Abstract: The activity concentrations of 238U, 232Th and 40K have been determined for solid, liquid and product (urea) samples collected from the Chittagong Urea Fertilizer Limited (CUFL), Chittagong, Bangladesh. A total of 15 samples of different kinds were analyzed by using a calibrated high purity germanium (HpGe) detector of relative efficiency of 38%. For solid samples, the mean activity concentrations of 238U, 232Th and 40K have been found 78.67±2.87, 59.74±2.27 and 463.71±9.16 Bq/Kg, respectively. The mean activity concentrations of product samples for the corresponding radionuclide were 73.12±2.83, 74.59±2.32 and 391.58±9.38 Bq/Kg, respectively. For the case of liquid samples, the mean activity concentrations for the same nuclides were 25.09±1.71, 11.34±1.55 and 39.59±1.49 Bq/Kg, respectively. The artificial radionuclide 137Cs was not detected in any of the samples. The mean radiological hazard parameter values of outdoor absorbed dose rate, indoor absorbed dose rate, external radiation hazard, internal radiation hazard, annual effective dose equivalent, radium equivalent activity and representative level index were 95.72±9.04, 114.32±9.11 nGyh-1, 0.530±.05, 0.7±50.05, 113.59±11.41μSvy-1, 199.80±17.41 and 1.390±.14 Bq/Kg respectively, in solid samples. For the product samples, the mean values of the corresponding radiological indices were 97.10+9.71, 117.56+10.32 nGyh-1, 0.57±0.05 , 0.76±0.06, 119.50 ±11.72μSvy-1 , 209.50±17.72 and 1.50±0.14 Bq/Kg, respectively. Also in the liquid samples, the mean values for the corresponding radiological parameters were 18.43±2.69, 22.13±2.77 nGy.h−1, 0.12±0.03 , 0.19±0.05, 23.59± 2.36 μSvy1, 43.65±3.54 and 0.32±0.03 Bq/Kg, respectively. The obtained results of this study show that for some samples the values are lower and for the remaining are higher than the World average values. The mean representative index value is less than unity which confirms that the area is safe for the factory workers and the public nearby. The results can be used as a baseline data for further researchers.

The effectiveness of a disinfectant-based decolonization strategy for multidrug-resistant bacteria like extended spectrum β-lactamase (ESBL)-positive Gram-negative bacteria with or without additional fluoroquinolon and carbapenem resistance as well as vancomycin-resistant enterococci and methicillin-resistant Staphylococcus aureus was assessed.
Between 2011 and 2015, 25 patients from Libya, Syria, and the Ukraine with war traumata were treated at the Bundeswehr hospital Hamburg. The patients were heavily colonized and infected with multidrug-resistant bacteria, altogether comprising 371 distinct combinations of pathogens and isolation sites. Local disinfection was assessed for effectiveness regarding successful decolonization of multidrug-resistant bacteria.
Altogether, 170 cases of successful decolonization were observed, comprising 95 (55.8%) such events at sampling sites that were accessible to disinfecting procedures. The remaining 75 (44.2%) decolonization events had to be considered as spontaneous. In contrast, 95 out of 172 (55.2%) colonized isolation sites that were accessible to disinfection procedures were successfully decolonized. Patient compliance with the enforced hygiene procedures was associated with decolonization success. Systemic antibiotic therapy did not relevantly affect isolation time.
Disinfecting washing moderately supports local decolonization of multidrug-resistant pathogens in comparison with spontaneous decolonization rates if the patients’ compliance with the applied hygiene procedures is ensured.

Published: June 2017

Abstract
Today's economic conditions emphasize the need for better engineering designs in drilling, well completion, and reservoir production operations. A knowledge of the mechanical behavior of reservoir rocks is important in connection with wellbore stability problems, fracturing operations, subsidence problems and sand production problems. To carry out any aforementioned operations, continuous profiles of rock mechanical parameters are needed. Retrieving reservoir rock samples throughout the depth of the reservoir section and performing laboratory tests on them are extremely expensive as well as time consuming.
Consequently, rock failure parameters are often correlated with geophysical well logs such as bulk density, compressional and shear wave velocities, which may result in continuous profiles of failure parameters throughout the depth of the well section. However, these estimations not truly represent the reservoir in-situ stress-strain condition. Therefore, failure parameters are estimated from empirical correlations.
Most of the previous correlations were developed using linear or non-linear regression techniques. Artificial intelligence tools once optimized for training can successfully model highly complex and nonlinear relationship between different well logs as inputs and failure parameters as output. Therefore, the objective of this paper is to accurately predict the failure parameters (Angle of internal friction and Cohesion) of the rock by using basic geophysical well logs namely; bulk density, neutron porosity, compressional, and shear wave travel times, from three artificial intelligence techniques namely; Adaptive Neuro Fuzzy Inference System (ANFIS), Support Vector Machine (SVM) and Functional Network (FN).
The data used in this study were obtained from more than 10 wells located in giant carbonate reservoir. A comparison between the predicted failure parameters by the proposed models with actual laboratory measured data reveals that new proposed model predicted with significantly less average absolute percentage error (AAPE) and high coefficient of determination (R2).
The developed technique can be useful for geo-mechanical engineers to determine continuous failure parameters profiles throughout the desired depth, when no laboratory tests are available.
An Anomalous Productivity Model for Naturally Fractured Shale Gas Reservoirs
Authors: David Obembe Abiola , Hasan Muhammad , Fraim Michael 
Published: June 2017

