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 local materials so as to enhance cost effectiveness.... 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 their different forms. Defoamers are substances that... Continue Reading
ABSTRACT Hydrocarbon production in the petroleum industry is often constrained by reservoir heterogeneity, deliverability and capacity of surface facilities, also optimization technique in the petroleum industry requires execution of several iterative runs by comparing various solutions until an optimum or satisfactory solution is found. In this... 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, Ni, and Cd are contained in used crankcase oil, these... 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 it. Some reservoir rocks may allow the oil and gas to... Continue Reading
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 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 Nigeria. Issues such as Environmental degradation and... 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 including erosion of down hole tubular, valves, fitting and... Continue Reading
ABSTRACT Despite its numerous benefits the search and production of crude oil poses a lot of dangers to the environment. Among these include land, water and air pollution. Prominent among the major sources of E&P waste is drilling operations which form the second largest source of waste after production activities. The major drilling wastes... 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 that accompany overbalanced drilling. Such problems... 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 amount of technology, capital with seasoned and experienced... Continue Reading
SYNERGISTIC EFFECT OF DATURA STRAMONIUM LEAVES EXTRACT - Z2n+ ON THE CORROSION INHIBITION OF MILD WELLWATER ABSTRACT The synergistic effect of Datura stramonium leaves extract and Zn2+ in the corrosion inhibition of mild steel in aqueous medium (100ml well water) was investigated in this project. The corrosion inhibition studies were carried out... 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 before it becomes a problem. Tubing size and... 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 of obtaining information about the well and the...

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 other impediments to standard drilling and...

ABSTRACT Petroleum Fiscal System (PFS) is a major determinant of investment decision in the exploration and production of oil and gas in any country. It basically describes the profitability relationship between the host government of the producing community and the International Oil Companies (IOCs). The comparative analysis of the performance of... 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 One of the major challenges in reservoir engineering is the accurate description of the reservoir. This description is essential in all aspects of petroleum engineering, and is typically achieved through reservoir characterization by integrating various kinds of information obtained from the reservoir. One reliable source of reservoir... Continue Reading
ABSTRACT This research work was carried out to evaluate the laboratory analysis of pipeline products marketing company (PPMC) depot operations.
