An oil well has a formation pressure of 2500 psi and a bubble point pressure of 2500 psi. A production test resulted an oil rate of 48 bpd and a water rate of 72 bpd at a measured Pwf of 2000 psi. Calculate the following and plot the results to create an IPR curve for this well.

a. The maximum oil, water and total fluid rate possible.
b. The oil, water and total production rate with a Pwf = 500 psi.
c. Determine the Water Cut (%) at Pwf test, Pwf = 500 psi and at Qmax total fluid.
d. Create the Inflow Performance Curves on a Pwf vs Q graph for this well.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
