Abstract: Gastroesophageal reflux disease affects more than 10% of the adult population. Most patients can be effectively treated with lifestyle changes and adequate acid-reducing therapy. However, about 10% of the patients remain symptomatic despite treatment and severe complications may develop. Interestingly, some of these complications seem to be a sort of defensive mechanism that may either alleviate the patient’s symptoms or prevent developing further complications. In Barrett’s esophagus, which can be unambigously considered as a complication of gastroesophageal reflux disease, reflux symptoms ruining the quality of life may significantly improve, since the metaplastic Barrett epithelium is much more resistent to gastric acid, than the normal epithelial lining of the esophagus. Furthermore, the motility disorders (hypertensive lower esophageal sphincter, achalasia, cricopharyngeal achalasia) and structural changes (Schatzki’s ring, esophageal stricture, subglottic trachea stenosis), which develop as a complication of reflux may help to prevent aspiration that can cause new complaints and may lead to further complications.

Abstract: Introduction: West Nile virus, a mosquito-borne viral zoonosis is responsible for human infections in Hungary. Laboratory diagnosis is based on serological tests, however the application of molecular methods has been appreciated. Aim: The aim of the study was to investigate blood, cerebrospinal-fluid and urine samples of acutely ill patients and to follow-up PCR positive cases to ascertain the length of virus excretion. Method: Clinical specimens were examined by indirect-immunofluorescent, haemagglutination-inhibition, two PCR tests and Sanger-sequencing. Virus isolation in case of two patients was successful. Results: A follow-up study could be carried out in case of 5 patients. Viral nucleic acid was detectable in urine even for several weeks after symptom onset and viral RNA was present at higher concentration compared with other samples. Conclusions: PCR analysis of urine could provide useful epidemiological and diagnostic information. Therefore, it is recommended to collect urine samples in order to supplement the serological diagnosis. Orv Hetil. 2017; 158(20): 791–796.

Published: May 2017

Objectives. To examine whether stricter firearm legislation is associated with rates of fatal police shootings. Methods. We used a cross-sectional, state-level design to evaluate the effect of state-level firearm legislation on rates of fatal police shootings from January 1, 2015, through October 31, 2016. We measured state-level variation in firearm laws with legislative scorecards from the Brady Center, and for fatal police shootings we used The Counted, an online database maintained by The Guardian. Results. State-level firearm legislation was significantly associated with lower rates of fatal police shootings (incidence rate ratio = 0.961; 95% confidence interval = 0.939, 0.984). When we controlled for sociodemographic factors, states in the top quartile of legislative strength had a 51% lower incidence rate than did states in the lowest quartile. Laws aimed at strengthening background checks, promoting safe storage, and reducing gun trafficking were associated with fewer fatal police shootings. Conclusions. Legislative restrictions on firearms are associated with reductions in fatal police shootings. Public Health Implications. Although further research is necessary to determine causality and potential mechanisms, firearm legislation is a potential policy solution for reducing fatal police shootings in the United States.

Design of Injection Facilities for C02 Recovery Process: A Case Study
Authors: Hossain M. 
Published: May 2017

Abstract
Given the impact of CO2 emissions on the environment and the direct correlation to the petroleum industry, it has become evident that our industry must minimize the carbon footprint associated with hydrocarbon production and consumption. One of the obvious choices for utilizing CO2 in the industry is associated with enhanced oil recovery (EOR). The injection of miscible/immiscible CO2 EOR is one of the most attractive techniques in these days for oil industry. As part of this investigation, it is important to assess the source/storage of CO2 to ensure reliability and continuous supply. In addition, it is critical to appropriately design the injection rate of CO2, distribution facilities, and the instrumentation for safe operation.
In this paper, a case study is completed and facilities design are shown as potential sources of CO2 gas handling process. It is also discussed the potential challenges associated with bulk CO2 storage, compression, transportation and injection. Moreover, an evaluation of existing technologies for CO2 handling facilities is conducted to ensure the desired injection fluid specification.
A complete CO2 pipeline network system is developed to determine optimum discharge pressure and design of pipelines specifications is also outlined. The results show that the pump discharge pressure at NGL - CO2 source must be 3,420 psia to meet the 2,850 psia injection wellhead pressure. Also, the ANSI-2500 piping class meets the high injection pressure requirement. In addition, the pipeline network simulation model shows that the optimum pipeline size should be 8 in.
The developed design of Case study CO2 injection facilities is the first CO2 injection project in the company's history. This case study along with its finding will greatly help in controlling the CO2 emission in the environment.
Mechanistic Decline Curves for Gas-Condensate Reservoirs: Model Development
Authors: Ariwibowo R. , Barrufet M. A. 
Published: May 2017

