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.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
