Authors: Biazin Gonçalves Fellipe , Vicentini de Oliveira Daniel , Andrade do Nascimento Júnior José Roberto , Serra de Araújo Ana Paula
Published: January 2016

O presente estudo tem como objetivo avaliar a qualidade de vida e os indicativos de depressão em idosas praticantes de exercícios físicos em academias da terceira idade (ATIs). O estudo foi realizado com 41 idosas praticantes de exercícios físicos em ATIs. Para avaliação da qualidade de vida foram utilizados os instrumentos WHOQOL-Bref e WHOQOL-Old, e para avaliação dos indicativos de depressão, a Escala de Depressão Geriátrica. Os resultados obtidos indicaram que as idosas avaliadas obtiveram escore de 80,6 no WHOQOL-Bref e 72,6 no WHOQOL-Old, valores considerados bons. Quando avaliados os domínios e facetas dos questionários WHOQOL, o domínio que apresentou maior qualidade de vida foi o de auto avaliação da qualidade de vida (16,6±2,6), já o menor foi o de meio ambiente (15,8±2,0). Em relação às facetas, a que apresentou maior qualidade de vida foi a de participação social (76,0) e a menor a de Autonomia (62,6). A média da escala de indicativos de depressão geriátrica foi de 2,2±1,6, valor considerado baixo e positivo. Ao avaliar a escala de indicativos de depressão geriátrica, verifiou associação significativa de que as idosas sem indicativos de depressão tem uma qualidade de vida no domínio físico superior a idosa com estes indicativos (p=0,033093), assim como entre indicativos de depressão e tempo de prática de exercício físico (p=0,00416). Conclui-se que idosas que praticam exercícios físicos nas ATIs possuem boa qualidade de vida geral, assim como nos domínios e facetas avaliadas, além de baixos índices de indicativos de depressão.

Published: January 2016

Na região de Lagoa Formosa e Carmo do Paranaíba (Alto Rio Paranaíba), situada no oeste de Minas Gerais, afloram rochas metassedimentares pertencentes ao Grupo Bambuí, rochas sedimentares cretácicas pertencentes ao Grupo Areado e rochas vulcânicas e vulcanoclásticas pertencentes ao Grupo Mata da Corda. As rochas neoproterozóicas do Grupo Bambuí, compreendem duas associações de fácies: associação de diamictitos maciços e associação de arenitos, conglomerados, siltitos e carbonatos. Estas associações são representadas por litologias variadas que envolvem contextos diferenciados de deposição. As associações de fácies descritas neste trabalho sugerem uma sedimentação dominada por fluxos gravitacionais subaquosos, com fluxos de detritos e lama e correntes de turbidez, que caracterizam uma sedimentação de leque submarino, em uma bacia do tipo foreland. Esta seqüência metassedimentar foi deformada no final da Orogênese Brasiliana, apresentando, principalmente, dobras assimétricas e foliação na forma de clivagem ardosiana.Palavras chave: Grupo Bambuí, sedimentação, estratigrafia, reconstituição paleogeográfica, bacia de ante-país. ABSTRACT: THE LAGOA FORMOSA FORMATION, BAMBUÍ GROUP (MG).

On the Lagoa Formosa and Carmo do Paranaíba region, situated in western of Minas Gerais state, outcrop neoproterozoic metasedimentary rocks of Bambuí Group, remnants of cretaceous sedimentary rocks of Areado Group and volcanic rocks of Mata da Corda Group. The Neoproterozoic Bambuí Group shows two facies associations: (1) massive diamictites; (2) sandstones, conglomerates, laminated siltstones and carbonates association. These facies associations exhibit various lithology that involve different depositional systems. These facies associations suggest a slope and base-of-slope systems with subaqueous gravitational flows (submarine fans depositional systems) on a foreland basin context. This neoproterozoic sequence was deformed at the end of Brasiliano Orogeny (~600Ma), showing assymmetric folds and slaty cleavage.Keywords: Bambuí Group, sedimentation, stratigraphy, paleogeographic reconstitution, foreland basin.

