This study conducts an in-depth rock physics analysis of the Bakken and Three Forks formations within the Williston Basin, emphasizing the role of fluid types, saturation levels, pore structure, and frequency on defining rock properties. The objective is to enhance seismic interpretation and reservoir characterization by developing rock physics templates (RPTs) for these specific formations. We explore how pore structure heterogeneity influences velocity sensitivity over a broad frequency range and varied fluid types. By integrating both Gassmann and Biot theories for fluid substitution and considering frequency-dependent velocity via Geertsma-Smit approximation, the study models fluid properties, and their interaction with the rock matrix, supported by case studies from the Bakken formation. Findings from this study reveal that gas-water systems are more frequency-dependent compared to oil-water systems. Moreover, the frequency-dependent velocity modeling revealed that combining pore structure with varying porosity and permeability levels can significantly influence the velocity-frequency relationship. The research further delineates the complex interplay between the Vp/Vs ratio and acoustic impedance, pore morphology, and fluid saturation. Notably, crack-like pores are linked with larger Vp/Vs ratios, while interparticle and vuggy pores show a more homogeneous stiffness distribution. The proposal of geology-dependent RPTs emphasize the need to consider lithological and diagenetic variations for accurate seismic interpretations.

1. INTRODUCTION

The detection of fluids through seismic reflections is a critical aspect of hydrocarbon exploration, marked by distinct indicators such as bright spots, dim outs, phase reversals, and flat spots (Smith & Gidlow, 1987; Smith & Sutherland, 1996). In seismic forward modeling, accurate fluid characterization is essential, significantly influencing Amplitude Versus Offset (AVO) interpretation (Mughal & Akhter, 2020; Smith et al., 2003). This is especially challenging for gas due to its compressibility and lower density compared to other fluids, which can lead to abnormal frequency-dependent velocity dispersion and attenuation (Malki et al., 2022a). The complexity is further heightened in carbonate reservoirs compared to siliciclastics, due to their heterogeneous pore structures, which intricately affect the velocity response to various fluid types and frequency amplitudes (Anselmetti & Eberli, 1999; Malki et al., 2023a). This sensitivity is pronounced in fractured reservoirs, where the coexistence of diverse pore structures necessitates sophisticated rock physics modeling to accurately predict P- (Vp) and S-wave (Vs) velocities under varying saturation levels and frequency ranges (Saberi, 2010).
Permeability of Serpentinized Harzburgite and its Implications on Mineral Carbon Storage
Authors: Asem Pouyan , Nguyen Anh , Bažant Zdenek P. , Matter Juerg , Labuz Joseph F.
Published: August 2024

Storage of anthropogenic CO2 as permanent carbonate minerals has emerged as a promising method for control of carbon dioxide. One approach consists of injecting low-pH, CO2-rich water in ultramafic rock that serves as a buffering medium. Accordingly, the rock dissolution will increase the solution pH such that carbonate minerals can precipitate. The permeability of the rock matrix, however, plays an important role in the buffering (dissolution) process and controls chemical reaction rates. Using X-ray diffraction spectroscopy (XRD), we analyzed the composition of the (i) vein filling material in a serpentinized harzburgite, and (ii) matrix adjacent to the vein. The XRD analysis showed that hydrated carbonates mineralized in the vein as well as the intact matrix adjacent to the surface. Permeability of the serpentinized rock matrix adjacent to the vein surface was then measured using the pulse decay approach. It is shown that a permeability on the order of 10-21 m2 and rock matrix with less than 25% serpentine minerals allowed for fixing CO2 as thermodynamically stable, hydrated carbonate minerals in the matrix.

