Term
| What does the natural gas transportation system consist of? |
|
Definition
complex network of
pipelines, designed to quickly and efficiently transport natural gas
from its origin to areas of high natural gas demand
• It is closely linked to storage and should the natural gas being
transported not be required all that time, it can be put into storage
facilities for when it is needed |
|
|
Term
| What are the 3 major types of pipelines alon the transportation route? |
|
Definition
• The gathering system
• The interstate pipeline
• The distribution system |
|
|
Term
| What is the gathering system? |
|
Definition
• It consists of low pressure and low diameter pipelines that transport
raw natural gas from the wellhead to the processing plant |

Term
| What are interstate pipelines? |
|
Definition
Interstate pipelines carry natural gas across state boundaries and in
some cases across the country |
|
|
Term
| What are intrastate pipelines? |
|
Definition
| Intrastate pipelines transport natural gas within a particular state |
|
|
Term
| Describe interstate pipelines. |
|
Definition
• This network transports processed natural gas from processing plants
in producing regions to those areas with high natural gas
requirements
• Natural gas that is transported through interstate pipelines travel at
high pressure in the pipeline and at pressures anywhere from 200 to
1500 pounds per square inch
• It reduces the volume of the natural gas that is transported as well as
providing propellant force to move the natural gas through the
pipeline |

Term
| What are the two basic types of local distribution companies? |
|
Definition
• Those owned by investors
• Public gas systems owned by local governments |
|
|
Term
| How do local distribution companies typically transport natural gas? |
|
Definition
Local distribution companies typically transport natural gas from
delivery points along interstate and intrastate pipelines |
|
|
Term
|
Definition
The delivery points to LDCs especially for large municipal areas are
often termed |
|
|
Term
Who take ownership of the natural gas at the citygate and deliver it
to each individual customers's location of use? |

Term
| How many miles of distribution pipe are in the US? |
|
Definition
|
|
Term
| How do large companies reduce unit cost of natural gas? |
|
Definition
by transmitting large volumes
of natural gas, distribution companies must deliver relatively small
volumes to many more different locations |
|
|
Term
| Distribution of natural gas includes: |
|
Definition
moving smaller volumes of gas at much lower
pressures over shorter distances to a great number of individual
users
• Natural gas is periodically compressed to ensure pipeline flow,
although local compressor stations are typically much smaller than
those used for interstate transportation
• The natural gas to be distributed is typically depressurized at or near
the citygate as well as scrubbed or filtered to ensure low moisture
and particulate content |

Term
| What are the components of residential natural gas prices? |
|
Definition
Commodoity prices 45%
Distribution to customers 41%
Transmission to gas company and storage 14% |
|
|
Term
| What are electric meter reading systems? |
|
Definition
• Consumption by any one customer is measured by on-site meters
which essentially keep track of the volume of natural gas consumed
at that location
• New electronic meter-reading systems are capable of transmitting
this information directly to the local distribution company
• Supervisory control and data acquisition (SCADA) systems can
assimilate gas flow control and measurement with other accounting,
billing and contract systems |
