Democracia deliberativa e justiça restaurativa em medidas sócioeducativas: os jovens como sujeitos de direitos
Authors: Lima Cezar Bueno de , Silveira Jucimeri Isolda
Published: January 2018

O artigo sugere que a efetivação das políticas públicas destinadas à juventude pobre, autora e vítima de violência no Brasil está condicionada à ampliação de mecanismos político-institucionais de participação e deliberação popular nos processos de formulação, execução e acompanhamento de tais políticas. A adoção de mecanismos que fortaleçam a administração pública, orientada por princípios deliberativos e atuação interdisciplinar, pode promover espaços e processos de reconstrução de projetos de vida, na direção da ruptura de práticas tradicionais e criminalizadoras. O artigo sistematiza uma reflexão teórico-prática, na modalidade da pesquisa-ação, realizada na cidade de Curitiba-PR (Brasil), com o propósito de qualificar as políticas públicas e enfrentar os processos de reprodução da desigualdade e violações de direitos humanos dos adolescentes e suas famílias.
Auxílio-funeral na Assistência Social: atenção para quem?
Authors: Bovolenta Gisele Aparecida
Published: January 2018

O cuidado com o corpo morto é uma das atenções mais antigas que existe. No âmbito da política de assistência social está afiançado desde 1993 o auxílio-funeral como uma das modalidades de benefício eventual da Lei Orgânica de Assistência Social (LOAS) no campo dos direitos socioassistenciais. Esta reflexão propõe identificar o trato dispensado ao funeral ao longo da história e sua aproximação com a política de assistência social. A partir de uma análise bibliográfica, documental, legal e empírica, busca-se compreender o papel desse benefício nessa área e o modo como ele se encontra no país.

A rare case of Homicidal Mercury poisoning
Authors: Kaur Rupinder , Garg Parveen , Kaur Simran , Singh Jagminder , Chahal Harmandeep Singh
Published: January 2018

Mercury poisoning results from exposure to mercury in various forms. We report a case of homicidal ingestion of elemental mercury. Patient was managed with gastric lavage and chelation with British anti-Lewisite (BAL). Patient remained asymptomatic and developed no complications. He was discharged after 5 days in stable condition. Homicidal cases of mercury poisoning are rare. Elemental mercury ingestion usually does not produce complications as absorption from gastrointestinal tract is minimal.  Patient with mercury poisoning is managed with abstinence of exposure, gastric lavage and chelation therapy. Although elemental mercury poisoning usually does not cause complications but should be managed with care to minimize the risk if any.

Principal components analysis: theory and application to gene expression data analysis
Authors: Todorov Hristo , Fournier David , Gerber Susanne
Published: January 2018

Advances in computational power have enabled research to generate significant amounts of data related to complex biological problems. Consequently, applying appropriate data analysis techniques has become paramount to tackle this complexity. However, theoretical understanding of statistical methods is necessary to ensure that the correct method is used and that sound inferences are made based on the analysis. In this article, we elaborate on the theory behind principal components analysis (PCA), which has become a favoured multivariate statistical tool in the field of omics-data analysis. We discuss the necessary prerequisites and steps to produce statistically valid results and provide guidelines for interpreting the output. Using PCA on gene expression data from a mouse experiment, we demonstrate that the main distinctive pattern in the data is associated with the transgenic mouse line and is not related to the mouse gender. A weaker association of the pattern with the genotype was also identified.
Царь-производные в публицистических текстах
Authors: Гоннова Наталья
Published: January 2018

В настоящее время в разных стилях литературного языка и разных сферах общения отмечается наращивание такого пласта лексики, как царь-производные. Образованные по модели «слово + слово», они являются результатом вторичной номинации (производные по смыслу и морфологическому составу). Все царь-производные мотивированы лексемой царь. В сложносоставных существительных царь- выступает как оценочный (признаковый) компонент. Широкое распространение царь-производных автор статьи связывает с их сложным семным составом и коннотативными компонентами ‘лучший’, ‘выдающийся среди подобных’, ‘главный’, ‘сакральный’, ‘большого размера’, ‘обращённый к старине, к прошлому России’. В данной работе предпринимается попытка представить бытование царь-производных в сфере публицистики. Кратко охарактеризован публицистический стиль: его функции, информационные, аналитические, художественно-публицистические жанры. Акцент делается на важнейшей единице публицистического текста – заголовке. Обращается внимание на специфику выражения авторской позиции в текстах, содержащих царь-производные. Обосновано, что креолизованные публицистические тексты не только привлекают внимание читателя, но и воздействуют на него.
О новых и актуализированных значениях в русском языке
Authors: Кальнова Ольга
Published: January 2018