1. INTRODUCTION

Harzburgites of the upper mantle sequence in most ophiolites are partially to fully serpentinized (O'Hanley 1996; Mevel 2003; Kelemen and Matter 2008; Boudier et al. 2010). The hydration and carbonation of facies that have undergone less serpentinization and hence are rich in olivine and pyroxene can be described by coupled dissolution-precipitation reactions:

(equation)

(equation)

Most accessible parts in ultramafic formations of the upper mantle in ophiolites, however, are pervasively serpentinized and hence contain considerable amounts of serpentine group minerals (e.g. lizardite, chrysotile, antigorite). The hydration and carbonation of serpentinized harzburgites include the dissolution of serpentine minerals (Luce 1969):

(equation)

followed by carbonation reactions where the liberated magnesium ions will bind with carbonate ions to form magnesite:

(equation)

The permeability of the rock matrix, however, plays an important role in the dissolution and buffering processes, controls chemical reaction rates and the extent of carbonation and hydration processes. Using X-ray diffraction spectroscopy (XRD), we analyzed the composition of the (i) vein filling material in a serpentinized harzburgite, and (ii) matrix adjacent to the fracture surface. The XRD analysis showed that hydrated carbonates mineralized in the vein as well as the intact matrix adjacent to the vein surface. Permeability of the serpentinized rock matrix adjacent to the vein surface was then measured using the pulse decay approach. It is shown that a permeability of the order of 10-21 m2 and rock matrix with less than 25% serpentine minerals allowed for fixing CO2 as thermodynamically stable, hydrated carbonate minerals in the matrix.
Seismic Source Characterization with Distributed Acoustic Sensing
Authors: Li Jiaxuan , Zhu Weiqiang , Biondi Ettore , Zhan Zhongwen
Published: August 2024

The emerging distributed acoustic sensing (DAS) technology can convert a pre-existing telecommunication fiber cable of tens of kilometers in length into a dense seismic array of thousands of recording channels. By measuring the laser phase change of the Rayleigh backscattering from intrinsic impurities in the fiber, a DAS system can infer the longitudinal strain or strain rate every few meters along the fiber at a frequency of hundreds of Hertz. DAS unprecedented temporal and spatial resolution makes it a promising technology for monitoring and characterizing earthquake source properties. Yet, challenges remain in leveraging this new technology due to large data volumes and the inadequacy of conventional algorithms applied to dense single-component DAS recordings. Here, we will showcase a series of research progresses in leveraging DAS for analyzing high-resolution earthquake source properties, including seismic phase picking, earthquake relocation, focal mechanism inversion, and high-resolution rupture imaging. We first introduce PhaseNet-DAS, a convolutional neural network model, for automated earthquake detection and seismic phase identification from DAS recordings. Our scalable cross-correlation framework, called CCTorch, then robustly measures differential phase traveltimes and relative polarities between picked seismic events. Furthermore, we have devised a matrix-free adjoint solver that can perform double-difference relocation using thousands of DAS channels. We have also developed a data-driven method that can reliably invert absolute first-arrival polarities on DAS, which can tightly constrain the nodal plane orientations and are critical for inverting high-resolution focal mechanisms. We have successfully applied all of these methods to several DAS arrays in California. Finally, we will showcase the back-projection rupture imaging results for the Mw6 crustal earthquake that occurred in Antelope Valley, CA in 2021. We will show that the high-resolution rupture imaging enabled by the dense DAS array can reveal the detailed underlying rupture processes and physical mechanisms at a much lower cost compared to the conventional seismic network. These successful research progresses underscore the potential of DAS as the next-generation seismic monitoring tool, that can significantly enhance and complement existing seismic networks. With the extensive existing and proposed network of onshore/offshore telecommunication fiber cables, DAS would provide critical datasets for systematically investigating the detailed seismic source properties.
Foam-Based Hydraulic Fracturing from Lab to Field Applications: A Brief Review
Authors: Abdelaal Ahmed , Aljawad Murtada Saleh , Al-Shehri Dhafer
Published: August 2024

Hydraulic fracturing, as described in petroleum literature, involves injecting fluids under high pressure to fracture formations in a controlled manner, aiming to enhance productivity and/or address near wellbore damage. Traditional water-based fracturing fluids have been widely used due to their cost-effectiveness and simplicity. However, they pose challenges such as formation water sensitivity, blockages, difficulties in transporting proppants, water availability concerns, and issues with cleaning up low-pressure reservoirs. These challenges have spurred research into alternative solutions. Foam-based fracturing technology has emerged as a promising alternative to water-based fracturing due to its minimal or zero water usage. By reducing water usage, foam fracturing minimizes near wellbore damage, lowers the risk of permeability impairment, and addresses environmental worries associated with excessive wastewater. Additionally, foam fracturing appears particularly suitable for shale gas reservoirs. This paper offers a review of foam-based fracturing fluids, delving into both lab studies and practical applications. The paper analyzes the advantages and limitations of foam fracturing compared to water fracturing. Finally, the outcomes of foam fracturing in numerous oil and gas fields are summarized. Experimental and field application results demonstrate that foam fluids have the potential to enhance hydraulic fracturing both technically and economically. The paper also identifies existing challenges and knowledge gaps, guiding future research directions in this area.

