Amaç: Bu
çalışmada, Batman ilinde genç kadın nüfus için önemli bir halk sağlığı sorunu
olan intihar vakalarının sosyodemografik özelliklerini inceleyerek alınabilecek
önlemlere katkıda bulunmayı amaçladık Materyal
ve metot: Batman Bölge Devlet Hastanesi acil servisine, 1 Haziran 2012 - 1 Haziran 2017 tarihleri arasında intihar
girişimi nedeni ile başvuran hastalar retrospektif olarak değerlendirildi. Çalışmaya
alınan hastaların cinsiyeti, yaşı, medeni durumu, okur-yazar olup olmadığı,
intihar yöntemi, hangi mevsim ve saat kaçta gerçekleştirildiği, geçmişte
intihar girişimi öyküsü varlığı, psikiyatri konsültasyonu istemi yapılıp
yapılmadığı, yapılan müdahale ve mortalite oranı incelendi.Bulgular:
Çalışmaya alınan 896 vakanın %83,4’ü
(n=747) kadın, %16,6’ sı (n=149)
erkekti. Yaş dağılımına göre incelediğimizde en fazla başvurunun %57,1
(n=512) ile 15-24 ve takiben %27,2
(n=244) ile 25-34 yaş aralığında olduğunu görüldü. Başvuran kadın vakaların %
49,1’i (n=367) evli, erkeklerin ise %71,8’ i (n=107) bekar idi. tüm vakaların
%58,1’i (n=521) okuma-yazma bilmemekteydi.
İlaç içme %79,5 (n=713) ile en sık karşımıza çıkan intihar sebebi idi.
Toplamda 896 vakanın %8,7’si (n=78) eksitus oldu. Eksitus olan hastaların
%38,4’i (n=30) erkek, %61,5’ü (n=48) kadın idi. Kadınların %47,9’u (n=23) ası
ile eksitus olurken erkeklerde ilk sırada %40 (n=12) ile ateşli silah
yaralanması vardı.

Sonuç: Çalışmamızda 15-24 yaş arası, evli kadınlarda intihar ve intihar
girişim riski yüksek bulunmuştur. Kadınların bu bölgede küçük yaşta yaşlı
insanlar ile evliliğe zorlanması, eğitim düzeyinin düşük olması, aile içi
şiddet, kadınlara uygulanan baskıcı tutum genç kadın nüfusunu intihara
sürüklemektedir. Bu konuda yetkili kurumların gerekli önlemleri almasının
intihar ve intihar girişimlerini azaltmada etkili olabileceği kanaatindeyiz.

Published: March 2018

Patient privacy
is a complex concept that may be affected by many parameters in healthcare
services, especially in Emergency (ER) Departments.

Objective:
To examine the privacy of patients receiving healthcare and medical treatment
in the ED, and to evaluate privacy-related problems, if any, from the ethical
perspective.

Methods: The
data-collecting instrument in this study was a survey form consisting of 11
questions seeking demographic information about participants and 15
privacy-related questions formulated as a 5-point Likert type scale.

Results: The
average age of participants was 42.23±1.716. 220 (96.5%) participants reported
that they did not change the information they provide to physicians and nurses
because such information may be overheard by others. 146 (64.0%) participants agree that paying attention to privacy in the
ER is important. Age is a significant factor in perception of privacy.
Women are more sensitive than men, and married patients are more sensitive than
single patients with regard to privacy.

Conclusions:
Expectations related to the protection of privacy are closely associated with
patients’ trust in physicians. While adhering to the principles of avoiding
delays in treatment, physicians are required to respect patient privacy, with a
view to meeting patient expectations.