Отличительной чертой происходящих сегодня в лексико-семантической системе процессов является их динамизм. Мы нередко наблюдаем, как на наших глазах рождается новое слово или новое значение у известного слова, изменяется или нейтрализуется его стилистическая маркированность. Условием появления и закрепления нового или актуализированного значения является актуальность обозначаемого понятия и регулярная повторяемость в масс-медиа. Понятию «актуализированное слово» соответствуют разные лексемы, которые функционировали в языке ранее, но претерпели различного рода изменения семантического, стилистического, сочетаемостного, оценочного характера. Некоторые известные в русском языке слова – дочка, летальный, чистый, – частотные в общественно-политическом дискурсе, развивают новую сочетаемость, которая приводит к закреплению нового значения. Данный процесс может сопровождаться изменениями стилистической маркированности слова, чаще всего выражающейся в нейтрализации его разговорной и – реже – книжной окраски.

Зооморфная модель в концептуализации мира
Authors: Стоянова Елена
Published: January 2018

В концептуальной модели мира онтологические концепты, связанные с объектами окружающей реальности, представляются неким базисом. Среди них особое место занимают зооконцепты как первичные когнитивные структуры представления фрагментов действительного мира. Несмотря на значительный интерес к фразеологии с зоокомпонентом, а в последнее время – и к зооконцептам, зооморфная модель все еще остается в тени. Целью данной статьи является рассмотрение зооморфной мифологической модели как когнитивного механизма в языковой концептуализации окружающей действительности и особенности функционирования моделируемого знания в условиях современной лингвокультурной ситуации. Исследование осуществляется на примере концепта петух на материале русской фразеологии и метафорологии как языкового отображения действия когнитивных моделей в аспекте формирования новых смыслов.
Towards Improving South Africa's Legislation On Tax Evasion: A Comparison Of Legislation On Tax Evasion Of The USA, UK, Australia And South Africa
Authors: Storm Ansia , Coetzee Katrina
Published: January 2018

The fight against tax evasion in South Africa is an ongoing battle. The tools available to law enforcement boil down to legislation and the enforcement thereof.  The purpose of the study that was done for this article was to compare available legislation of the United States of America, United Kingdom, Australia and South Africa to determine if South Africa’s legislation can be improved. This was done by studying the relevant literature and legislation of all four countries. The findings, that there is some clauses that can be added to improve South Africa’s legislation, were confirmed by analyzing the legislation available. In theory, the results have proven that although South Africa’s legislation can compete with that of the United States of America, United Kingdom and Australia, there is some improvement that can be considered. This is of value to the individuals and professionals who deal with the offence of tax evasion on a daily basis, ensuring that the reviewed legislation will deter perpetrators or that the charges brought against them in the court of law will ensure harsher punishment.
A Generic Model Of Predicting Probability Of Success-Distress Of An Organization: A Logistic Regression Analysis
Authors: Bhandari Shyam , Johnson-Syder Anna J.
Published: January 2018

Many bankruptcy prediction models have been created over the years using a mix of variables derived mostly from accrual-based accounting statements and were industry specific. The primary issue with using a model comprised of accrual-based variables is that firm management can manipulate different components and make the balance sheet and income statement misleading (Wanuga 2006). Thus, firms appear financially healthy yet unable to meet the day-to-day cash flow needs of the firm; these financial issues are less likely to be hidden in the cash flow statement (Sharma 2001). In this study, we use a binary regression model with theoretically supported variables obtained from the cash flow statement to forecast firm success versus distress. Of particular interest, we examine firms representing 85 industries using firm data during and immediately following the greatest recession in United States history (Fieldhouse 2014; Lee 2014). The model is generic in the sense that it can be used to predict the probability of success-distress of any entity using the three major financial statements. We find that the overall model correctly classifies organizations 90.290 percent of the time.
ARANY JÁNOS LÍRÁJÁNAK ÉS VERSES EPIKÁJÁNAK RECEPCIÓJA A KORTÁRS MAGYAR KÖLTÉSZETBEN
Authors: FALUSI Márton
Published: January 2018

