In addition, a rose diagram portraying the distribution of mineral locations was compared to the distribution and trends of faults using fractal and fry analyses, showing that the spatial pattern of porphyry copper deposits is closely linked to NW- and E-trending faults. In other words, the aforementioned structural trends were plausibly the chief geographical directions controlling the mineralization. The results of this study suggest that NW- and E-trending faults have plausibly operated as corridors for the transportation of ore-bearing fluids.","PeriodicalId":12714,"journal":{"name":"Geosystem Engineering","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12269328.2019.1700171","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42197600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A grade block model was built using the optimal parameters of variograms and with the help of kriging estimator. Then, by using different methods of estimating the block model uncertainty including kriging estimation variance, block error estimation, kriging efficiency and slope of regression, classification of mineral reserves was carried out in accordance with the JORC standard code. Based on different cut-off grades, the tonnage and average grade were calculated and plotted. An innovative quantitative method based on the distribution function of the mentioned parameters and the fractal pattern of separation of populations was used for the classification of mineral reserves.

While it is important to address the value of the flexibility in the contracts, the literature on the contract valuation in uranium markets is scant. In this paper, we evaluate the quantity flexibility in the context of Korean long-term uranium contracts. Specifically, we adapt the least squares Monte Carlo method to simulate the contract value while incorporating the characteristics of option structure and the dynamics of uranium prices. Our simulation results show that the quantity flexibility can play an important role in uranium long-term contracts. The results are also robust to the choice of basis functions, which implies that the method we applied in this paper could provide correct valuation of long-term contracts. Moreover, our results provide some policy implications related to first, the KHNP’s strategy to mix of long-term and spot-market uranium contracts, and second, correct valuation of contract parameters when negotiations take place.","PeriodicalId":12714,"journal":{"name":"Geosystem Engineering","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12269328.2019.1683081","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41648985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Convergence technology for enhanced oil recovery (EOR) has recently been drawing attention as an upcoming technology to evolve toward similar performance and synergies. As one of the convergence technologies, PF utilizing low-salinity water is applied to improve oil recovery. In this study, an attempt is made to identify its mechanisms and to understand the low-salinity effects on PF in complex oil fields. Injection scenarios are made up to identify the efficiency of combining LSWF and PF (LSWF-PF), and sensitivity analysis is performed on the design parameters, such as slug size, salt concentration, and polymer viscosity, which are considered to be the most influential parameters. The results indicate that the efficiency of PF is significantly improved by using low-salinity water as the polymer solvent and the slug size of low-salinity water should be preferentially considered for the successful application of LSWF-PF in high-salinity reservoirs. Therefore, it is believed that a criterion can be set up to decide the design parameters of LSWF-PF, which can improve synergy effects in EOR processes.","PeriodicalId":12714,"journal":{"name":"Geosystem Engineering","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12269328.2020.1732839","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44998384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the experiments were conducted to determine the microscopic mechanisms and effects of water plugging, profile control, and ‘water plugging + profile control’. Initially, the starch graft copolymer and polymer gel used showed only slight changes in viscosity. However, within 12 h, the viscosities exceeded 100,000 mPa·s, which indicated that the two agents had good plugging effects. When the plugging agent was starch graft copolymer, the oil recovery with water plugging was 2% and 0.8% higher than the values for profile control with polymer gel on a heterogeneous core and parallel core, respectively. The recoveries with the ‘water plugging + profile control’ combination for the heterogeneous core and parallel core were 25.9% and 25.5%, respectively, which showed the superior enhanced oil recovery. The mechanism research showed that when the reservoir entered the middle and high water-cut development stages, the residual oil was mainly distributed in the middle- and low-permeability layers near the oil well. Thus, water plugging provided a greater increase in oil recovery. Under the actual demands of the Bohai oilfield, it would be better to adopt a combined water plugging and profile control operation.","PeriodicalId":12714,"journal":{"name":"Geosystem Engineering","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12269328.2020.1732838","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43402316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of FTIR and XRD analysis confirm the presence of synthesized Ag nanoparticles on the surface of MWCNTs. TEM results reveal that Ag nanoparticles can successfully introduce on the surface of oxidized MWCNTs. The results of the analysis of variance (ANOVA) confirm that both models are significant for viscosity prediction of nanofluids. Meanwhile, the results reveal that the temperature (40 and 70) and weight fraction (0.125 and 0.5) have a significant effect on the viscosity of MWAg-1 nanofluids. In addition, the results confirmed that the importance of temperature is more than the concentration of MWAg-1. The contribution percent of temperature and weight fraction reveals that the contribution of weight fraction (44.08) is higher than that of temperature (37.71°C) at the proposed model.

The low effective or ineffective circulation of abundant injecting water in high permeability layer, low producing degree of low permeability layer and large polymer volume have influenced the sweep efficiency and oil recovery of polymer flooding. In view of these questions, the alternative injection method of various viscosity polymer slugs is studied. This paper explains the theory of enhanced oil recovery of multi-slug polymer alternative injection. The experiment results show that the alternative injection of high and low viscosity polymer slugs has a better effect than single slug polymer flooding. The mobility differences between high-low permeability layers can be effectively reduced. For a multi-layer heterogeneous reservoir, there is an optimal alternative cycle. Reasonable slug size can not only inhibit dominant channel forming in high permeability layer but also can effectively produce low permeability layer and control profile inversion to a certain extent. This provides a technical support for studying the controlling methods of profile inversion.","PeriodicalId":12714,"journal":{"name":"Geosystem Engineering","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2020-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12269328.2020.1713910","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47251214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimal batch-scale extraction conditions were determined for the preparation of feed for extraction column (D2EHPA 0.08 mol/L; pH~8).

Three responses studied were slip velocity, dispersed phase holdup, and extraction efficiency. The higher value of extraction efficiency for lanthanum extraction shows the main effect of agitation intensity on the dispersed phase holdup, slip velocity, and rate of mass transfer. The optimum conditions for extraction efficiency equal 98.5% were obtained at a rotation speed equal to 7.75 1/s, and phase flow rates equal to 1.25 × 10−5 m3/s.

Hence, an attempt was made to develop the technology for pyrophyllite to produce a powder that meets these requirements through understanding the crushing characteristics. Roasting of pyrophyllite at 1150 °C resulted in the alternation of raw pyrophyllite and led to differences in the crushing characteristics. Crushing of the roasted pyrophyllite produced a powder with a reduction in the amount of the fine particles (−45 μm) compared to the powder of the raw pyrophyllite under identical crushing condition. This difference is attributed to the alternation of the raw pyrophyllite after the roasting process, as confirmed by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM) results as well as by the amount of water adsorption. The melting characteristics of the raw and roasted pyrophyllite samples were investigated for application to the aluminumborosilicate glass production.