1. INTRODUCTION

Stimulation techniques were developed to enhance the productivity of wells in different ways. Technically, hydraulic fracturing can be used to bypass the damaged zones or/and to provide a high conductive pathway in very low permeability reservoirs such as shale gas (commonly less than 1 mD) (Gu & Mohanty, 2014). Economically, hydraulic fracturing increases the well productivity and makes the exploitation of unconventional reservoirs feasible. Recently, 50% of liquid petroleum and 75% of gas production in United States came from tight reservoirs (L. Wang et al., 2017). Multi-stage hydraulic fracturing combined with horizontal drilling paved the road for unconventional resources to be produced economically (Vidic et al., 2013).

Hydraulic fracturing is the most used stimulation technique for hydrocarbon reservoirs. Hydraulic fracturing creates artificial fractures in targeted reservoir (especially very low permeability) by injecting pre-designed fluids at high pressure into the formation through a well. Proppant is mixed with fracture fluids to keep the fractures open after fracture closure. The used fluids are produced after the job (clean-up) and the fractures provide a conductive pathway for the hydrocarbons.
Modeling of Thermo-Hydro-Mechanical Processes in a Bentonite Buffer Under High Temperature
Authors: Samarakoon R. A. , Zheng L.
Published: August 2024

Thermo-hydro-mechanical (THM) processes within a bentonite buffer are important for the performance of the Engineered Barrier Systems (EBS) in a deep geological repository for nuclear waste. The THM behavior of Engineered Barrier Systems (EBS) with high-level radioactive waste cannisters have been extensively studied for temperatures up to 150 °C. Recent research has been focused on investigating the behavior of the bentonite buffer at high temperatures (150 – 200 °C) which is motivated by expanding the data and knowledge base for confidence building. This study presents the ongoing HotBENT field test at the Grimsel Test Site in Switzerland. The field test consists of 4 heaters placed in series with target temperatures ranging from 175 - 200 °C in a granite tunnel. A 2-D numerical model was developed considering a cross section around Heater 1 which was maintained at 200 °C. Coupled thermal, hydrological and mechanical processes within the barrier system are modeled using the TOUGH-FLAC simulator. The model considers material zones for bentonite, concrete floor, excavation damaged zone and granitic host rock. The simulated results were compared with field test results for temperature, relative humidity and pore water pressure and the impact of thermal and hydrological parameters on the buffer performance was evaluated. The initial modeling results provide an insight into the behavior of the bentonite buffer at high temperatures.

1. INTRODUCTION

Multibarrier deep geological repositories are preferred worldwide for the disposal of high-level radioactive waste. This multibarrier system will typically consist of a metal cannister containing the waste placed within a suitable host rock. The space between the cannister and the host rock is filled with bentonite. Bentonite is chosen as a backfill material for its favorable properties including low hydraulic conductivity and high swelling potential. The Engineered Barrier System (EBS) which consists of the waste cannister and the backfill material, is subjected to elevated temperatures from radioactive decay and fluid inflow from the surrounding rock. The heat transfer through the buffer also results in thermally induced excess pore water pressures and moisture flow through diffusion. As a result of these processes, the buffer material undergoes mechanical deformation through swelling and/or shrinkage. Understanding these strongly coupled thermo-hydro-mechanical (THM) processes within the bentonite is crucial when designing a safe and efficient repository.

