Bachelor Thesis from the year 2014 in the subject Engineering - Power Engineering, grade: A, University of Benin, course: Petroleum Engineering, language: English, abstract: Crude oil production is a major requirement to sustaining the well begins of any petroleum company. This will entail the effective placement of all facilities and equipment; surface or subsurface in order to achieve optimum volume of crude oil production, this is usually called production optimization.In this study, the software prosper was utilized to case study well J-12T Well J-12T, a natural producer was producing at its peak oil rate at 6137 STB/d at 0% water-cut by mid-1973 but since then production has been on the decline due to increasing water-cut and decreasing reservoir pressure. But to date, the well is producing at an oil rate of 1431 STB/d at a water-cut of 50%.The VLP/IPR data were matched to well test flow rate measurement with a deviation of about 0,0534%, thereafter a short and long term optimization plan scenarios such as sensitivity runs on the well head pressure, tubing sizes, and gas lift technique respectively etc for the well, were simulated in PROSPER and then evaluated.The results of this work suggests that; by lowering the Christmas tree pressure from 180 to 120psi the well¿s life can be extended to 70% water-cut, also increasing the tubing size from 2,992" to 3,958" ID is also recommended. The gas lift method was found to be more economical as it can produce up to a maximum economic water cut of 90% with optimum gas injection rate of 3.3MMscf/d and oil production rates will increased from 1431 STB/d to about 3000 STB/d at 50% water-cut.

Research Paper (undergraduate) from the year 2012 in the subject Environmental Sciences, , course: Petroleum Engineering, language: English, abstract: Oil spill is one of the most dangerous side effects of crude oil exploration and production in the Niger Delta area of Nigeria. Its resultant effect on the environment, surface body of water, ground water, and biodiversity signifies that if appropriate measures of management are not put in place, the Niger deltäs coastal habitat and inland habitat will no longer be habitat able.This paper examines the prevailing policies and procedure for the oil spill contingency planning in the Nigeria and identifies problems associated with the response action to oil spill incidents in the Niger Delta region. It also proffers solution to the problems, drawing on the wealth of experience gained from the oil spill preparedness and response put in place by some government agencies and operators across the globe. Based on this, the paper proposes a Quantitative risk based approach for the oil spill preparedness and response in the Niger Delta. This approach involves the quantification of risk as result of the probability of an event occurring and the impact potential of the event. Hence hazards and risks can be pre-determined and effective strategies could be developed to mitigate the impacts of potential oil spills.
