Rock Typing in Eagle Ford, Barnett, and Woodford Formations
Authors: Gupta Ishank , Rai Chandra , Sondergeld Carl , Devegowda Deepak 
Published: March 2018

SummaryShales are the most commonly found sedimentary rocks on Earth. Most US shale plays are massive, with different maturity regions and varying prospects. There has been a paradigm shift in the understanding of shale anisotropy and microstructures in the last decade, with a high focus on the identification of sweet spots and optimal reservoir-quality zones. Rock typing is one of the sought-after techniques to achieve this objective, and it has become an integrated part of the unconventional-characterization work flow.In this work, rock typing was performed with an integrated work flow using laboratory petrophysical measurements. The rock types were derived with machine-learning clustering algorithms—namely, K-means and self-organizing maps (SOM). The integrated work flow was applied in three different shale plays: Eagle Ford, Barnett, and Woodford.Three different rock types were identified. In general, Rock Type 1 had the highest porosity and total organic carbon (TOC), indicative of highest storage and source-rock potential, respectively. Rock Type 1 was also the key rock type controlling the production. Rock Type 2 had intermediate porosity and TOC, whereas Rock Type 3 had the lowest porosity and TOC.Next, core-derived rock types had to be scaled up to logs. Support vector machines (SVM), a classification algorithm, was used for scaling up. It was trained with a data set consisting of depths at which both core and log data were available. Different logs such as gamma ray, resistivity, neutron, and density were used for scaling up. Finally, a rock-type ratio (RTR) was defined from rock-type logs based on fraction of Rock Type 1 over gross thickness. The ratio thus developed was found to have a strong correlation with normalized oil-equivalent production rate.In total, 22 wells with core data were considered for rock typing in the three shale plays. The rock types were scaled up to 95 wells at a cumulative over a 20,000-ft depth interval. The work flow shown in this paper can easily be extended to other data sets in other plays. The manual approach, on the other hand, can be prohibitively time-consuming.
Extension of Dykstra-Parsons Model of Stratified-Reservoir Waterflood To Include Advanced Well Completions
Authors: Muradov K.. , Prakasa B.. , Davies D.. 
Published: March 2018

Summary
Large volumes of oil are being produced by waterflooding heterogeneous reservoirs. Careful flood-pattern design, well placement, and control are required to maximize oil recovery by delaying water breakthrough and optimizing sweep efficiency. Models that analyze the waterflood's performance and predict the production forecast, such as the Dykstra-Parsons (DP) method, are routinely used for this purpose.
The DP method estimates the vertical-flooding efficiency between conventional wells producing from noncommunicating layers. This method and its various modifications have had a significant impact on the development of the theoretical description of the waterflooding process. The DP method is still routinely used for waterflood-performance prediction and analysis, flood-pattern selection, and recovery-factor calculation.
Advanced well completions (AWCs) control the fluid flow at the reservoir sandface. They have become a proven, widely used technology (particularly in waterflooded reservoirs) for modifying a production or injection well's inflow/outflow rate profile along the well. In addition to this, new AWC designs that react to water breakthrough have recently become available. Incorporating a description of the AWC performance into the waterflood-analysis models will allow fast forecasting of the production profile and oil recovery, as well as help in optimizing the AWC configuration and control at the well-design stage.
This work extends the DP method for rapid prediction of the waterflood's performance to AWC wells. It provides a simple means of estimating the additional, long-term value derived by controlling zonal flow rate using AWCs or any other means (e.g., well workover). The accuracy of the extended DP method's prediction has been verified by comparison against the results from a numerical reservoir simulator. Several examples illustrate the extended DP model's performance and value. The method's limitations and possible future extensions are also discussed.
The presented model is a simple, transparent approach to evaluating the impact on the waterflood's oil recovery efficiency (RE) of various well-completion and control options. It can be implemented as an analytical model or as a fast simulator. This model is also the missing link between the various AWC design methods available today and the AWCs' long-term value evaluation.
Advancing the MPD Influx Management Envelope IME: A Comprehensive Approach to Assess the Factors that Affect the Shape of the IME
Authors: Patil Harshad , Ponder Terry Lamar , Arnone Maurizio , Hannegan Don 
Published: March 2018

