Review of Radial Drilling Technology and Viable Prospect in Mature Field Development in the Niger Delta
Abstract: A review of some Niger Delta oil field reservoirs indicates that most of the reservoirs are at the mature stages, thereby vulnerable to challenges such as; coning due to reduced size of the oil column, low oil production and lack of access to the residual oil trapped between existing wells of the mature field. Due to coning occurrences in the Niger-Delta oil field, most wells have been shut-in and a …

Homocysteine and Pregnancy Outcome
Abstract: High total homocysteine (tHcy) measured in serum or plasma is associated with pregnancy complications, congenital malformation and other adverse pregnancy outcomes. The Hordaland Homocysteine Study(HHS) is a population-based study, in which large population were studied, plasma levels of total homocysteine (tHcy) were associated with several physiologic and lifestyle factors and with common diseases. Among the factors associated with increased plasma tHcy levels are: increasing age, male sex, smoking, coffee consumption, …

A Comparative Study on Associated Factors of Hypertension Among Working Women and Non-working Women
Abstract: Background: One in four people worldwide is affected by high blood pressure, which is also the third leading cause of illness and a significant risk factor for death. Compared to non-working women, employed women had a higher prevalence of hypertension. This might be attributed to various factors such as job-related stress, lack of relaxation, and lack of physical activity. Method: Quantitative approach was adopted. To investigate the related determinants of …

Injection Pressure Optimization for Non-edible Biodiesel Blends in CRDI Engines: A Comparative Study
Abstract: The growing demand for clean and sustainable energy has increased interest in biodiesel produced from non-edible oil sources. These fuels are renewable, biodegradable, and do not compete with food resources. However, the effective use of biodiesel blends in modern diesel engines requires proper control of fuel injection parameters, particularly injection pressure. In common rail direct injection (CRDI) engines, injection pressure strongly influences spray formation, air–fuel mixing, combustion behaviour, and exhaust …

Breathing prediction of fracture deviated wellbore through flooding mechanism
Abstract: Wellbore breathing is a common occurrence during drilling operations, but the down hole mechanism and how it manifests itself in surface and subsurface processes, is not well understood. It often result in a drilling fluid gain at surface and are misidentified as a kick, resulting in unneeded shut in periods and associated non-productive time (NPT). Further, misidentification of wellbore breathing as underbalance often results in increases in mud weight, which …