Published: March 2018

L’étude porte sur les effets de l’ajout de nano-wollastonite (NW) et de résidus de palmier-dattier sur les propriétés physiques et mécaniques de panneaux de fibres à densité moyenne. Des résines d’urée-formaldéhyde (UF) et d’isocyanate (IC) ont été utilisées à 10 % et 5 %, respectivement, du poids sec du matériau pour produire les panneaux. NW à granulométrie < 100 nm a été utilisé à 5 et 10 % du poids sec des résines, mélangé et pulvérisé sur le matériau avant formation du tapis de fibres. Les résultats ont été ensuite comparés à ceux pour les panneaux sans NW. Ils indiquent clairement une moindre absorption d’humidité et un moindre gonflement en épaisseur pour les panneaux produits avec ajout de résine IC. L’ajout de résidus de palmier-dattier a augmenté significativement les valeurs IB des panneaux produits avec les deux résines, UF et IC. L’ajout de NW a réduit les propriétés mécaniques des panneaux produits avec la résine UF, et amélioré celles des panneaux produits avec la résine IC. En conclusion, les résidus de palmier-dattier peuvent être considérés comme matière première potentielle pour la production de panneaux de fibres à moyenne densité en utilisant les deux résines, UF et IC. D’autre part, l’ajout de NW est recommandé pour la production de panneaux composites avec 10 % de résidus de palmier pour compenser en partie leur moindre résistance mécanique.

Modeling Polymer Enhanced Foam Flow in Porous Media Using An Improved Population-Balance Foam Model

Published: March 2018

Abstract
Higher stability of the bulk and dynamic foam with polymer addition to the aqueous phase has been demonstrated experimentally. Recent experiments indicated that the efficacy of polymer enhanced foam (PEF) is dependent on polymer type and surfactant-polymer interaction. However, numerical modeling of PEF flow in porous media has been relatively less well understood due to the additional complexity. In this work, we propose modifications to the population-balance foam model for PEF modeling, and their successful use in matching the experimental results.
The population-balance model proposed by Chen and co-workers has been used as development platform. Upon reviewing various aspects in the physics of foam generation, coalescence and mobility reduction in porous media with the addition of polymer, a modified population-balance model was proposed with new parameters pertaining to the polymer effect on the net foam generation and the limiting capillary pressure. The new model was implemented and used to history match foam coreflood experiments with and without polymer.
In addition to the foam apparent viscosity increase due to higher viscosity of the aqueous phase, polymer also impacts foamability and foam stability of bulk foam as indicated in the literature. Our modified population-balance model introduce the viscosity terms in foam generation and coalescence coefficients to account for postulated positive impact on reducing liquid drainage and foam coalescence and negative impact on the characteristic time needed for bubble snap-off in porous media. Additionally, a modification in the limiting capillary pressure was proposed in the new model to include the polymer effect based on our analysis of the disjoining pressure. Two new model parameters are proposed and implemented accordingly. The new foam model succeeded in history-matching the anionic-surfactant-based and nonionic-surfactant-based PEF corefloods with different types of polymers through tuning the two new model parameters. The simulations also captured the transient increasing of the pressure drops induced by polymer transport and adsorption. The proposed model can be used to provide meaningful values of the model parameters that were able to explain the physical mechanisms behind the PEF floods and to guide future experimental design to further constraint the choices of model parameters.
This work provided new methodology to model PEF flow in porous media using the mechanistic population-balance approach for the first time. With proper calibrations of the parameters proposed in the model, the new model can therefore be used to simulate PEF EOR processes to describe the combined effect of foam and polymer on the mobility control of the injectants.

Abstract
An integrated enhanced oil recovery (IEOR) approach is presented for fractured oil-wet carbonate reservoirs using surfactant pre-floods to alter wettability, establish conditions for capillary continuity and improve tertiary CO2 foam injections. Surfactant pre-floods, prior to CO2 foam injection, alter the wettability of fracture surface towards weakly water-wet conditions to reduce the capillary threshold pressure for foam generation in matrix and create capillary contact between matrix blocks. The capillary connectivity transmits differential pressure across fractures and increases both mobility control and viscous displacement during CO2 foam injection. Outcrop core plugs were aged to reflect conditions of an ongoing CO2 foam field pilot in West Texas. A range of surfactants were screened for their ability to change wetting state from oil-wet to water-wet. A cationic surfactant was the most effective in shifting the moderately oil-wet cores towards weakly water-wet conditions (from an Amott-Harvey index of - 0.56 ± 0.01 to 0.09 ± 0.02), and was used for pre-floods during IEOR. When applying a surfactant pre-flood in a fractured core system, 32 ± 4% points OOIP was additionally recovered by CO2 foam injection after secondary waterflooding. We argue the enhanced oil recovery is attributed to the surfactant successfully reducing the capillary entry pressure of the oil-wet matrix providing capillary continuity and enhancing volumetric sweep during tertiary CO2 foam injection.
Zone Identification and Oil Saturation Prediction in a Waterflooded Field: Residual Oil Zone, East Seminole Field, Texas, USA, Permian Basin
Authors: Roueché Jacqueline N. , Karacan C. Özgen 
Published: March 2018

