Competitiveness and Impact of Government Policies on the Development of People's Arabica Coffee Plantations Partnership Pattern in Solok Regency
Authors: Tanjung Faidil , Azhari Rafnel , Erwin Erwin
Published: January 2023

This study aims to analyze the competitiveness of Arabica coffee commodities and analyze the impact of government policies on Arabica coffee commodities in Solok Regency. This research data analysis method uses the Policy Analysis Matrix (PAM). The results showed that the Arabica coffee plantation business in Solok Regency has competitiveness both in terms of competitive advantage and comparative advantage, where the value of the ratio of private costs and domestic cost ratios obtained is less than one, namely 0.48 and 0.41.  For the impact of the Arabica coffee output policy, the private price of Arabica coffee is lower than the social price. The impact of the production input policy causes the private price of tradable input to be higher than the social price, and the impact of the input-output policy causes a decrease in the producer surplus, meaning that there is no economic incentive to increase Arabica coffee production. The suggestion from this research is expected that farmers can increase the productivity of Arabica coffee than the government is expected to expand the planting area and facilitate the provision of superior seeds. The government is also expected to stabilize the selling price of Arabica coffee at the farmer level.

Published: January 2023

El tereftalato de polietileno (PET) es uno de los materiales poliméricos más utilizados en diferentes áreas como: dispositivos médicos, cables, juguetes, botellas para bebidas, entre otros. El reciclaje cuaternario tiene como objetivo aprovechar el potencial energético y calorífico del PET. El calor recuperado puede utilizarse en procesos como la fundición de metales no ferrosos. Si el PET se quema en condiciones controladas, los únicos productos de la reacción serán el agua y el dióxido de carbono, por lo tanto, esta combustión se considera como un proceso limpio. Cuando se realiza el proceso de combustión de PET, se presenta el fenómeno de radiación térmica. Este estudio investiga mediante CFD el comportamiento de la radiación en un quemador de PET, utilizando el modelo de radiación P1. La reacción de combustión se genera por la oxidación del PET con Oxigeno. Los cálculos determinaron que la temperatura media alcanzada fue de 1470 K dentro del quemador. Los perfiles de temperatura y de fracción másica, confirmaron que la combustión de PET es una combustión limpia y que es viable para utilizarse en el proceso de fundición de aluminio.

Marapu is the Sumba people's ancestral faith that believes in the power of the ancestors. The indigenous community in Central Sumba strongly embraces the traditional ceremonies related to the marapu faith. On the other hand, modernity, loaded with capitalistic values, opens up the possibility for mobilities, one of which is ideological mobility. Globalization, followed by the entrance of modern religions, creates technological shifts in the traditional community's cultural system. This research investigates the dynamics of the traditionals houses architecture in Central Sumba Regency. This research also scrutinizes the ideology and other factors underlying the shifts. The theories of ideology and hegemony are eclectically applied. This research employs a qualitative research design. Data are collected through field surveys conducted in the traditional villages. Next, village members, relevant stakeholders are also interviewed. Besides that, a literature study is conducted, followed by a descriptive-qualitative analysis. The material and functional shifts of the traditional house happen due to the rise of new ideologies, hegemony imposed by the government, and economic factors. The shifts resulting from social and cultural changes are hopefully in line with the efforts to preserve the traditions and cultural remains of the traditional villages.

Geographically, East Flores Regency covers the eastern part of Flores Island, Solor Island, and Adonara Island. This study focuses on the three old ports, namely Larantuka Port (located in the eastern part of Flores Island), Lohayong Port (located in Solor Island), and Adonara Port (located in Adonara Island). These three ports have been used as parts of maritime trade routes during colonial period. The purpose of this study is to reconstruct the function of these ports during 16th to 17th century, which were based on archaeological remains, geographical, and enviromental data. These ports are closely related to the availability of the superior commodity found in eastern Flores, namely sandalwood. The shipping lanes formed from several ports were reconstructed using maps. Most of the ports that have been researched in this region are traditional ports which has been used since Portuguese occupation of East Flores. Each port has different roles according to its location and association with supporting findings. Most of the old ports are collector ports on a local scale, except for Larantuka Port which was on an international scale. These ports are not only evidence of maritime activities, but also become nodes for unraveling the political, economic, and social aspects of civilization.

