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… Continue Reading
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… 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
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… Continue Reading
This is a review of The HP HT wells in Niger Delta.… 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
The effect of liquid flow rate, pipe size (diameter) and pipe orientation (inclination) on liquid hold-up was investigated. Liquid flow rate between 500 STB/day and 5000 STB/day was studied. An oil of 25˚API at an average temperature of 175˚F, a gas gravity of 0.65, water cut of 25% with water gravity of 1.07 and containing no free gas… Continue Reading
Hydraulic fracturing has been an effective technique to stimulate damaged wells or wells producing from low-permeability formation. It has been established that the orientation of a hydraulic fracture is perpendicular to the direction of the least principal stress in the formation. Thus, most pressure transient analysis techniques are… Continue Reading
Hydraulic fracturing is an effective well stimulation technique which is introduced in the 1950s and widely used in the oil and gas industry. Most of the works about hydraulic fracture assumed that the fracture is symmetric and either vertical or horizontal. But, several field and laboratory observations show very complex fractures,… Continue Reading
Solution gas drive reservoirs are characterized by rapid and continuous decline of reservoir pressure. This rapid and continuous decline of reservoir pressure causes direct decline of reservoir performance at early stages of the life of the reservoir. The principal source of energy which is gas liberation from the crude oil and the… Continue Reading
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 was also investigated. Constraints such as maximum production, maximum… Continue Reading
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… Continue Reading
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… Continue Reading
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
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… Continue Reading
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… Continue Reading
Purpose: The main purpose of this empirical work is to identify (if any) the coherentrelationship between the concepts of competition and profitability of firms in the Nigeriandownstream oil industry, using Forte Oil Plc. (FO) as a case study. And consequently, drawup recommendations… Continue Reading
In the present work, STAR-CCM+ CFD code was used to investigate steady state thermal hydraulic parameters in the core of Ghana Research Reactor-1 (GHARR-1). The core was segmented into 21 axial segments. 3D-CAD parametric solid modeler embedded in STARCCM+ was used to model the geometry. The geometry was discretized by the use of… Continue Reading
Robotic is an electromechanical system, help improve production accuracy, and reduces time and increase production. In this project a study of 3D robotic ARM design, simulation concepts and theories for the painting of cars that deals with the design, construction, operation, and application of robots is conducted. The simulation covers… Continue Reading
This research is centered on the design and fabrication of copula furnace and atomizer for the production aluminium powder metal with the available material.0.4kg of refined coke was chosen as the basis for material and energy balance calculations and the design calculations performed from whose values are used to produce the design… Continue Reading
Packaging of food which is viable means of business opportunity has been exploited by individuals and corporate bodies for a very long time because the importance of packaging food products are very enormous ranging from protection of the product to preventing the food from spoiling. There is no way one can successfully go into business… Continue Reading
An escalator is a moving staircase conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal. Escalators are used around the world to move pedestrian traffic in places… Continue Reading
Brazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel as based filter material in air or atmosphere the braze joint will porous and braze strength is not achievable. To avoid the… Continue Reading
