Strength and Fracture of Earth-Based and Natural Fiber-Reinforced Composites
(2010-12-15)
This study examined the mechanical properties of earth-based materials that are relevant to the future development of affordable housing. Earthcrete structures were produced by mixing various proportions of laterites, clay ...
Gold Nanoparticle for Medicine
(2010-12-15)
Gold nanoparticles were synthesized by reducing aqueous chloroauric acid (HAuCl4) with three different bacteria. Various microorganisms were verified to see how feasible they will be in synthesizing gold nanoparticles. ...
An Experimental Model to Predict and Control Oilfield Emulsion Tightness: a Novel Approach
(2010-12-12)
Formation of water-in-oil emulsions are among the major challenges encountered by production and surface facilities engineers during the recovery of crude oil, especially in a large multi-wells system in both onshore and ...
Optimization of Strategies for Natural Gas Utilization: Case Study of the Niger Delta
(2010-12-12)
Nigeria is endowed with huge proven gas reserves estimated to be 184 trillion cubic feet (Tcf). It ranks as the 7th holder of natural gas reserves in the world, and the largest in Africa. Nigeria also flares more natural ...
Prevention of Hydrates in Pipelines using Hybrid Thermodynamic Inhibitors
(2010-12-12)
Chemical method is the most efficient and flexible method of hydrate control in offshore operations. In recent times, polymers and surfactants have been used to influence the kinetics of hydrate growth and coagulation. ...
Building and Ranking of Geostatistical Petroleum Reservoir Models
(2010-12-12)
Techniques in Geostatistics are increasingly being used to generate reservoir models and quantify uncertainty in reservoir properties. This is achieved through the construction of multiple realizations to capture the ...
Diagnostic Plots for Analysis of Water Production and Reservoir Performance (A Case Study)
(2010-12-12)
The research is aimed at the understanding of the various diagnostic plots for the analysis of water production that are available as well as the application of these methods in a case study. It also aimed at the establishment ...
Effect of Gas-Oil-Ratio on Oil Production
(2010-11-15)
Maximum production from an oil well can be achieved through proper selection of tubing size. The selection of optimum tubing size must be evaluated when completing a well in any type of reservoir especially solution gas ...
Clay Filtration of Microbes and Fluoride
(2010-06-07)
Consumption of contaminated water may result in several water-borne diseases, including hepatitis, typhoid, cholera, dysentery and other diseases that cause diarrhoea. One of the ways this problem can be prevented is by ...
