Pressure transient testing provides an indirect determination of reservoir and well parameters, it is one of the most essential techniques used to provide details about the reservoir characteristics and well conditions. There are several tests available to…
Drilling mud are complex heterogeneous fluids consisting of several additives. Cellulose from waste paper are viscosity builder in polymers, its use as viscosifier additive will reduce overall well cost, improve waste anagement while reducing environmental…
Gasoline station workers (GSWs) are occupationally exposed to gasoline daily. Our previous study on the toxicological and biochemical profile of GSWs in Onitsha, Anambra state revealed that GSWs are at risk of benzene and Lead-mediated toxicity. This was…
Liquefied Petroleum Gas (LPG), as a product of natural gas processing that is a mixture of hydrocarbon gases mainly propane, butane, butylene and impurities such as Sulphur compound. LPG production and distribution in Nigeria appeared to have had limited…
The aim of this study is to investigate the effect of process variables during dilute acid pre-treatment and enzymatic saccharification of sorghum stalk for cellulosic ethanol production. The sorghum stalk was pre-treated at different reaction temperature…
This study focuses on the effect cooling rate of different moulds on the microstructure (graphite flakes size, distribution) and mechanical properties of grey cast iron. Two common mould materials namely commercial silica sand and an industrial solid waste of…
Petroleum exploration have been ongoing in the northern Benue Trough Nigeria, with little success in locating commercial oil pool. Clastic petroleum reservoir has been the main exploration target in the region, despite existence of other possible petroleum…
The phenomenon of retrograde condensation occurs when the reservoir pressure declines below the dew-point pressure causing gas condensation and developing two-phase flow. Material Balance Equation (MBE) of gas condensate reservoirs is a challenge because of…
Existing models for performing Nodal Analysis for a production system without displaying charts, has been identified to be somewhat complex and can only be solved by empirical methods. However, in this study, a simplified sub-model (Rotimi and Wilfred model)…
Data acquisition in 3D seismic is influenced by various elements. They may range from lithological features, terrain or environmental conditions to acquisition design parameters, instrumentation, and data collection style. This paper considers the design…