O processo de urbanização e as alterações do meio físico decorrentes do uso do solo constituem um fator gerador de problemasambientais. A concentração populacional aliada à falta de um planejamento de ocupação tem motivado o uso inadequado do espaçourbano, provocando a ocorrência de sérios desequilíbrios ambientais. Esses desequilíbrios quando ocorrem em áreas com característicasfísicas impróprias à ocupação, como aquelas cujas condições ambientais, resultantes da combinação de fatores geológicos,geomorfológicos, pedológicos e topográficos, dentre outros, favorecem a ocorrência de processos erosivos e movimentos de massa. Estetrabalho tem como objetivo avaliar os fatores que interferem na definição da susceptibilidade a erosão e movimentos de massa nomunicípio de Ibirité/MG. Foram analisados os seguintes fatores condicionantes: características geológicas, morfologia; e também os fatoresdeflagradores provocados pela ação antrópica. Por meio dessa análise foi produzido um mapa identificando as áreas de maior e menorsusceptibilidade á erosão e movimentos de massa. O município apresenta a maior parte de seu terreno com moderada susceptibilidade,sendo assim, o uso do solo deve ser planejado para que a ocupação seja adequada de forma a minimizar o risco de ocorrência de processoserosivos e movimento de massa. O poder público deve fiscalizar essa ocupação, verificando se existe a presença da infra-estruturanecessária nos loteamentos.Palavras-chave: SUSCEPTIBILIDADE A EROSÃO, MOVIMENTO DE MASSA, PROBLEMAS AMBIENTAIS ABSTRACTEVALUATION OF SUSCEPTIBILITY TO EROSION AND MASS MOVEMENTS IN THE MUNICIPALITY OF IBIRITE. The process ofurbanization and changes in the physical environment resulting from land use are a key driver of environmental problems. The populationdensity and lack of planning occupancy has motivated the inappropriate use of urban land, causing the occurrence of seriousenvironmental problems. These problem when occur in areas with physical characteristics inappropriate for occupation, as those whoseenvironmental conditions come from the combination of geological, geomorphological, pedological and topographical factors, amongothers, favor the occurrence of erosion and mass movements . This study aims to assess the factors affecting the definition of susceptibilityto erosion and mass movements in the municipality Ibirité / MG. The following conditioning factors were analyzed: geological,morphological characteristics; and also the trigger factors caused by human action. Through this analysis was produced a map identifyingareas of high and low susceptibility to erosion and mass movements. The city has most of its terrain with moderate susceptibility, thus theland use should be planned so that the occupation need to be adequate to minimize the risk of erosion and mass movement. Thegovernment should monitor this occupation, checking if there is presence of the necessary infrastructure.Keywords: SUSCEPTIBILITY THE EROSION, MASS MOVEMENTS, ENVIRONMENTAL PROBLEMS

Published: January 2016

Geodiversidade é uma nova abordagem ambiental que vem sendo utilizada na compreensão das relações entre homem e território e refere-se aos elementos abióticos que compõem o meio ambiente. Rochas são a expressão mais evidente dessa geodiversidade e seu aproveitamento como material nobre em arquitetura e engenharia civil remonta às primeiras construções humanas. São um reflexo da geodiversidade disponível numa região e imprimem nos cenários construídos uma característica particular de identidade cultural. Cemitérios são um universo que possibilita o entendimento do mundo dos vivos ao longo das diferentes épocas em que foi utilizado e o Cemitério Municipal de Curitiba é o mais antigo do município, recebendo visitação de pesquisadores e interessados nos aspectos arquitetônicos, históricos, artísticos e sociológicos. Esta proposta apresenta a geodiversidade deste cemitério como uma leitura sobre a evolução no uso de materiais líticos pela sociedade curitibana. As rochas registradas são mármores importados e nacionais, granitos do Paraná e São Paulo, e rochas negras como diabásio e gabro. Outras rochas estão presentes em menor quantidade e apresentam variedade de procedências. A proposição de tombamento deste cemitério como bem cultural vem recebendo aporte de várias pesquisas e, entre elas, este levantamento é um subsídio para este processo.Palavras-chave: CEMITÉRIO, GEODIVERSIDADE, TÚMULOS, CURITIBA ABSTRACTGEODIVERSITY IN CURITIBA MUNICIPAL CEMETERY AS CULTURAL ELEMENT IN HERITAGE ANALYSIS.

