ABSTRACT The effectiveness of Terminalia catappa (tropical almond) and Tamarindus indica (tamarind) as corrosion inhibitors for stainless steel in 1M hydrochloric acid at 30°C, 40°C and 50°C was investigated in this research. The gravimetric method of analysis was employed for 20 days at a 4-day interval using 0.9, 1.1 and 1.3g/15mL of... Continue Reading
Abstract Biodiesel is a renewable fuel that will soon be fully accepted in the commercial world but there are limitations to its use that need improvement. The use of oxygenated additives have improved the burning/fuel qualities of conventional diesel and gasoline. These oxygenates may also improve the qualities of biodiesel. This paper focuses on...

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... 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
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...

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
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...

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
ABSTRACT 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
Abstract 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
Abstract 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,...

Abstract 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
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.