Indonesia is one of the largest archipelagic countries in the world, one of which is rich in cultural diversity in the form of values, ideas, behaviors, and cultural heritage materials from the past to the present. Cultural diversity, such as archaeological remains, which is an asset for recording the development of historical and cultural values forming the identity of the Indonesian nation's civilization, has developed massively as a tourist attraction that can generate income. As a result, it have impact on increasing economic exploitation of archaeological remains by the government, local government, industry, and society. Which inturn often consciously or not causes problems besides causing degradation of historical and cultural values, as well as the existence of these archaeological remains. For this reason, the diversity of archaeological remains as a national asset is important to managed and preserved sustainably through a sustainable tourism development approach. Scientific articles that aim to provide ideas or concept solutions are like library research carried out through qualitative descriptive analysis methods by relying on the availability of secondary data and information relevant to the topic, both in print and electronic form, from various sources. Hopefully, this article can be input into the process of solving problems and making decisions needed by the government in formulating policies for managing archaeological remains in a sustainable and integrated manner to strengthen conservation efforts for the benefit of the people's welfare.

Published: January 2023

La expresión del lenguaje oral es conocida como una habilidad que desarrollan de manera general todas las personas desde su etapa infantil, esta es considerada como una destreza lingüística relacionada con la producción del discurso oral y es fundamental para un desempeño adecuado dentro de la sociedad. El objetivo fue diseñar una estrategia basada en actividades lúdicas innovadoras para mejorar la expresión del lenguaje oral en niños del subnivel II de educación inicial en la U.E Vicente Rocafuerte del cantón Rocafuerte. La metodología fue de carácter mixto, se aplicó el método analítico–sintético, la observación científica y el método descriptivo, como población se tomó un total de 41 personas y al ser relativamente pequeña se tomó a la misma como muestra total del estudio. Como resultados se obtuvo que el nivel de expresión del lenguaje oral en los niños de la Unidad Educativa Vicente Rocafuerte es relativamente bajo ya que en su gran mayoría 60% no son capaces de articular palabras que corresponden al nivel de aprendizaje, presentando dificultades incluso en entablar conversaciones con sus compañeros y la misma docente. Se concluye que el proceso de enseñanza-aprendizaje de la expresión del lenguaje oral en niños se debe a la falta de interés de los padres de familia, sin embargo, un porcentaje de esta responsabilidad también es para los docentes ya que deben aplicar diversas estrategias metodológicas dentro del aula de clases y a su vez incentivar a los padres de familia en el cumplimiento de las tareas.
PERENCANAAN JADWAL INDUK PRODUKSI PADA PRODUK TEMPE DI RUMAH TEMPE INDONESIA
Authors: Bellinda Ayustina  , Arief Nurdini  , Ardhy Lazuardy
Published: January 2023

Rumah Tempe Indonesia is a business sector that produces various processed soybeans, one of which is tempeh with two brands, namely Tempekita and Tempe Kim's. Rumah Tempe Indonesia has also started implementing a make to stock production system in its business processes. However, until now Rumah Tempe Indonesia has not implemented a specific method to support the production system it implements. This production system can cause problems including the amount of production that does not match consumer needs, causing a shortage or excess of products which are very inefficient for the company's business continuity.

These problems can be solved through production planning using the selected aggregate planning strategy or the strategy that produces the lowest total production costs. This strategy is implemented in the preparation of a production master schedule to estimate the quantity of tempe products that must be met in the next period. In this study, two strategies were used, namely the level strategy with a production cost of 1,403,904,740.04, - and the chase strategy with a production cost of 1,404,149,544.96, -. Based on these considerations of production costs, the strategy chosen to be continued in making the master production schedule is the level strategy.

