Published: November 2022

Abstract
Supercritical carbon dioxide fracturing technology, as the main representative of water free fracturing technology, has unique advantages and broad application prospects in the development of shale oil and gas reservoirs. Supercritical carbon dioxide fracturing technology has low damage to the reservoir, no residue, and the fracturing fluid can flow back quickly, which is particularly suitable for the stimulation of shale oil reservoirs. It also injects carbon dioxide into the ground to reduce environmental pressure. However, as a new fracturing technology, the research on the fluid loss mechanism of supercritical carbon dioxide fracturing is not perfect. For this reason, based on the fluid solid coupling of porous media, this paper establishes the fluid loss model of supercritical carbon dioxide fracturing fluid in shale reservoir. The research results show that supercritical carbon dioxide fracturing fluid is greatly affected by temperature and pressure. The greater the viscosity of fracturing fluid during injection, the greater the resistance of fluid in the formation, and the slower the fluid loss rate. contributions of the work.

Introduction
With the progress of oil and gas field development technology, the development of low permeability and tight shale oil and gas resources has been paid more and more attention(Holditch, 2013). The decision-making power of the future energy market mainly depends on the resource potential and development degree of unconventional oil and gas. Nowadays, unconventional oil and gas resources development technologies and transformation measures represented by shale oil and gas are gradually maturing(Cui, 2019a , Cui, 2019b). Among these technologies, carbon dioxide fracturing technology has unique advantages in the stimulation and development of shale oil and gas reservoirs(Monjezi et al., 2020 , Rod et al., 2020 , Nianyin et al., 2021b , Nianyin et al., 2021a), including that the fracturing fluid does not contain water and has strong applicability to water sensitive formations(Liu et al., 2014).

Abstract
An in-depth description of the objectives of rich gas cyclic huff 'n' puff in the Three Forks of the Williston Basin, as well as the design, field operations, production, pressure, and other surveillance results, is provided in this case study. To summarize, the overall purpose of the enhanced oil recovery (EOR) and CO2 storage, a case study, was to discover important performance indicators of cyclic gas injection, which would then be used to construct a commercial field scale EOR method. To achieve these objectives, a fully designed well in the Three Forks tight oil play was tested vertically and laterally for the potential to confine gas inside the target intervals and create pressure to induce a miscible displacement process. In this paper, a detailed reservoir model was built to investigate the CO2 huff-and-puff process for enhancing oil recovery (EOR), and to understand the impact of different parameters on the CO2 EOR performance in different scenarios. The model includes an area of well-characterized Three Forks formation and fracture characteristics with actual production data from the field for accurate history matching and forecasts. The effects of cycle number, injection and soaking period, permeability, reservoir bottom hole pressure, and CO2 molecular diffusion are investigated to optimize the reservoir's CO2 EOR performance. The findings suggest that CO2 diffusion is essential in enhancing oil recovery from tight oil reservoirs as the recovery factor (RF) without diffusion was 12%, including the diffusion coefficient the RF increased by 4%. Also, the bottom hole pressure significantly impacts the recovery factory. Furthermore, the CO2 huff-n-puff technique is more beneficial in tight oil formations with high permeability and more CO2 injected in a short soaking period. Significant design and operational efficiencies were discovered during this well simulation for gas injection test in the Three Forks play that will benefit an economically feasible fieldscale project. For example, the schedule of injection and soaking period permitted gas injection operations to be carried out without modifying wells' operation pressure. Cycling in a short soaking time makes it possible to perform injection/production conversions at the lowest possible cost. It is also possible that including the diffusion coefficient in the simulation will have better gas injection conformity across the horizontal completed intervals.
Geological Modeling Along Tunnel Projects Using Machine Learning Techniques