Post-collisional to late orogenic magmatism (570 to 480 Ma) in the Araçuaí-Ribeira Foldbelt is characterizedby the predominance of high-K metaluminous, allanite-sphene-bearing granitoids. Smaller lenses of coroniticgabbro, anorthosite, pyroxenite and phlogopite-peridotite are also common in deeper exposed areas of thisfoldbelt. Several large plutons (³ 100 km2) were mapped by the authors and co-workers in a 1:25,000 scale.In southern Espírito Santo, the deep erosional level associated with a steep topography reveals the internalarchitecture of these intrusions: a tendency to funnel-shaped bodies, with sub-vertical cylindrical roots,grading to shallower angle dipping tops. Associated stocks, sills and dikes of basic and acidic magmasgenerally intrude the enclosing gneisses along the foliation planes, local ductile shear zones and fold axes.The contact to these enclosing rocks is sharp in deeper eroded plutons (Santa Angélica, Venda Nova,Mimoso do Sul and Várzea Alegre). Where higher levels are exposed (Castelo, Pedra Azul and Conceiçãode Muqui), agmatic stoping zones dominate along the borders. The igneous foliation is usually well markedand the schistosity of the surrounding gneisses wrap around the plutons. Each intrusion has a uniquemarble cake (bimodal) internal structure: concentric patterns of more basic to intermediate cores aresurrounded by interfingered lenses of basic to acidic magmatites. Syenomonzonite and granite mark theborders. Widespread evidence of mingling and mixing between contrasting magmas of gabbroic and graniticand/or syenomonzonitic compositions is characteristic for all intrusive complexes. Probably due tolithospheric delamination following collisional orogenesis, the upwelling of hot asthenospheric magmasinduced partial crustal melting. The interaction of these contrasting magmas originated the bimodal plutons.Their emplacement followed older regional paths such as regional fold axes and ductile shear zones.

This study intents to analyze with the mechanical work of the rain runoff in the region of Gouveia - EspinhaçoMeridional, State of Minas Gerais, Brazil, under natural conditions and not induced rainfall. It showssignificant differences in the denudation processes taking place on the ground surface, due to the variationof micro-forms and the vegetation cover.The hydro-erosive date for the period between February and September/00 indicate a more acceleratedlowering of the ground surface on the lower slope. In the areas with lower vegetation cover, the runoff flowcuts down the soil surface, deepening the micro-ravines. In other places of the slope where the hydrologicalforces are week and vegetation cover thicker, a higher stability of the micro- topography and a more moderatedeposition of the sediments can be observed.

RESUMO:

Para a consolidação da linguística como ciência madura foi necessária, além da compreensão de fundamentos universais de todas as línguas, formação das ideias da gramática universal (esta temâtica tem atraído a atenção de historiógrafos), o entendimento do caráter universal de propriedades da língua. A análise dos monumentos filológicos portugueses dos sécs. XVI e XVII possibilita estudar o mecanismo da universalização dos conceitos de apologia da língua materna, de norma, história, linguodidática, elaborados primeiro com base de uma língua concreta e logo aplicados a outras línguas, à língua em geral, a LÍNGUA.

The importance of nosocomial infections caused by coagulase-negative staphylococci is constantly growing. The threat primarily affects immunocompromised patients, the elderly and neonates, particularly after invasive surgery. The problem is fundamentally exacerbated by expanding antibacterial drug resistance. A case report is presented of an 86-year-old patient who underwent a ruptured abdominal aortic aneurysm surgery and developed septicaemia upon surgical wound infection. The causal agent was likely a carbapenem-resistant Klebsiella pneumoniae, however, daptomycin-resistant Staphylococcus pettenkoferi was identified in blood cultures in the absence of daptomycin treatment. To the authors' knowledge, the case study presented is the first published episode of daptomycin-resistant S. pettenkoferi strain.

Published: January 2016

Tulisan ini melakukan kajian terhadap praktek jual sanda dalam masyarak Banjar di Hulu Sungai. Praktek ini marak dilakukan sebagai bagian dari mekanisme masyarakat petani, khususnya yang berdomisili di Hulu Sungai Tengah dalam mengatasi persoalan ekonomi yang mereka hadapi. Temuan peneliti menjelaskan bahwa, meski terdapat persoalan hukum, baik dilihat dari kacamata hukum positif dan hukum Islam, praktek jual sanda tetap menjadi pilihan masyarakat. Adanya ketidakmampuan bank dan koperasi dalam menjangkau kebutuhan masyarakat menjadi salah satu penyebab dari tetap langgengnya praktek ini. Pertimbangan agama, tidaklah berlaku dalam masyarakat adat, yang walaupun semua pihak yang bertransaksi memiliki pengetahuan yang cukup dalam agama Islam. Mengutip teori rasionalitas praktisnya Max Weber yang memandang bahwa segala aktivitas manusia yang ada di dunia ini selalu dikaitkan dengan pragmatis dan egoitis, maka praktek ini dapat dipahami, yaitu kedua pihak menginginkan kemudahan dan kepraktisan. Kemudian adanya pihak yang berkuasa (superior) menindak pihak yang lemah.