The Master Production Schedule is made based on the calculation results of the disaggregation process on the production units of each brand for each period. The amount of Tempekita and Tempe Kim's production based on the Master Production Schedule (JIP) respectively for the 1st period was 2790 and 13099 pcs, the 2nd period was 1901 and 10624 pcs, the 3rd period was 2104 and 10421 pcs, the 3rd period 4th period 3224 and 8897 pcs, 5th period 4196 and 8329 pcs, 6th period 4117 and 8004 pcs, 7th period 3735 and 8790 pcs, 8th period 4799 and 7726 pcs, 7th period 9th of 3700 and 7613 pcs, 10th period of 5409 and 7116 pcs, 11th period of 5329 and 6792 pcs, 12th period of 5070 and 7455 pcs.

Mexico’s 2013 energy reform: towards energy transition?
Authors: Iglesias Márquez Daniel , Felipe Pérez Beatriz
Published: January 2023

Mexico is an important oil producer and consumer country but its oil sector is facing many challenges. One of the most important challenges is the decrease in the oil production and reserves. In order to ensure national energy security, in 2013, the Energy Reform – a decree amending and supplementing various provisions of the Mexico’s Constitution concerning the energy policy – was enacted. This note questions whether this reform fulfills the requirements to be considered as a comprehensive reform towards the energy transition to a more sustainable energy model or whether it is a political strategy to maintain an economy dependent on hydrocarbons, obtaining economic benefits with scarce environmental concerns. The note suggests that the energy transition is eclipsed by the economic interests in obtaining maximal profits from private investment while leaving by the wayside environmental and social concerns.

Implicancias de las tecnologías informáticas en el ambiente y nuevas tendencias en el desarrollo de la informática verde como aporte al desarrollo sustentable
Authors: Martínez Adriana Norma , Porcelli Adriana Margarita
Published: January 2023

La era industrial se caracterizó por la acumulación del capital y de la propiedad física, en cambio, en la nueva era post industrial o la tercera ola, como la denomina Alvin Toffler (1979), lo estimable son las formas intangibles de poder que se presentan en paquetes de información y en activos intelectuales, por lo que el carácter físico de la economía se reduce, desmaterializándose en un mundo hiperconectado e inteligente.

Durante la mayor parte de la historia de la humanidad el ritmo de las innovaciones fue lento, sin embargo, a partir de la Segunda Guerra Mundial, el uso y desarrollo de la tecnología ha experimentado un crecimiento exponencial

Las empresas, las organizaciones y los individuos que han sabido integrar, adaptar y utilizar estas nuevas tecnologías, se están beneficiando por lo que tales herramientas pueden lograr. La revolución tecnológica no debe ser en sí misma un fin sino un medio.

Los beneficios que trae aparejada la tecnología son muchos e importantes, pero no se puede negar que también surgen nuevos problemas ligados al desarrollo tecnológico y algunos de ellos con riesgos e impactos negativos para el hombre y el ambiente. La informática y la industria en general no han ahorrado esfuerzos para desarrollarse rápidamente, pero en la mayoría de los casos a costa del deterioro ambiental.

Ya en 1970 el Papa Pablo VI se refirió a la problemática ecológica en el discurso ante la Organización de las Naciones Unidas para la Alimentación y Agricultura, conocida por sus siglas en inglés FAO (Food and Agriculture Organization), destacando que los progresos científicos más sorprendentes y el crecimiento económico más prodigioso, si no van acompañados por un auténtico progreso social y moral, se vuelven contra el hombre . En igual sentido, el Papa Juan Pablo II (1979) en su primera Encíclica (Redemptor hominis) advirtió que las personas parecen percibir del ambiente natural sólo lo que sirven a los fines de un uso y consumo

