he hepatitis B virus is spread between people through contact with the blood or other body fluids (i.e. semen, vaginal fluid and saliva) of an infected person, while the hepatitis C virus is spread through direct contact with infected blood. Very rarely it can also be passed on through other body fluids (Redmond, 2007). Many people infected with hepatitis B or C rarely displays any symptom, although they can still transmit the virus to others. Hepatitis B is a major disease of serious gl... read more

n Ghana, 2,062 new breast cancer cases and 1,137 breast cancer deaths were estimated annually (16.5% of all women cancer deaths), with age-standardized incidence and mortality rates of 25.8 and 15.2 per 100,000 women, respectively (Globocan 2008).[1] Sixty percent of cases were detected at late stages (IIB, III and IV).[8] The available data on median age are limited and mainly hospital based. Clegg-Lamptey et al. reported a median age at diagnosis of 43 years on a sample of 66 women newly diagn... read more

he classic waterborne enteric pathogens include Vibrio cholerae (serogroups O1 and O139, causing cholera), Salmonella enterica (subsp. enterica ser. Typhi, causing typhoid), and Shigella spp. (four species causing dysentery), which have largely been controlled by water treatment/disinfection and are therefore rarely an issue via drinking water in developed regions. However, person-to-person and foodborne spread maintains Shigella sonnei within the sewage of developed regions, along with closely-... read more

renatal exercise is of benefit to every pregnant mother. Exercise can reduce the length of labour, shorten the recovery time and even help with post-partum weight management (5). The physiotherapists in the hospital always come to the clinic as early as possible but they usually meet only few pregnant mothers because they come late to the clinic for the exercise as they see little or no need for prenatal exercise. The purpose of this study is to study how pregnant mothers perceive usefulness of ... read more

ogram. A high pH is desirable to suppress corrosion rate, hydrogen embrittlement and the solubility of Ca2+ and Mg2+ which makes up clay. In addition, the high pH is a favorable environment for many of the organic viscosity control additives. For years this additives use to help maintain this property are imported and this contribute to high cost of drilling and which adversely affect the economy. In order to minimize this cost and maximize profit ,the locally made additives is been investigate... read more

This project propose a key measure to prevent indiscriminate disposal of these principal wastes and absorption of crude oil in water, apart from punitive enforcement of legislature. This is to develop technological solutions by providing alternative use for these waste materials which will place a value on them. Identifying the potential use of waste to create job and inadvertently help in shaping public attitude towards its disposal and create job in the long term. Saw dust wastes are n... read more

btained from the well test data. Hence, the importance of analysis. There are various methods used to analyze well test data such as manual plotting, excel analysis and software analysis. In this study, a build-up test data was obtain from an XYZ field for two dual string oil producing wells (4 wells) and was analyzed using a tool called Saphir. The result from tool showed the properties of the reservoir required for characterization i.e. pressure, permeability and boundary conditions. It was ... read more

n oil or gas reservoir is discovered and assessed, production engineers begin the task of maximizing the amount of oil or gas that can ultimately be recovered from it. Some reservoir rocks may allow the oil and gas to move freely, making it easier to recover. Other reservoirs do not part with the oil and gas easily and require special technique to move the oil or gas from the pore spaces in the reservoir rock to a producing well. Even with today’s technology, in some reservoirs more than two-t... read more

The method to be adopted for this project is the use of sieve analysis and sucier correlation to determine the gravel pack size to be used for OBEN WELL 13 with formation sands gotten from the case study as mentioned above and useful information gotten from the internet, textbooks, petroleum journals. This method simply involves collecting core samples and running them through different sieves with different opening sizes, usually sieves with larger openings at the top and sieves of smaller ... read more

ifferential pipe sticking, loss of circulation, formation damage and other problems. A relatively new technique was introduced, known as underbalanced drilling, where the well is being drilled with a hydrostatic pressure less than that of the formation. Correct and proper execution of such technique eliminates problems associated with overbalanced drilling. More precisely, underbalanced drilling solves the issues of formation damage, differential pressure sticking and loss of circulation. On the... read more

Definition of terms Local Content:Is the development of local skills, oil and gas technology transfer, and use of local manpower and local manufacturing. For a more practical definition, one could say that local content is building a workforce that is skilled and building a competitive supplier base (Oil and Gas, 2010). Oil and Gas industry:A company that participates in every aspect of the oil or gasbusiness, which includes the discovering, obtaining, producing, refining, and distributing... read more

t is important to accurately predict the pressure drop accross a production system. This has been a difficult task in the oil and gas industry as the production system in real life is not homogenous (single phase) as assumed in most theories. The reason for this is that the two-phase flow is complex and difficult to analyze. Ideally, gas moves at a much higher velocity than the liquid. As a result, the down hole flowing pressure of the liquid-gas mixture is greater than the corresponding pressur... read more

A poor description of the reservoir characteristics usually poses a unique problem in exploration and production there by leading to poor development and management of a reservoir field to yield optimum profit required. An accurate description is thus a vital key to an improved field development planning and management. This study illustrates how an integration of empirically determine oil effective permeability data was correlated as a function of average reservoir pressure. This is to pr... read more

The cost of fossil fuel, inclusive of cost of procurement, processing and utilization when considered alongside the deficient power generation from this energy source especially in developing countries is of exorbitant nature . Fossil fuel is in a state of decreasing availability. This unfavorable situation when considered w... read more

Every Natural gas well ceases producing as reservoir pressure depletes. The usual liquid presence in the reservoir can cause further problems by accumulating in the wellbore and reducing production even more. There are a number of options in well completion to prevent liquid loading even before it becomes a problem. Tubing size and perforation interval optimization are the two most common methods. Although completion optimization will prevent liquid accumulation in the wellbore for a certain tim... read more