A tanulmány Arany János verses epikájának és lírájának kortárs recepcióját elemzi. Röviden bemutatja az életmű értékelésének hullámzásait, a verses epikus és a lírikus korszakok különféle értelmezési irányait, majd a kortárs magyar költészet Arany Jánoshoz való viszonyulását vizsgálja Nagy László, Juhász Ferenc, Orbán Ottó, Ágh István, Kányádi Sándor, Térey János és Lövétei Lázár László munkásságának középpontba állításával. A tanulmány alaptézise szerint fordulat következett be a hagyománytörténésben: a XX. században Arany János lírája látszott korszerűbbnek, mára viszont fölerősödött az epikus struktúrák recepciója. A szerző úgy véli, hogy a magyar költészet történetében akkor erősödnek föl az epikus struktúrák, amikor a költők az individualitás és a kollektivitás etikai problémáit nem ontikusan elválasztva, hanem szinoptikusan összenézve kezelik, s ennek révén tesznek kísérletet az olyan dichotómiák feloldására, mint klasszicizálás és romantika, látszat és valóság, egyéniesség és közösségiség, személyesség és tárgyiasság, affirmáció és alakváltoztatás, valóságreferencia és nyelvi játékosság, sajátszerűség és idegenség, eredetiség és mintakövetés, haza és haladás.
AZ IDENTITÁSTRAUMA/TRAUMATIKUS IDENTITÁS NYELVI ASPEKTUSA(I)
Authors: ČUDIĆ Marko
Published: January 2018

Aleksandar Tišma azok közé a gyermekkoruk óta két-, sőt többnyelvű, hibrid identitású írók közé tartozik, akiknél a nyelvválasztás egyáltalán nem magától értetődően, problémamentesen zajlott le. Tišma számára az a tény, hogy nem kis vívódás után végül a szerbhorvát nyelv mellett döntött, jelentős pszichológiai és kulturális, identitásbeli traumát okozott. A nyelviségből adódó alkotói válságai ráadásul magával a nyelvválasztással még korántsem értek véget, hiszen a kritikusok és a szerb író kollégák még évekig, évtizedekig kétségbe vonták (szerbhorvát) nyelvi kompetenciáját. Mindezekre a kritikákra Tišma rendkívül érzékenyen reagált, amiről legékesebben hosszú évtizedeken át írott naplóbejegyzései tanúskodnak. Azonban ha a világirodalom híres nyelvváltó íróinak „nyelvfilozófiájából” indulunk ki, mint például Vladimir Nabokov, Tišma többnyelvűségéből adódó, a többségi nyelvhez fűződő kisebbrendűségi érzése az újvidéki írót igazolja, hiszen az igazán nagy írásművészet egyik alappillére magának a nyelvnek az állandó megkérdőjelezése, problematikussá tétele, egy speciális, a sztenderdtől, a megszokottól némileg eltérő nyelv keresése, kialakítása és egyénivé tétele.

Published: January 2018

Coral shrimp (Panulirus spp.) or known as lobster is a potential fishery commodity and economic value. The demand for domestic and export market continues to increase both as local consumption and export. Indonesia is the largest lobster fishery producer in almost all Indonesian waters, from the west coast of Sumatra to the east coast Jayapura, one of which is Pameungpeuk beach, South Garut, West Java. As a result of increasing demand, fishermen try to catch as many lobsters and the impact of lobster prices also in creases and whereas fishermen continuously take it from nature. This study was conducted to determine the diversity and potential of lobster species especially living in high wavy waters along the southern coast of Garut (Pamengpeuk), West Java.The results of observation are only three types of crayfish, namely: a. Panulirus homarus (green lobster sand); b. Panulirus longipes (lobster flower/ red lobster) and Panulirus versicolor (green lobster/bamboo); is most commonly found in the area of south Garut, Pameungpeuk beach with high and strong waves. The percentage of female P longipes species (42.88%) was higher compared to male P. homarus (40%) and ovigerous female of P. versicolor (37.14%). While the sexual ratio between P. homarus (1:2.0:2.0); P. longipes (1:1.2:1.0) and P. versicolor: 1:1.2:1.2  which statistically showed significantly different p <0.05.

