ABSTRACT Petroleum reserves are affected either negatively or positively by the type of fiscal system and elements governing them. Governments, investors, policymakers, and other stakeholders have from the past been a victim of the difficulties of the reserve recognitions. This has influenced investment decisions as well as affected the attractiveness of the project. By the use of economic indicators for analysis, the host government will be able to design an efficient fiscal system and the ...
ABSTRACT The need to re-develop one of the Brown fields located in the Niger Delta area of Nigeria was necessitated by the fact that there are still three undeveloped reservoirs in the field. A total of six stacked reservoirs, A100 to A600 (all oil bearing with associated gas) were penetrated between 8552 ftss and 10652 ftss by APV-1 well. Reservoir blocks A200 and A600 are the largest in the field accounting for 77% of the total field STOIIP. The well was completed with a Two String Multipl...
ABSTRACT Proper handling of sour gas produced is crucial to the development of sour reservoirs. Over years of research and practice, many methods of sour gas processing have been developed from the solid storage of sulfur to reinjecting the sour gas back into producing or depleted light oil reservoir for miscible flooding enhanced oil recovery. This paper seeks to investigate the use of sour gas to enhance oil recovery and its associated phase behavior problems. In designing a miscible gas f...
ABSTRACT This work is aimed at studying activated carbons as supercapacitor electrode materials derived from plant biomass waste materials. The activated carbon raw materials are sourced from coconut shell, pine cone and rice husk plant biomass. The chemical activation route is employed with KOH as an activating agent. The carbonization temperature used is 800 oC and the carbonization time is varied from 1 h to 5 h. Activated carbon of high surface area and porosity are achieved and their el...
ABSTRACT The consideration of pipe eccentricity and its impact on hole cleaning has not been widely reported in literature. Pipe eccentricity affects the average velocity of the drilling fluid in the annulus which is one of the most important factors considered in hole cleaning. In this study, developed equations of motion for a couette flow of non-Newtonian power-law fluid through an eccentric annulus are used to determine the effect of pipe eccentricity on hole cleaning. A graph for the ve...
ABSTRACT Conventional methods used in determining initial gas-in-place and reserves for a dry gas reservoir entails the use of P/z vs cumulative production data. In a normally pressured gas reservoir, the only important production mechanism is the compressibility of the gas. Many reservoir engineering calculations take advantage of this fact to simplify analysis. However, in deep geopressured gas reservoirs, the compressibility of the gas is much smaller and does not totally dominate product...
ABSTRACT Reservoir development planning and well placement significantly affect hydrocarbon recovery. Therefore, strategic well placement and development techniques are essential to minimize the risk of unproductive drilling and also to maximize production within the reservoir. This study presents an approach to well placement and production in a green field. A 3D static model of the green field was built using geostatistical techniques to distribute the various model petrophysical propertie...
Abstract The design, construction and performance test of a parabolic solar cooker for domestic use are presented. The simple experimental parabolic solar cooker, made of locally available materials, consists of a parabolic dish of thickness 0.3mm, adjustable mechanism, pot, pot holder, base support and a reflecting glass surface. The concave surface of the dish was lagged with reflective glasses which serve as a reflecting surface. Commercially available (3mm) thick glass is used as glazing...
ABSTRACT In this project work, a hybrid cloud system using StackOps Distro Community Edition was designed and implemented. The Electrical and Electronic Engineering Department of the Federal University of Technology, Owerri was used as a case study. This is essential as there is greater need for readily available and on-the-go Information and Communication Technology services. Ubiquitous access to data, files, documents, project work and the like are vital in all spheres of life, and especia...
ABSTRACT A preliminary study was made on the effect of castor oil on the properties of polyether based polyurethane foam such as rising time, density, hardness tensile strength, compression, elongation and heat aging. The castor oil was introduced into the polyurethane foam by partially substituting it for silicone oil through seven experimental set up, based on the laboratory mix formulation on 5OOg polyether based polyol with 0%, 20%, 40%, 50%, 60%, 80% and IOO% castor oil substitutions.
ABSTRACT The purpose of this project was to design and develop a Computer Based Testing (CBT) system in order to facilitate the process of conducting e-examinations especially in tertiary institutions. There is a growing need to find an easy and effective way to carryout continuous assessments for the increasing population of students. The CBT system will afford instructors the opportunity to assign different weights to the multiple choice questions. The method adopted was a client/server b...
ABSTRACT This work builds on an earlier work done which used global coordinates where a large number of elements were needed to form a convergence of results for shop built spherical pressure vessels. In this work area coordinates were used. Any action that leads to an inability on the part of a structure to function as intended is known as failure. This research, therefore, investigates stresses developed in a shop built carbon steel spherical storage vessels using finite element approach...
ABSTRACT An evaporative cooling system was developed with locally available materials. The system was aimed at providing lower temperature and higher relative humidity necessary for extending the shelf life of fruits and vegetables. The performance of the cooler was evaluated in terms of temperature drop, humidity gain, cooling efficiency and quality assessment of the stored products. Two categories of test were carried out on the cooler with the chosen absorbent materials: the no-load test a...
ABSTRACT An indirect, natural convection solar-assisted charcoal smoking system was designed and fabricated in one of the host communities of the Federal University of Technology, Owerri where most of the fish farmers and processors adopt the conventional method of drying fishes, that is, using firewood. This method which works well during the dry period of the year is very inconvenient during the rainy season. Given the excessive heat generated by firewood and its resultant effect on the...
Abstract Consumers’ complaints of estimated bills from the Utility have risen to an alarming extent in recent years. On the other hand, Utility incurs huge losses attributing it to electric energy consumption theft among consumers. These complaints by the utility and the consumer led to the quest for a system that in addition to recording energy consumption data, will be able to compute and report the data to the Utility remotely. This work proposes the implementation of smart meter which...