TUAN GURU AS CAMPAIGNERS: POLITICAL PLAYERS AND SELF INTERESTED LEADERS?
Authors: Muhajir Ahmad
Published: January 2016

Tulisan ini mengkaji para tuan guru Banjar yang terlibat dalam kampanye pemilihan kepala daerah (pilkada) di Kalimantan Selatan. Dengan pilkada gubernur 2005 sebagai studi kasus, penulis ingin menguji apakah para tuan guru tersebut merupakan pemimpin masyarakat dengan kepentingan pribadi semata. Studi ini juga meneliti sejauhmana para ulama Banjar ini mau terlibat dalam kampanye dan apa yang menjadi pertimbangan-pertimbangan mereka. Para ulama yang menjadi narasumber adalah mereka yang dilibatkan, baik secara langsung ataupun tidak, dalam usaha menarik suara pemilih oleh empat dari lima pasangan calon yang bersaing saat itu. Penelitian ini menunjukkan bahwa tuan guru yang diteliti memilih cara yang berbeda dalam membantu calon mereka. Ada yang berkampanye begitu rajin di berbagai ajang dan forum baik yang resmi untuk kampanye atau tidak, namun ada pula membatasi diri hanya pada acara-acara tertentu. Mereka mempunyai motif dan pertimbangan masing-masing baik politik maupun ideologis yang membuat mereka melangkah hingga titik tertentu: mereka berhitung secara rasional. Sebagai imbalan atas kesediaan mereka, para calon memberikan sejumlah ganjaran baik untuk pribadi maupun pesantren, pengajian ataupun organisasi yang dipimpin oleh para ulama ini. Penulis menyimpulkan bahwa tuan guru Banjar yang turut serta berkampanye tidak hanya mengusung kepentingan pribadi.

Understanding students’ satisfaction and continuance intention of e-learning: Application of expectation–confirmation model
Authors: Tiyar Forouzan Rezaeian , Khoshsima Hooshang
Published: January 2016

The evolution of technologies leads to the great significance of e-learning in the domain of education. Recognition of the crucial factors which influence learners’ aims towards continued use of e-learning would guide teachers, learners and e-learning developers to increase e-learning use. To this end, the present study investigates the Expectation-Confirmation Model (ECM) factors of Post-Adoption Expectation (PAE) which is explored via using language learners’ post-adoption experiences in the use of e-learning systems. Learning process, tutor interaction, peer interaction, and course design are the four factors identified used for extending the perception of language learners’ experiences in e-learning. The survey method was used to empirically validate the suggested model (ECM) of the present study. A total sample of 120 Iranian university students participated in the study.In order to investigate the proposed model, structural equation modelling employing Smart PLS 2.0 was run. The findings indicate that learners’ confirmation of using e-learning has a significant effect on the four aforementioned factors. Learning process and course design are the only two factors that have a significant effect on users’ satisfaction and continuance intention. On the other hand, the results showed that tutor interaction and peer interaction do not have a significant effect on predicting learners’ satisfaction and continuance intention of e-learning systems. Keywords: e-learning, students’ satisfaction, students’ continuance intention, expectation-confirmation model, post-adoption expectation

It focused on examining language teachers’ stances on implementing the principles of critical pedagogy in their classrooms. Also, of particular interest was the study of gender difference in practicing critical pedagogy in language institutes in Iran. At first, the Critical Pedagogy Implementation Inventory, developed by Mozaffari (2011), was administered to 116 instructors teaching at language institutes to collect the required quantitative data. In the second phase of the study, forty-six of the participants were interviewed to gather some complementary qualitative data. The researchers utilized descriptive statistics, factor analysis, Cronbach’s Alpha, chi-square, and independent samples T-test for the quantitative phase of the study, and techniques based on grounded theory in the qualitative phase. Data analysis revealed that the majority of language teachers were in favor of practicing critical pedagogy in their classrooms. However, it was found that critical pedagogy is not efficiently practiced in Iranian educational contexts and even the teachers who advocated the principles of critical pedagogy had an almost average score on the Critical Pedagogy Implementation Inventory. In fact, the teachers claimed that there were some barriers to practicing critical pedagogy in Iran. The top-down educational system, prescriptive approaches to supervision, class size, learners’ expectations, conventional teacher-student relationships, and their traditionally-defined roles were among the main hurdles that impeded an appropriate implementation of critical pedagogy in classrooms. Further investigation also revealed that there was a significant difference between male and female teachers’ stances on practicing critical pedagogy. It was revealed that female instructors tended to be more positively immersed in such implementation. Keywords: critical pedagogy (CP), educational contexts, foreign language teachers, prescriptive supervision