Freshwater fish is one of the biodiversity that build river ecosystem structure. Many human activities are carried out in the river as well as in the surrounding areas, such as removal of household waste, excessive fish exploitation and land use activities. This might changes river characteristics and lead to population and biodiversity decline.This research aim to 1) analyzethe diversity and species composition of fishin Luk Ulo River of Kebumen Regency,and 2) analyze the interaction among environmental factors with fish abundance in Luk Ulo River of Kebumen Regency. This research used survey method with cluster random sampling. The river was divided into three different region; upper-stream, middle-stream, and down-stream. Fish collected from 9 stations, i.e. 3 stations in the upper-stream, 3 stations in the middle-stream, and 3 stations in the down-stream. Morphology data were analyzed descriptively in order to make species description. The influences of environmental factor to species abundance were analyzed using Principal Component Analysis (PCA).The results showed that the number of fish obtained in this study were 72 individuals classified into 7 families and 13 species. The diversity and abundance of fish are influenced by physical and chemical factors ie temperature, TSS, pH, BOD5, COD, turbidity, DO, conductivity, salinity, current and substrate. BOD5 concentration was correlated positively with fish abundance with a correlation value of 0.540. In contrast, the effect of temperature and pH has a negative correlation to fish abundance with correlation values of -0.731 and -0.024. Dissolved oxygen (DO) and conductivity no effect on fish abundance.

Published: January 2018

Development of hybrid rice depends on the effectivity of cytoplasmic male sterility (CMS) and restorer (R) lines.  The molecular genetic approach is expected to help the breeder in identification of suitable parental lines to hybrid rice improvement. The study aimed to assess genetic relationship among three types of CMS systems (wild  abbortive/WA Kalinga and Gambiaca) as female parents and to identify diversity of genes controlling fertility restoration in rice. The study used nine F1 hybrids and F2 populations obtained from the hybridization of three different CMS lines (IR58025A-WA, IR80156A-Kalinga and IR80154A-Gambiaca) with three restorer lines (PK90, PK12 and BP11). Fifteen SSR markers were used to select genomic regions of chromosome 1 and 10 on which Rf3 and Rf4 genes located in the hybrids. The results showed that fertility restoration in CMS-WA and CMS-Gambiaca was governed by two independent and dominant genes (Rf3 and Rf4), while in CMS-Kalinga the fertility restoration was controlled by one single dominant gene. Biological processes occurred in the fertility restoration of the hybrids were the same based on the pollen and spikelet fertilities of F1 hybrids derived from three CMS and R lines, i.e. 76.1–78.3% and 69.1–76.6%, respectively. A restorer line PK12 had a higher capability in fertility restoration than PK90 and BP11. The SSR primers RM490 and RM258 were capable of identifying the Rf3 and Rf4 genes controlled fertility restoration in CMS-WA. The study supports the use of male sterile WA in rice hybridization. 

 
POLITICAL ECONOMIC ANALYSIS OF RICE SELF-SUFFICIENCY IN INDONESIA
Authors: Nuryanti Sri , Hakim Dedi Budiman , Siregar Hermanto , Sawit M. Husein
Published: January 2018

Rice self-sufficiency is an important programme in Indonesia. The programme has four major targets, i.e. increasing production, stabilizing prices and reserve stocks, and minimizing import. For that purpose, the government gave a mandate to a parastatal, namely National Logistic Agency (Bulog) in implementing the rice policies. Some studies found that involvement of such a parastatal could lead to government failure in budget allocation. The study aimed to estimate social cost of rice self-sufficiency programme based on the implementation of rice instrument policies by Bulog. The study used the national annual data of 2002–2014 period. The method used was the political preference function model to estimate economic rent and dead-weight loss using rice price elasticity of demand and supply. The result showed that in terms of percentage of food security budget, the average of economic rent reached IDR 6.37 trillion per annum (18.54%), while the average of dead-weight loss amounted at IDR 0.90 trillion per annum (2.34%). It proved that rice self-sufficiency programme along with the involvement of Bulog was economically inefficient. The government should provide better agricultural infrastructure, review governmental procurement prices, and stop rice import policy to remedy market failure.
Newly Developed, Highly Automated Apparatus for Rapid Evaluation of Stimulation Fluid Additives
Authors: Recio Antonio , Benoit Denise , Potty Ajish , Sun Jianlei , Henkel Kristina
Published: January 2018