Abstract
Recently, the miscible CO2-EOR tertiary process used in the main pay zone (MP) of suitable reservoirs has broadened to include exploitation of the underlying residual oil zone (ROZ) where a significant amount of oil may remain. The objective of this study is to identify the ROZ and to assess the remaining oil in a brownfield ROZ by using core data and conventional well logs with probabilistic and predictive methods.
Core and log data from three wells located in the East Seminole Field in Gaines County, Texas, were used to identify the MP and ROZ in the San Andres Limestone, and to predict oil saturations. The core measurements were used to calculate probabilistic in-situ oil saturations within the MP and the ROZ as a function of depth. Well logs, in combination with core data and calculated saturations, on the other hand, were used to develop two expert systems using artificial neural networks (ANN); one to identify the ROZ and MP, and the other to predict oil saturation. These systems were also supported by a classification and regression tree (CART) analysis to delineate the rules that lead to classifications of zones.
Results showed that expert systems developed and calibrated by combining core and well log data can identify MP and ROZ with a success score of more than 90%. Saturations within these zones can be predicted with a correlation coefficient of around 0.6 for testing and 0.8 for training data. The analyses showed that neutron porosity and density well log readings are the most influential ones to identify zones in this field and to predict oil saturations in the MP and ROZ. To explain the relationships of input data with the results, a rule-based system was also applied, which revealed the underlying petrophysical differences between MP and ROZ.
This new predictive approach using machine learning techniques, could potentially address the challenges that previous studies have come up against in defining the ROZ within the formation and quantifying remaining oil saturations. The method can potentially be applied to additional fields and help reliably identify the ROZ and estimate saturations for future resource evaluations.

Abstract
The main objective of this paper is show the design, implementation and results of a nitrogen + steam pilot implemented in a Colombian heavy oil reservoir. Given that the answer to the cyclic steam injection has declined significantly in some wells of the interest field due to the high number of cycles, a pilot project to assess the feasibility of injecting nitrogen accompanied cyclic steam was raised. The determination of optimum volumes and injection scheme by numerical simulation was performed in a sector model. Eleven schemes of steam plus nitrogen injection were evaluated. In all schemes, it was tested remained constant volume of injected steam, while the volume of nitrogen varied according to the scheme (pre-injection, post-injection, co-injection or a combination of the above). In all cases, it assumed the injection of nitrogen according to real drive capacity 1200 m3/hour (1017072 ft3/day).
The best case corresponds to start injecting only one day with nitrogen, followed by five days of co-injection and ending with a single nitrogen day. Under this scheme an incremental production of 5642 barrels of oil a trial period of six months, with average oil production of 53 BOPD in the same period and maximum rate of 142 BOPD. According to the simulation results, it was decided to implement the pilot steam + nitrogen injection, following the best injection scheme given above; that is, a day of pre-injection (nitrogen only), five days of co-injection (steam + nitrogen) and one day post-injection (nitrogen only). The results of the pilot show that oil production has increased compared to previous cycles, reaching similar results to the numerical simulation forecast. A methodology to implement steam injection enhanced with nitrogen is proposal in this paper, which can be applied in any field of heavy crude scheme developed under cyclic steam stimulation.

Abstract
Injecting low salinity water into a petroleum reservoir to improve oil recovery has been studied extensively over recent years as a low cost enhanced oil recovery (EOR) process. Extensive chemical analyses have been performed on the effluent water from low salinity waterflood experiments which reveal the extent of interaction between the injected brine, the oil and the rock matrix. However, there has been little work reported on the impact of the injected fluid composition on the nature and composition of the oil recovered. This paper details an investigation on how the waterflood medium affects the chemistry of the produced oil, which is important for understanding the mechanism by which the additional oil is released. Produced oil samples were analyzed using High Resolution Mass Spectrometry (HRMS) which essentially measures the mass of individual molecular species very precisely, which makes it possible to assign a unique elemental composition (e.g. carbon, hydrogen, oxygen, nitrogen and sulfur content) to each mass. Additionally, by careful control of the ionization procedure, it was possible to identify acidic and basic polar species, as well as neutral aromatic hydrocarbons. The data indicates that the composition of the produced oil changes during the reduced salinity waterflood, with an increase in the CxHyO2 species occurring. These molecular species, compared to the secondary high salinity flood, are released as the tertiary low salinity injection water passes through the core; they then decline towards the end of the waterflood. In contrast, there appears to be little change in aromaticity, sulfur and nitrogen containing species during the flood. The fact that the produced oil is enriched predominantly with CxHyO2 species is consistent with the multiple ion exchange and local pH rise mechanisms proposed previously.
Reservoir Management of a Low-Salinity Flood on a Per-Pattern Basis

