» CHAPTER ONE 1.0 INTRODUCTION The Nigerian petroleum industry which has majority of its establishment within the Niger Delta Region has been confronted by two sapping challenges over the years. The challenges relates to the prevalence of militancy and oil pipeline vandalism in the Niger Delta. While …Continue Reading »
» ABSTRACT Well tests exist already for a long time. Since the first oil reservoir was discovered, oil companies have always been keen on estimating reservoir properties such as size. Present day well testing has gone beyond this and its usefulness cannot be overemphasized. This project work is …Continue Reading »
» ABSTRACT Evaluation of reservoir performance for petroleum reservoirs require accurate knowledge of the volumetric behavior of hydrocarbon mixtures, both liquid and gaseous. Prior to the evaluation of reservoir performance, coefficient of Isothermal oil compressibility is required in transient…Continue Reading »
» 1.0 INTRODUCTION Used motor oil is a very dangerous polluting product. It contains PAH’s and high levels of metals. PAH’s such as benzo[a]pyrene, are well known for their high carcinogenity. Considerable quantities of heavy metals such as Pb, Zn, Cu, Cr, …Continue Reading »
» ABSTRACT Every Natural gas well ceases producing as reservoir pressure depletes. The usual liquid presence in the reservoir can cause further problems by accumulating in the wellbore and reducing production even more. There are a number of options in well completion to prevent liquid loading even…Continue Reading »
» ABSTRACT Energy demand in the world today is increasing rapidly and energy generation and resources in the world are incapable of catering for this increase in demand. In third world countries such as Nigeria, energy generation is epileptic; this is evident in the electric power sector of Nige…Continue Reading »
» CHAPTER ONE INTRODUCTION 1.1 BACKGROUND TO THE STUDY There has been a relative slow rate of growth in the Nigerian Petroleum sector for past decades with a far reaching influence of foreign presence. It is a well known fact that the Petroleum sector in any economy requires great a…Continue Reading »
» ABSTRACT A poor description of the reservoir characteristics usually poses a unique problem in exploration and production there by leading to poor development and management of a reservoir field to yield optimum profit required. An accurate description is thus a vital key to an improved field dev…Continue Reading »
» CHAPTER ONEINTRODUCTION1.1 BACKGROUND OF STUDY In the production system, Pressure drop has been a major issue in the field. These pressure drops could be experienced as a result of valves and fittings installed, due to friction along pipe sections or in lifting fluid up to a certain level. As …Continue Reading »
» CHAPTER ONE INTRODUCTION 1.1 Background of the Study The need for resource rich Nigeria to assume control of the exploration, exploitation and production activities in the oil and gas sector and to harness the potentials of this most strategic industry in order to generate more value …Continue Reading »
» ABSTRACT The technique used worldwide while drilling is known as overbalanced drilling. Which is defined as the drilling process where the hydrostatic pressure used exceeds the formation pressure. This is done with the main purpose of “killing” the well. However, there are numerous problems t…Continue Reading »
» CHAPTER ONE INTRODUCTION Many reservoirs are comprised of relatively young sediments, which are so poorly consolidated that sand will be produced along with the reservoir fluids unless the production rate is reduced significantly. Sand production leads to many numerous production problems i…Continue Reading »
» Introduction Hydrocarbons(oil and gas) are found in the pore spaces of sedimentary geologic formations (reservoir rocks). Once an oil or gas reservoir is discovered and assessed, production engineers begin the task of maximizing the amount of oil or gas that can ultimately be recovered from …Continue Reading »
» ABSTRACT Foam are substances that are been formed when pockets of gases are trapped in a liquid or solid. Foam stabilizations are caused by van der waals force between molecules, there are conditions required for foaming to occur. Foams have different applications that are been utilised in the…Continue Reading »

» ABSTRACT Monitoring and maintenance is a continuous process in the various phases of a well’s life. One of the essential part of monitoring is well testing. Just as a regular medical checkup is advised for humans so is well testing advised for a target formation. Well testing provides a means o…Continue Reading »
» CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY Composite is the combination of a matrix and a reinforcement, which when combined gives properties superior to those of the individual components (Ashori & Nourbakhsh 2009a). Wood plastic composite (WPC) is therefore a combination of wood and …Continue Reading »
» ABSTRACT In the present day oil and gas industry, the chemicals used as pH controller are usually imported at an exorbitant price which take a large part of the drilling cost and have ripple effect on the economy of the Nation. It is however necessary to source for an alternative by the use of…Continue Reading »
» ABSTRACT The design of natural flow and artificial lift tubing strings for the whole life of a water drive reservoir was carried out using data based on synthetic reservoir performance based on a material balance. The effects of reservoir properties on the life of the well were also investigated.…Continue Reading »
» ABSTRACT Pressure build up data in low permeability reservoirs take too long and are usually of poor quality. A pressure buildup test is perhaps the most widely performed transient test. In pressure buildup test, a well which has been producing for some time at a constant rate is shut in and the …Continue Reading »
» ABSTRACT Cuttings transportation during in non vertical boreholes is necessary for oil and gas wells. Adequate cuttings removal from a well in drilling is critical for cost effective drilling as high annular cuttings buildup often leads to high risk of stuck pipe, reduced rate of penetration and …Continue Reading »
» 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 p…Continue Reading »
» ABSTRACT The scope of this work was to make detailed analysis of phase distribution in a horizontal pipe. This detailed analysis has been successfully carried out. Data obtained from wire mesh sensor (WMS) were used for the analyses. The operating fluid considered was an air/silicone oil mi…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 use…Continue Reading »