This paper describes the development of a highly automated apparatus and customized software package to rapidly evaluate the performance of surfactant additives in dry gas shale reservoirs. A major challenge throughout the industry is the ability to reduce water saturation resulting from fluid leakoff into the formation matrix during stimulation operations. The new method presented in this paper to help identify the optimum surfactant for reducing post-treatment water saturation based on well-specific parameters. Conventional laboratory evaluation of stimulation fluid additives typically involves coreflow studies, which are excessively time consuming and have poor reproducibility as a result of core-to-core inconsistencies. The focus of this endeavor was to develop a statistically relevant method that can use drill cuttings samples and measures surfactant additive performance data with high confidence and reproducibility for the tested formation material.

Data analysis included analysis of variance (ANOVA) followed by post-hoc Tukey honest significant difference (HSD) range testing. Test apparatus results were also corroborated with coreflow studies. Eight surfactant additives were evaluated in the presence of four different fracture fluid formulations and formation samples. For each surfactant/fracturing fluid/formation test matrix, the software was able to rank surfactants performance based on the volume of fracturing fluid displaced from a column pack normalized to the pressure gradient. No individual surfactant performed best more than 40% of the time within this test series, and the surfactant-laden formulations always statistically outperformed the nonsurfactant control. The results imply that the addition of surfactants results in increased treatment fluid load recovery. Reservoir simulations were performed to investigate the effects of increased load recovery and depth of invasion of fracturing fluids on hydrocarbon production. The simulation results confirmed the assumption that minimal invasion of treatment fluid into the matrix of the formation resulting from increased load recovery does improve hydrocarbon production. The simulation data also suggest this observed hydrocarbon production improvement is particularly prevalent in the early time/cleanup period of the life of the well.

A key feature and novelty of the apparatus is the ability to evaluate numerous surfactants in series and the potential to perform up to 24 individual tests in an 8-hour shift. The results presented in this paper showcase the utility of the newly developed apparatus, which offers a new method for rapid customization of stimulation fluids.
A Theoretical Study of the Effect of Salt Precipitation on CO2 Injectivity

Published: January 2018

Adequate well injectivity is required to successfully inject large volumes of CO2 through a minimum number of wells. Brine vaporization in the wellbore vicinity has been identified as a major CO2 injectivity impairment mechanism especially in deep saline reservoirs. A bundle-of-tubes model was developed to investigate basic mechanisms of salt precipitation and to quantify injectivity loss induced by precipitated salts during CO2 injection into saline formations. A Berea sandstone rock was reconstructed with a bundle-of-tubes model. A correlation was developed to estimate the solid salt saturation in the pores based on the properties of the aqueous phase. A parameter capable of tracking the development of the dry-out zone was introduced to model the distribution of salt in the pores. A relative injectivity change index was then used to quantify injectivity impairment induced by precipitated salts. A tortuosity factor was incorporated to account for the tortuous path taken by fluids in porous media. A sensitivity study was performed to assess the effects of parameters such as brine salinity, initial permeability, injection flowrate and porosity on injectivity loss. The model can reproduce some experimental results of drying of brine-saturated sandstone cores by supercritical CO2. A sensitivity study of the parameters affecting injectivity show that; (1) salt precipitation occurs in the dry-out zone where most of the irreducible water in the trapped brine has evaporated, (2) increasing brine salinity has adverse effect on injectivity, (3) salt precipitation affects permeability more than porosity and (4) in rocks with high initial permeability, salt precipitation is minimal. These findings are important for a successful CCS project since CO2 injectivity controls essential aspects of storage which are the rate, the quantity and length of time for CO2 injection into a formation.
Investigating Impact of Rock Type and Lithology on Mud Invasion and Formation Damage

Published: January 2018

Formation damage from mud invasion is a complicated process that is influenced by mud type, downhole fluid particle size distribution (PSD), mud rheology, rock type, lithology, permeability, drill pipe rotation, geochemical factors, pressure, and temperature. Many of these variables are often ignored, simplified, or underestimated. Thus, their individual and combined effects on formation damage is not well understood. Among these factors, the porous media complexities play a key role in determining the extent of drilling mud damage to the formation.

