Authors: Ahmedova S D 
Published: March 2018

Aim. To conduct epidemiological analysis of the incidence of dermatomycosis (superficial mycoses of skin and its appendages) in the Republic of Azerbaijan during 2000-2016, as well as clinical epidemiological monitoring during 2011-2016.
Methods. Analysis of incidence of visits was performed in the Republican dermato-venerologic clinic, children's republican dermato-venerologic dispansary №3, city dermato-venerologic dispansary №1 of the Republic of Azerbaijan according to the forms of state statistical observation №9 («Information about predominantly sexually transmitted diseases, fungal skin infections and scabies») approved by the decree of Azerbaijan State Statistical Commission No. 72/5 issued on 04.12.2000. Clinical analysis of dermatomycosis incidence during 2011-2016 was performed based on the results of laboratory (microscopic) verification of mycelium of the fungus.
Results. During 2000-2016 in the Republic of Azerbaijan steady increase of the incidence of superficial mycoses of skin and its appendages was observed. In 2000 the incidence was 2783. In 2016, 12 630 cases were recorded, which is the peak value and is 4.5 times higher than in 2000. Clinical analysis of incidence of superficial mycoses of skin and its appendages in 2011-2016 demonstrated that the diagnosis of pityriasis versicolor (keratomycosis) took the leading place (33.5%). The second place in the prevalence was taken by smooth skin mycoses (32.7%), the third place - by candidiasis (skin and visible mucous membranes - 17.1%), the fourth place - by onychomycosis (14.5%), and the last place - by mycosis of the scalp and face (2.2%). Young population (10-20 years) is susceptible to keratomycosis, and adult population (30-50 years) - to smooth skin mycosis. We suggest that it is related to climate-geographic features, increased insolation, and as a result - to sweating and to disordered lipid-alkaline protective skin barrier. To confirm our hypothesis further investigation is necessary.
Conclusion. Incidence of superficial mycoses of skin and its appendages, increased by 4.5 times was revealed; the leading position in prevalence is taken by pityriasis versicolor, the second - by smooth skin mycoses and the third - by skin and visible mucous membranes candidiasis.

Aim. A retrospective analysis of the results of surgical treatment of large idiopathic macular holes depending on the technique of surgical intervention.
Methods. The results of surgical treatment of 60 patients (60 eyes) with idiopathic macular holes with a diameter of more than 800 μm were studied in the Republican clinical ophthalmology hospital of Kazan. The average age of the patients was 66.2±5.37 (61-74) years. The patients underwent complex ophthalmological examination before the surgery and 10 days and 1 month after the surgery, including visometry, tonometry and optical coherence tomography. Patients were divided into two groups (30 subjects each), comparable in clinical and epidemiological parameters: group 1 - standard surgical tactics, group 2 - surgical treatment according to the method proposed by professor A.N. Samoylov. Visual acuity with correction before surgery in group 1 was 0.11±0.05, in group 2 - 0.12±0.06.
Results. Ten days after the surgery, group 1 had anatomical closure in 23 (76.7%) patients, anatomical result was not achieved in 7 (23.3%) patients. In group 2, complete closure of the rupture was achieved in 27 (90.0%) patients, incomplete - in 3 (10.0%) patients. In 1 month in group 1, complete closure of the macular rupture was observed in 22 (73.3%) patients, in 8 (26.7%) patients the result was not achieved. In group 2, complete closure of the rupture was determined in 28 (93.3%) patients, incomplete closure - in 2 (6.7%) patients. Visual acuity 1 month after the surgery in group 1 was 0.15±0.08, and in group 2 - 0.32±0.11 (p <0.05).
Conclusion. Surgical treatment of large idiopathic macular holes according to the modified technique of the inverted internal limiting membrane flap proposed by professor A.N. Samoylov, provides better anatomical and functional results in comparison with the standard technique (p <0.05).

Between Istanbul and Venice: Agency, Faith, and Empire in the Sixteenth Century
Authors: MARTIN John Jeffries 
Published: March 2018

Noel Malcolm’s Agents of Empire: Knights, Corsairs, Jesuits and Spies in the Sixteenth-Century Mediterranean World brilliantly excavates and reconstructs the lives of the members of the Bruni and the Bruti, two prominent Albanian families, whose members played significant roles in the political and military history of the Ottoman and Venetian Empires. This review essay attempts to place this important work in the broader context of Malcolm’s oeuvre and, in particular, to assess the book’s contributions to our understanding of agency, religion, and empire in the early modern period.

