To solve the problem that it is difficult to identify carbonate low resistivity pays(LRPs) by conventional logging methods in the Rub Al Khali Basin, the Middle East, the variation of fluid distribution and rock conductivity during displacement were analyzed by displacement resistivity experiments simulating the process of reservoir formation and production, together with the data from thin sections, mercury injection and nuclear magnetic resonance experiments. In combination with geological understandings, the genetic mechanisms of LRPs were revealed, then the saturation interpretation model was selected, the variation laws and distribution range of the model parameters were defined, and finally an updated comprehensive saturation interpretation technique for the LRPs has been proposed. In the study area, the LRPs have resistivity values of less than 1 Ω·m, similar to or even slightly lower than that of the water layers. Geological research reveals that the LRPs were developed in low-energy depositional environment and their reservoir spaces are controlled by micro-scale pore throats, with an average radius of less than 0.7 μm, so they are typical microporous LRPs. Different from LRPs of sandstone and mudstone, they have less tortuous conductive paths than conventional reservoirs, and thus lower resistivity value under the same saturation. Archie’s formula is applicable to the saturation interpretation of LRPs with a cementation index value of 1.77-1.93 and a saturation index value of 1.82-2.03 that are 0.2-0.4 lower than conventional reservoirs respectively. By using interpretation parameters determined by classification statistics of petrophysical groups(PGs), oil saturations of the LRPs were calculated at bout 30%-50%,15% higher than the results by conventional methods, and basically consistent with the data of Dean Stark, RST, oil testing and production. The 15 wells of oil testing and production proved that the coincidence rate of saturation interpretation is over 90%and the feasibility of this method has been further verified. 展开更多

Agricultural wastes poll,tion became serious after great improvement in technology and the encouragement of production for the government since the end of the World Wai Ⅱ. Economists and environmental scholars suggested that "polluter pays" policy be employed in agricultural pollution control. However, it was hard to implement "polluter pays " policy alone in agricultural wastes pollution.In practice, there were two social faCtors which contrih,ted to the improvement of water quality in the southwest of United Kingdom. One method is to communicate with farmers and then give farmers some advice or exhortation on facilities and management. The other method is to set up a telephone hotline for public to report water quality and probable pollution. Therefore, the consideration and combination of social factors in the control of agricultural wastes pollution are necessary, and important. Edueation of basic natural sciences relevant to agricultural pollution, system management of agricultural pollutants and laws relevant to agricultural pollution is suggested to be the third .social factor that British government can consider. 展开更多

Carbonate reservoir characterization and estimation of fluid saturation seem more challenging in the low resistivity pay zone (LRPZ). The Lower Cretaceous Buwaib Formation is important reservoir in the Persian Gulf. The formation in the Salman Field is divided into three reservoir zones and four barriers and tight zones. These reservoir zones show low resistivity characteristics, high fluid saturation, but good oil production. In some intervals resistivity responses reach less than 1 ohm&bull;m. Petrophysical properties measured from laboratory and logging tools have been combined with thin section X-ray diffraction (XRD) and PNN (Pulse Neutron Neutron). Geological studies define presence of 8 facies from wackeston to packstone. In general, reservoir potential of the Buwaib Formation is under influenced by the development of lithocodium mound facies that along with moderate to high porosity intervals. Micritization and pyritization of digenetic process along with clay-coated grains, carbonate with interstitial dispersed clay have conspicuous impact on LRPZ. Based on XRD analysis, Montmorillonite and Kaolinite of main clays types have high CEC and greater impact on lowering resistivity. To describe pore systems of rocks, the L&#248;n&#248;y method applied to address pore throat sizes which contain mudstone micro porosity related to lithocodium mound facies and uniform interparticle at class 3 Lucia as pore size varies from 0.2 to 10 micron. Some constraints were defined to estimate reliable water saturation that checked by sigma logs. Water saturation is 42%, 34% and 40% respectively in BL1, BL2 and BL3 zones. 展开更多