To bridge the gap between data and its application, the Sinopec Exploration and Production Research Institute and the Schlumberger Digital and Integration Group combined the capabilities of Sinopec's Exploration and Exploration Business Cooperation Platform (EPBP) and the Open Underground Data Universe (OSDU) for data governance in a private cloud infrastructure. To test the viability from data to application, rock mechanics parameters were derived from the direct standardization of both single well and seismic data. An exclusive application programming interface (API) was formulated, facilitating the automated data transition and from EPBP to OSDU. Consequently, the standard data is seamlessly extracted from OSDU for processing and subsequent computational applications. It underscores the potential for a consolidated approach to data standards, platforms, and service interfaces. This synergistic combination of EPBP, serving as the comprehensive data source for various data samplings, with OSDU, the vanguard for data quality assurance, emerges as a powerful tool. This integrated method performs 15% better on average in computation efficiency than standard rock mechanics parameter calculations. Impressively, the maximum error margin remains confined below 10%. It not only pioneers a novel methodology for calculating rock mechanics parameters but also lays the groundwork for future strategies in data management.

1. INTRODUCTION

Rock mechanical parameters, encompassing both elastic (e.g., Young's modulus and Poisson's ratio) and strength metrics (e.g., tensile strength and internal friction angle), serve as the nexus between geological and engineering reservoir sweet spots. These parameters are indispensable for simulating reservoir stress fields, understanding fracture dynamics, and pinpointing the engineering sweet spot (Mas Ivars et al., 2011). Their influence spans multiple disciplines, including drilling design, oil and gas development, and completion reconstruction.

Studying the determinants of rock mechanics in target formations allows for a more nuanced understanding of stress characteristics, providing a robust theoretical foundation for further exploration in the field (Zhu et al., 2020). While experimentation remains the gold standard for ascertaining rock mechanics parameters, its limitations—high costs, time consumption, and specific depth constraints—often relegate it to a calibration role.
Experimental Investigation and Modeling of Geomechanical Behavior for Methane Hydrate-Bearing Sediments
Authors: Rao M. S. , Wani S. , Kandasami R. K.
Published: August 2024

Alternative energy sources, such as methane gas hydrates, lie between renewable energy and conventional hydro-carbon fuels in terms of clean energy resources. The global abundance of methane hydrate reserves has generated interest in harnessing the energy without affecting the environment. The mechanical response of hydrate-bearing sediments depends on hydrate morphology, which exerts a profound influence on sediment behavior under various loading conditions. The present study experimentally investigates the mechanical characteristics such as stiffness, peak stress, and dilative behavior of methane hydrate-bearing specimen (MHBS), with a specific focus on the influence of densification caused by hydrate formation by comparing it with the host sand. It is observed that for MHBS, there is an increase in stiffness and a higher dilative response when compared with host sand. Additionally, this study utilizes one of the advanced critical state-based constitutive models, i.e., the Hierarchical Single-Surface Methane Hydrate (HISS-MH) model, to evaluate the model's performance in predicting the densification effect caused due to the presence of hydrates. After obtaining the model parameters, a comparison is made between the single-point integrated model predictions and experimental results. The deviatoric stress with axial strain predictions are in good agreement with the experimental results, while the dilative response is slightly underpredicted. This comparative study will offer vital insights into the mechanics of gas hydrate sediments.

1 INTRODUCTION

Methane gas hydrates are translucent crystalline compounds formed by entrapping methane gas within a cage-like structure formed by water molecules (Li et al., 2023; Wani et al., 2023a). They are predominantly found in deep marine sediments and permafrost regions, where high pressure and low temperatures facilitate stable conditions for their formation. One cubic meter of gas hydrate decomposition yields 164 cubic meters of methane gas and 0.8 cubic meters of water (Demirbas, 2010; Makogon and Omelchenko, 2013). Typically, the methane hydrate has high energy density i.e., nearly twice the carbon atoms compared to conventional fossil fuel (Wani et al., 2023b, 2022). Furthermore, methane gas hydrates are characterized by a relatively low carbon footprint, contributing less to the greenhouse gas emissions and global warming compared to conventional fossil fuels (Ma and Xu, 2021). Thus, it represents a promising source of relatively clean and efficient unconventional fossil energy. With larger reserves and wider distribution around the world, the natural gas hydrates have the potential to mitigate the global energy shortage.
Managing Risks Associated with Mining Through the Wendy Stopes at the Candelaria Open Pit Mine
Authors: Ruest Marc , Campos Jaime
Published: August 2024

Several open pit operations around the world have mined through abandoned underground mine workings by careful design and strict mining protocols. In early 2024, operations at the Candelaria Open Pit Mine in the Atacama Region of Chile also successfully developed the Phase 11 pushback benches through four large open stopes without incident. What is unique about the Candelaria scenario is the size of the open stopes in question with spans exceeding 46 m wide and Hydraulic Radii exceeding 14.5 m. The Wendy Stopes were mined following an underground, open stope method and as is the current mining practice at Candelaria, they were not filled on completion creating a mining challenge for the open pit operation.

