Acid Gas Treating
Natural gas may have mole fractions of acid gases that if high
enough will decrease the heating content of the gas and its sales
value and will cause corrosion.
Thus, these gases may need to be removed prior to the sale of the
Artificial Lift PGE 379
Homework 2 Solution
Due Feb. 18th.
Let us continue our artificial lift design for the example data used in HWK 1. We will agree to try and
design a beam lift system to produce 400 STBO/day with a WOR of 0.5 BW/BO and an GLR of 1,00

Topic 2 Control Mechanisms
Flow Control at the Surface
Flow from the well is controlled at the surface by a well head with
valves and some type of flow restricting device (called a choke).
A choke is a small diameter tube placed in the flow line that is a
Topic 5 Tanks and
This section will discuss above ground storage tanks for oil field use.
Tanks are temporary holding vessels that allow some volume of oil
and water to be stored at the production facility.
Storage is nec
Topic 6B Gas Dehydration
Gas Processing - Dehydration
Natural gas is saturated with water vapor at what ever concentration
can be supported by the gas pressure and temperature.
Any time the gas is compressed or cooled the water vapor content
Topic 6 Gas Hydrates
Gas hydrates are a combination of natural gas and water.
When the pressure and temperature and gas-water composition are
correct a hydrate will form.
The gas hydrate looks like snow and can accumulate into a frozen
Topic 7 - Gas Compression
Gas must be at the pressure that is required to allow flow into the
next part of a gas processing facility or down a gas pipe line.
The gas compressor acts like a pump for compressible fluids and
raises the pressu
Topic 9 LACT Units
Lease Automatic Custody and Transfer (LACT) units can be used to
take the place of the tank gauger and pipe line representative.
A LACT unit
detects the quality of the oil (BS&W content),
measures the volume of oil,
A very high percentage of the natural gas measurements at
production facilities are taken using a concentric square edge orifice
The orifice is a thin plate with a hole of an exact diameter that is
placed in a flow tube called
