Comparative Analysis Of Reserves Determination Techniques In Overpressured Gas Reservoirs

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 pr...

An Approach Towell Placement And Productionin A Green Field – A Case Study

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 pro...

Design And Performance Evaluation Of A Parabolic Solar Cooker

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 ...

Design And Implementation Of A Hybrid Cloud Using Stackops Distro Community Edition

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 especial...

Effects of Castor Oil on the Physical Properties of Polyether Based Flexible Polyareahane Foam

ABSTRACTA 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 oi...

Design And Development Of Computer Based Test System To Facilitate E-Exam.

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/serve...

Finite Element Modeling of Shop Built Spherical Pressure Vessels

ABSTRACTThis 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 eleme...

Design And Development Of An Evaporative Cooling System For Fresh Fruit And Vegetable Storage

ABSTRACTAn 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 an...

Design And Development Of A Hybrid Solar/Charcoal Fish Smoke-Dryer

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...

Design And Construction Of A Wireless Smart Meter

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 wh...

Design And Construction Of A Robotic Arm With Adaptive Behaviour

ABSTRACT This project work covers the design and construction of a robotic arm mechanically capable of 5 Degrees of Freedom. It solves the problem of automatically detecting and picking up objects placed within distances of 10-30cm round the robot base platform. It does this by using a simplified forward and inverse kinematic relation modeled in two dimensional robot workspace. The work does not cover the more general case, of an n-linked (n>2) robotic arm working within a three dimensio...

Design And Construction Of A 40a Intelligent Charge Controller For The Department Of Electrical And Electronic Engineering

ABSTRACT This project presents a 40A maximum power point tracking solar charge controller. The MPPT charge controller tries to keep the voltage and the power stable. The MPPT charge controller will harvest more power from the solar array – it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load. An MPPT charge controller is an electronic DC to DC converter that optimiz...

Data Mining And Knowledge Discovery In Database For Improved Industrial Safety

Abstract Safety is crucial in oil and gas industries, it is normal practice to collect incident reports daily. The volume of such reports is always very huge, as a result, the interpretation poses a great challenge. Consequently, there is an urgent need for techniques that can intelligently assist in transforming such vast amount of data into useful information and knowledge. Data mining is part of the knowledge discovery process that offers ways of extracting non-trivial, previously unk...

Construction Of Arduino Based Quadruple Auto Power Supply For Domestic Application

 ABSTRACT The problem of epileptic power supply and its consequences in the developing countries is a generally known issue. Worst still, the hope that it will be addressed with the deregulation of electricity Industries in recent time are being dashed by flight to top class investors due to its poor implementation. There is a need to provide multiple sources of power and automatic mechanisms for switching from one source to another. This is achieved in this work where quadruple pow...

Comparative Economic Analysis Of Compressed Natural Gas And Automotive Gas Oil As Automobile Fuels

ABSTRACT Comparative economic analysis of the use of compressed natural gas (CNG) and the use of AGO for power generation was presented. The data for costs of constructing and running CNG-powered vehicles were obtained for the study. Separate economic analyses of running the CNG-powered vehicles and running AGO vehicles were performed. The initial capital cost for CNG project amounted to N4.31 million and that for diesel was N3.60 million while the annual operating cost for CNG is N1.47 milli...