Because of the size of the stope voids, backfilling was required by means of vertical shafts constructed through an engineered temporary crown pillar. Engineering and stability analyses for the crown pillar included both empirical and numerical design methods with results compared against a defensible acceptance criterion. The shafts were constructed following a Vertical Crater Retreat blasting sequence. State of the art monitoring systems were employed for all stages of mining to provide information on actual stope volumes, blasting performance and crown pillar behavior. Strict mining protocols and mining risk management systems were implemented during execution to ensure the safety of personnel and equipment.

The presentation provides details on all aspects of the project from the risk assessment and consultation process, engineering and stability analysis, development of operational protocols, monitoring systems, then execution and tactical risk management both on surface and underground.
The Role of Major Geological Features in the Planning, Development, and Operation of Panel Cave Mines
Authors: Campbell Ryan
Published: August 2024

Given their importance to resource and reserve estimation, major geological features are typically well-defined during the exploration stages of a project. While contact zones and regional to minescale fault systems commonly appear in planning studies, the appropriate integration of such features is more complex; particularly where safety, productivity, and capital allocation are impacted. At PT Freeport Indonesia, several large underground panel caves have experienced both positive and negative outcomes through planned and unplanned interactions with major geological features. Valuable lessons have been learned on characterization, empirical and numerical analyses, mine design, sequencing, preconditioning, and production themes. The role of major geological features in undercut front navigation and cave shaping represents areas of recent focus.
Rocks, Data, Algorithms: A Roadmap for Practical Machine Learning Adoption in Rock Engineering
Authors: Morgenroth Josephine
Published: August 2024

Recent advancements in sensor technologies, computing and data storage, and accessibility to commercial AI tools has resulted in an increase in machine learning in rock engineering research. Many researchers have been able to demonstrate data-driven algorithms that have the potential to transform rock engineering paradigms. These studies include developing ML for predicting geology with high accuracy, forecasting rock bursts in high stress environments, and decreasing the computational time needed to update complex numerical models.

Despite the potential shown in the research literature, machine learning (ML) has not yet crossed the threshold into practical use in rock engineering. This delay in adoption can be seen as an opportunity to standardize ML development in rock engineering to avoid some of the common pitfalls that can result in erroneous or nonsensical predictions, prior to widespread adoption. Namely, typical rock engineering projects suffer from three primary problems that will affect the trust rock engineers have in using ML:

1) Biased/poor quality data resulting in biased ML models

2) Insufficient data quantity resulting in unreliable ML models

3) Misunderstanding the trained ML model resulting in opaque rock engineering decisions

This presentation will highlight the source of these methodological issues by illustrating them with examples and will discuss possible strategies to avoid them when applying ML to rock engineering.
Response to Movement Within an Open-Cut Rock Face: Case Study from Ottawa Light Rail Project, Ontario, Canada
Authors: Crockford Anna M.
Published: August 2024

The Kiewit Eurovia Vinci (KEV) Partnership are currently designing and building the Ottawa Stage 2 LRT Project. The project includes a new 27 km LRT extension of the Confederation Line and includes 3.4 km of cut and cover tunnels and significant highway widening and structures scope. Brierley Associates supported KEV by providing temporary support of excavation system designs for various segments of the open-cut trench excavation through soils and rock. The rock along the project alignment consisted of layered limestone, dolostones and shale beds with predominantly subvertical and subhorizontal jointing. Based on the site investigation top of rock data, it was assumed that several faults would cross the alignment although they were not mapped. Given the rock mass conditions within the project area, a spot bolting rock support system was implemented for the vertical rock cuts in combination with regular rock face mapping and monitoring.

Along one segment of the alignment, a large sub-vertical fault was exposed below the installed soldier pile and lagging shoring. During excavation, rock conditions and monitoring data indicated a potential rock slope instability in the vicinity of the fault along one wall of the excavation. The survey, engineering and contractor teams responses were coordinated to mitigate the risks to the project and personnel. Sequence of events, response successes and lessons learned are presented.