Abstract
Numerous mathematical models have been proposed to describe the complex nature of gas transport in naturally fractured, Nano-porous shale gas reservoirs (NNSGR's). However, a critical assessment of the literature reveals that the anomalous nature of gas transport in these systems are not adequately captured in those mathematical models. To this end, we extend the transient linear double porosity (DP) model established in the literature for scenarios where the underlying diffusion in the stimulated reservoir volume (SRV) is non-classical (i.e. anomalous). Furthermore, the contribution of gas desorption, and its subsequent diffusion to the fracture network in the SVR is considered.
The mathematical model developed describes gas transport into a horizontal well located in the center of a closed rectangular NNSGR by employing a time fractional flux relationship, the classic continuity equation, a transient interporosity source term between both overlapping media, as well as the multilayer BET adsorption model. The time fractional flux relationship portrays a power law decay trend as compared to the exponential decay trend demonstrated in the Darcy-based mathematical models. The Laplace transform method is utilized to handle the resulting mathematical model to obtain semianalytical expressions for the dimensionless flowrate and cumulative gas production at the wellbore for a constant flowing pressure inner boundary condition at the producer well. Subsequently, qualitative and quantitative validation of these outputs with existing models in literature are investigated.
The developed model converges to the established DP model, for the very limiting case when the diffusion behavior approaches Darcy type flux. The sensitivity of the diffusion exponent and phenomenological coefficients in the SRV were analyzed. Of great significance, the parametric study demonstrates that the developed transient anomalous linear dual porosity (ADP) model proffers the reservoir engineer more flexibility to capture the complexities and the power law trend observed in these complex systems in the field.
The mathematical model presented in this study will find wide spread applications in predicting the performance of horizontal wells producing in NNSGR's where analog studies reveal high spacing aspect ratio in the reservoir.
A Comparative Study of Proxy Modeling Techniques in Assisted History Matching

Published: June 2017

Abstract
Assisted history matching approach has been arisen in the last few decades in an attempt to make the process of history matching faster and easier. Assisted history matching simply involves converting the history matching problem to an optimization problem. One main aspect of the assisted history matching is building proxy model that interpolates the relationship between the objective function and the history matching parameters. Several proxy modeling techniques are introduced in the literature, some are useful and some are not.
This paper provides a comparative study between four powerful proxy modeling techniques in assisted history matching; Thin Plate Spline, Radial Basis Function, Kriging, and Artificial Neural Network. Two test problems of different reservoir engineering approaches (material balance and reservoir simulation) are used to test and compare the performance of the studied proxy methods on solving assisted history matching problems. To make the comparison reliable, a performance indicator is developed to compare between the four studied techniques. The performance indicator represents the relative error between the estimated values of history matching parameters calculated using the studied proxy modeling methods and their exact solutions.
The results of this work indicate that the Kriging and artificial neural network proxy techniques are more efficient and superior to thin plate spline and radial basis function.
Sobol and Halton Sequences: Efficient Experimental Design Techniques towards Improved Uncertainty Quantification of Petroleum Reservoirs

