It can be achieved through a set of activities and decisions in which successfully drilling the oil/gas deposits is very important. Drilling is a critical step in the exploration process, and it has a high level of risk in terms of cost, timeline, safety, and project completion. The study focuses on identifying, evaluating and estimating unforeseen events that may occur during the drilling projects. The methodology acquired for this paper includes a thorough focus on the literature review which has been done. It consists of a model/theory related to risk management and the concept of risk management processes. A comprehensive project life cycle model with six stages has correlated with the drilling phases. Detailed risk management has been practised for an integrated risk portfolio for the development project. A generalized risk identification approach has been utilized to recognize possible threats. A qualitative risk assessment has been executed for the findings. Impact and probability benchmarks are categorized per the past historical well's performances and published data. Considering the importance of risk management for said projects, the study focused on the literature review that highlights the processes, procedures, and models for drilling risk management. Risks have been recognized through a rigorous and comprehensive risk identification process and have been evaluated with the qualitative risk assessment approach. The risk register for development drilling projects has been developed along with the risk matrix as per the defined criteria of risk impact and probability for drilling. Furthermore, a detailed risk breakdown structure has been formulated according to the general area categorization to enlighten the risks focused on each area of interest. Overall, the study will provide a value-added and detailed risk management approach for new ventures, which may be planned with the implementation of comprehensive drilling risks management.","PeriodicalId":50889,"journal":{"name":"Acta Montanistica Slovaca","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46989910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the first time, data were obtained on the structure of sediments' natural activity and its transformation during the altitude lowering of the riverbed lowering for 400 m. The sediment samples were taken from 12 sampling points and investigated under low-background gamma spectrometry experiments. The content of natural, in particular, daughter isotopes of the U / Th series, 40K, and artificial (137Cs) radionuclides in the sludge was controlled. They can serve as markers of the studied areas' spatial, geochemical, and anthropogenic characteristics. Standards of the content of the radionuclides - marks along the Tisza riverbed and in the vicinity of its tributary rivers have been established. Significant changes in the range of U/Th components under the lowering of the Tisza riverbed are shown, indicating geochemical anomalies in these areas. The cluster and factor analysis methods were used to study the stability of statistical indicators based on the radionuclide content in the highlands of the Tisza River and the nature of latent factors that determine their statistical equivalency and grouping conditions. The radiological research data in the sediments' samples allows for estimating the abundance of chemical elements U, Th, and K as important geochemical and geothermal characteristics of its catchment area. The importance and prospects of radiological monitoring from the origin and in all the Carpathian basins of the Tisza River are discussed, given its importance for the formation of water resources in Eastern Europe.","PeriodicalId":50889,"journal":{"name":"Acta Montanistica Slovaca","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46883555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was carried out in the Gharb plain, which belongs to the Sebou watershed in the North-West of Morocco. The goal of this study is to evaluate the contamination of the groundwater by insecticides using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and Gas Chromatography-Tandem Mass Spectrometry (GC-MS/MS) analyses. This research paper covers the analysis of 20 samples of 20 different wells for an irrigated perimeter of 250,000 ha of the surface. Further, the analyses show the presence of intense contamination caused by insecticides, which are concentrated in the southern part of the study area, where the contamination level is 50% of the water samples. This exceeds the norm of the World Health Organization (WHO) standard, which is represented in 0.5 µg/l. Furthermore, the analyses also detect the presence of 22 active ingredients of insecticides, such as malathion, methomyl alderine, dieldrin, and fenthion. Risk assessment in our studies allowed us to determine that the different RQ calculated for five insecticides (Malathion; Mythomil; chloropyrifos-ethyl; Diazinon) recorded in underground water were up to 1, which proves the intensive use of insecticide in this region and the high risk of contamination.","PeriodicalId":50889,"journal":{"name":"Acta Montanistica Slovaca","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49039421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the purpose of dendrochronological analysis, Tree-ring samples were collected using increment borers and measured by Velmax measuring system. The previous hydrological data ranging from 23 to 55 years of the same tributaries were collected from Water and Power Development Authority, Pakistan and Pakhtunkhwa Energy Development Organization (PEDO). Both dendrochronological and obtained hydrological data have been applied to reconstruct the long-term hydrological data of more than 200 years. The reconstructed hydrological data has been used for hydel power potential estimation of all studied tributaries. The current investigation presented the same pattern of flow rate and power potential in existing and reconstructed hydrological data with minor variances. The findings of this research demonstrate that reconstructed hydrological data can be obtained by using existing hydrological and dendrochronological data, and it can act as the best source to measure the expected flow rate and hydropower potential.","PeriodicalId":50889,"journal":{"name":"Acta Montanistica Slovaca","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42582403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Knowing the origin of the groundwater and the recharge area on an aquifer is essential to determine the conservation model. The purpose of this research is to determine the Denpasar Meteoric Water Line (DMWL), the recharge area, and the origin of groundwater in the unconfined aquifer of Denpasar. The determination of the number and location of samples, both rainwater samples, and groundwater samples, using a purposive sampling approach. A total of 5 samples of rainwater and 18 samples of groundwater were taken at several locations in the Denpasar area. The stable isotopes of δ18O and δ2H were carried out using laser spectrometry Picarro L2130-i. This research shows the Denpasar LMWL is δD = 8.5839 x δ18O + 19.876; from the distribution of oxygen-18 isotope, the low 18O value is dominated in the North and Northeast areas, so here this area can be delineated as the potential recharge area; and based on the isotope ratio, groundwater in the unconfined aquifer of Denpasar can be divided into three geneses groups: (a) Groundwater Genesis-A and B groups represent groundwater systems that come from direct rainfall as well as local recharge with low (depleted) to moderate δ18O and δ2H isotope ratios and groundwater groups Genesis-C, which has high (enriched) δ18O and δ2H isotope ratios, is located below the slope of the DMWL.","PeriodicalId":50889,"journal":{"name":"Acta Montanistica Slovaca","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45759260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
