Vaca Muerta

Abstract Vaca Muerta is an unconventional reservoir located in Argentina. Since 2014, 397 horizontal wells have been drilled in this formation. The scope of this paper is to summarize the evolution of the productivity and the economics of these wells from 2014 until 2020. The methodology consisted in analyzing the results of the wells grouped by drilling campaign extracting the main parameters such as peak oil rate, cumulative oil at 365 days, number of fracture stages and length of the drain. After the extraction of these parameters we calculated each well's EUR using a modified hyperbolic function. A statistical analysis of the results was performed in order to calculate a "Type Well" for each drilling campaign. An economic evaluation for each campaign was then generated in order determine the "Type Well" economics. Once this was achieved we calculated the production profile of an "Economic Type Well" for each campaign defining this as the well which would generate an NPV=0$ at a discount rate of 10%. This was used to determine how many wells were economical for each year. The results of this study show the big impact on the productivity generated by the increase in well length and the number of frac stages revealing the progression of the "Learning curve" for the Vaca Muerta basin including the reduction in Capital Expenditures per well. At present, Vaca Muerta represents an opportunity as a profitable play due to the high productivity of the reservoir and low risk. Nevertheless, there is still room for improvement in the wells' cost according to the results of this study. This paper presents the evolution of the economics and the risk performance of Vaca Muerta.

Objectives: This research was undertaken to examine the economic benefit of mechanization in dehusking arecanut. Methods/Statistical analysis: A sample consisting 15 each of pre-harvest contractors, arecanut farmers using machines of different capacities for dehusking arecanut were randomly selected from Davanagere district of Karnataka. The economic viability of mechanization was assessed under these situations using partial budgeting technique. Findings: The results of the study indicated that the cost of dehusking one quintal of arecanut using machine was ₹141 as compared to manual method (₹276) in case of pre-harvest contractors. The per quintal cost of dehusking of own arecanut produce came to Rs.78 as against manual method(Rs.277)in case of farmers who used the machine for dehusking of their own arecanut produce and rental purpose. Application/Improvements: The study suggested that marginal farmers should use two gear machine, small farmers four gear machine and large farmers six gear machine to economize dehusking their own farm produce and earning rental income.

The World

Tourism and poverty’s phenomenon had already been known since the birth of human civilization. In the 1980s poverty became a serious concern of practitioners and scholars in various part of the world, including Indonesia. Poverty is not only understood in understanding as an abstract concept, but also as a reality of economic injustice and inability to meet basic human needs in some rich countries but also in many developing countries in the world. The problem of poverty is a fundamental and tourism is one of the many ways to solve this. The objective of this paper is to study the role of tourism to poverty alleviation including: 1) to analyze the influence of tourism development toward economic performance; 2) to analyze the effect of economic performance on poverty eradication; 3) to analyze the influence of tourism on poverty alleviation; 4) to formulate a strategy to increase tourism's role in poverty alleviation in Badung Regency. This study uses quantitative approach supported by secondary data and qualitative approach using primary data obtained through observation, in-depth interviews and focus group discussions. Research was conducted in South Badung Regency in the most developed tourism growth and considered the richest district among all regencies in Bali Regencies. Various attempts have been made to alleviate poverty, however have not been able to resolve poverty problems. The grand theory of this study refers to Neoliberalism Theory, supported by Social Democratic Theory and Empowerment Theory. Neoliberalism emphasizes that poverty as an individual problem and prosperity can only be achieved by achievement of economic growth through free market mechanism. According to Social Democratic Theory the emergence of poverty came from outside of the community itself. While the emphasis on the Empowerment Theory is in improving the ability of individual or communities to become indepedence on economic, social welfare and political right. Data analysis using Partial Least Square (PLS) with statistical analysis descriptive and inferential statistics. In order to have a better understanding on the statiscal result, Descriptive Analysis is also used to describe the researched data, using inferential statistical analysis to test the research hypothesis. The results of the research indicated that: 1) the development of tourism showed positive and significant impact on economic performance; 2) economic performance showed negative and significant impact on poverty alleviation; 3) tourism development showed negative and significant effect on poverty alleviation and (4) in order to be able to increase tourism's role in poverty alleviation in Badung Regency the strategy is formulated by analyzing the strengths, weakness, opportunities and challenges based on Strength, Weakness, Opportunity and Threat (SWOT) strategy.

Survey Responses

We argue that survey responses to economic evaluation questions exhibit instability and can be affected by fairly trivial changes in questionnaire wording. Our analyses make three empirical contributions to this area of survey research. First, we demonstrate that within the course of the interview there is considerable instability in economic evaluations. Second, one source of this instability is cues regarding economic performance, such as those provided by the media. We find that respondents can be persuaded to change their economic evaluations if they receive contradictory cues. Finally, we demonstrate that question placement can affect economic evaluations. More specifically, we demonstrate that proximity to political questions can contaminate economic evaluations. If economic evaluations closely follow political preference questions, respondents have a tendency to give economic responses that are “consistent” with their political responses. Our empirical analysis is based on economic evaluations of respondents to the Hungarian Markets and Democracy Survey administered during December 1997.

The Relationship

This paper presents a statistical analysis of the relationship between economic performance and competitiveness indicators to address the question of the extent to which competitiveness indicators provideuseful information when assessing economic performance. The analysis was performed on various examples of African economies. The possible relationships between economic performance and competitiveness indicators were examined by extending a basic relationship between economic performance per capita and investment by competitiveness indicators. The models were estimated by means of an Arellano-Bond estimator. The authors detected many statistically significant relationships between economic performance and competitiveness indicators in the cases of both the whole sample and specifically middle-income economies. However, in the case of low-income economies there are no discernible relationships between economic performance and the information included in the competitiveness indicators. The paper contributes to the analysis of the economic performance of African economies, for which the empirical evaluation of possible links between economic performance and competitiveness indicators is altogether missing.

Abstract In the Experimental Farm of the Universidade Federal de Lavras (EF-UFLA), state of Minas Gerais, Brazil, on their day of birth, female Holstein calves were randomly selected and placed into two groups containing fifteen animals each: Strategic-Selective Treatment (S-ST) or Conventional Treatment (CT). In the S-ST, calves were treated after coproparasitological examinations according to criteria established previously by the researchers. Calves in the CT were treated according to the opinion of the veterinarian of EF-UFLA. For statistical analysis, the frequency (%) of fecal samples with count of eggs per gram of feces (EPG) ≥300, count of oocysts per gram of feces (OoPG) ≥500 and fecal samples with count of cysts of Giardia spp. ≥1 were conducted. The overall average frequency of fecal samples with EPG ≥300, OoPG ≥500 and Giardia spp. cysts ≥1, respectively, was similar (p >0.05) between S-ST (20.3%; 17.3%; and 31.5%) and CT (26.4%; 23.9%; and 37.3%). The effective operational cost, per animal, in 12 months, was of R$ 784.58 (US$ 241.41) and R$ 83.90 (US$ 25.81) in S-ST and CT, respectively. The S-ST requires adjustments to be used as a technically efficient and economically viable alternative for the control of gastrointestinal parasitosis in female Holstein calves.