Sin embargo, las Tecnologías de Información y Comunicación (TICS) pueden ser un aliado en la lucha contra el cambio climático a través de procesos denominados Tecnologías Verdes, que se inscriben en el concepto de economía verde como contexto del desarrollo sustentable, conforme al documento final de Río + 20. El presente trabajo detallará la incidencia de la informática en los diferentes ámbitos y describirá, en términos generales, cada uno de los métodos y productos informáticos ecológicos.
DIGITALIZACIJA U SISTEMU IZVRŠENJA KRIVIČNIH SANKCIJA REPUBLIKE SRBIJE
Authors: Ilić Aleksandra , Banović Božidar
Published: January 2023

In the paper, the authors consider the use of modern technology in various aspects of the system of execution of criminal sanctions in the Republic of Serbia. On the one hand, the different forms of digitalization present in institutions for the execution of criminal sanctions are analyzed, where prison sentences and other criminal sanctions of an institutional nature are carried out, as well as the measure of detention, which is a measure to ensure the presence of the accused and the smooth conduct of criminal proceedings. In this regard, the authors analyze the differences in the use of advanced technology in the control of prisoners that exist in different prisons, taking into account the division of prisons according to the level of security. The authors start from the assumption that the most advanced type of digitalization is present in closed type prisons with special security (supermax prisons) in which prison sentences are served by persons convicted of the most serious crimes, including persons serving prison sentences in accordance with the Law on Execution of Prison Sentences for Organized Crime. On the other hand, the authors consider the issue of digitalization in the execution of non-custodial sanctions and measures with an emphasis on those sanctions and measures where the application of electronic surveillance comes into play, such as house arrest or house prison. In connection with all the mentioned aspects of digitalization in the system of execution of criminal sanctions of the Republic of Serbia, the authors analyze the available statistical and other data, all with the aim of critically analyzing the current situation and defining possible proposals for improving the situation.
The Gordian Knot of Ethno-Religious Nationalism: Unsettled National Questions and Contested Visions
Authors: Rahim Lily Zubaidah
Published: January 2023

The early twenty-first century has witnessed a rising number of global crises. These include climate change, widening income inequality, military and nuclear tensions between the major powers, repeated outbreaks of global pandemics, and an ongoing democratic recession. In particular, the deepening democratic recession has afflicted ostensibly both mature and newer democracies – contradicting theories of political development. In many countries, the political alliance between ethno- and religious nationalists has reignited assaults against democratic institutions, processes, and norms. This comparative country-case study, principally of Malaysia and the United States of America (US), explores the alliance between ethno- and religious nationalists by examining the forces and factors that have contributed to this combustible dynamic within the context of unsettled national questions, contested constitutional orders, and foundational national visions. Also examined are the narratives of fear, victimhood and privilege that have galvanised religious and ‘sons of the soil’ ethno-nationalists in resisting the building of inclusive multiracial democracies.
MASS MEDIA AND THE SUSTENANCE OF PEACE-BUILDING ROLE OF WOMEN'S AUGUST MEETING IN IGBO-LAND, NIGERIA
Authors: CHIDI AMAECHI, , OLUCHUKWU WOGU, JOSEPH
Published: January 2023

This paper investigates the mass media's role in sustaining the peace-building activities of the Women's August Meeting in Igboland with a focus on the Catholic and Anglican churches' women organisations. Specifically, it seeks to ascertain the importance of mass media as an essential instrument and to interrogate its use by the Women's August Meeting in actualising the goal of peace-building. Qualitative and quantitative research methods were adopted wherein a structured questionnaire was used to generate data from 500 respondents randomly drawn from the capitals of the five states in Igboland. Further data were generated from documentaries and published materials from libraries and the internet through literature review. Data from primary source was analysed using SPSS Version 20.0, while secondary source data was analysed using historical descriptive and analytical methods. The analysis reveals that the mass media is an inevitable instrument for Women's August Meeting peace-building activities. It further reveals that it has not been effectively employed by the Women's August Meeting to enhance its peace-building activities. The paper advocates for the application of mass media by the meeting as a viable approach to enhancing its peace-building potential.
MANIFESTATIONS OF MATRIARCHAL TENDENCIES IN THE ABAGUSII ORAL POETRY OF WESTERN KENYA
Authors: OKEMWA CHRISTOPHER , ORINA FELIX
Published: January 2023

