Published: January 2025

<p class="Abstract">The term<em> good-looking</em> is still used in the labor recruitment process in recent years. Especially in the recruitment of bank employees in Indonesia. Bank employees in Indonesia often get the stereotype that "bank staff must be beautiful”. So, this study describes the representation of<em> good-looking</em> bank employees in Indonesia. From this representation, this study also explains that the term <em>good-looking</em> is a term that practices beauty standards in society. This study used qualitative methods and took the data from<em> informal conversations</em> with several informants. In this study, researchers applied the theory of post-feminism, namely<em> beauty myth</em>, and also used Foucault's theory of power relations. The results of this study show that some banking agencies do facilitate their employees in caring for and maintaining physical appearance. It also proves that a <em>good-looking</em> bank employee is according to social beauty standards (ideal height and weight, <em>langsat </em>skin, <em>makeup</em>, and others). This proves that the standard practice of beauty in women is still thriving in society, even in a job or career, not in the entertainment field.</p><p> </p>

2024 Enhanced Geothermal System Hydraulic Fracturing Campaign at Utah FORGE

Published: January 2025

Abstract
The Utah FORGE (Frontier Observatory for Research in Geothermal Energy) is a U.S. Department of Energy-sponsored field laboratory for demonstrating and promoting the feasibility of hydraulically fracturing thermally conductive granite (or similar) formations to create an Enhanced Geothermal System (EGS). One embodiment of an EGS, as adopted at FORGE, is to drill injection and production wells and interconnect them with hydraulic fracturing to form a subsurface heat exchange system. Three small fracturing treatments in the injection well were carried out in April 2022. In April 2024, eight fracturing stages were pumped in the injection well, and four fracturing stages were pumped in a vertically offset but parallel, sub-horizontal production well. The static bottomhole temperature is 430°F. The stages in the production well were perforated based on fracture intersections or proximity detected by fiber optics that had been previously cemented on the outside of the casing string in that well.
To establish optimal procedures for treating granitic or similar reservoirs, the eight stages incorporated several variables to test, at least on a preliminary basis. These variables included stage volume, proppant placement, testing an ultralightweight proppant (ULWP), fluids – slickwater versus crosslinked carboxymethyl hydroxypropyl guar (XL CMHPG), and the number of perforation clusters.
Most stages treated well, some verging on screening out. In two stages, proppant was not pumped as the treating pressure reached the maximum allowable surface pressure before achieving a pump rate sufficient to successfully carry proppant. This suggested unexpected geologic differences in this granitoid batholith. Regardless, all other stages treated well and are described. Silica sand was chosen for the proppant since the FORGE wells are not going to be used for commercial purposes.
This is one of the few times that wells have been intentionally interconnected successfully. There was some success at the Fenton Hill project in the 1980s and Fervo Energy successfully interconnected wells in a geothermal play in Nevada. Fervo Energy has also started development of a new EGS project offsetting the Utah FORGE acreage. The importance of fiber optics is documented, along with the role of stimulating both wells and characteristic treating records for the production well. A nine-hour circulation test performed immediately after stimulation treatments confirmed significant hydraulic connectivity between the two wells. A successful longer-term circulation test conducted three months after the stimulation program is also described. Efficiency built to about 90% before a planned shutdown and flowing temperature tracked increasing flow rate from the production well – reaching a maximum of 385°F.
Determining a Minimum Polymer Concentration to Optimize Dynamic Proppant Suspension and Transport at a Particular Shear Rate and Proppant Concentration
Authors: McGoran C. , Stephens C. 
Published: January 2025

Abstract
For hydraulic fracturing treatments, propped area and fracture efficiency are dependent on the proficiency of proppant transport into the fracture aperture. Resultant fracture conductivity is dependent on how well proppant can be distributed throughout the fracture. Typically, two mechanisms are present that can assist with proppant transport: inertial effects and rheological effects. Within the wellbore, at high Reynolds numbers, inertial effects are the dominant mechanism for proppant transport. Within the reservoir, the rheological properties of the fluid govern proppant diffusion, along with fracture geometry and fluid leak off.
Building on this foundation, our research introduces a new method for quantifying DPS in hydraulic fracturing, enhancing traditional techniques with a modified rotational coaxial cylinder viscometer and image processing technology to precisely measure proppant settling rates under specific shear conditions. The proposed methodology provides a novel empirical method for quantifying DPS for bulk proppant samples at controlled shear rates. Utilizing high-speed cameras with high-resolution image processing techniques, we delve into proppant transport phenomena, focusing on the interplay between fluid dynamics, proppant characteristics, and chemical properties. This approach aims to optimize proppant transport efficiency, ensuring friction reducers (FR's) are selected and designed with a comprehensive understanding of their performance. By highlighting the significance of inertial and rheological effects across various shear rates and the impact of fracture geometry on proppant transport, our work seeks to enhance proppant efficiency and resulting conductivity. Ultimately, our integrated methodology offers valuable insights into proppant behavior under varying conditions and the pivotal role of determining a minimum polymer concentration to measure proppant suspension and efficiency.
The methodology allows for the inclusion of high concentrations of proppant as an alternative to single particles, static settling tests that are often modeled utilizing Stoke's law for settling velocity. The rotational speed of the rheometer's external concentric cylinder can be adjusted to emulate reservoir shear conditions. Settling rates are continuously acquired, and the data can be analyzed temporally to study the shear effects on the fluid. The cross-sectional area of the fluid column that contains a certain threshold of proppant is calculated.
Hydraulic Fracturing Design in Geothermal Wells: A Utah FORGE Case Study
Authors: Liu Qianjun , Cao Meng , Ou Yuhao , Sharma Mukul 
Published: January 2025

