A car is traveling at 20 mi/h on good, dry
pavement at 5000 ft elevation. The front-wheel-drive
car has a drag coefficient of 0.30, a frontal area of 20 ft2
and a weight of 2500 lb. The wheelbase is 110 inches
and the center of gravity is 20 inches from the ground,
50 inches behind the front axle. The engine is producing
95 ft-lb of torque and is in a gear that gives an overall
gear reduction ratio of 4.5. The radius of the drive
wheels is 14 inches and the mechanical efficiency of the
drivetrain is 90%. What would the acceleration of the
car be if the driver was accelerating quickly to avoid a
collision?

a) 3.65 ft/s2
b) 15.53 ft/s2
c) 15.90 ft/s2
d) 3.48 ft/s2

You have been asked to review the performance of a combination
solution gas, gas-cap drive reservoir. Well test and log information show
that the reservoir initially had a gas cap half the size of the initial oil
volume. Initial reservoir pressure and solution gas-oil ratio were 2500 psia
and 721 SCF/STB, respectively. Using the volumetric approach,
initial oil in place was found to be 56 MM STB. As you proceed with the
analysis, you discover that your boss has not given you all the data you
need to make the analysis. The missing information is that at some point
in the life of the project a pressure maintenance program was initiated
using gas injection. The time of the gas injection and the total amount of
gas injected are not known. There was no active water drive or water
production. PVT and production data are in the following table:

a) At what point (i.e., pressure) did the pressure maintenance program
begin?

b) How much gas in SCF had been injected when the reservoir pressure is
500 psia? Assume that the reservoir gas and the injected gas have the
same compressibility factor.