Mentor teachers’ feedback role in improving the training of Grades 1-3 student teachers in South Africa
Authors: Hugo Anna Johanna 
Published: March 2018

Mentor teachers play a vital role in the pre-service training of teachers. The role of mentor teachers assumes even more significance when the training is done at a distance education institution. It is impossible for lecturers and university representatives to reach every teacher student during the weeks of teaching practice done at schools in a big country like South Africa. The feedback obtained from the mentor teachers is thus important to train student teachers when they present their lessons during weeks of teaching practice at schools. But the feedback from mentor teachers can also be used for the future training of student teachers. Mentor teachers should, however, also be informed about their role as mentors for student teachers. In this article the way feedback of mentor teachers could be used to improve the quality of the lessons of student teachers when offering language lessons in Grades 1 – 3, is discussed.
A Novel Coreless Injectivity Technique for Evaluating Formation Damage in Argillaceous Reservoirs

Published: March 2018

Abstract
For waterflooding in argillaceous reservoirs, the injection water needs to be carefully designed to avoid formation damage by clay swelling and migration. Common methods of achieving this are compatibility tests of injection water with formation water and rocks and injectivity tests. However, such tests are often not practical nor even possible due to the limited availability and prohibitive cost of obtaining actual reservoir cores. The objective of this work was to develop a cost-effective method to evaluate injectivity that does not require the use of reservoir core. In this study, a novel coreless injectivity method was developed and validated. The method utilizes field-produced drill cuttings to make synthetic core plugs, which are universally available during well drilling and commonly considered as waste. A specially designed cleaning process was performed for the drill cuttings. They were then wet compressed with a high-pressure hydraulic press and dried in a constant-humidity oven to make core plugs with standard dimensions. Drill cutting plugs prepared in this way can then be used for injectivity tests as an alternative to actual reservoir core plugs. The routine core analysis revealed that, although sedimentary structures were lost, the drill cutting plugs preserved the mineralogy and maintained comparable porosity and permeability to the reservoir plugs. To validate the representativeness of the formation damage tendencies of the drill cutting plugs, water injectivity tests were carried out on both preserved reservoir cores and compressed drill cutting cores, using simulated injection water with successively lower salinities. The results showed that injectivity loss as indicated by increasing pressure drop was consistent with both types of cores. The "coreless injectivity evaluation" technique can be applied for argillaceous reservoirs with formation damage concerns. It is a cost-effective and viable technique for evaluating water injectivity when reservoir cores are unavailable.

Published: March 2018

Abstract
The objective of this research was to develop a model to predict the optimum phase behavior of chemical formulations for a given oil based on the molecular structure of the surfactants and co-solvents. The model is sufficiently accurate to provide a useful guide to an experimental testing program for the development of chemical EOR formulations. There are thousands of combinations of surfactants and co-solvents that could be tested for each oil, so even approximate predictions are very useful in terms of reducing the time and effort required for testing and for prioritizing the chemical combinations to test that are most likely to yield ultra-low IFT at reservoir conditions. The effects of changing molecular structures (e.g. swapping head groups, swapping hydrophobes, increasing the length of hydrophobes, increasing the number of PO and EO groups, adjusting the ratios of surfactants) are shown. The variables with the greatest impact on the optimum salinity and solubilization ratio were identified, and methods are proposed to shift the optimum salinity and the optimum solubilization ratios in any desired direction. The structure-property model was developed and tested using a large dataset consisting of 684 microemulsion phase behavior experiments using 24 oils. The chemical formulations used 85 surfactants and 18 co-solvents in various combinations. Both optimum salinity and optimum solubilization ratio (and thus IFT) are modeled whereas other models have focused almost exclusively on the optimum salinity. Predicting the optimum solubilization ratio is actually of more value because of its relationship to IFT. The models include the effects of co-solvent partitioning, soap formation and the molecular structure of both the surfactants and co-solvents.
Comprehensive Review of Worldwide CO2 Immiscible Flooding

