral de los niños en la educación básica a nivel primaria, al demostrarse que el cuento musical grabado motivó una transformación estadísticamente considerable del promedio de puntaje de creatividad (mismo que se incrementó de forma estadísticamente significativa en el post-test) en los grados 1º, 2º, 4º y 5º en específico, y al juntar a todos los niños de todos los grados (1º al 6º) que tomaron el test después del cuento musical.

Authors: Trope Michal , Schwartz Joseph S. , Tajudeen Bobby A. , Kennedy David W. 
Published: June 2017

Objective In this report, we presented a rare case of bilateral silent sinus syndrome (SSS) in an otherwise healthy 57-year-old man treated with functional endoscopic sinus surgery (FESS). A systematic review of the literature regarding bilateral SSS was performed. Case Report A 57-year-old man with well-controlled allergic rhinitis in the absence of previous surgery or trauma presented with bilateral SSS, which was successfully managed with bilateral FESS. Methods A medical literature data base search of the terms “silent sinus syndrome” “maxillary atelectasis,” “imploding antrum syndrome,” and “bilateral silent sinus syndrome” was performed. The results were then narrowed to include only relevant articles. Results Relevant articles included three case reports and two articles that describe or mention bilateral SSS. Of the three case reports found, two patients presented with bilateral SSS, whereas the third patient presented metachronously, with the contralateral SSS manifesting 4 months after presentation of the initial ipsilateral SSS. Conclusion The present literature regarding bilateral SSS is likely incomplete, and further investigation is required to provide greater insight into the prevalence of this disease. In this report, bilateral FESS was successful in resolving symptoms and preventing disease progression.

Published: June 2017

Background Chronic idiopathic urticaria (CIU) is a complicated skin disease with unknown pathophysiology. MicroRNAs (miRNA) have been shown to be active in cellular regulation. The goal of this pilot study was to examine whether miRNAs may be involved in the regulation of CIU or as biomarkers for CIU. Methods Four groups of three patients each were selected: patients with either active hives or no hives and with positive or negative chronic urticaria (CU) index results. MiRNAs were isolated from patient plasma and analyzed by using miRNA microarray technology to determine the amount of each of the 2567 known human miRNAs. Results A total of 16 miRNAs were found to be differentially expressed in patients with active hives. Among them, five (2355–3p, 4264, 2355–5p, 29c-5p, and 361–3p) were significantly increased in samples with positive CU index results, which could be useful biomarkers for patients with chronic autoimmune urticaria. The miRNA data bases were used to find the targets of these selected miRNA sequences. These potential targets were then compared against a list of 154 urticaria-related genes. Twenty-five genes were found to match. These included eight that were significantly downregulated and eight that were significantly upregulated; however, seven of the eight downregulated genes (FBXL20, OPHN1, YPEL2, STARD9, EZH1, KLHL24, ING4) and five of the eight upregulated genes (BYSL, PNO1, ADAMTS9, STEAP4, SRGN) have no reported roles in signaling. For the 13 genes with reported roles in signaling, the following pathways were found: transforming growth factor beta signaling pathway (NRC31, KITLG, THBS1, CCL2), glucocorticoid receptor signaling pathway (NR3C1, SELE, CCL2), p53 signaling pathway (CCNG2, THBS1, CCL2), p21-activated kinase pathway (PAK1IP1, KITLG, CCL2), phosphoinositide-3 kinase protein kinase B signaling pathway (KITLG, CHRM, THBS1), and neuroactive ligand-receptor interaction (NRC31, HRH1, CHRM), which could play important roles in CIU. Conclusion A better understanding of those genes with undefined function and simultaneous quantitation of both miRNAs and messenger RNAs are needed to fully understand CIU disease.

Published: June 2017

Background Myxofibrosarcoma (MFS) is a common sarcoma in the extremities of older individuals but is extremely uncommon in the head and neck region. Diagnosis may be challenging but is critical to the management of the patient. We discuss the radiographic and histopathologic characteristics of this destructive tumor. The distinguishing features of MFS and its differential diagnosis are reviewed to familiarize the managing otolaryngologist with this rare entity. Methods A 61-year-old woman presents with a 6-week history of severe left facial pain and left eye pain. Imaging demonstrates significant right and left-sided maxillary sinus opacification with destruction of the left maxillary sinus as well as the left medial and inferior orbital walls. Results Histopathologic examination revealed spindle and stellate tumor cells of variable cellularity in myxoid stroma with cellular pleomorphism consistent with MFS of intermediate-to high grade. The patient underwent resection of the left-sided lesion with orbital exenteration and repair of the defect with microvascular free flap followed by postoperative radiotherapy. Conclusion MFS must be differentiated from other lesions with myxoid qualities. Histopathologic examination is required for definitive diagnosis. Management includes complete tumor excision with adequate tumor margins. Adjuvant postoperative radiotherapy should be considered for larger tumors with positive resection margins or lesions of intermediate-to-high grade.