Abagusii of Kenya, like many traditional African societies, were (are) thought to be patriarchal in their social setup. Contrary to this belief, however, there exist cultural art forms from the community which suggest a balance, if delicate, of power across gender. One such art form is oral poetry. Abagusii oral poetry is performed in all rites of passage and activities in the community such as birth, harvest, circumcision, and marriage-related ceremonies, to name but a few. When examining the oral poetry of Abagusii closely, it becomes evident that gender relations among Abagusii are much more sophisticated than generally assumed. On some occasions, matrimonial power is not only seen to exist but suggestively acknowledged as well. The study is mainly guided by the ideas of such African feminists as Oyèrónké Oyĕwùmí, Ifi Amadiume, among other gender intellectuals as Lugones [1], Gullestand (1993) Vilar [2], Shannon (1985), and Chinweizu (1990), this article examines manifestations of matriarchal power in Abagusii Oral poetry. In this regard, it explores purposively selected oral poetry of birth, courtship, and marriage. The study establishes that contrary to common assumptions, women are not only conscious of their place in the society but also serious contenders to societal influence, power, and authority. Motherhood emerges as a system that runs much deeper than most observers have been able to acknowledge. Above all, the study demonstrates that the most effective approach to uncovering "the subtleties, contradictions, and ambiguities" of gender relations in different communities is simply that of considering them within their own contexts and on their own merit.

Ayam broiler merupakan ternak penghasil daging yang sangat dibutuhkan oleh masyarakat. Salah satu permasalahan yang sering dihadapi peternak adalah mahalnya harga pakan. Tepung sawi putih merupakan salah satu limbah yang dapat dijadikan sebagai alternatif pakan karena mengandung protein sekitar 26,33% yang mampu meningkatkan produktivitas karkas ayam broiler. Penelitian ini bertujuan untuk menentukan level tepung hasil samping sawi putih yang sesuai untuk mendukung produktivitas ayam broiler. Seratus ekor ayam broiler digunakan dalam penelitian ini, pakan yang digunakan terdiri dari jagung, konsentrat, dedak, dan tepung hasil samping sawi putih (TSP). Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dan 5 ulangan dengan level P1= 0% TSP, P2= 5% TSP, P3= 10% TSP, dan P4= 15% TSP. Hasil penelitian menunjukkan tidak terdapat perbedaan pada persentase karkas broiler yang diberi pakan tepung sawi putih, tetapi terjadi peningkatan signifikan perlakuan P4 terhadap berat bagian sayap, persentase paha, dan persentase sayap, serta perlakuan P3 terhadap persentase punggung. Pemberian tepung sawi putih belum mampu meningkatkan kuantitas karkas, tetapi terbukti dapat dijadikan alternatif bahan pakan pada level 15% tanpa menurunkan produktifitas ayam broiler

Authors: Weir F. M. , Brehaut R. , Mostyn G.
Published: January 2023

This paper presents the development of a three-dimensional (3D) geotechnical model for an existing water dam in Queensland, Australia. The model incorporated data from historic construction records, recent investigation data as well as previously developed two-dimensional cross section interpretations and geological mapping records. The 3D model provided the project team and other stakeholders the ability to interrogate the ground model to an unprecedented level of detail.

The geotechnical model development was complimented by an in-depth rock mechanics assessment to investigate kinematically feasible sliding mechanisms beneath the dam spillway and abutments. This package of work included creation of a discrete fracture network model. The DFN modelling in this study was undertaken in two stages, with an initial model built to be representative of sub-horizontal fractures (with a dip of <15°), followed by a refined model, built to be representative of all fractures at the site.