Published: March 2018

Abstract
Carbon dioxide (CO2) flooding is a mature technology in oil industry, which finds broad attention in oil production during tertiary oil recovery (EOR). After five decade's developments, there are many successful reports for CO2 miscible flooding. However, operators recognized that achieving miscible phase is one of big challenge in fields with extremely high minimum miscible pressure (MMP) after considering the safety and economics. Compared with CO2 miscible flooding, immiscible CO2 flooding demonstrates the great potentials under varying reservoir/fluid conditions. A comprehensive and high-quality data set for CO2 immiscible flooding are built by collecting various data from books, DOE reports, AAPG database, oil and gas biennially EOR survey, field reports and SPE publications. Important reservoir/fluid information, operational parameters and project performance evaluations are included, which provides the basis for comprehensive data analysis. Combination plot of boxplot and histogram are generated, where boxplots are used to detect the special cases and to summarize the ranges of each parameter; histograms display the distribution of each parameter and to identify the best suitable ranges for propose guidelines.
Results show that CO2 immiscible flooding could recover additional 4.7 to 12.5% of oil with average injection efficiency of 10.07 Mscf/stb; CO2 immiscible technique can be implemented in light/medium/heavy oil reservoirs with a wide range of net thickness (5.2 - 300 ft); yet in heavy oil specifically reservoir (oil gravity &lt;25 °API) with thin layer (net thickness&lt; 50 ft) is better.

Abstract
This paper describes the interpretation of a successful inter-well field trial of a novel reservoir-triggered polymer technology, making use of pressure transient analysis and numerical simulation. The polymer has been engineered to improve sweep in oil-bearing formations whilst reducing the impact of two of the key operational and economic challenges facing polymer enhanced oil recovery (EOR). The polymer employs a chemical strategy to render it resistant to shear during injection and in the high flux region at the sand face. In addition, the injection solution has a viscosity similar to that of water until triggered in the reservoir, which sustains injectivity.
We demonstrate the use of laboratory kinetics, rheology data, high-resolution surveillance of the injector, and comprehensive analysis of produced fluids to constrain the simulation of the in-situ viscosification of this polymer.
Numerical models using commercial and in-house R&D codes were calibrated to tracer effluent data, pressure fall-off tests, and injection pressures, to interpret the size and mobility of the polymer bank and its response to water injection.
The field trial has qualified the polymer to be considered for deployment. A comprehensive surveillance programme and downhole sampling was used to successfully demonstrate that the polymer was protected from shear degradation upon injection and propagation, and it viscosified under flow at the designed location in the reservoir. Kinetic and rheology data from laboratory testing, combined with reservoir-scale simulations and field trial surveillance, enabled the reaction and adsorption characteristics of the polymer to be estimated. Simulations of the injection pressure demonstrate that this polymer has significantly better injectivity under matrix conditions than would be obtained with a conventional polymer of an equivalent deep-reservoir viscosity.

Published: March 2018

Abstract
The relative partitioning of CO2 during and after CO2 injection in a CO2-EOR process is affected by several parameters. While many geological properties cannot be changed in a specific hydrocarbon (HC) reservoir, it could be shown that an intelligent selection of CO2 injection strategy improves both the incremental oil recovery and CO2 storage capacity and security. Therefore, we investigated and discussed the partitioning of CO2 among different phases (oil, gas, and brine) after two well-known CO2 inejction schemes using field-scale compositional reservoir flow modeling in the SACROC (Scurry Area Canyon Reef Operators Committee) unit, Permian Basin. First, we used a high-resolution geocellular model, which was constructed from wireline logs, seismic surveys, core data, and stratigraphic interpretation. As the initial distribution of fluids plays an important role in CO2 partitioning, a comprehensive pressure-production history matching of primary, secondary, and tertiary recovery was completed. The hysteresis model was used to calculate the amount of CO2 trapped as residual. CO2 solubility into brine was verified based on previous experiments. The model results showed a new understanding of relative CO2 partitioning in porous media after a CO2-EOR process. We compared the contribution of CO2 trapping mechanisms and the sweep efficiency of Walter-Alternating-Gas (WAG) and Continous-Gas-Injection (CGI). We found that WAG injection showed a significantly superior behaviour over CGI. WAG not only decreased the amount of mobile CO2 (structural trapping), but also resulted in a competitive incremental oil recovery in comparison with CGI. Thus, clearly WAG injection ispreferred as it strongly enhances CO2 storage efficiency and containment security. The present work provides valuable insights for optimizing oil production and CO2 storage in carbonate reservoirs like SACROC unit. In other words, this work helps decision makers to set storage goals based on optimized project risks.
Gas and Downhole Water Sink-Assisted Gravity Drainage GDWS-AGD EOR Process: Field-Scale Evaluation and Recovery Optimization
Authors: Al-Mudhafar Watheq J. , Wojtanowicz Andrew K. , Rao Dandina N. 
Published: March 2018