Abstract
With increasing utilization of Managed Pressure Drilling (MPD), the industry today is leaning heavily towards the use of improved safety aspects that MPD systems exhibit. With the technological advancements to detect influxes, some of today's MPD systems are equipped with algorithms to automatically apply surface backpressure (SBP) in order to restore the overbalance while retaining the ability to circulate the small volumes of formation fluids (influx) that entered the wellbore prior to achieving the overbalance. Even when conventional well control (shutting well on BOP and circulating the kick out conventionally with the rig's choke) is used, the effectiveness of circulating a small influx using the automated MPD choke is a significant advancement for the drilling industry overall.
Some MPD systems used today have the capacity to prevent shut-in scenarios by automating the influx- handling process. The influx management envelope (IME) or MPD matrix traditionally defines the limits within which the MPD system could potentially be safely used to control and circulate these small influxes. This paper primarily proposes advancing the methodology to define the shape and size of the MPD IME defined in SPE 170684 (Mehdi 2014). It explains the changes in the shape of the IME using appropriate examples, for the various limiting factors, such as, "shoe strengths lower than RCD (Rotating Control Device) limit," "shut in scenario during circulating influx," "maximum flow rate for circulation," "mud compressibility with added backpressure," "Mud gas separator (MGS) liquid and gas handling capacity" etc. The modified shape of the resulting MPD IME is discussed systematically in this paper.

Authors: Sohrab Sayed Sartaj , El-Kafrawy Sherif Aly , Mirza Zeenat , Kamal Mohammad Amjad , Azhar Esam Ibraheem 
Published: March 2018

Background:
The MERS-CoV is a novel human coronavirus causing respiratory syndrome since April
2012. The replication of MERS-CoV is mediated by ORF 1ab and viral gene activity can be modulated by RNAi
approach. The inhibition of virus replication has been documented in cell culture against multiple viruses by
RNAi approach. Currently, very few siRNA against MERS-CoV have been computationally designed and published.

Methods:
In this review, we have discussed the computational designing and delivery of potential siRNAs. Potential
siRNA can be designed to silence a desired gene by considering many factors like target site, specificity,
length and nucleotide content of siRNA, removal of potential off-target sites, toxicity and immunogenic responses.
The efficient delivery of siRNAs into targeted cells faces many challenges like enzymatic degradation and
quick clearance through renal system. The siRNA can be delivered using transfection, electroporation and viral
gene transfer. Currently, siRNAs delivery has been improved by using advanced nanotechnology like lipid nanoparticles,
inorganic nanoparticles and polymeric nanoparticles.

Conclusion:
The efficacy of siRNA-based therapeutics has been used not only against many viral diseases but
also against non-viral diseases, cancer, dominant genetic disorders, and autoimmune disease. This innovative
technology has attracted researchers, academia and pharmaceuticals industries towards designing and development
of highly effective and targeted disease therapy. By using this technology, effective and potential siRNAs
can be designed, delivered and their efficacy with toxic effects and immunogenic responses can be tested against
MERS-CoV.
Discrepancies in assessing undergraduates’ pragmatics learning
Authors: Ndayizeye Oscar 
Published: March 2018

The purpose of this research was to reveal the level of implementation of authentic assessment in the pragmatics course at the English Education Department of a university. Discrepancy Evaluation Model (DEM) was used. The instruments were questionnaire, documentation, and observation. The result of the research shows that respectively, the effectiveness of definition, installation, process, and production stages in logits are -0.06, -0.14, 0.45, and 0.02 on its aspect of the assessment methods’ effectiveness in uncovering students’ ability. Such values indicate that the level of implementation fell respectively into ‘very high’,’high’, ‘low’, and ‘very low’ categories. The students’ success rate is in ‘very high’ category with the average score of 3.22. However, the overall implementation of the authentic assessment fell into a ‘low’ category with the average score of 0.06. Discrepancies leading to such a low implementation are the unavailability of the assessment scheme, that of scoring rubric, minimal (only 54.54%) diversification of assessment methods, infrequency of the lecturer’s feedback on the students’ academic achievement, and the non-use of portfolio assessment.

The Mesoscale Convective Systems with bow echo radar signatures as an example of extremely severe and widespread geohazard in Poland
Authors: Widawski Artur , Pilorz Wojciech 
Published: March 2018

