(a) An oil well is producing from an undersaturated reservoir that is characterized by a bubble point pressure of 2500Psig. The current average roservoir pressure is 3000 psig. Available flow test data shows that the well producod 300STB/ day at a stabilized PwF of 2600psig. Construct the IPR data (1e) A saturated oil reservoir is under Consideration to be waterflooded immediately after drilling and Completion. Core analys is tests Indicate that the Initial and residual oil saturations are 70% and 35% respectively. Assume that B0 will remain constant theonghurt the project life. What will the displacement officiency be if the residual oil saturation Was 70% and 80% a) SPDC plans to sell one of their asset in Ankota field in the onshore region of the Niger Delta. The Field have the following conditions: p=3600psi,Pwf=2200psi,re=740ft.rw=0. 3ft,Uo=2cp,Bo=1.4bbl/STB h=25ft,k=60md, Porosity= 0.2. Assuming steadystate flow of an incompressible fluid in the reservoir. i) As a fluid flow engineer, calculate the flow rate of this field in surface condition ii) If the area of flow is 1.7MMft, what is the apparent fluid velocity in ft/ day iii) What is the actual fluid velocity in ft/day? a saturated oil reservoir is under consideration to be water flooded after drilling and completion . core analysis test indicate that the initial and residual oil saturations are 70% and 35% respectively. Calculate the displacement efficiency when the oil saturation is reduced to 60%,50%41% and 35% Assume that Bo will remain constant throughout the project life, What will the displacement efficiency be if the residual oil saturation was 70% and 80%