This paper is focused on characterizing water based mud's (WBM) invasion and damage to different rock cores representing various lithologies, under simulated dynamic wellbore condition. The experiments performed in this study were selected from a statistical design of experiment method. Based on formation damage relevance, the following factors were considered and varied: pore throat diameter of homogenous porous media (ceramic filter tubes), lithology type, and temperature. The levels of each factor were determined from a mud invasion data base considering high and low limits. Other constant factors were rotary speed, type of lost circulation material (LCM), concentration of LCM, and pressure. An LCM was carefully added to the WBM to reduce the fluid's invasion. Dynamic wellbore condition (pipe rotation only) was simulated with a drilling simulator, capable of rotating a shaft that is centered between the inner diameter of the damaged porous media. Using this approach, the formation damage profile of the WBM on four different lithologies was investigated. The results revealed that rock permeability and porosity are critical factors that control mud invasion, damage propensity, and filter cake permeability profile. Statistical analysis showed that increase in temperature can significantly increase the degree of mud solids cross flow and fines mobilization through the porous media. Thus, leading to the reduction of formation permeability. In a radial system, ceramic filter tubes representing homogenous porous media are often used to quantify mud invasion. However, further investigation revealed no significant change in the damage profile exhibited by the two (5μm and 20μm) pore throat diameter filter tubes used in this study. These filter tubes are typically calibrated to match permeability values of actual rocks, but are not true representation of lithology complexities. The novelty of this study lies in integrating different constant and varying mud invasion factors in relation to the damage of four lithology types.
Development of Environmentally Friendly Epoxies for Well Conformance
Authors: Bertram F. , Tuxen A. , Nielsen T. B.
Published: January 2018

Non-conformance is a common reason for lower oil production in mature fields, and there is a great need for new conformance chemicals that can help restore well conformance and improve reservoir sweep. This paper discusses the development and testing of a new environmentally friendly epoxy that can improve well conformance. A new epoxy formulation has been developed and it is based entirely on environmentally friendly chemicals. This formulation has characteristics similar to conventional epoxies, such as strength and tunable curing time. The developed epoxy offers an environmentally friendly alternative to conventional epoxies and resins, which rely on chemicals that are toxic to the aquatic environment. This epoxy may also be used for well abandonment or hydraulic fracturing.
Modern Fracturing Revitalizes Dormant Technologies: A Case History

Published: January 2018

Innovation continues to be a driving force within the petroleum industry, particularly in the service sector. Technological breakthroughs often differentiate winners and losers in this highly competitive environment and frequently lead to improved production and real value. Advances this century in hydraulic fracturing technologies have combined to reshape the global oil market by making tight gas and mudstone unconventional plays more viable. Conversely, technologies developed decades ago have also consistently shown new life and new applications when combined with these recent technological innovations.

The successful application of a revitalized non-aqueous hydraulic fracturing fluid system, first developed in the early 90's for diesel and crude oil to tackle some of the most sensitive and technically challenging formations, is documented in this case history. A brief summary of the historical application of this fracturing fluid system and the reasons for lack of applications is included. The current application of this technology, in tandem with a new refined mineral oil based fluid system energized with CO2, found new life for stimulation of the multifaceted Vicksburg formation in South Texas. Vicksburg formation characterization, treatment designs and post-treatment well production performances are reviewed. A short formation evaluation and engineering analysis are also provided to help understand the formation-related challenges and working mechanisms for this fracturing fluid system.

Offset wells completed with alternate technologies during the same time period were weighed against wells treated with the updated 1990's era technology. The revitalized system surpassed these comparative technologies in terms of both cumulative hydrocarbon production and decreased decline rates.