Abstract
In the last two decades we can notice a significant increase of severe anemological events, which are mostly connected with mesoscale convective systems and a cold front of a deep low-pressure system. One of them are very strong winds with speeds more than 25 m/s. They caused material damage and threatening people's lives. The most dangerous are winds generated by mesoscale convective systems where radar reflectivity signatures of bow echo/derecho appeared. In this paper the area of occurrence of such phenomenon in Poland are described and the features of bow echo signatures on radar images are presented and explained. Additionally one of the most severe event and still very weakly known episode of 11th August 2017 derecho in Poland is analysed. The damage data from European Severe Weather Database (ESWD) were analysed to confirm if the August 11th storm met derecho criteria. To identify the radar reflectivity signatures inside MCC the data from the Polish Institute of Meteorology and Water Management shared on the radar-opadow.pl site were used. The CAPPI 1 km data were very useful to determine the convective forms. After that the data from synoptic station were examined for presenting the running of selected meteorological elements. Finally, some information about material damage in infrastructures and forests are mentioned.
Gender and economic orientation as correlates of attitudes towards environmental abuse: A study of a group of Nigerian undergraduates
Authors: Ibrahim Fausat M. , Ibrahim Bashirat A. 
Published: March 2018

Abstract
Equity is central to concerns over environmental sustainability. Gender and economic power constitute prime bases of inequalities in human society. Moreover, university education has the potential to produce ideal individuals equipped to advance noble causes including environmental sanity. Hence, this study was designed to examine how economic and gender orientation affects attitude towards environmental abuse among a group of Nigerian undergraduates. Structured questionnaire were self-administered to 1120 randomly selected respondents and 1098 were analyzed. Multi-item measures were used to assess variables. One way ANOVA, Brown-Forsythe's test and Spearman's correlation r were used to analyze data. Results show that the mean score for attitudes towards environmental abuse was high (5.38±0.87, min. = 1.0, max. = 7.0) but, the generic pattern for attitude was fairly environmentally friendly because only 56.7% of respondents scored the mean or above. Age, sex and marital status had no effect on their attitude (p > 0.05) but religion and field of study did (p < 0.05). Economic and gender orientations were significantly and positively related to attitude towards environmental abuse (p < 0.05). Being Muslim and Christian as opposed to being a practitioner of a traditional religion; and undertaking studies within the field of biology and life sciences as well as science and technology, as opposed to social sciences, humanities and arts, predisposes students to healthier attitudes towards environmental abuse. Collectivist economic orientation and egalitarian gender orientation predisposes students to a healthier attitude towards environmental abuse.
Aplication of IDW and RBF methods to develop models of temperature distribution within a spoil tip located in Wojkowice, Poland
Authors: Zarychta Adrian , Zarychta Roksana 
Published: March 2018

Abstract
This article describes two methods of showing the distribution of temperature on the surface and inside a spoil tip (coal mine waste dump) located in Wojkowice (in the Silesian Voivodeship). Two deterministic estimation methods were tested, i.e., Inverse Distance Weighting (IDW) and Radial Basis Functions (RBF). According to isotherm maps the highest temperature on the surface of the “Wojkowice” spoil tip was in the NE area, while inside the heap the highest temperature noted was in the SW area. Better results were obtained from the application of the RBF method. A three-dimensional model (3D model) was generated by the method, which visualized the temperature distribution within the “Wojkowice” spoil tip. According to the 3D model of the temperature distribution the greatest heat centre inside the heap in Wojkowice was located in the SW part with a temperature of around 300°C. As a result, it can be concluded that the material of the “Wojkowice” spoil tip is burning out in a NW direction. On the basis of the model obtained it is possible to determine the location of potentially dangerous places which are exposed to possible deformations caused by the material burning under the surface. The results of the research presented make it possible to assess the thermal state of the spoil heap located in Wojkowice, Poland.
Land accessibility constraints of migrants in rural border settlements of Ogun State, Nigeria

Published: March 2018

Abstract
The study examined land accessibility constraints among migrants in rural border settlements of Ogun State, Nigeria. It specifically examined dimensions, extent of importance of the constraints and their joint interactive influence on land accessibility. Data were collected through questionnaires on migrant household heads. A multi-stage sampling technique was used for the selection of 492 respondents for the study. Data collected were analysed using descriptive and inferential statistics (t-test, relative important index (RII) and correlation statistics). The study revealed that the majority of the sampled migrants were within an active and productive population (31-60 years). Also, the larger percentage of the respondents were male (64.8%), married (70%), farmers (67.2%) with no formal education (51.3%). Most of the migrants have stayed above 6 years (79.8%) in the study area. This is an indication that migrants would have detailed experience about their land accessibility constraints. Findings showed that the high cost of land was the major constraint to land accessibility and non-availability of land (scarcity) was the least constraint. The study further revealed that the high cost of land, inability to transfer land, difficulty in land transaction and insecure tenure jointly influenced migrants' access to land in the study area. The study therefore recommended the need for an efficient land administration and governance at local government level in order to accommodate the attendant needs of rural migrants in the study area.