Abstract
Unlike traditional hydraulic fracture design, fractures in geothermal injection wells must intersect production wells. The primary objective of this paper is to design perforation clusters and fractures in geothermal injection and production wells to optimize inter-well connectivity and promote the formation of complex fracture networks. A secondary objective is to evaluate the role of natural fractures on the geometry of the fracture network created.
A stochastic discrete fracture network (DFN) was generated to represent natural fractures at the Utah FORGE site based on a detailed geological characterization of the site. The propagation of multiple hydraulic fractures was modeled using a displacement discontinuity method (DDM) to account for the interaction of the hydraulic fractures with natural fractures. We evaluated key parameters that control the fracture network geometry: cluster design (number of clusters and spacing), perforation design (number in each cluster), pumping schedule, fluid rheology and proppant loading. The number of fractures that intersect the production well was estimated based on the simulation results. The optimum design was one in which the largest proportion of fractures intersected the injection well.
Perforation and fracture designs in geothermal wells were shown to be quite different than in oil and gas wells. Our results show that stress shadow effects limit the number of fractures intersecting the production well. Fractures either grow tall or grow laterally to avoid the stress shadow of adjacent fractures. Among the perforation designs tested, extreme limited entry perforation designs not only made the fluid and proppant distribution more uniform but also resulted in smaller stress shadow effects. We showed that an optimum cluster spacing is needed to minimize stress shadow effects but also maximize the energy recovery from multiple fractures. Tapered perforation designs improved fracture uniformity and enhanced inter-well connectivity. A reduced ramp-up rate resulted in a more uniform fracture length and height distribution. Alternate stage fracturing (the Texas-Two-Step method) significantly improved inter-well connectivity. Results from fiber optic data used for monitoring real-time fracture propagation were consistent with the simulation results and verified the optimized hydraulic fracturing designs.
We show for the first time that pumping schedules, perforation cluster design, cluster spacing, and fracture sequencing can play a crucial role in ensuring good connectivity between EGS well pairs. We also show how fracture designs in geothermal wells can be optimized. Observations from fiber optic measurements confirm many of the design recommendations.
Achieving Uniform Proppant Distribution in Horizontal Wellbore Clusters Using CFD Modeling

Published: January 2025

Abstract
Slickwater multi-stage hydraulic fracturing is one of the most effective technologies for stimulating unconventional reservoirs. However, achieving uniform proppant distribution between perforation clusters in slickwater fluids remains a significant challenge due to the low viscosities. Several studies have focused on proppant placement in the wellbore, but relatively few have focused on the variations in proppant distribution between sealed and leaking plugs. In this study, a computational fluid dynamic (CFD) model was developed to investigate uniform proppant distribution between the perforation clusters without fluid leakage from the plug.
The CFD model was initially developed using a laboratory-scale geometry and validated against experimental data of the proppant distribution in a horizontal wellbore. The laboratory and base model consist of a 1.5-in diameter, 30 ft long wellbore with three perforation clusters spaced 7 ft apart. Each cluster has 4 shots per foot (SPF) perforations with a 0.25-in diameter and a 90º phasing. A small valve was placed at the end of the wellbore section acting as a sealed plug. Subsequently, the model was scaled up to a 51 ft long wellbore with six perforation clusters of identical diameters and spacing. The initial model was used to investigate the effects of various injection parameters on proppant distribution, whereas this scaled-up model was used to evaluate the effect of perforation orientation and configuration on the proppant distribution.
Both lab and CFD model results show that closing the back valve without leakage affects the amount of the proppant placement in the last two toe clusters compared to those with leakage. This leads to less proppant settling in the toe cluster and more proppant settling in the preceding cluster. The leaking plug model showed all bottom perforations receive significantly more proppant, while the sealed plug model showed the last cluster's bottom perforation receives less proppant due to a plugging effect. The model results show that higher proppant density and larger particle sizes result in non-uniform proppant distribution with less proppant settling in the toe cluster. Higher proppant concentrations resulted in non-uniform proppant distribution, with more proppants being transported towards the toe clusters.
The scaled-up model results show that the perforation orientation significantly impacts proppant distribution. Changing the perforation phasing from 90º to 70º results in a uniform proppant distribution in a 2 SPF case. Additionally, a 4 SPF top perforation configuration with a 0° phasing displayed different proppant transport and distribution phenomena compared to a 90º phasing.
