ABSTRACT With the ever increasing need to optimize production, the accurate understanding of the mechanics of multi-phase flow and its effect on the pressure drop along the oil-well flow string is becoming more pertinent. The efficient design of gas-lift pump, electric submersible pumps, separators, flow strings and other production equipment... Continue Reading
ABSTRACT This research work mainly investigates the development and the behavior of cones (both water and gas cones) in oil reservoirs supported by strong aquifer, and from which analytical correlations are developed for quick engineering estimates of the time for water/gas cones to break into the perforations of the producing wells. The studies... Continue Reading
ABSTRACT Maximum production from an oil well can be achieved through proper selection of tubing size. The selection of optimum tubing size must be evaluated when completing a well in any type of reservoir especially solution gas drive reservoir since there is likelihood of producing more gas as the reservoir pressure declines. The most widely used... Continue Reading
ABSTRACT A new method for analysing productivity index (PI) on vertical wells is the main objective of this study. Well performance is often measured in terms of the well’s productivity which is dependent on a number of factors such as the reservoir’s configuration, the type of completion, petrophysical and fluid properties, formation damage,...

ABSTRACT The production of formation sand is a problem associated with most oil deposits in the world. Major Sand production effects affect safety, well or field economics and continuous production. This has prompted the continued search for solutions to mitigate sand production in the oil and gas industry over time. The methodology often employed... Continue Reading
ABSTRACT As the demand for petroleum resources increases, drilling of oil and gas wells are often carried out in challenging and hostile environments. Among the top ten drilling challenges facing the oil and gas industry today is the problem of lost circulation. Major progress has been made to understand this problem and how to combat it. However,... Continue Reading
ABSTRACT The Niger Delta is Nigeria’s and Africa’s most prol ific producing basin and has some untapped oil resources because of their marginality. The development of marginal oil field in Nigeria has now become an important strategic issue. This is due to the vast availability of these fields scattered all over the Niger Delta. The Federal...

ABSTRACT This research work was carried out to evaluate the different methods of corrosion prevention, control and monitoring. In the course of the research many scholarly articles on the subject matter were reviewed from which the researcher got lot information concerning the topic at hand. Thus making the research work a reliable source of... Continue Reading
The aim of the project is to develop a numerical tool used to predict vessel motions of a turret moored FPSO, then perform a comparative analysis between the 6 degree of motions measured on the FPSOs during the 7 months period and the predictions from this numerical model. The first step was to carry out statistical and extreme value analysis of... Continue Reading
ABSTRACT This project work deals on the feasibility of transferring the Toe – To – Heel Air Injection (THAI) technology which is a new in-situ combustion method of heavy oil recovery from Alberta, Canada, where the technology has recorded success with high rate of recovery to South-West, Nigeria (Ondo state) for efficient heavy oil...

Carbon steel corrosion is a commonly encountered issue in pipelines transporting hydrocarbons containing corrosive agents such as CO2, H2S and water. As a result, several corrosion prediction models have been put forward over the years although no standard model exists for corrosion prediction in the industry. Two of such models are the Norsok...

ABSTRACT This research work was carried out to evaluate the laboratory analysis of pipeline products marketing company (PPMC) depot operations. In the course of the research many scholarly articles on the subject matter were reviewed from which the researcher got lot information concerning the topic at hand. Thus making the research work a... Continue Reading
Natural gas is one of the major sources of fuel and raw material to industries all over the world. However, it contains some acid gases such as C O2 and H2 S which are corrosive and harmful to the environment. These acid gases must be brought to permissible limits to promote safety in the operation and increase the heating value of the natural... Continue Reading
This study investigated the concentration of heavy metals in oil field produced water from Niger Delta, before and after treatment with locally sourced agricultural wastes. Two produced water samples were investigated for different metal ions such as; Lead, Nickel, Cadmium, Copper, Iron, Magnesium, Chromium, Zinc, Manganese, Calcium, Arsenic,... Continue Reading

According to Bittner (2015) he argued that in a bid to ensure good community relations, organizations expend shareholders money, cut down workers salaries, waste precious time which should be used for other profitable things. He calls it “a fundamentally subversive doctrine which offers insoluble practical problems”. While Nweke (2001:220) is... Continue Reading
ABSTRACT The study was designed to find out the effects of Inventory Management on Corporate Profit using the Nigerian Gas company as the case study. To achieve this objective, three Null Hypotheses and Alternative Hypotheses were formed to guide the study. All the staff... Continue Reading
Abstract The Niger Delta is on the throes of death caused by the unmitigated exploration, exploitation and production of hydrocarbon which feeds and develops foreign economies at the detriment of the host communities which live in the worst state of neglect by... Continue Reading
ABSTRACT Development and performance analysis of compressed natural gas (CNG) as a transportation fuel for automobiles in Nigeria are presented. The study involved compositional analysis of natural gas obtained from the product sales point at a treatment plant about 10km off the Port Harcourt-Onitsha route chosen to ensure standard sales gas...

The reservoir characteristics of the gas condensate well is special and the changes of the behavior of the well have a significant impact to the production rate. When we do a proper optimization that can lower the operating costs, maximizing HC recovery and the net present value of a project can be increased. The optimization of the well level can...

ABSTRACT The concept of dumpflooding is to flow water from a high pressure aquifer zone to a low pressure oil producing zone by natural force of gravity through a well connecting the two zones to enhance oil sweep into a producing well. The research described is aimed to find solutions to one of the flaws in dumpflooding that is, the inability to... Continue Reading
ABSTRACT A major drawback of directional and horizontal well drilling is the numerous complex computations required to be done while planning a well. These computations are very stressful and time consuming especially when done manually. One of the objectives of this study was to develop a user friendly Excel Spreadsheet program that would make...