Published: March 2018

Abstract
We use a streamline-based simulator extended to reactive transport with a comprehensive chemical module to model Low Salinity (LS) flooding. To the best of our knowledge, this is the first study to demonstrate the per-pattern management of LS floods. The new reactive transport simulator with LS capabilities allows assessing the incremental oil recovery on a per-pattern basis as a function of water chemistry, mineralogy, moveable oil in place, and geological uncertainty of each injector pattern.
Using a synthetic 3D field example, we show how to quantify the incremental injection efficiency (IIE)—incremental volume of oil produced with respect to standard waterflooding per volume of injected low salinity water—for each pattern. We demonstrate the importance of an uncertainty analysis of cation-exchange capacities and low-salinity oil residual saturations on predicted incremental oil recoveries. Our streamline-based reactive transport approach allows to efficiently explore the dependency of oil recovery on injection water chemistry and reservoir clay mineralogy and provides a unique tool for the management and improvement of LS floods via per-pattern incremental injection efficiencies.
Learning Reservoir Dynamics Metrics of Improved Oil Recovery Projects by Harnessing Real-Time Analysis and Data Analytics

Published: March 2018

Abstract
Real-time analysis and data analytics have become cornerstones in reservoir management of waterflood operations or conformance program. Connectivity between injector-producer pairs and premature breakthrough of injected water or gas are perennial issues that can make or break the economics of secondary and tertiary recovery projects. In this study, we aim to harness the advances in modern data analytics and real-time analysis to systematically evaluate a suite of standard diagnostics tools and propose novel ones for improved recovery projects. Although the scope of these reservoir dynamics evaluation tools can be extensive, our current investigation utilizes data from the Permian Basin.
A suite of reservoir models under varying conditions involving water injection helped understand and evaluate a number of diagnostics tools and devise new characteristics plots. We performed over 8,000 model runs and used data analytics to assess these tools. These tools include water/oil ratio (WOR) vs. time plot, Chan diagnostics, reciprocal-productivity index (RPI) plot, gas/oil ratio (GOR) vs. time plot, among others. We investigated the well-spacing effect ranging from 20 to 320 acres, grid effects, and heterogeneity effects in evaluating these tools. We also explored heterogeneity measures, such as the Dykstra-Parsons method and an index based on final hydrocarbon pore-volume injection (HCPVI), and ultimate recovery. Both cluster analysis and K-means statistics aided this screening process. This study illuminates initial-RPI (IRPI) that has a linear relationship with the ultimate recovery. Cluster analysis of the spread and uncertainty in final recovery vs. IRPI reveals scale invariance. In other words, this diagnostic plot can correctly identify and cluster the spread in final recovery under various well and reservoir quality scenarios, irrespective of the well spacing. Comparison of the final RPI and that at breakthrough with those at initial conditions suggests that IRPI can be a relevant reservoir performance indicator.
This study shows critical parameters for oil recovery under waterflooding are reservoir flow paths and connectivity between layers, reservoir storativity, fluid properties, the thickness of the oil/water transition zone, and fluid mobilities. We also observed that the water breakthrough time does not show a clear relationship with IRPI. Nonetheless, the HCPVI at breakthrough time exhibited a linear correlation with the ultimate oil recovery. In the absence of water production or the presence of water channeling a linear trend emerges for the final HCPVI plot. Cluster analysis and real-time production data analysis have demonstrated the strength of a new reservoir dynamics indicator plot of ultimate hydrocarbon recovery vs. initial reciprocal productivity index. Combination of this indicator and traditional diagnostics and heterogeneity index can quantify the spread of final recovery efficiently.
