QUESTION TWO An oil well is producing a crude oil system at 2000 STB/day and 2000 psi of bottom-bole flowing pressure. The pay zone and the producing well have the following characteristics h-35 ft, rw 0.25 ft, drainage area-40 acres, API-45, 7g-0. 72, A-700 scfSTB, &-80 md. Bo 1.1 bbl/STB Assuming steady-state flowing conditions, calculate and plot the pressure profile around the wellbore QUESTION THREE 3a. Figure 2 shows a reservoir with many zones layered in series and parallel flow conditions Calculate the average permeability of the reservoir and the total flow rate of oil through this reservoir assuming pow steady state flow condition. Bo-1.2 bbl/STB. q-2cP. P-2000p ii. O iii. w-son Figure 2: Layered Reservoir 3b. What is the difference between series and parallel flow in a reservoir? What do you think is the significance of this flow pattern in a reservoir? A P-2700pm QUESTION FOUR 4a. SPDC plans to sell one of their asset in Ankota field in the onshore region of the Niger Delta. The Geld have the following conditions: -3600 psi, Par-2200 psi, r-740 ft. -0.3ft, po-2 cp, 8,-1.4bblSTB -25 ft, k-60 md, Porosity-0.2 Assuming steadystate flow of an incompressible fluid in the reservoir. L K-40md K₂-40md 7-201 4x drilling As a fluid flow engineer, calculate the flow rate of this field in surface condition. If the area of flow is 1.7 MMft', what is the apparent fluid velocity in ft/day What is the actual fluid velocity in fuday? saturated oil reservoir and after is under completion saturations 4b. waterflooded immediately tests and residual oil consideration to be that the initial Core analysis Calculate the displacement efficiency when the oil saturation is reduced to 60%, 50%, 41% and 35% are 70% and 35% respectively 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%? QUESTION FIVE An oil well is producing from an undersaturated reservoir that is characterized by a bubble point p of 2500 psig. The current average reservoir pressure is 3000 psig. Available flow test data shows well produced 300 STB/day at a stabilized prof 2600 psig. Construct the IPR data
