Probabilistically Mapping Well Performance in Unconventional Reservoirs with a Physics-Based Decline-Curve Model
Authors: de Holanda Rafael Wanderley , Gildin Eduardo , Valkó Peter P. 
Published: April 2019

Summary
Decline curves are the simplest type of model to use to forecast production from oil and gas reservoirs. Using a selected decline model and observed production data, a trend is projected to predict future well performance and reserves. Despite capturing general trends, these models are not sufficient at describing the underlying physics of complex multiphase porous-media flow phenomena and at explaining variations in production caused by changes in operational conditions. The application of these models within a Bayesian framework is a feasible alternative to mitigate this issue and obtain more-robust forecasts by representing the possible outcomes with probability distributions. However, one important aspect that conditions the production forecasts and their uncertainty is the design of a suitable prior distribution, which can be subjective.
To address the aforementioned issue, this paper presents a workflow for the development of a localized prior distribution for new wells drilled in shale formations that combines production data from pre-existing surrounding wells and spatial data, specifically well-surface/bottom coordinates. This workflow aims to establish engineering criteria to reduce the subjectivity in the design of a prior distribution, assessing spatial continuity of the parameters of a physics-based decline-curve model (θ2 model), automatically identifying regions where uncertainty can be reduced a priori, and reliably quantifying the uncertainty.
A case study of 814 gas wells in the Barnett Shale is presented, and several maps are generated for the analysis of important properties to be considered during field development. The dry-gas window presented more-continuous decline-curve parameters than the wet-gas and gas/condensate windows, which resulted in lower uncertainty with the localized prior approach. As more data are acquired with time, the uncertainty in the production forecasts is further reduced and the localized prior becomes more informative, especially in the dry-gas window. The localized prior can then serve as an indicator for the performance of new infill wells in different locations.

Abstract
The interaction between Fusarium oxysporum f. sp. vasinfectum (Fov) and Meloidogyne incognita (root-knot nematode) resulting in Fusarium wilt (FW) of cotton is well-known. Although Belonolaimus longicaudatus (sting nematode) can also interact with Fov and cause FW, it has long been believed that virtually all of the FW in Georgia is caused by the interaction of Fov with M. incognita. In recent years, FW has been reported more frequently in Georgia, which suggests that something affecting the disease complex may have changed. In 2015 and 2016, a survey of 27 Georgia cotton fields in 10 counties was conducted. At least 10 soil and stem samples per field were collected from individual plants showing symptoms of FW to quantify plant-parasitic nematode levels and identify Fov races. Fov race 1 was identified in all samples in 2015, but one sample also had the LA110 genotype and another sample also had the LA108 genotype. In 2016, all Fov races and genotypes found in 2015 were present, however, MDS–12 and LA127/140 also were found. Meloidogyne incognita was present in 18% of fields in 2015 and 40% in 2016, whereas B. longicaudatus was present in all fields in 2015 and 75% of fields in 2016. Regardless of whether they occurred separately or together, M. incognita and B. longicaudatus were present, respectively, in 18% and 55% of individual samples in 2015 and 40% and 51% in 2016. However, M. incognita without B. longicaudatus was found in 7% of samples in 2015 and 34% in 2016, whereas B. longicaudatus without M. incognita was found in 45% of samples in 2015 and 44% in 2016. We conclude that Fov race 1 continues to be the dominant race in Georgia and many instances of FW in Georgia may be due to Fov interacting with B. longicaudatus and not M. incognita as previously believed.
Experimental investigation of FeCO3 (siderite) stability in Earth's lower mantle using XANES spectroscopy

Abstract
We studied FeCO3 using Fe K-edge X-ray absorption near-edge structure (XANES) spectroscopy at pressures up to 54 GPa and temperatures above 2000 K. First-principles calculations of Fe at the K-edge in FeCO3 were performed to support the interpretation of the XANES spectra. The variation of iron absorption edge features with pressure and temperature in FeCO3 matches well with recently reported observations on FeCO3 at extreme conditions, and provides new insight into the stability of Fe-carbonates in Earth's mantle. Here we show that at conditions of the mid-lower mantle, ~50 GPa and ~2200 K, FeCO3 melts and partially decomposes to high-pressure Fe3O4. Carbon (diamond) and oxygen are also inferred products of the reaction. We constrained the thermodynamic phase boundary between crystalline FeCO3 and melt to be at 51(1) GPa and ~1850 K. We observe that at 54(1) GPa, temperature-induced spin crossover of Fe2+ takes place from low to high spin such that at 1735(100) K, all iron in FeCO3 is in the high-spin state. A comparison between experiment and theory provides a more detailed understanding of FeCO3 decomposition observed in X-ray absorption spectra and helps to explain spectral changes due to pressure-induced spin crossover in FeCO3 at ambient temperature.