Published: June 2017

Abstract
Reservoir simulation models often suffer from significant uncertainties due to the lack and inaccuracies of the measured data. Hence, uncertainty analysis and quantification are considered as major concerns in building robust and predictive simulation models. The conventional approach of the uncertainty analysis is conducted by running a very large number of simulation runs in an attempt to capture all effects of the uncertain parameters. Running a large number of simulation runs is costly and very time consuming and therefore efficient approaches have been arisen. One of these efficient approaches is the Experimental Design technique. The experimental design technique is widely applied in different engineering practices for assessing and quantifying uncertainties. Experimental design is the technique used to guide the selection of the samples within the design search space of the uncertain parameters in order to obtain the maximum amount of information using low number of experiments. Several experimental design techniques are applied in petroleum industry and specially in reservoir simulation assisted history matching. Some experimental design techniques shows more effectiveness than others.
The objective of this paper is to introduce two efficient experimental design techniques (Halton and Sobol sequences) to the reservoir simulation assisted history matching workflow. This work is to complete the work done by the authors and published in Shams et al. (2017). Shams et al. (2017) applied and tested the potentiality of the two proposed experimental design techniques through a comparative study between their performance in solving assisted history matching problems of different scale material balance problems and the performance of the most widely used experimental design technique, Latin hypercube. In this paper the comparative study is conducted using numerical reservoir simulation model. A performance indicator is developed to compare between the three studied techniques. The performance indicator represents the relative error between the estimated values of history matching parameters calculated using the studied experimental design methods and their exact solutions.
The results of this work validate the previous obtained conclusions and indicate that the Sobol and Halton sequences experimental design techniques are more efficient and superior to Latin hypercube method.
A Mathematical Model for Transient Testing of Naturally Fractured Shale Gas Reservoirs
Authors: Obembe Abiola David , Hasan Muhammad , Fraim Michael 
Published: June 2017

Abstract
Transient linear triple porosity diffusion models (TPM) have been developed to justify the unexpected high gas production observed in naturally fractured, nanoporous shale gas reservoirs (NNSGR's). However, a critical assessment of the predictive capabilities of these models reveal that if the presence of obstacles, disconnected pathways in the matrix, and/or poor fracture connectivity in the fracture-matrix system are to be considered, these models may be inappropriate to describe the gas transport mechanisms in these complex systems. To overcome these limitations, an anomalous triple porosity model (ATPM) is developed to describe the gas production from a horizontal well producing in a NNSGR, allowing for the possibility of sub-diffusion in the matrix and micro-fracture within the stimulated reservoir volume (SRV).
The mathematical model entails the use of a modified constitutive flux relationship for the flow behavior in the matrix, micro and macro-fractures rather than the empirical Darcy's equation. The Laplace transform method is employed to handle the resulting mathematical model to obtain semi-analytical expressions for the dimensionless matrix pressure, micro fracture pressure, macro fracture pressure, and wellbore flowrate. subsequently, qualitative and quantitative validation of the rate-transient at the wellbore against existing solutions in literature are demonstrated.
The ATPM solution converges to both the transient linear double porosity diffusion mathematical model (DPM) and the sequential TPM solutions established in the literature under very limiting conditions. The sensitivity of the introduced parameters was analyzed and presented through numerically generated type curves. Parametric study suggests that the derived ATPM solution exhibits unique behaviors and trends not observed in the previous mathematical models. Furthermore, the parametric study reveals the magnitude of the diffusion exponent affects the slope of the straight line observed in the log-log plot of rate and time.
The advantage of the ATPM is that detailed information of the matrix, micro fracture and macro fracture petrophysical properties can be modeled as compared to the TPM. Furthermore, this model may find wide spread application for predicting the performance of horizontal wells producing in NNSGR's where analog studies reveal low spacing aspect ratio in the reservoir.

Abstract
Super critical carbon dioxide (SC-CO2) flooding is one of the most important enhanced oil recovery (EOR) methods to recover oil from both sandstone and carbonate reservoirs. In many cases this process is handicapped, especially in thick reservoirs, by SC-CO2 gravity override. SC-CO2 is lighter than oil and water, so there can be extensive gravity override of SC-CO2 bypassing oil in the lower part of the formation. Different methods have been used to control SC-CO2 mobility and improve its sweep efficiency by either increasing its density, viscosity, or reducing its relative permeability. SC-CO2 as a foam or as an emulsion is one of these methods and can provide better mobility control of the injected SC-CO2. This paper investigates the impact of various parameters such as liquid/liquid ratio, different foam qualities and different injection modes on the SC-CO2-foam quality and its rheological properties.
In this study, types of surfactants were used to generate SC-CO2-foam. SC-CO2-foam was generated at two different type of injection modes. Experiments were designed and conducted in a high pressure and temperature flow loop instrument to identify the optimum surfactant concentration and liquid/liquid ratio that can produce high quality foam and increase the SC-CO2 viscosity. During the experiment, SC-CO2-foam characteristics were analyzed through a visual cell in terms of bubble size distribution.
The rheological properties of the SC-CO2-foam were investigated by varying the shear rate, shear stress, foam quality, injection modes and foaming agent concentrations at reservoir conditions. The experimental results show that the foam mobility (total mobility of SC-CO2-surfactant solution) decreases with increasing foam quality. The results indicate that the SC-CO2-foam can make strong and stable foams under certain conditions. This was also correlated with the images of the high pressure, high temperature (HPHT) foams that were captured through microscope at different time intervals and analyzed to indicate their stability. Two foaming agents were identified that show excellent foam quality with good foam strength and stability over a period of time at reservoir conditions.