The paper presents the input parameters, derivation of these parameters along with the model generation process are presented for both stages. The modelling was undertaken for both rock mass visualization and sliced on two cross-sections for input into 2D Finite Element analyses. This was particularly targeted at understanding intact rock forming bridges between laterally persistent defects within the volcanic host rock that were previously identified as a key risk to dam stability in the event of an overtopping event.

Numerical modelling of nuclear waste repositories frequently requires the representation of complex geological features and engineering in a computational mesh. Crystalline host rocks present particular challenges because simulation of THMC processes often necessitates the creation of both volumetric meshes (continuous porous media) and discrete fracture networks (fractured media), or hybrid meshes in which separate parts of the domain are represented as different media.

Here, we present near-field THMC simulations enabled by new meshing workflows for generating unstructured CPM, DFN and hybrid meshes around an illustrative facility for spent nuclear fuel. We demonstrate how the LaGriT meshing toolkit, together with DFN meshing algorithms from the combination of FracMan and dfnWorks, can be applied to create a flexible set of medium representations. In the case study, the resulting meshes represent backfilled repository tunnels using surface-conforming 3D tetrahedral cells, whilst the fractured rock sections of the model are represented by either a DFN or CPM mesh depending on the physics to be simulated.

Using the developed meshes, example THMC simulations are undertaken in PFLOTRAN and FracMan. The results demonstrate how the integrated workflow can be used to create high quality, realistic model inputs which result in improved convergence and accuracy in numerical simulations.
Processing and Conversion of Raw Point-Cloud Laser Measurements and Auxiliary Data of Rough-Surfaced Fractures To Generate Corresponding Fracture Aperture Fields

Published: January 2023

Understanding subsurface flow mechanisms in fractured rock is essential for subsurface infrastructure industries and geoscientific research. It is common to explore this using numerical modelling, however recently there are studies now replicating fractures by making use of 3D printing technologies. In order to produce a fracture replica, data from a real rock surface must be provided and an aperture field obtained. This data can be used for both 3D printing and numerical modelling and has the advantage of providing a direct correspondence between the 3D printed and numerical aperture field. In this study scans of the upper and lower surface of four 100 mm by 70 mm fracture cases were provided as point-cloud data. Pressure film data was also provided showing the pressure distribution across the aperture field at 5MPa of normal load.

The scanning method results in an irregular mesh when looking for instance on the XY coordinate plane. This means the nodes of the upper and lower surface of the same fracture will not coincide. Due to this, the surface data is linearly interpolated onto a regular grid with a resolution of 0.1mm in order to easily obtain the aperture field. Issues arise from the vertical referencing of the upper and lower surface scans, resulting in unrealistic aperture field distributions. To correct this the lower surface is translated relative to the upper surface to improve alignment and reduce inaccurate negative values. However, this was insufficient to fully correct the aperture field, so the pressure film is used as a reference to vertically shift the upper surface until a visual best fit aperture field distribution is achieved. Once the aperture is obtained it can be used for numerical modelling and 3D printing. This study provides an example methodology for converting raw point-cloud data to a meaningful data set for representation of fracture apertures, as well as highlighting limitations and factors to consider during the process.

The Oued Mya Basin is one of the most oil-productive basins in Algeria. The wells’ productivity in these low permeability Ordovician reservoirs is attributed to the interconnected fracture networks. The faults and fractures characterization were carried out on two approaches. The first approach consists of the analysis of faults picked from 3D seismic volume and the second comprises the analysis of the sub seismic faults digitized from different seismic attributes and wellbore imagery analysis. Two trends of faults are highlighted and separated by a syncline oriented in the same direction. This architecture seems to be the result of several tectonic events, with a complex fault system-oriented NNE-SSW and interspersed with another of the sub-orthogonal fault system. The two orthogonal fault systems compartmentalize the region into horsts and grabens. The different fracture sets are connected and can contribute significantly to the productivity of this reservoir. The SHmax is homogeneous in the region, it is oriented NW-SE with a reorientation NE-SW to NNE-SSW at the wells of Berkaoui field and Guellala field, indicating diagram concordant with a transcendent dextral strike-slip fault. Wells showing the presence of trace of hydrocarbons can be stimulated by targeting fracture parallel to the maximum horizontal stress to improve the reservoir fluid flow.
Quantifying Connectivity of Fracture Networks: A Lacunarity Approach
Authors: Roy Ankur , Lahiri Sivaji
Published: January 2023

