Consumers of a product should not only be concerned about the product package, design and its model but most importantly should be concerned about the ingredients that come into play in making these products. This research was undertaken to study the consciousness of consumers of product contents on product labels, before, during and after consumption. The objectives of this research were to find out whether customers pay attention to the inscriptions of product content information on product labels, and also find out customers understanding of product content labelled on product. The convenience sampling technique was used in selecting the sample of 100 (hundred) customers from the population considering the large number of consumable products consumers in Ho. Respondents were interrogated using questionnaire. Computer data analysis Statistical Package for the Social Sciences (SPSS) was employed to analyse the data in order to help interpret results. It was discovered during this research that more than half of the sample size have knowledge about the product content inscription. It was also found out that just a little below majority buy any product that is packaged. The high percentage disagree to the proposition that once a product is packaged it is fit to buy. Contradictory to the general perception that people do not bother about content inscriptions on product labels, this research proves otherwise. In the nutshell, it was recommended that Health Regulatory bodies, Na-

A coupled reservoir/wellbore simulator is essential for solving relevant flow phenomena with dynamic interactions between reservoir and wellbore in two-phase flow systems. A reservoir simulator or wellbore simulator alone fails to solve these transient flow phenomena. This paper summarises a critical review of the coupled reservoir and wellbore simulation. First, a wide application of the drift-flux (DF) models to simulate gas–liquid flow in a wellbore model coupling to a reservoir model was discussed. Then, the mechanisms of the coupled reservoir/wellbore simulator in two-phase flow systems were discussed, including the reservoir modeling, wellbore modeling, and their coupling schemes. Various examples of representative coupled simulators were presented. Finally, some case studies were reported to reveal dynamic interactions between wellbore and reservoir by using the coupled reservoir/wellbore simulators. This study gives the most up-to-date and systematic sights on the relevant research topic of reservoir/wellbore coupling, allowing for a better understanding of the coupled reservoir and wellbore simulation and its application in the oil and gas industry.