“Não vamos esquecer”: reflexões sobre antirracismo nas organizações a partir do caso Carrefour
Authors: Musa Belmiro Dalila Maria , Barbosa de Oliveira Samuel Rubens , Moreno Fernandes Pablo
Published: August 2024

O Carrefour, rede francesa criada em 1959, está presente em mais de 30 países. No Brasil, a rede de hipermercados chegou em 1975 e já foi considerada a segunda maior empresa varejista do país. A partir de 2007, a rede sofreu pelo menos cinco processos com acusações de violência, racismo e/ou homofobia. Em 2020, na véspera do Dia da Consciência Negra, dois seguranças brancos espancaram até a morte João Alberto Silveira Freitas, homem negro, sob a acusação de discutir e gritar com uma funcionária, em uma unidade da empresa em Porto Alegre-RS. Neste mesmo ano, o movimento “Black Lives Matter” ganhou projeção global após o assassinato de George Floyd por policiais norte-americanos. A sociedade passou a condenar esse tipo de comportamento e uma série de boicotes começou a acontecer. Após a morte de João Alberto, uma onda de protestos em repúdio ao caso foi registrada em seis capitais brasileiras. O assassinato de João Alberto Silveira Freitas teve ampla repercussão nacional e a organização se viu imersa em uma crise grave sendo obrigada a responder à sociedade. Dentre as ações desenvolvidas pela organização para gerir esta crise está o site “Não Vamos Esquecer”, que se propunha a estabelecer compromissos antirracistas. Compreendemos as organizações como atores sociais em interação, produzindo e disputando sentidos com seus diferentes interlocutores (Baldissera, 2010; Lima &, Oliveira, 2014). Fundamentado na noção de publicidade antirracista (Leite, 2014; 2019), este trabalho reflete sobre as ações antirracistas nas organizações, tomando como ponto de partida as ações da rede de supermercados após o episódio de 2020. Para isso, adotamos como metodologia o estudo de caso, refletindo sobre as ações desenvolvidas pela rede de supermercados. Concluímos que as ações do Carrefour ainda estão comprometidas à manutenção do racismo como estrutura social do país, em virtude dos resultados da organização após a crise.

Nuevas tecnologías en los gabinetes de comunicación de las universidades españolas / New Communication Technologies in Spanish University Communication Departments
Authors: Busto Salinas Lorena
Published: August 2024

Las nuevas tecnologías proporcionan diversos beneficios a los profesionales de las relaciones públicas. Por una parte, facilitan la circulación de información y permiten un mayor alcance de audiencias. Por otra, ayudan a los trabajadores de esta disciplina a dar el salto de técnicos a gestores de comunicación y a incrementar su poder dentro de las organizaciones. Por todo ello, el empleo de nuevas tecnologías se ha convertido en la tendencia dominante en el ámbito de las relaciones públicas. Para comprobar si las universidades de España se encuentran dentro de esta moda, se ha enviado un cuestionario a los departamentos de comunicación de cada organización preguntándoles las herramientas de comunicación online y tecnológicas que utilizan con los diferentes públicos. Se ha detectado que las estos centros han incorporado ampliamente algunas herramientas online, como la página web, el correo electrónico, las redes sociales e intranet, e incluso muchas retransmiten acontecimientos a través de internet y ofrecen una sala de prensa virtual para los periodistas. No obstante, muy pocas hacen uso de otras herramientas más innovadoras, como wikis, Bluetooth, realidad aumentada, SMS, videoconferencias o podcasts. Divididas por naturaleza, las universidades públicas hacen un uso ligeramente mayor de más herramientas que las privadas, aunque las diferencias no son demasiado acusadas. Además, se ha verificado que no hay centros que destaquen sobradamente sobre el resto, sino que todos utilizan las nuevas tecnologías de manera parecida. En resumen, los departamentos de comunicación de las universidades de España presentan características similares en su uso de internet y nuevas tecnologías: han incorporado las más tradicionales e instauradas entre el público, pero obvian o, al menos, no hacen pleno uso de toda la amalgama de tecnologías disponibles.