This case history demonstrates not only the efficacy of the documented fracturing treatment design, but also the value in combining old and new technologies as an effective method to provide innovative solutions in challenging reservoirs.
Downhole Gauge Data Analysis of Open-Hole Gravel Packing Treatments: Methodology and Examples

Published: January 2018

Downhole gauge (DHG) data analysis is a powerful tool in not only identifying, or minimizing the potential number of, root causes for any failures that may occur during gravel packing, but also in either verifying or calibrating friction pressure data used in gravel placement simulations. Although downhole pressure and temperature gauges are often used in open-hole gravel packing and expertise in analyzing the data certainly exists in companies that routinely use downhole gauges, there is no publication that comprehensively discusses the methodology. DHG data analysis in general requires more information than the gauge data itself. This includes logs, wellbore schematic, pumping schedule, fluid properties, return flow measurements, daily rig reports, and data relevant to displacements.

The objective of this paper is to provide guidelines for DHG data analysis to completion engineers who are not routinely involved and thus not experts in such analysis, by detailing the factors that must be kept in mind, offering a methodology and demonstrate the methodology with several examples.

Published: January 2018

We derive a general system of equations accounting for two-phase fines migration with fines mobilization by injected water with different salinity, rock plugging by the migrating fines and consequent permeability damage in the swept reservoir zones. The analytical model derived contains explicit formulae for water-saturation and ion-concentration fronts along with pressure drop and water-cut in production wells. The model developed is applied to the cases of heavy oils, in low consolidated rocks with different clay composition and different injected and formation water compositions.

We show that non-equilibrium effects of the delayed fines release highly affect incremental oil during injection of different-salinity water. The oil-recovery is maximum for fast fines release. For slow fines release, the recovery tends to that of "normal" waterflooding.

The fines-migration-assisted smart waterflood is successful in reservoirs with a high content of fines-generating clays in the rocks (kaolinite, illite, and chlorite).

A novel analytical model presented in the paper allows predicting reservoir behavior and incremental oil for different compositions of injected water and clay contents in the rock. It permits recommending ionic-composition for the injected water.
Skin Factor Equations for Anisotropic Wormhole Networks and Limited Entry Completions
Authors: Schwalbert Mateus Palharini , Zhu Ding , Hill A. Daniel
Published: January 2018

It was recently shown that anisotropic wormhole networks may arise from the acidizing of anisotropic carbonates. In openhole or cased and densely perforated completions, where in isotropic formations the wormhole network would be expected to be radial around the well, the actual stimulated region may be elliptical in anisotropic formations. Analogously, in completions where the limited entry technique is used, the wormhole network is expected to be spherical in isotropic formations, but it may actually be ellipsoidal in anisotropic formations. That has an impact on the well performance and should be taken into account when designing the acidizing treatment and the completion. At the same time, the use of a limited entry technique may result in better stimulation coverage and also longer wormholes, but it may also result in a partial completion skin factor, impairing the productivity from the stimulated well. This should be taken into account when estimating the stimulated well productivity.

In this study two main topics are analyzed: the impact of wormhole network anisotropy and the impact of a limited entry completion. Both radial and spherical wormhole propagation patterns are considered, to be applied in both openhole and limited entry completions. The differences in well performance is studied for each case, and analytical equations for the skin factor resulting from each scenario are presented.

The anisotropic wormhole networks are obtained from numerical simulations using the averaged continuum model, and the results are validated with experimental data. The analysis of the well performance is made through simulation of the flow in the reservoir with the different stimulated regions.

The results show that for highly anisotropic formations the wormhole network anisotropy may have a great impact on the acidized well performance and this should be taken into account in the acidizing treatment design. It was observed that the anisotropic wormhole networks present lower productivity than equally sized isotropic stimulated regions. Hence, equations like Hawkins formula should not be used for estimating the skin factor from anisotropic wormhole networks, and the equations proposed in this work should be used instead.

Specifically, the impact of anisotropic wormhole networks is large when the limited entry technique is used. It is shown that for this type of completion there is an optimum stimulation coverage of about 60 to 70%, and the perforation density required to obtain for a given acid volume depends strongly on the wormholes' anisotropy. The skin factor equations proposed in this work for the stimulation with limited entry completion should be used for obtaining the optimum perforation density for a given scenario.