Abstract
The Gas and Downhole Water Sink-Assisted Gravity Drainage (GDWS-AGD) process has been developed to overcome of the limitations of Gas flooding processes in reservoir with strong aquifers. These limitations include high levels of water cut and high tendency of water coning. The GDWS-AGD process minimizes the water cut in oil production wells, improve gas injectivity, and further enhance the recovery of bypassed oil, especially in reservoirs with strong water coning tendencies.
The GDWS-AGD process conceptually states installing two 7 inch production casings bi-laterally and completing by two 2-3/8 inch horizontal tubings: oil producer above the oil-water contact (OWC) and one underneath OWC for water sink drainage. The two completions are hydraulically isolated by a packer inside the casing. The water sink completion is produced with a submersible pump that prevents the water from breaking through the oil column and getting into the horizontal oil-producing perforations.
The GDWS-AGD process was evaluated to enhance oil recovery in the heterogeneous upper sandstone pay in South Rumaila Oil field, which has an infinite active aquifer with a huge edge water drive. A compositional reservoir flow model was adopted for the CO2 flooding simulation and optimization of the GDWS-AGD process. Design of Experiments (DoE) and proxy metamodeling were integrated to determine the optimal operational decision parameters that affect the GDWS-AGD process performance: maximum injection rate and pressure in injection wells, maximum oil rate and minimum bottom hole pressure in production wells, and maximum water rates and minimum bottom hole pressure in the water sink wells. More specifically, Latin hypercube sampling and radial basis neural networks were used for the optimization of the GDWS-AGD process performance and to build the proxy model, respectively.
In the GDWS-AGD process results, the water cut and coning tendency were significantly reduced along with the reservoir pressure. That resulted to improve gas injectivity and increase oil recovery. Further improvement in oil recovery was achieved by the DoE optimization after determining the optimal set of operational decision factors that constrains the oil and water production with gas injection. The advantage of GDWS-AGD process comes from its potential feasibility to enhance oil recovery while reducing water coning, water cut, and improving gas injectivity. That gives another privilege for the GDWSAGD process to reach significant improvement in oil recovery in comparison to other gas injection processes, such as the Gas-Assisted Gravity Drainage (GAGD) process, particularly in reservoirs with strong water aquifers.

Abstract
Palogrande-Cebu is a mature clastic field located in the south of Colombia and part of the production train of the Monserrate Formation that has several fields and presents an OOIP about 1000 MMBBLs. In these fields Ecopetrol have been tested different chemical EOR/IOR technologies like polymer flooding, CDG and conformance treatments with encouraging results. Palogrande field has been in production since 1971, and under peripheral water injection since 1984, with a recovery factor of 28%. The reservoir has a permeability between 6 and 150 mD, and a crude with an in-situ viscosity of 9.4 cP at reservoir conditions. As part of a portfolio screening within Ecopetrol, chemical EOR was considered the most viable option for the field. This lead to a polymer flood pilot in Palogrande-Cebu in two patterns from May 2015 to June 2017.
The present paper presents the results of the pilot, which includes the assessment of two different sources of water to prepare the polymeric solution, fresh water and produced water. Likewise, three different polymers were used to assess the impact on injectivity of the molecular weight considering the low permeability of the reservoir. Moreover, the paper presents the data from a comprehensive surveillance and monitoring program, which includes a polymer backflow test to assess the polymer viscosity in the reservoir.
As of June 2017 the accumulated polymer injection was 2.07 million barrels distributed between both injectors, and a projected incremental recovery factor of 8% in the most mature pattern, and 2% in the less mature pattern, with water cut reductions up to 14% in some wells. Based on the success of the pilot, the feasibility of expanding the polymer flood is currently being considered to further develop the field.