Published: April 2019

Indonesian reading culture is very low. Various ways to increase interest in reading have been done by the government. Reading Reading Movement, National Movement of Literacy of Nations has been regulated in Law no 43 of 2007 and Permendikbud No 23 year 2005. In support of the program, this research is conducted in Community Literacy Movement by Leader's Reading Challenge (LRC) method. This initiative is a form of Community Empowerment in Tourism Awareness Group (TAG) Stone Garden of West Bandung regency. The study titled Use of Leader's Reading Challenge (LRC) Method in Improving Reading Interest of Tourism Awareness Group (TAG) of West Bandung Regency through Community Reading Garden. LRC is a method used from South Australia namely Premier Reading Challenge (RRC). The method used is descriptive qualitative research. By taking observation data, interviews, questionnaires, literature studies and documentation. Initial Conditions of the people who studied have low interest in reading because many factors cause. It is very influential is the low education, low economic and less facilitated to read and no activities of literacy movements in these tourist attractions. So after the research done, it appears the increase of reading interest with the indicator, reading activities in Community Reading Park (CRP) or in the tourist spot when .The indicator of reading success is that there has been the number of books read, there has been a review made also the existence of tree literasi. Internal factor which become indicator of success is with data of result of questionnaire expressing happiness after reading book. They feel happy with LRC Literacy activity. Constraints certainly exist, which is still a lot of interesting books to read, there are still activities that encourage people to motivate reading fond. There is still much more role and support from the government and the wider community in providing funds and also providing the means to manage Community Reading Gardens and the management of tourism literacy groups.
THE EFFORT OF THE EDUCATORS ON BUILDING POSITIVE CHARACTER ON EARLY CHILDHOOD STUDENT THROUGH ISLAM EDUCATION AT RAUDATUL ATHFAL IDAMAN
Authors: Sunarti Dwi Hayantini 
Published: April 2019

Childrens is a mandate from Allah SWT that entrusted to all parents which will eventually be asked for responsibility. Every childrens born pure and clean, both parents is making them into Jewish, Christian, Magi (HR Bukhari Muslim). So that childrens is a very weak person that will always rely to every human being around them. Physically one children is a base that can be build into so many shapes. Therefore all the childrens need a serious attentions, since every childs will absorbed everythings they see or hear because they have no power to refuse it. So it has become the responsibility of the parents or the people around them to give the attention about religious issues include, faith, worship, and morals. Because religion is a guideline to every humans life whether in this world and hereafter, so that its very affect every aspect in humans life whether its body or its soul. Every childrens that has potention from the day they born is possible to grow and can be fostered with religious values from an early age. If not properly fostered the period of physical and psychological development will be missed. This will be very harmful to every childrens, because if the development of their religious souls is good, they will keep it in their heart and will got an amazing values in their future. Al Qur’an saids that educations is one of the effort that will lead every human being to the way of Allah SWT with a thoughtfull ways, good advice will come with a good point of view too. Educations is a thing to one effort or process which held with consiousness, planned well and responsible, so that this required an educations method that fit perfectly to the target or an educations purpose that want to be achieve. The essence of religious educations is the foundations of religious morality to the childrens, while teaching is to give a knowledge to the protégé. Religious educations basically is to train (continue) rligious purity that every childs have since their birth, so that wont fade into atheism or even turn Into other religion except Islam. So that need to be our concern to habituate every child to do their responsibility to implement religious law and to stay away from its prohibition.

Fatty Acid Metabolism Disorder as a Factor in Atherogenesis
Authors: Osipenko Alexander N. 
Published: April 2019

Abstract

Background and aims: The study aims to analyze of fatty acid (FA) composition of arteries and blood plasma in atherosclerosis.

Material and method: The blood plasma in patients with coronary atherosclerosis was studied, the blood from healthy volunteers was used as control. There were also analyzed arteries of patients with severe atherosclerotic lesions and arteries of people with significantly less atherosclerotic changes.

Results: The received data indicates that there is a rather active penetration of FA from blood plasma lipoproteins into intima of arteries. Penetration of FA from blood lipoproteins into the depth of atherosclerotic aorta and an atherosclerotic plaque appears to be small and does not effect on their fatty acid composition, which is similar to that of free FA of blood plasma. The evidence of the increased activity of desaturases and fatty acid synthases in atherosclerotic and intact arteries in patients with severe atherosclerotic vascular lesions was obtained. This increase in activity may be related by relatively low content of polyunsaturated linoleic acid in blood plasma in atherosclerosis.

Conclusions: The increased activity of desaturases and fatty acid synthases as well as arterial wall hypoxia must promote accumulation of lipids in vascular wall by increasing the synthesis and inhibition of FA oxidation including free FA coming from blood.