Abstract
Tunnels offer considerable benefits over other alternative forms of transportation infrastructure. For example, in contrast to highways, tunnels ensure unobstructed land above remains available for all forms of land-use that can present notable economic, social, and environmental advantages. This feature is important in highly urbanized areas where usable land is scarce and acquiring land can put high financial pressure on available budgets. Tunnelling uncertainty is the main contributor to cost overruns which are mainly due to geological uncertainity. Therefore, accurate prediction of geological characteristics can lead to higher efficiency of tunnelling projects and prevent any cost or time overruns. In this paper, a random forest (RF) approach is utilized to model underground lithology using 65 boreholes along a tunnel project. In order to acquire best hyper parameters for the RF model a random search optimization algorithm is used. Also, different intervals along the boreholes are used to extract the lithology to find the sensitivity of the model to different interval length. The results show that the proposed model can predict the lithology with 86 percent accuracy. The model was successful in prediction of lithology type and their order along the boreholes in a case study example.

Introduction
Tunnels offer considerable benefits over other alternative forms of transportation infrastructure in terms of land-use and planning. This feature allows for greater flexibility in use of lands in highly urbanized areas where usable land is scarce and acquiring land can put high financial pressure on available budgets. Tunnelling uncertainty is the main contributor to cost over runs the which is mainly due to geological uncertainity. Therefore, accurate prediction of geological characteristics can lead to higher efficiency of tunnelling projects and prevent any cost or time overruns (Yan-lin et al. 2011; Hossin and Sulaiman 2015; Zhang and Zhu 2018).

Abstract
The challenge of drilling in relatively frontier area with active collision margin typical of Eastern Indonesian foreland basins requires an integrated geomechanics analysis to identify drilling hazards, improve well design, and optimize drilling cost. Earlier batch drilling located in the northern part of the Senoro Field targeting on pinnacle carbonates did not encounter significant drilling issue, except for minor tight spots and losses in the carbonate reservoir section. However, later drilling batch in the southern part of the field which associated with large strike-slip faulted platform carbonates encountered significant drilling issues related with pack-off, tight hole, and stuck pipes while tripping in 5000 ft long 12-¼” hole section within the Kintom Formation overburden, despite of initial high penetration rate. In order to identify and prevent similar drilling issues, 1D Wellbore Stability Analysis (WBS) workflow conducted to solve the vertical stress and pore pressure, elastic rock properties, horizontal stresses around the wellbore. Fault stability analysis (FSA) conducted to understand the possibility of fault reactivation due to drilling activity. In addition, lessons-learned from drilling experience and best-practice improvement in offset well is also evaluated to validate with the geomechanics analysis results.

Introduction

ABSTRACT
Dengue Hemorrhagic Fever (DHF) is one of the public health important viral disease because. The location of the village is close to the Mount Halimun Salak National Park, the plants vegetation is relatively dense and high rainfall each year. High rainfall in the village can cause containers outside the house to fill with rainwater, this will provide a breeding ground for mosquito growth. The environment around the house where there is still plant vegetation that can function as a habitat and resting place for mosquitoes, especially mosquitoes of the genus Aedes. This community service aims to increase community knowledge about dengue disease in order to prevent the spread of dengue disease. The method used is counseling and larval surveis directly to residents' homes. The results of community service showed that Aedes aegypti mosquito larvae were found in 8 residents' houses. The mosquito larvae of Ae. aegypti which is a vector of dengue disease indicates that it is still possible for the spread of dengue disease. For this reason, a regular and continuous mosquito larvae inspection program is needed.

Este trabalho pretende refletir sobre a leitura da obra de Clarice Lispector (1920-1977) pelo viés ontológico-existencialista, proposto por Alfredo Bosi (1936-2021) em História Concisa da Literatura Brasileira. Nesse sentido, nossa proposta é compreender os comentários sobre a ficção clariciana na história de sua recepção. Assim, por vezes, compararemos com os argumentos críticos da recepção atual da literatura de Lispector. Nossa discussão, em suma, tem como objetivo mostrar como a visão de Bosi dialoga sobremaneira com o tempo de uma leitura que considerou o existencialismo como instrumental de interpretação das narrativas dessa escritora.