Objective Antiretroviral drugs covered by medical insurance have been gradually used by people living with human immunodeficiency virus(PLWH)in recent years in China.This study aimed to analyze their willingness to pay(WTP)for antiretroviral drugs.Methods A mixed-methods study design involving a cross-sectional survey and in-depth interviews was conducted.A cross-sectional survey was performed to collect data on the general characteristics,economic status,antiretroviral therapy(ART)status,and WTP of PLWH in 18 Chinese cities from August 2022 to February 2023.Multivariate logistic regression was used to analyze the factors associated with WTP.Representatives of PLWH were interviewed via in-depth interviews,and the data were thematically analyzed.Results Among the 941 PLWH,271(28.80%)were willing to pay for antiretroviral drugs covered by medical insurance.For basic medical insurance for urban and rural residents,PLWH with the following characteristics were more willing to pay:an educational level of senior high school or technical secondary school,having an undergraduate degree or higher,frequently working away from their hometowns,and homosexual transmission.Off-farm workers and recipients of government medical aid were more unwilling to pay.For basic medical insurance for urban employees,PLWH with the following characteristics were more willing to pay:frequently working away from their hometowns;homosexual transmission;personal annual income≥100,000 CNY;and adverse events of antiretroviral drugs.The main reasons for PLWH’s WTP for antiretroviral drugs covered by medical insurance were that the drugs had fewer adverse events and were easier to administer.The main reasons for PLWH’s unwillingness to pay were financial difficulties and privacy concerns.Conclusion Nearly one-third of PLWH are willing to pay for antiretroviral drugs covered by medical insurance.In the future,PLWH with a high WTP can be guided to use these drugs. 展开更多

The importance of valuing environmental resources,especially in ecotourism sites,has become increasingly important over the last two decades.Ecotourism is now considered as an important source of livelihood of local stakeholders in backward regions.Therefore,the preservation of ecotourism sites through community participation seems very important to maintain continued flow of tourists.This study aimed at recognizing the importance of community participation for the preservation of ecotourism sites.For this,this study executed a survey based on non-probability sampling in two ecotourism sites(Garpanchkot and Baranti)covering 100 respondents in Purulia District,West Bengal of India.The central issue of this study was to assess the tendency of community participation for the conservation of ecotourism sites and find the optimum condition for offering participatory labour time.This study showed that the participation of young people is high,and the majority of respondents are aware of the importance in protecting ecotourism sites.Because respondents were too poor to offer money,the contingent valuation method(CVM)was used to elicit their willingness to pay(WTP)participatory labour time for the conservation of ecotourism sites.Respondents’age,income,education level,caste,and their perceived environmental quality had significant relationship with their WTP participatory labour time by applying the ordinary least square(OLS)model.It was found that the mean WTP participatory labour time of each respondent in a month is approximately 3.64 h.The significance of this study is that community participation can improve the sense of belonging,trust,and credibility of ecotourism sites,making them more appreciative of the value and protection of these sites. 展开更多

This study examines the transformative impact of Apple Pay on urban landscapes and socioeconomic frameworks,with a particular focus on spending patterns and retail dynamics in metropolitan areas.By evaluating the adoption levels,the technological support,and the social impact of Apple Pay,the study shows that the service is both a catalyst for the development of digital payment and a sign of an increasing social gap.Although it has rapidly transformed Retail Enterprises and supported the construction of smart cities,especially in major world cities such as New York,London,and Tokyo,the work has brought out notable digital divides.Although Apple Pay,with more than 75%of iPhone users and 9,000 banks in 60 world areas and regions,has impacts that are not the same across urban populations,the study shows that while large format retailers have effectively adopted Apple Pay for value-added services to consumers and enhanced payment efficiency,small businesses encounter significant barriers in implementation.Additionally,the technology leverages smartphone usage and banking relationships,which does not address considerable urban population demographics and deeper issues of technology exclusion and inequality in the contemporary city.Such results call for attaining a just society’s technological advancement for efficiencies while still catering to all groups of urban dwellers. 展开更多
