Discrete Fracture Network Modelling for a Shallow Cover Road Tunnel System
Authors: Weir F. M. , Watton J. W. 
Published: January 2023

Abstract
The city of Sydney (Australia) is currently undergoing a major infrastructure construction boom, with numerous rail and road tunnels currently under construction. This paper presents DFN modelling undertaken as part of the tunnel design process for a major road tunnel system in western Sydney. The primary discontinuities controlling block formation are expected to be joints, bedding planes and seams / bedding plane shears, which were included in the DFN model. This paper presents the necessary input parameters for the modelling and derivation of these parameters, along with the model generation process.
Multiple realizations of the model were generated, with a stability analysis carried out on each. Given the complicated geometry of the tunnels in the project two representative 100 m lengths of tunnel geometries were analyzed; a wide span cavern (striking 020°) and a mined tunnel (striking 125°). The stability analyses were used to develop the unstable block volume distribution and identify the maximum likely block volume for the crown and sidewalls of the cavern. In addition, the block results were filtered relative to the proposed pattern rock bolting to assist designers with considering shotcrete loads.
Effects of Fracture Transmissivity Relationship on Repository Performance Characteristics
Authors: Smith M. , Portone T. , Swiler L. 
Published: January 2023

Abstract
When simulating flow and transport through sparsely fractured rocks in Earth’s subsurface, discrete fracture network (DFN) modeling has become the alternative approach to continuum approaches. In this work, DFNs are generated using dfnWorks, a parallelized computational suite developed by Los Alamos National Laboratory. The DFNs are then mapped to an equivalent continuous porous medium (ECPM) to allow for nuclear waste repository performance assessment simulations. To this end, reactive flow and transport calculations are performed in PFLOTRAN, a parallel multiphase flow and reactive transport code. For this study, the application problem is a crystalline repository reference case based on the Forsmark site in Sweden. When converting the fracture networks into ECPMs, fracture transmissivity is used to determine the continuum permeability field. New capabilities in dfnWorks have enabled the use of the depth-dependent correlated relationship. To understand the effect of adding the depth-dependent relationship, this study compares repository performance quantities of interest and ECPM permeabilities from the same DFN where the only change is the transmissivity relationship. It was found that although the permeabilities for the varying transmissivity relationships were significantly different, this did not strongly influence the quantities of interest.
Hydraulic Characterization of Fractures for DFN Modeling of Dam Foundation Rock Mass
Authors: Miyoshi T. , Ishibashi M. , Masumoto K. 
Published: January 2023

Abstract
One of the important requirements of foundation rock mass under dam is resistance to leakage of water. The mechanism of water leakage depends on the hydraulic properties of rock mass. When considering water leakage in fracture-dominant rock mass, the pathway of the flow is controlled by distributions and connectivity of permeable fractures. In such case, a use of discrete fracture network (DFN) models is effective to simulate the groundwater flow, as DFN approach can express fractures stochastically in three-dimension based on statistical distribution of fracture parameters. One of the key challenges when building a DFN model for dam foundation rock mass is hydraulic characterization of fractures. Hydraulic characterization in this context refers to the process of assigning hydraulic properties to the fractures generated from the geometric information. In this paper, an approach to construct a DFN model for dam foundation rock mass is proposed, with a focus on hydraulic characterization of fractures, along with a case study of foundation rock mass of an embankment dam in Japan to demonstrate the application of proposed approach.
Controlled Lab-Scale Evaluation of the Secondary Permeability Represented in a 3D Printed Discrete Fracture Network (DFN) Model

Published: January 2023

Abstract
The evaluation of fluid flow through fractured media is essential for many applications. In hard rocks, fluid flow depends on fracture aperture and connectivity, as fractures are the preferential flow paths within the rock mass. Previous research studied fluid flow, using Discrete Fracture Networks (DFN) and numerical modelling methods, with fewer lab-scale experiments. Advancements in 3D printing technology allows for generating valuable lab-scale physical models representing fractured media. In this work, a DFN model is built using the DFN software MoFrac and a 3D physical model is generated with a 3D printer. The 3D printed DFN model is fixed in an experimental set-up, which functions as a differential pressure meter by restricting airflow through a transition duct. The objectives of the experiment are to establish the behavior of the changing pressure to fluid flow through fractures. This laboratory experiment is part of an ongoing research project investigating the constructability of a Natural Heat Exchange Engineering Technology system. This system uses natural means to provide economically significant thermal regeneration capacity through a volume of rocks for ventilating mine workings. The major contribution of the lab-scale experiment is to verify whether the secondary permeability of a rockmass can admit sufficient flow.

