PREDICTING POST BREAKTHROUGH PERFORMANCE OF WATER AND GAS CONING

Water coning is a serious issue for the oil and gas industry. This poses a bigconcern regarding the costs that to be incurred for separation and equipmentcapacity. Coning is the production of an unwanted phase with a desired phase. Overthe years, many techniques and control methods has been birthed, however, the issueof coning can only be mitigated and not completely discharged. Reservoir andproduction engineers need to understand the basic framework; the parameters thatgreatly influence coni...

Nano Augumented Biosurfactant Formulation for Oil Recovery in Medium Oil Reservoirs

Production from most oil field using waterflooding has proven not to produce residual oil due to numerous factors. Several recovery mechanisms have been applied which to an extent has its own influence both on the environment, percentage recovery and also the cost of purchase. In this blending process the bio-surfactant derived from jatropha oil at different concentrations were augmented with nanoparticles for core flooding experiment. A blend of Bio-surfactant and nanoparticles (...

APPLICATION OF TAGUCHI APPROACH IN THE OPTIMIZATION OF THE MECHANICAL PROPERTIES OF SNAIL-SHELL-FILLER/CHICKEN-FEATHER-FIBRE POLYMER BASED HYBRID COMPOSITE

Many studies are on-going to optimize the properties of composites, this is because composite have found application in different industries due to their advantage of light weight. Scientists have turned their attention to using natural occurring materials for the development of novel materials. Animal waste is playing an important part in this area of application as using it is not only providing benign environmental solution but solving engineering challen...

GEOTECHNICAL CHARACTERIZATION OF LATERITES STABILISED WITH SAWDUST ASH-LIME AS SUBGRADE MATERIAL IN ROAD CONSTRUCTION

ABSTRACT Samples  of  laterites  classified  by  American  Association  of  State  Highway  and  Transportation Officials (AASHTO) as A-7-6 and A-7-5, collected from two different borrow pits in Ado-Ekiti were tested for the assessment of their geotechnical properties in natural and stabilized states. The research is aimed at assessing effects of sawdust ash (SDA), lime and the combination of sawdust ash and lime (SDAL) on the proper...

Modular and 3D-Design of a Fluidised Bed Boiler with Agricultural Residue for Steam Energy Production

Abstract: In this study, a miniature fluidised bed boiler for steam generation was designed and constructed. The boiler ismade up of a steam drum, combustion chamber, downcomer and riser tubes as a heat exchanger, a non-return valve andsuperheater tube. Experimental investigation on the fuel distribution was carried in two-dimensional chamber with crosssection of 500 mm x 1000 mm and bed height of 77 mm, 47 mm and 27 mm. The results obtained from the performanceevaluation of the fluidised bed...

FIRE MONITORING, PREVENTION AND CONTROL SYSTEM FOR MARKET SHOPS

Supreme likelihoods of fire disasters in buildings from consulted literatures includes: abnormal rise in temperature, gas leakages from gas cylinders and her accessories, and increasing concentration of smoke from burning materials. On this premise, three respective sensors were saddle with the responsibility of monitoring any anomalies from the aforementioned likelihoods of fire in market shops of which their presence above threshold possess a treat to lives and properties. These sen...

A Review of Soil Dynamics in Traction Studies

As the world population increases more than ever before and increasing demand on food, feed andfiber, and security, the number of off-the-road vehicles is rapidly increasing for agriculture, forestry,military, mining and construction industries. Many researchers have studied and still investigatingtraction as it relates off-road vehicles and publications abound especially from developed countriesof Europe, America and others. In our generation scientists are trying to put robotic vehicles on ...

Development of a Single Wheel Test Rig for Measuring Motion Resistance

Research on soil-wheel interaction is essential in studies of motion resistance of narrow wheels ofagricultural machines. The aim of this research was to study the effects of soil moisture contentand tyre inflation pressure on motion resistance of narrow wheels using a locally developed singlewheel test rig. A single wheel Test Rig facility was developed at Federal University of Technology,Akure. It consists of a soil bin, carriage, single narrow wheel tester, trolley and drive system. Anexis...

Assessment of the effects of lime and cement on geotechnical properties of laterites

Abstract- Two different samples of soil tested as A-7-5 and A-7-6 were stabilized respectively with lime and cement. The samples were stabilized with the additives in steps of 2% and subjected to laboratory tests such as consistency limits, compaction, California bearing ratio (CBR) and unconfined compressive strength (UCS) until it reached 10% additives by weight of dry soil sample. The Proctor energy type of compaction and soaked method of CBR was adopted for the research while the compress...

DEVELOPMENT OF A CASSAVA MASH SIEVING MACHINE FOR GARI PROCESSING OPERATIONS

Limited or poor food separation techniques into fine particles for further processing causes post-harvest losses of food crops and initiates the problem of food and nutritional insecurity in Nigeria. In order to solve this problem, food crops needs to be processed into a lasting and nutritious consumable form through the use of mechanization. Different type of material in powder form or solid form is separated by using two-level screening machines. This machine can be used in different indust...

INTEGRATING THE USE OF PROJECT BASED LEARNING IN TECHNICAL AND VOCATIONAL EDUCATION: A CASE OF GSTC COMPUTER CRAFT DEPARTMENT IJEBU-ODE, OGUN STATE.

AbstractVocational and Technical Education (VTE) is one of the manpower development programmes of study that is attracting the attention of various countries around the world. Numerous studies on Didactics have demonstrated the effectiveness of student centered methods and strategies to improve results in terms of knowledge, skills, attitudes and values in Technical and Vocational Education and Training (TVET). With the continuous advancement of technology, computer technology has infiltrated...

Braking Pattern Impact on Brake Fade in an Automobile Brake System

Abstract. The importance of brake systems in automobiles cannot be overemphasized. Brakes are used in speed control of vehicles and do so by the conversion of kinetic energy into thermal energy. Better stopping performance has favored the disc brake system over the drum brake system and has found wide application in high-performance vehicles. Brake fade, caused by thermal overload has placed a limit on the permissible temperature at which braking systems can function, and it is the...

Modification of an adapted maize jab planter

ABSTRACTThe metering device is a key segment of planters that legitimately influence crop improvement and yield dependent on the presentation of the specific design. Metering device B (Teflon) is intended to minimize seed damage during planting while improving metering efficiency and field capacity. An improved local jab planter for maize seeds which is adjusted for farmers developing under two hectares has been structured, built and tried. The major components of the planter are hopper, seed...

Optimal Location and Sizing of Distributed Generation in Distribution Network Using Adaptive Neuro-Fuzzy Logic Technique

The growing gap between electric power generated and that demanded is of utmost concern especially in developing economy, hence calling for measures to argument the existing power generated of which DG is a more viable aspect to explore in curtailing this challenges; although been confronted with issue of location and sizing. This research applied Adaptive neuro fuzzy logic technique to optimize DG location and size. A 24 bus radial network was used to demonstrate this process and having a su...