Variable Pump Rate Fracturing Leads to Improved Production in the Marcellus Shale
Authors: Ciezobka Jordan , Maity Debotyam , Salehi Iraj
Published: January 2016

Typical hydraulic fracturing designs in shale utilize a predetermined fluid pump rate, which once achieved is held constant throughout the treatment, excluding situations when surface pressure limitations or other conditions disallow. We propose a method of pumping hydraulic fracture stages where the fluid pump rate is rapidly changed from the predetermined maximum rate, to some significantly lower rate, and then rapidly increased back to original maximum rate. This rapid change in the flow rate produces a pressure pulse that travels up and down the wellbore and has the capacity, together with the pump rate change, to open previously unopened perforations, while increasing fracture complexity through fluid diversion.

We observed increased microseismicity during hydraulic fracturing in stages with frequent pump rate changes. Regardless of their type and nature, seismic signals are indicative of fragmentation of the treated zone. This could be from shear shattering or dilatational opening. One can also assume that high signal density is a good measure of fracturing efficiency. To further investigate these observations, we implemented a variable pump rate fracture design in a Marcellus shale well. More specifically, we implemented the variable pump rate frac design in every odd stage, while implementing a constant rate design in every even stage. This was done in order to account for changes in the reservoir along the horizontal lateral.

Production log results showed on average a 19% increase in production for the variable pump rate stages versus the constant pump rate stages. A lower treating pressure was often encountered after the rapid rate changes, leading to the conclusion that unopened perforations were opened with the aid of the induced pressure pulses. Total well production decline was much slower for test well that included variable pump rate changes versus the offset horizontal well which did not include the variable pump rate frac design.

And finally water hammer frequency decay analysis shows a predictable trend in well with variable pump rate stages. Throughout the variable pump rate stages, no proppant transport issues were encountered and the frac stages were completed without any major issues.

Rapid rate changes applied throughout the fracture treatment enhance microseismicity, which could be interpreted as additional fracture complexity. Surface fracturing pressure data shows that rapid pump rate changes open additional perforations without physical flow diverters such as ball sealers or frac balls, while production log data shows higher production. Implementation of the Variable Rate hydraulic fracturing method results in no additional costs while it increases stimulation efficiency.

The struggle to define an optimized completion strategy remains a significant challenge in unconventional multistage horizontal wells. Stage and cluster spacing is a design decision that often requires significant experimentation to determine what is the optimized spacing of propped fractures that efficiently drains the reservoir yet can be reliably pumped to completion. This paper illustrates the importance of bottomhole (BH) gauge data for evaluation of stage and cluster spacing and general completion quality. The knowledge derived through careful analysis of this valuable data source, can significantly reduce the amount of experimentation typically required in other completion techniques. Consequently optimized field scale completion strategies can be refined with efficiency and reduced overall costs.

Coiled tubing (CT) assisted hydraulic fracturing (HF) is a good alternative to the standard plug and perf completion in multistage horizontal well stimulation. During a CT HF operation, fracturing is initiated via pre-installed frac sleeves or sand-jetted perforations. One of the advantages of CT fracturing is improved target fracturing, where a single-entry fracture initiation point can be placed at the desired depth to target the best rock for stimulation. Another benefit of CT fracturing is the ability to gather BH treating pressure via BH gauges (BHG) mounted on the CT bottomhole assembly (BHA). Bottomhole pressure and temperature gauges, installed above and below the isolation packer, provide valuable information about fracture communication between stages, cement integrity and stress shadowing.