Abstract
We present our recently developed software, FracMan/dfnWorks, which illustrates the integration of two leading software technologies - dfnWorks (LANL) and FracMan (Golder Associates Inc.) - that are widely-known for accurate Discrete Fracture Network (DFN) simulations and site characterization, respectively. The developed software brings forth advanced meshing capabilities and new approach to fracture generation procedure. The new FracMan/dfnWorks software package allows one to extend the range of physical problems that can be simulated, making DFN models relevant to a wider range of engineering problems and users.

Authors: Qin Xing , Zhao Yanlong 
Published: January 2023

Abstract
Accurately characterizing the morphology and resistivity characteristics of microfractures in shale oil reservoir is of great significance to the efficient development of shale oil. According to the scanning electron microscope (FIB-SEM) image of rock sample of the Jimusar shale oil reservoir, the pore and micro fracture structure information of shale is obtained by BP neural network segmentation method. In this paper, the refined three-dimensional digital core of shale with fracture matrix pore dual medium is reconstructed by using the improved four parameter growth method and two-dimensional fractional Brownian motion model. Finally, the effective resistivity of digital core under different fracture parameters is simulated and calculated by finite element method, and the variation law of digital core resistivity under different wettability and fracture arrangement is analyzed. The research results have theoretical significance for the construction and electrical simulation of fractured digital core.
Rock Image Segmentation Based on Improved Back Propagation Neural Network
Authors: Qin Xing , Zhao Yanlong 
Published: January 2023

Abstract
Image segmentation is an important basis for extracting the structure characteristics of the rock. In order to solve the problem that the traditional image segmentation method does not segment the rock image accurately, the genetic algorithm is used to optimize the traditional back propagation (abbreviated as BP) neural network image segmentation method. The features of the rock image domain are extracted, and the training samples are further corrected. Using the improved back propagation neural network rock image segmentation method, the rock image is segmented for three aspects: connected domain, local domain and edge domain. The calculation results compared with ImageJ software and traditional BP neural network show that under the condition of small sample size, the improved BP neural network not only can autonomously learn the whole connected structure, local domain structure and edge structure in the rock image, but improve the accuracy and speed of the BP neural network for rock image segmentation.
Discrete Fracture Network Modeling and Characterization of Deadwood and Red River Formations To Develop a SEGS, Williston Basin
Authors: Porlles J. W. , Jabbari H. 
Published: January 2023

Abstract
The Williston Basin, located in northwestern North Dakota, is one of the most prolific basins in the US, with a particular characteristic; some depth reservoirs have more than 140°C and lie between 12696 and 14000 feet in depth. Those kinds of reservoirs are cataloged as Sedimentary Enhanced Geothermal systems. Heterogeneity is an inherent component of these rocks and may be present in different forms, including mineral heterogeneity, geometrical heterogeneity, and micro-defects. This study observed the intensity and abundance of stress-induced microcracks in cores, and logs from the Deadwood and the Red River Formations. A scaled-up characterization of the Discrete Fracture Network was used implemented. Laboratory results indicate that the physical properties of rocks, such as strength, deformability, P-wave velocity, and permeability, are influenced by the intensity of microcrack.
Remaining issues of DFN – (1) Discrepancy between Geologic Fractures and Conductive Fractures
Authors: Uchida Masahiro , Yoshida Hidekazu 
Published: January 2023

Abstract
The most critical issue of the hydro-DFN-model is that only a subset of geologic fractures contribute to the groundwater flow. The authors deem that this is caused by the multiple episodes of sealing and reactivation (re-opening) of fractures. As the result of multiple episodes, groundwater flow-compartments are also formed. Flow-compartments are identified not only in the Cretaceous granodiorite in the Kamaishi mine in Japan but also in the Proterozoic granitoids of the Äspö Hard Rock Laboratory in Sweden. Understanding these processes demand the additional consideration in both site characterization and assessment. As to site characterization, identifying fracture filling minerals indicating conductive fracture such as euhedral calcite which precipitates from the present groundwater is important. Also, the pressure interference test which observes pressure responses during drilling of new holes is important to identifying flow-compartments. Sensitivity analysis and uncertainty analysis is highly recommended, since there is a practical limit for site characterization to characterize details of forementioned features for a large target rock volume. In the analysis, it is extremely important to assign reasonable constraint such as the number of conductive fracture/pathways, and the probabilistic distribution of flow rate and the maximum flow rate of the flow-paths identified by flow logging method.
A Computationally Efficient Fracturing-Production Simulator For Naturally Fractured Reservoirs
Authors: Cao M. , Sharma M. M. 
Published: January 2023