Connectivity estimated by simply considering the relative number of nodes in fracture networks, i.e., cross-cutting (X), abutting (Y), and isolated (I), without regard to their spatial distributions, is often not a unique identifier of fracture geometry. This research proposes a modified, lacunarity based estimate of connectivity which considers both the spatial distribution of such nodes in a network and also their abundance. We compare three pairs of natural fracture maps from different sources, each pair with the same connectivity but very different visual appearances. A study of the flow properties of these maps using a streamline simulator and invoking the fracture continuum model showed that pairs of maps with same connectivity but different visual appearances yield distinct recovery curves and time-of-flight (TOF) plots. A MATLAB toolbox, FracPaQ, is used to identify and spatially map the three different X, Y and I-nodes in fracture networks. The spatial clustering of nodes that facilitate conductivity (X, Y) and those that hinder flow (I), are calculated separately by implementing a log-transformed lacunarity summed over a range of scales as:  and  respectively. The values are then used for generating a multiplier, κ =  / , which is incorporated into a new connectivity index, L-connectivity. The results show that pairs of fracture maps that have the same apparent connectivity, but with differences in visual appearances and hence, flow properties, can be distinguished based on this new lacunarity-based connectivity index. This parameter may therefore, prove to be a unique identifier of the connectivity of fracture networks. L-connectivity may be potentially utilized for estimating the network connectivity and, as a first pass for evaluating fracture network geometry by modelers and engineers who deal in fractured petroleum reservoirs and aquifers.
Natural and Hydraulic Fracture Interaction: A Proxy for Tracking Flow Trajectory
Authors: Sarmiento S. , Makedonska N.
Published: January 2023

In this work, dfnWorks simulation tool is used to track the efficiency of hydraulic fracture stages across a hypothetical multi-stage hydraulic fracture well connected to a natural fracture network under low porosity and permeability typical of unconventional shale reservoirs. The evaluation of the influence of hydraulic fractures on the fluid flow trajectories and velocities in a natural fractured reservoir was weighted by the modeled connectivity with the natural fractures (DFN) and by the use of hydraulic fracture stage pressures. Under low natural fracture intensities is connectivity the factor that matters more in fluid flow towards the well; conversely, under high fracture intensities and the resulting high connectivity, fluid flows towards the well is more influenced by low-pressure stages or stages with highest pressure gradient between the boundary faces and the horizontal well.
Using DFN Logic in Open Pit Stability Analysis Applications for Calibration and Predictive Calculation Including Defined Persistence Discontinuities

Published: January 2023

In open pit stability analyses, numerical modeling helps to evaluate failure modes related to the interaction between discontinuities and the rock mass. In particular, numerical models that integrate discrete fracture networks (DFNs) are a relevant tool for detecting slope failure mechanisms, especially when failure involves slippage along geological structures. Traditionally, the focus of such analyses is stochastic in nature. However, a deterministic approach to open pit modeling can be adopted using DFN as a discontinuity integration logic with defined persistence based on field mapping.

This article presents a stability analysis of a "deterministic" type approach which implements the DFN logic incorporated in discrete element software, which would allow for the representation of discontinuities of variable persistence. The methodology has been validated through its application in numerical open pit models aimed at calibrating instabilities and evaluating predictive design conditions, whose results have been satisfactory, and representative of the instability conditions observed in situ.