This paper will review dozens of CT frac jobs performed across various basins in North America. Information obtained from BHG is merged with surface treating pressure and other diagnostic data sources and subsequently analyzed. One key area of analysis is to examine stage communication data for stress shadowing effects. The primary takeaways from this paper are to illustrate the importance of BHG data, how it compares to other diagnostic data, and how it can be analyzed to effectively drive the stimulation design process.
The Good, the Bad and the Ugly: A Case History of a Multi Stage Hydraulic Fracturing Horizontal Well Tight-Gas Development in Oman

One often overlooked aspect of hydraulic fracturing is that the majority of reasonable permeability reservoirs (0.1 mD and above), on the North American continent, were in fact originally completed with straightforward hydraulically fractured vertical wells. However, as the average permeability of formations being developed deteriorated, this triggered a transition to multi-stage fractured horizontal wells and not unreasonably the fracture design and techniques that were developed to move from stage to stage were designed to be fit for purpose in these much lower permeability environments. These approaches, while suitable for lower permeability and unconventional formations, are not necessarily appropriate for higher permeabilities and conventional reservoirs.

The Khazzan development in the Sultanate of Oman Block 61 includes a multi-layered, reasonable permeability, gas reservoir, which may be categorized as a tight gas reservoir. In such tight gas developments, fractured vertical wells have historically been the preferred completion design, due to favourable economics. Following an extensive appraisal programme, the development of the Barik reservoir in Block 61 was approved in February 2014, and while successful appraisal had taken place with fractured vertical wells, not unexpectedly multi-stage fractured horizontal wells were subsequently proposed as an additional incremental improvement option for development. In order to successfully achieve this, a number of standard operational practices and assumptions associated with North American unconventional horizontals needed to be challenged, adapted and in some cases stopped.

The technical journey to deliver an effective multistage well design included an assessment of the impact of assumptions and considerations that drive unconventional practice, eventually leading to the road map to success that was developed. The learning includes three key pilot horizontal wells and clearly demonstrates incremental progression that was achieved, including technical obstacles faced, engagement with a complex stress-regime and how unconventional technology has to be adapted to be fit for purpose for the formation at hand. Not a static solution, the Khazzan development continues in the initial phase with fractured vertical wells achieving a rapid learning-curve and multi-stage fractured horizontal wells being optimized further.

The experiences and outcomes from the suite of wells in this project demonstrated that multistage fracturing of horizontal wells requires careful consideration, particularly in the selection of technologies and their application. The approach adopted in this project has led to developing the field with a healthy suite of competing completion techniques that offer best-fit solutions under different scenarios, and this set of complementary options will ensure that the development economics are maximised.
A Validation Assessment of Microseismic Monitoring
Authors: Warpinski N. R. , Wolhart Steve
Published: January 2016

Microseismic monitoring of hydraulic fracturing in unconventional reservoirs is a valuable tool for delineating the effectiveness of stimulations, completions, and overall field development. Important information, such as fracture azimuth, fracture length, height growth, staging effectiveness, and many other geometric parameters, can typically be determined from good quality data sets. In addition, there are parameters now being extracted from microseismic data sets, or correlated with microseismic data, to infer other properties of the stimulation/completion system, such as stimulated reservoir volume (SRV), discrete fracture networks (DFNs), structural effects, proppant placement, permeability, fracture opening and closure, geohazards, and others. Much of the information obtained in this way is based on solid geomechanical or seismological principles, but some of it is speculative as well.

This paper reviews published data where microseismic results have been validated by experiments using some type of ground-truth or alternative measurement procedure, discusses the geomechanics and seismological mechanisms that can be reasonably considered in evaluating the likelihood of inferring given properties, and appraises the uncertainties associated with monitoring and the effect on any inferences about fracture behavior. Considerable data now exist from tiltmeters, fiber-optic sensing, tracers, pressure sensors, multi-well-pad experiments, and production interference that can be used to aid the validation assessment.

Relatively limited microseismic results have actually been validated in any consistent manner. Fracture azimuth from microseismic has been verified across a wide range of reservoir types using multiple techniques. Good validation of fracture length and height were performed in sandstones for planar fractures; fracture length and height in typical horizontal completions with multiple fractures or complexity have a lesser degree of verification. Other parameters, such as complexity, discrete fracture networks, source parameters, and SRV, have little supporting evidence to provide validation, even though they might have sound physical principles underlying their application. It is clear that microseismic monitoring would benefit from more attention to validation testing. In many cases, the data might be available but have not been used for validation purposes, or such results have not been published.
