This paper presents dataset on the beneficiation of a Nigerian claymineral for drilling mud application. The experimental designapplied used a Response Surface Design (RSM), which involved 24(2-Level, 4-Factors) to generate statistical models, and analyze thedataset. The independent variables were (Bentonite; X1), (Polymer;X2), (Sodium Carbonate, X3) and (Aging Time; X4). The rheologicalproperties of interest, which forms the response variables, wereselected based on the API specification 13-...
A design of experiment was used to create oil rim models from a wider range of reservoir, operational andreservoir architecture parameters. A response surface model was generated based on a concurrent oil and gasproduction and a Pareto analysis was conducted to ascertain the significance of the parameters. The models wereclassified based on the Pareto analysis and due to the low oil recoveries arising from the complexity of oil rims, aseries of secondary injection schemes were instigated. The...
The development of gas reservoirs and the key decisions to bemade concerning gas reservoirs such as the number of wells todrill, well fracturing and capacity of the surface processingfacilities are dependent on its productivity. Condensateblockage caused by liquid build up is difficult to control in theaforementioned reservoirs thereby affecting production. In thiswork, production is optimized from gas condensate reservoirsusing horizontal wells. This is to demonstrate the performanceof horiz...
Sidetrack operations which involves accessing a new zone and commingling production gives rise touncertainties and proxy models have shown to be able to incorporate uncertainties and mimic real-lifescenarios to an acceptable degree of accuracy. In this paper, a time-based proxy model which integrates the uncertainties that emerge as a result of several reservoir parameters was developed usingNPV as the objective function. A black oil simulator was used to generate the production profile andNP...
Thin oil rim reservoirs are those with less than a 100 ft. of oil thickness underlain andoverlain by an aquifer and gas cap respectively. Irrespective of the sizes of the aquifer or gas cap,oil rims productivity is usually low due to excessive coning of water and gas. Productionoptimizations are usually carried out before recovery schemes are initiated. One of such is aconcurrent oil and gas production which is used in comparison with sequential production in thisstudy in conjunction with pro...
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...
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 (B-NPs) is a ...
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 challenges. In this study, the effe...
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 properties of the soil samples. The samples were subj...
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...
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...
As the world population increases more than ever before and increasing demand on food, feed and fiber, 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 investigating traction as it relates off-road vehicles and publications abound especially from developed countries of Europe, America and others. In our generation scientists are trying to put robotic vehicles...
Research on soil-wheel interaction is essential in studies of motion resistance of narrow wheels of agricultural machines. The aim of this research was to study the effects of soil moisture content and tyre inflation pressure on motion resistance of narrow wheels using a locally developed single wheel 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. An...
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...
