Oil & Gas Overview
The Offshore Oil & Gas search page
provides an easy way to locate and compare production numbers by
year and computed dollar value for:
- State and Federal regions
- Total U.S. production
- Associated wellhead price (gas)
- First purchase price (oil) by year, region
The U.S. has 31 states and Federal OCS regions that produce oil
and natural gas. The offshore industry includes: Alabama, Alaska,
California, Louisiana, Mississippi, Texas, Alaska OCS, Pacific
OCS, and Gulf of Mexico (GOM) OCS.
Oil and Gas comes out of the ground in different forms:
- Crude oil is normally classified as light, medium,
heavy, or bitumen (tar sands) based on its physical
properties. Generally, heavy oil is thicker and more
viscous than light oil and therefore must be mixed with a
lighter oil or condensate before it can flow in a pipeline.
- Condensate is a liquid hydrocarbon, which is
associated with 'wet gas.' These production numbers are
included in the NOEP database when available.
- Natural gas is a combustible mixture of hydrocarbon
gases, primarily methane. Other mixtures include ethane,
propane, butane, and pentane. (The propane and butane, which
can account for up to 20% of the hydrocarbons present, are
removed and sold separately.)
