Petroleum and Gas
Crude oil

 

First American discoveries were in Pennsylvania and were of limited use (demand wise)

Jennings, LA was the first site where oil was discovered in LA

Most of the early exploration was associated with Salt Domes, because that’s where several early discoveries were made, even though it didn’t make a great deal of sense geologically to drill on the top of them.

North Louisiana was better developed early on (1904) near Caddo Lake.

Most of the early development and the best sources were on the Sabine uplift.

 

South Louisiana’s oil and gas industry does not develop until the depression era.

Off-shore drilling begins in the mid-1930s, but only in shallow water.

 

Any further than 3 miles off the shore is federal.  Although LA cannot tax this production, there are considerable multipliers associated with this offshore production.

 

Recently, greater exploration has returned to North LA.  Partly this is a response to new geologic evidence, but also a response to the vast expense associated with off-shore exploration.

Smaller fields in the north. 

 

5.7 billion barrels believed to still be available, making LA 4th to CA, AK and TX.

Refining

Baton Rouge, although it does not have any natural gas or oil has become a major refining center because of its advantageous location as the nearest port to the production fields.

Lake Charles has also become an important refining area.

 

Louisiana has a transport advantage over Texas, which is the other large refining and petrochemical and has better reserves of both oil and natural gas.

 

Other Linkages

Plastics, chemicals and solvents of many sorts

Dozens of other linkages that are small, but an important source of employment include:

Transportation, geology work, research, legal work, ship building, dock working, pipeline construction, housing etc.

Morgan City is a major drilling rig construction zone, with considerable export potential.

 

Environmental Consequences
Exhaustion of a non-renewable resource

Already have lost some 10,000 jobs to depletion of resources.  Could have a situation where many more shut down.  Many companies have reinvested in LA, making the short-term prospects good, especially since the transportation costs of petroleum are low.

Coastal Erosion and Subsidence

Petroleum extraction may contribute to subsidence

Coastal and marsh destruction aided by the exploration and drilling processes in the coastal and near coastal areas.  The construction of canals is particularly damaging.

Pollutants directly into the air water and soil.

 

Hazardous waste disposal.
Boom and Bust Cycles

From $36/bbl down to $10/bbl in 1987 from a peak in 1982.

165,000 directly employed…50K lost in the bust.

New Orleans, 1/4th of the workers involved in petrol industries.

During the early 1980s, Louisiana had moved up to 34th in per cap income, but fell back to 47th in the late 1980s.  It was 39th in 1995.

Severance Tax is what the natural resources tax is called. 

The large percentage of the state budget that is contributed oil taxes has historically kept income taxes etc. very low.

In 1983, severance taxes contributed nearly 1/3 of the state's revenue, in 1996 it was only 7.3 %

The majority of the difference has been made up in sales taxes and income tax.

Gambling has helped some, but cuts have been made elsewhere.

Natural Gas

Reserves are known to be about 31 trillion cu/ft, and most of it is offshore.

 

Natural Gas was not used effectively and openly wasted or burnt off during the early years.

In 1916 gas was better used and a field was struck near Monroe.  (6 trillion cu/ft so far)

 

The off-shore gas fields are impressive.  More than half of the potential production down there is in gas.

Bateman Lake and Bayou Sale both have impressive reserves (3 trillion cu/ft so far)
