Abstract
Purpose
This paper aims to analyze the pressure behavior in dual porosity reservoirs using different techniques in an attempt to correctly characterize reservoir properties. Pressure transient tests in naturally fractured reservoirs often exhibit non-uniform responses.
Design/methodology/approach
The pressure transient tests in naturally fractured reservoirs were analyzed using conventional semi-log analysis, type curve matching (using commercial software) and Tiab’s direct synthesis (TDS) technique. In addition, the TDS method was applied in case of a naturally fractured formation with a vertical hydraulic fracture. These techniques were applied to a single-layer, naturally fractured reservoir under pseudosteady state matrix flow. By studying the unique characteristics of the different flow regimes appear on the pressure and pressure derivative curves, various reservoir characteristics can be obtained such as permeability, skin factor and fracture properties.
Findings
For naturally fractured reservoirs, a comparison between the results semi-log analysis, software matching and TDS method is presented. In case of wellbore storage, early time flow regime can be obscured that lead to incomplete semi-log analysis. Furthermore, the type curve matching usually gives a non-uniqueness solution, as it needs all the flow regimes to be observed. However, the direct synthesis method used analytical equation to calculate reservoir and well parameters without type curve matching. For naturally fractured reservoirs with a vertical fracture, the pressure behavior of wells crossed by a uniform flux and infinite conductivity fracture is analyzed using TDS technique. The different flow regimes on the pressure derivative curve were used to calculate the fracture half-length in addition to other reservoir properties.
Originality/value
The results of different field cases showed that TDS technique offers several advantages compared to semi-log analysis and type curve matching. It can be used even if some flow regimes are not observed. Direct synthesis results are accurate compared to the available core data and the software matching results. It can be used to confirm the software matching results and to give reliable reservoir characteristics when there is lack of data.

Abstract
Purpose
The purpose of this study is to assess the correlations between the e-entrepreneurial intentions, attitude toward e-entrepreneurship, subjective norms, perceived behavior control, attitude toward risk and entrepreneurial knowledge of Jordanian business students to start an online business and the e-entrepreneurial intention.
Design/methodology/approach
A sample of 392 undergraduate business students from different Jordanian public and private universities participated in the study. Data were collected using an online survey-based questionnaire (i.e. Google Forms) using emails and social media platforms (i.e. WhatsApp, Facebook, etc.); reliability and validity tests were ensured. This study employs a 50-item questionnaire (distributed online via Google Forms and in two languages) to collect data, utilizing 5-point Likert scales; correlation analysis, linear regression analysis, and structural equation modeling are used to analyze the data.
Findings
The results showed that the e-entrepreneurship intentions of Jordanian business students are significantly predicted by their attitude toward e-entrepreneurship, subjective norms, perceived behavioral control, and entrepreneurial knowledge. One’s attitude toward risk does not influence the ambition to launch an Internet company much. Furthermore, their affiliation does not significantly impact the students' plans to pursue e-entrepreneurship.
Practical implications
The study has important real-world implications, particularly for Jordan. The country could create more jobs and boost the economy by encouraging students to start online businesses and helping small businesses grow. This is especially important in Jordan, where many people, particularly young adults, struggle to find work. Therefore, true need for interventions to foster e-entrepreneurship among business students in emerging economies like Jordan.
Originality/value
The goal of this research is to examine Jordanian business students' aspirations to launch Internet businesses in developing nations throughout the digital age. The results offer valuable information on the elements influencing the e-entrepreneurial intents of Jordanian business students. This information may be utilized to create programs and policies that effectively encourage e-entrepreneurship in Jordan.

Abstract
Purpose
The purpose of this research is to explore the influence of the pandemic on manoeuvring consumption decisions towards goods and encouraging the trial of local food goods in a developing country, Jordan; primarily by taking an internal look into country image from a local perspective. Given the lack of studies analysing the impact of crises on consumption decisions, this research highlights the hidden benefits of the pandemic in shifting the perceptions of local food goods among Jordanian consumers.
Design/methodology/approach
This study adopts an exploratory approach to obtain rich, descriptive data to aid in the understanding of the shift in country image perceptions after the COVID-19 crisis and associated influences on purchase intentions. Using a qualitative open-ended approach eliminates the boundaries of closed-end methods of experimental research. Due to the nature of the phenomena being explored in this research, this study adopts the approach of responsive interviews with 26 participants.
Findings
Findings indicate that participants’ perceptions of country image and local goods and their consumption changed responding to COVID-19 for different reasons, creating new norms and perceptions of country image and local food goods. The findings precisely indicate a shift from negative to positive perceptions of country image and local food goods due to the pandemic. Results reveal that there are inconspicuous benefits associated with the role of the pandemic in shifting perceptions of country image and local food goods in Jordan.
Research limitations/implications
Consumers’ perceptions and consumption decisions continue reciprocally to respond to and reflect on the COVID-19 crisis. Adjusting to the new normal is now the focus of research to understand the variance in consumption decisions across the world, including in emerging markets such as Jordan. Results also extend research on cue theory, as crisis seems to have a moderating role in the extent of influence cue theory has on perceptions of goods.
Practical implications
Assisting local brands in improving their marketing strategies, by identifying the barriers that hinder the “desire to try” phase among Jordanian consumers.
Originality/value
To the best of the authors’ knowledge, this study is unique and first of its kind, as it investigates perceptions of Jordanian consumers of their country’s image and whether the perceptual change in their country image would also stimulate a shift of perceptions in local food goods concerning the COVID-19 crisis. The results provide new insights into understanding consumer behaviour and preferences in crises; and the inconspicuous benefits that a crisis may have on local goods.