Abstract
This manuscript incorporates material balance, complex fluid behavior, reservoir characteristics, and well operating constraints into a mechanistic model to forecast production from gas-condensate reservoirs. Our model considers condensate banking, while running at least one order magnitude faster than commercial compositional reservoir simulators.
To estimate production from gas-condensate reservoirs we used a thermodynamic cubic equation of state (EOS) to evaluate Constant Volume Depletion (CVD) coupled with radial pseudo-steady state gas flow equations. This allows a relationship between production and time for different production modes (fixed or variable drawdowns, gas rates, or flowing bottomhole pressure), while honoring material balance.
As near-wellbore and reservoir pressure drops below saturation pressure, condensate banking occurs in gas-condensate reservoir causing hindrances to flow. Our model considers the reservoir as two concentric tanks. The conventional CVD is modified to begin production at pressures higher than the saturation pressure and to allow two-phase flow. The inner small CVD tank is used to model the near-wellbore saturation using alternative production rules and ‘replenishment’ schemes. The saturation determined from the small tank determines the appropriate relative permeabilities in the flow equation.
The forecasts developed from this mechanistic model versus conventional decline curves, constructed from a commercial numerical simulator predicted data, show very promising results and stress the danger of using empirical methods.
The value of this model rests in its portability, speed and flexibility, while using rigorous mass balance, complex two-phase flow behavior, and realistic production constraints. This method provides the physical basis for reservoir engineers to predict a more reliable production behavior from gas-condensate reservoirs that can be used to plan depletion strategies and facilities.
A Production Characterization of the Eagle Ford Shale, Texas - A Bayesian Analysis Approach

Published: May 2017

Abstract
We began this research by asking "Can we use Bayes' theorem to supplement available decline models and improve the accuracy of our estimates of ultimate recovery?" This study focuses on the Eagle Ford Shale, and in particular, on oil wells in the Greater Core Eagle Ford Area. Our goal was to develop a method based on a probabilistic approach to identify, characterize, and better model well production based on standard decline models
To attempt to answer this question, we first obtained data for 68 wells in the Greater Core of the Eagle Ford Shale, Texas. As process, we eliminated the wells that did not have enough production data, wells that did not show a production decline and wells that had too much data noise, leaving eight wells. We then performed decline curve analysis (DCA) using the Modified Hyperbolic (MH) and Power-Law Exponential (PLE) models (the two most common DCA models), consisting in user-guided analysis software. Then, the Bayesian paradigm was implemented to calibrate the same two models on the same set of wells.
The primary focus of the research was the implementation of the Bayesian paradigm on the eight-well data set. We first performed a "best fit" parameter estimation using least squares optimization, which provided an optimized set of parameters for the two decline models. This was followed by using the Markov Chain Monte Carlo (MCMC) integration of the Bayesian posterior function for each model, which provided a full probabilistic description of its parameters. This allowed for the simulation of a number of likely realizations of the decline curves, from which first order statistics were computed to provide a confidence metric on the calibration of each model as applied to the production data of each well.
Results showed variation on the calibration of the MH and PLE models. The forward models (MH and PLE) overestimated the ultimate recovery in the majority of the wells compared with the Bayesian calibrations, proving that the Bayesian paradigm was able to capture a more accurate trend of the data and thus able to determine more accurate estimates of reserves.
In industry, the same decline models are used for unconventional wells as for conventional wells, even though we know that the same models may not apply. Based on the proposed results, we believe that Bayesian inference yields more accurate estimates of ultimate recovery for unconventional reservoirs than deterministic DCA methods. Moreover, it provides a measure of confidence on the prediction of production as a function of varying data and varying decline models.
3D Modeling of Carbonate Rock Porous Media and Estimation of Petrophysical Parameters

Published: May 2017

Abstract
Pre-salt carbonate reservoirs are known by their huge heterogeneity and their porous system present a challenge regarding reservoir characterization, petrophysical parameters analysis and full understanding of fluid flow dynamics. Besides that, the cost of obtaining rock samples from the reservoir and the destructive nature of most experimental tests increase the interest in develop the concept of Digital Rock Physics (DRP); DRP is based on high resolution imaging and three-dimensional digitizing aiming to investigate and calculate the physical and fluid flow properties of the porous media. In this approach, this work uses X-Ray computed microtomography, digital reconstruction and image processing to achieve the 3D modeling of porous media and estimate petrophysical parameters of Pre-Salt lacustrine carbonate analog samples: coquinas from Morro do Chaves Formation, Northeast Brazil. Experimental data is used to validate the predictions. The results suggest that an important step in the rock digital reconstruction refers to the segmentation process and the high computational cost is a limiting factor to generate the porous media model in three dimensions. Despite this, the estimated physical properties are in good agreement with the previous measured experimental values and the generated 3D model will be widely used in numerical flow simulations in the next steps of this study.