Abstract
There is a need to develop computationally efficient models for oil and gas production from naturally fractured reservoirs. In this paper, we present an efficient fracturing-production simulator by combining a boundary element method (for fracture propagation) and a Green’s function solution (for fluid flow) that eliminates the need to discretize the matrix domain. First, the model is validated against analytical solutions and then compared with a fully numerical model. A comparison of computation time shows that our simulator significantly reduces the computation cost without any significant loss in accuracy. The simulator is then applied to investigate the effect of cluster spacing and pumping schedule on production from a hydraulically fractured well in a naturally fractured reservoir. The results show an optimal cluster spacing that can maximize the contact area between fractures and reservoirs while maintaining the highest production rate. Based on the chosen optimal cluster spacing, we observe that changes in the pumping schedule can have an impact on the production rate due to changes in the fracture network pattern and contact area.

COVID-19 VACCINATION AND HOMELESSNESS: THE NEED FOR A PERSON-CENTERED INTEGRATED APPROACH
Authors: Van den Muijsenbergh Maria , Van Loenen Tessa 
Published: January 2023

Introduction: As homeless people in general suffer from poor health and are at elevated risk for COVID-19 infections they have an indication for receiving COVID-19 vaccination. However, several barriers in accessing vaccination can be identified. There is no information on the willingness of homeless people to receive the COVID-19 vaccination, nor on the experiences with the vaccination process of homeless people and professionals involved. Therefore, this qualitative study aims to provide insight into vaccination willingness among homeless people in the Netherlands, in the barriers and facilitators in accessing vaccination, and in the experiences of professionals involved in the vaccination process.
Methods: We performed semi-structured interviews with 53 homeless persons, 16 professionals involved in health care or shelter for homeless people as well as 7 public health professionals who were involved in the vaccination process for homeless people. Interviews were thematically analyzed.
Results: Homeless people experienced a lack of understandable and consistent information, which resulted in distrust and vaccination hesitancy. Mistrust in the government was common. However, approximately half of them were vaccinated at the end of the first vaccination campaign, sometimes because not being vaccinated would restrict their possibilities to access public places. Barriers to access vaccination included the complicated process and forms and difficulties accessing the vaccination venue. Especially difficult turned out to be the bureaucratic process of acquiring the Corona virus entry pass. Identified key-elements for a successful vaccination campaign for homeless people: a strong collaboration between all stakeholders, easy to understand information by trusted professionals, the possibility of vaccination at out-reach sites like homeless shelters.
Conclusion: Although the vaccination rate among homeless people in the Netherlands is estimated to be lower than among the general public, successful vaccination campaigns are possible if trusted people provide easy to understand information, all stakeholders work together and vaccination takes place at easy to reach locations.

Authors: Lourenço Carla , Esteves Dulce , Pinheiro Mariana 
Published: January 2023

Children with autism spectrum disorder (ASD) frequently present difficulties in communication, social interaction, and motor abilities. Physical activity presents several major benefits for children with and can be considered a non-pharmacological therapy to improve both motor and social skills. This chapter aims to compare motor proficiency of children with ASD and neurotypical children. Twenty Portuguese children participated in this study, half diagnosed with ASD (6.9 ± 1.97 years) and half typically developed (7 ± 1.83 years). Children’s age ranged from 4 to 10 years (6.95 ± 1.85 years), with a prevalence of males (60%). Motor proficiency was evaluated using the Bruininks-Oseretsky test of motor proficiency (BOT-2). Children with ASD scored significantly lower on different items of motor proficiency (fine manual precision, manual dexterity, coordination of the upper limbs, balance, and motor proficiency profile). We conclude that, due to the deficits found, supervised physical exercise preferentially in small groups combining children with and without ASD is highly recommended.
