Abstract In this report, we perform a comparison of two gas condensate stabilization techniques: fractional distillation and multi-flash vaporization. Our prime objective is to compare relevant parameters .e.g. Reid vapor pressure (RVP) and associated costs in order to determine the more effective method for the stabilization of our gas condensate feed. The Aspen Plus software application suite was extensively used for the process design and simulation as well as the economic analysis for thi...
ABSTRACT The maximum recoverable oil in place from the reservoir is a major challenge when it comes to EOR which is an essential part of every oil production project. In some cases, the natural drive mechanism is a relatively inefficient process and results in a low overall oil recovery. The lack of sufficient natural drive in such reservoirs has led to the practice of supplementing the natural reservoir energy by introducing some form of artificial drive, the most basic method being the inje...
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 CO2 and H2S 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 gas. In this project, we design an acid gas removal plant based on the amine treatment process using ASPEN HYSYS software. In our propose...
The ability to analyse the performance and forecast the production of gas wells is important in gas reservoir engineering. Information like the reservoir permeability, damage and improvement, reservoir pressure etc should not be faulty because when faulty, estimation of information that involved them will also be faulty which will in turn depicts wrong forecast of the gas well. To obtain a reasonable degree of accuracy, different analytical methods have been studied and applied to modern gas ...
The objective of primary cementing operation is to provide zonal isolation while drilling oil and gas wells. To achieve this purpose, cement slurries are designed by adding additives to control certain properties such as density, free fluid, compressive strength, rheology, among others. These additives are imported whereas Ghana produces large amount of agro-waste yearly causing environmental nuisance, though these have the potentials of being used in the petroleum industry. The extender, a l...
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 recovery. In this work, the textural, reservoir, physical and chemical properties of oil sand in Nigeria were compared with that in Canada where the t...
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 model for predicting sweet generalized corrosion and the Papavinasam model for predicting localised corrosion which are both insufficient to accurately...
Abstract A pyrolysis reactor was designed and fabricated for the production of bio-esters used in formulating green lubricants for the drilling industry. Samples of Tectona Grandis, Eucalyptus Torreliana, Jatropha Curcas leaf and Cornhusk were each pyrolysed in the reactor at 5000C. Bio-oil obtained was analyzed for their Density, Acid value, % FFA and Viscosity at ambient conditions. Bio-oil was upgraded by esterification using Methanol and synthesized Silica Sulphuric Acid (SSA) as c...
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 the metocean data obtained from hindcast and measured data, this gave an insight to the characteristics of the measured data and how it closely relat...
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 information as far as facts about corrosion is concerned. To ensure this work satisfies the quality expected of it, an experiment was carried out by th...
ABSTRACT Deregulation is the removal or simplification of government rules and regulations that constrain the operation of market force. In course of studying the effect of deregulation, various economic model will be applied to data gotten from the Nigerian National Petroleum Corporation NNPC for efficient and workable economic policy that will bring a sustainable development to both the sector and the country as a whole. This work analyzes the various implications removal of subsidy wil...

ABSTRACT Demulsification (emulsion breaking) is necessary in many practical applications such as the petroleum industry, painting and waste-water treatment in environmental technology. Chemical demulsification is the most widely applied method of treating water-in-crude oil emulsions and involves the use of chemical additives to accelerate the emulsion breaking process. The effect of chemical demulsification operations on the stability and properties of water-in-crude oil emulsion...