The aims of the paper and presented research are to monitor trends in communication management and to evaluate specific topics that include decision-making style, leadership style, role enactment and the power of communication departments in Europe.   This paper is based on data from the European Communication Monitor (ECM) annual research, the most comprehensive analysis of communication management worldwide. The ECM is an annual research project conducted since 2007. The ECM 2011 collected quantitative data through an on-line survey from 2,209 participating professionals from 43 European countries, with representation of every European region. This paper presents original connections about previous theory and offers empirical evidences about vertical and horizontal power of communication departments into organizations. On despite of the limitations of a self-reported survey, these evidences open new directions or research on hierarchical and social dimensions of power. The aim of this paper is to deepen the understanding of the power of communication management in organizations. Concretely, the paper aims to develop knowledge and understanding about horizontal and vertical power and the relationships established between these dimensions of power and strategic roles, decision-making and leadership styles that communicators play. The paper presents original ideas by critiquing and re-focussing the literature and theory of power and leadership in organizations. The paper also presents new empirical data to support these arguments.

O propósito deste artigo é tratar sobre o papel do Instituto de Organização Racional do Trabalho (IDORT) na constituição e consolidação da atividade de relações públicas no Brasil. O IDORT, na primeira metade do século XX, teve importante atuação na difusão dos princípios que orientaram as formas de organização e gestão do trabalho em empresas no país. Dentro deste cenário, as relações públicas foram consideradas pelo IDORT uma atividade fundamental para a administração das relações de trabalho no contexto organizacional. Tendo isso em vista, o IDORT desenvolveu várias ações para legitimar as relações públicas brasileiras, sobretudo nos anos 1950 e 1960. Palavras-chave: relações públicas no Brasil, IDORT, racionalização do trabalho, comunicação nas relações de trabalho.

Com o objetivo de analisar se o estilo pessoal pode ser considerado uma ferramenta estratégica de Relações Públicas, este trabalho se originou de uma pesquisa exploratória na qual buscou-se, através de pesquisa bibliográfica, analisar a gestão de marcas pessoais a partir dos princípios das Relações Públicas e entender a função comunicativa da moda, do vestuário e do estilo pessoal. Foi possível perceber que através das Relações Públicas Pessoais, o profissional de Relações Públicas pode atuar de forma plena na gestão de marcas pessoais, aplicando as mesmas técnicas destinadas às organizações. Concluiu-se, então, que o estilo pessoal deve ser considerado uma ferramenta de Relações Públicas e que pode ser utilizado, estrategicamente e profissionalmente, para resolver os problemas e atingir os objetivos delimitados no processo de Relações Públicas.
As organizações e o público LGBT: perspectivas de atuação para o profissional de relações públicas / Organizations and the LGBT: acting prospects for public relation professional

Published: August 2024

O quadro de marginalização do público LGBT nas últimas décadas foi gradualmente substituído por uma situação de empoderamento através da atuação de grupos de ativistas e a consequente conquista de direitos em diversos âmbitos. Entretanto, a realidade ainda está longe de ser a ideal, o que pode ser constatado pela ocorrência de casos de homofobia institucional, quando organizações desrespeitam indivíduos com base no julgamento sobre as suas orientações sexuais ou identidades de gênero. Sendo assim, considerando que a atividade de Relações Públicas pode contribuir para a melhora deste cenário, este artigo possui como objetivo analisar como o profissional da área pode contribuir na gestão do relacionamento com o público LGBT nas organizações. Para concretizá-lo, realizou-se uma pesquisa bibliográfica e, em seguida, uma pesquisa documental no Centro de Referência de Direitos de LGBT e Enfrentamento à Homofobia no Estado da Paraíba para verificar os casos de homofobia institucional ocorridos na capital, João Pessoa, entre os anos de 2011 e 2013. Por fim, foi empreendida uma pesquisa de campo junto às organizações da sociedade civil que defendem este público na cidade, a fim de conhecer as suas atuações no combate a este tipo de crime. Verificamos a ocorrência de um número significativo de denúncias no período analisado, bem como a falta de conhecimento das ONGs no que diz respeito à atuação junto aos empresários visando garantir a inclusão do público LGBT nas ações das organizações locais, assim como várias possibilidades de intervenção do profissional de relações públicas para modificar este contexto.
