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.

a) Sketch the specific energy curves for the following open channel flows:
· A hydraulic jump formed in a rectangular open channel
· Flow through a channel width constriction, where the depths remain subcritical
throughout
· Flow through a sluice gate, where the gate opening is less than the flow’s critical
depth.
· Flow through a combined channel width constriction together with an upward
step, where the depth remains subcritical throughout.
b) Define and explain the following terms
· Critical depth
· The origin or description of the two components of the specific energy for
rectangular channels
· Alternate depths· The origin or description of the two components of the momentum function for rectangular channels

Kanchana has been working as an environmental engineer at a
consulting firm for over twenty-five years. Well-known for settling
disputes between his corporate clients before litigation must be
pursued, Kanchana often analyses technical data, particularly
distributions of solid particle pollution, presented by disputing
parties to help them reach a compromise on the cost of
environmental clean-up. For example, two parties may be separated
from one another by a strip of land; however, each party must
fiscally contribute in keeping the land free from pollutants.
One day, Kanchana was contacted by a journalist to talk about his
experiences at the firm. Kanchana spoke about how he often
encountered cases where companies did not accurately depict levels
of solid particle pollution occupying the companies’ respective
surroundings. Instead, technical experts, who are mostly engineers,
would misrepresent data in order to make it seem that minority
parties were responsible for a greater part of the contamination.
At the end of the interview, Kanchana emphasized the necessity of
engineers taking ownership and being honest about the presentation
of data.

The shallow sandy aquifer (4 feet thickness) is contaminated with 1,2-XYZ (K oc = 20 L/kg) at an average soil concentration of 800 mg/kg. A batch soil washing device is designed to treat 1,100 kg of contaminated soil (f oc = 0.004) with 900 gallons of clean water. Find the concentration of 1,2-XYZ in water and in soil and water after (a) one wash, and, (b) two wash.
