UNIVERSITY OF ABUJA Faculty of Engineering Department of Chemical Engineering First Semester 2019/2020 Academic Session Examination Reservoir Engineering (CHE 817), 3 Units Instruction: Answer Question 1(Compulsory) and any other 3 questions Time allowed 3hrs Question 1 a) An incompressible fluid flows in a linear porous media with the following properties: \( L= \) \( 2000 \mathrm{ft}, \mathrm{h}=20 \mathrm{ft} \) width \( =300 \mathrm{ft}, \mathrm{k}=100 \mathrm{md} \quad \phi \mid=15 \% \mu=2, \mathrm{P}_{1}=2000 \mathrm{psi} \mathrm{P}_{2}=1990 \) psi. Calculate the flow rate in bbl/day. b) State the basic six driving mechanisms that provide the natural energy necessary for oil recovery c) The Big Butte field is a combination-drive reservoir. The current reservoir pressure is estimated at \( 2500 \mathrm{psi} \). The reservoir production data and PVT information are given below: Calculate the initial oil in place. The following additional information is available: Volume of bulk oil zone \( =100,000 \mathrm{ac}-\mathrm{ft} \) Volume of bulk gas zone \( =20,000 \mathrm{ac}-f \mathrm{t} \) 30 marks Question 2 a) What is enhanced oil recovery (EOR) and why is it necessary in the oil production b) What are the types of reservoir classification according to fluid types. Sketch a well labelled diagram of two types
